In March, 1886, the writer, a tall awkward young man fresh from the fields of Ohio, was traveling by rail through Utah. Near Provo he began to see snug farms with trees, meadows, orchards, granaries and haystacks. S'ome of these stacks had been cut in two with the hay knife, and he noticed with won- der the beautiful green color of the fresh cut sur- face. Calling the attention of the conductor to this phenomenon, so strange to him, he asked, ^'What sort of hay is in those stacks^ " " Lucern, ' ' prompt- ly replied the conductor. ''And what makes it so green f ' ' It 's green because that 's the color of it, ' ' sagely replied the smiling conductor, as he pocketed a cash fare and moved on about his business. At that date lucern, or alfalfa, had not spread much east ^of the valleys of Utah ; some was grown in Col- orado, but it was a new thing there. The Utah farmers were many of them English and Danish, hence their choice of the old name lucern, while the Spanish term alfalfa had come in from Chili by way of California. Late that night the writer reached Salt Lake City and early next morning he was up ready to explore. In his rambles about the quaint old city (more old- world than American at that time with its houses of adobe, its walled gardens and orchards, its rows of towering Lombardy poplars) he came across a (3) 4 AFLALFA FARMING IN AMERICA. square devoted to the hay market. There stood awaiting purchasers dozens of loads of this curious green-looking hay. He went to a load of it and drew out a stem and chewed it to see what it tasted like. To his astonishment it tasted good, much as wheat tastes when chewed. It dissolved in his mouth and tasted as though it would nourish him. ''The best country I have struck yet," remarked the boy to himself. ' ' If ever I get hard up here I can at least go to a haystack and eat lucern hay. I won't starve/* Curiously enough it later came to his knowledge that this first impression was true, that alfalfa hay has really in it nearly the same amount of nutrition, pound for pound, as has oats, and from oatmeal have come mighty good men. Next the boy lived for a time in Salt Lake City and cared for his uncle's cow. She was a fine motherly cow, very wide where width did the most good, low down and gentle, with a big mouth and an appetite to match it. He fed her on alfalfa hay without grain. What milk she gave! That cow must have been a freak, for she gave some 5 or 6 gallons a day of rich creamy milk with no other food than alfalfa hay and hydrant water. Steadily as he milked the cow the respect of the boy for alfalfa hay grew. Next the boy went down into the deep mountain canyons along Green River and worked there on a cattle ranch. It was a great ranch in dimension, full 40 miles in extreme length, extending from the horrid cliffs along Price Elver to the cool heights INTRODUCTION. 5 of the Big Mesa, sloping down to the Nine Mile. Through this ranch ran a little creek called Eange Creek. The soil was sandy and gravelly along the creek, not very fertile. The climate was intensely hot; often the thermometer would climb to 110° and stay there day after day. Cattle and horses were kept on the ranch, some 2,000 cattle at times. In the narrow sandy valley little ditches were made to lead the water from the bubbling creek, idle foT ages though once Cliff Dwellers had farmed along its banks and grown corn, which they had stored in adobe 'and stone treasure houses high up under the cliffs. Now little fields were cleared from their en- cumbering sagebrush and grease wood, the water turned on, and they were planted to corn and al- falfa. It was called lucern then; later the name alfalfa overpowered and became almost universal. At first the alfalfa did not thrive along Eange Creek. It made a small feeble growth, but it stuck. In one field especially, down clo'se to the headquar- ters cabin, alfalfa grew the first year no more than about 6 inches high. The boy, who already had charge of the farm and general charge of all the ranch, was disgusted with it and wished to plow it up and try something else. The soil there was sandy, gravelly, open and rather coarse. An old- timer happening in at the right time counseled against plowing it. ''Let it be; you may have good alfalfa there another year," he said. This advice was heeded ; the next year the alfalfa there grew so high that when the burros would walk out into it only 6 ALFALFA FARMING IN AMERICA. their heads would be visible. It produced four crops of hay and easily 8 tons to the acre. Water for irrigation was very abundant at that time in Eange Valley. It was the custom to flood the land over just before cutting off the hay and once afterward. At that time no one knew anything about soil inoc- ulation and the behavior of alfalfa was a profound mystery. It now occurs to the writer to explain the curious behavior of the alfalfa in this manner: up the canyon a mile or two was an established alfalfa field, not a good stand, but thrifty. When this field was irrigated the surplus water flowed on down to the lower field and went over that. It seems clear now that in this manner the bacteria were intro- duced from the established field to the new one. As long as the writer had connection with this ranch, some twelve years, this field continued to produce heavy crops of alfalfa, though not so wonderfully rank as the earlier growths. Doubtless the excessive irrigation leached away some fertility, and the con- tinual removal of hay without returning any manure or fertilizer told, even on that very deep and per- vious soil. However, the last crops that the writer remembers growing on this field could hardly have been less than 5 tons to the acre. It used to be a great joy to grow alfalfa on this old ranch. Before the alfalfa came there was noth- ing in the valley to relieve the monotony of brown, drouth-stricken nature. The alfalfa fields were vividly green squares and patches, relieving the monotony of brown sage brush and bare earth. The INTRODUCTION. 7 advent of the alfalfa changed the animal life too of the canyon. Before alfalfa came there used to be little animal life save the chipmunks and lizards ; all had fled that could flee to the green mountain -tops. After alfalfa deer came to stay down in the meadows all summer long ; some of them had their little fawns down there. The boy foreman used to see the old does sitanding deep in alfalfa nibbling daintily very early in the morning as he went up to change the water. He would not shoot them; they were his companions. Humming birds too came in great num- bers to sip the sweet nectar of alfalfa bloom. They would sit in quaint rows along the wire fence, peer- ing curiously at the boy as he passed by smiling, shovel on his shoulder. Bees he had none, else there would have been great stores of honey made there. It was joy to grow the alfalfa, because the grow- ing of it was so very easy. The method of sowing was very simple. The fields were first made fairly level. There was a strong slope so that it was easy to get water to any part of them. Then furrows were made with a common turning plow run shallow, or else with a furrow marker that made a number of S'hallower furrows parallel with each other. Then the alfalfa seed was sown, sometimes brushed in with a brush drag, and then a tiny stream of water turned in each furrow and kept running there for days and days, since under that burning sun one could not count on sandy land holding moisture at the surface very long. Sometimes the alfalfa was sown in March, oftener in April. It did not make 8 ALFALFA FARMING IN AMERICA. much hay the first season, hardly any in fact; the second year was when it began to hump itself. By the second year all furrows were pretty well leveled down or washed away; then the land was irrigated by flooding. Large ditches were placed across the heads of the fields, with lesser ones transversely lower down. The head ditches were provided with dams hastily thrown up across them from the sand of the ditch bottom. Then as big a head as could be mustered was turned in and all of it turned out in one place. The irrigator got out with his shovel, often in bare feet, and helped it flow this way and that, spreading it so that it covered that part of the field with an even-flowing sheet of water a few inches deep. When it had flowed a few hours the dam was broken, 'the stream carried further along to another turnout. By this simple plan of irrigation the writer unaided one summer watered about 90 acres of land. That was a happy summer. He had a big white burro, ^^Old Nig,'' which he kept saddled most of the time. Nig knew the work about as well as the boy knew it, and he would gallop merrily up the road to the top of the field in the morning, about two miles from the cabin, stand patiently under a Cottonwood tree till the work was done there; then with his master on deck gallop cheerily down to the next field, and so on till all the water had been given attention. There is a great fascination in working with water and the writer yet thinks irrigation farming one of the finest schemes in the world. The making of 'the hay was hard work, but not INTRODUCTION. 9 accompanied with worry, because usually no rain fell between April and Sep'tember. We used to mow down the alfalfa and rake it while quite green and as soon as possible pile it up in big cocks and leave it there to dry out a while. In that hot sun and baking air the moisture disappeared very rapidly indeed, so that by the time we could get to hauling, the hay would be dry enough, and thus it retained perfectly its color, leaves and delicious aroma. Very joyous times we had at this haying, a lot of harum- scarum cowboys and ranch hands, strong as wild colts and rejoicing to see which of us could lift the largest forkful of hay. At first we simply hauled the hay on wagons and stacked it by hand. Later an ingenious Mormon boy showed us how to rig a pole stacker, and then we let the horse do the pitching. We accumulated great ricks of hay, hundreds of tons, against pos- sible severe winters. Meanwhile we were feeding alfalfa to our saddle and work horses, to poor cows and calves that would have died before green grass came had they not had this help, and occasionally fattening a bunch of beef steers on it for the spring market, when fat beef brings a premium in Denver and Salt Lake City. We had no grain at all and fed only alfalfa hay, making with it very good beef indeed, though doubt- less we would have made much fatter cattle had we had corn to feed along with it. We had a few old sows on the ranch and must make provision for feeding them and their pigs. 10 ALFALFA FARMING IN AMERICA. They were astonisMngly prolific sows and gave us great litters of healthy pigs, so many sometimes that we did no't know what to do with them. The sows were kept penned up nearly the year through and during summer we simply cut alfalfa with a scythe and threw it over 'to them. This kept them in fine thrifty condition and their pigs grew but kept rather lanky on the diet. When fall came we would fatten them off with pumpkins and squashes and alfalfa. In winter time we would vary the diet by giving them dry alfalfa hay and alfalfa leaves. They throve well and it was at first very amusing to see hogs eat alfalfa hay, putting their feet on it to hold it down while they tore it apart with their teeth and chewed it as best they could. It was won- derful to us also to see what fine full udders our milk cows had. Old-fashioned milking Shorthorns they were, of the type that the fathers had. The Mormon settlers had brought with them their best family cows when they came across the range, and we had some of their descendants. We fed these cows only alfalfa hay in winter, and mostly soiled them on green alfalfa in summer, and what splendid foaming pails we carried down from the corral ! We half lived on milk and cream those days, being too busy to make butter. Sometimes we had trouble from alfalfa bloat. That came in the fall, after we had turned the cows on the meadows and they grazed the alfalfa that had come up since the last mowing and gotten badly frosted. We used to have strenuous times with these old cows, tying sticks in INTRODUCTION. 11 their mouths like bridle bits, making them stand with their heads up a steep bank and putting cakes of ice on their distended sides. We never had one die, but learned then that frosted alfalfa is never a safe feed for a cow. Over on the Castle Valley desert were Mormon settlements. Castle Dale, Ferron, Price and other villages. They were on adobe soil mostly, a sad sort of alkaline clay, full enough of minerals but lacking in humus and life-giving properties. The first attempts of these settlers to grow grain were mostly unsuccessful; it would not thrive, and the people were incredibly poor. Little by little they got alfalfa to growing on this alkaline soil and then with cows and pigs and poultry they managed to live quite well. Finally one of them let the water run over his alfalfa in the winter so that it froze into solid ice over his field. This is sure death to alfalfa, unless there is air under the ice, and in the spring he had lost his meadow; nearly every plant of alfalfa was dead. He grieved over this, but set to work to see what he oould get from the land and planted a part of it to spring wheat, though it had previously refused to grow wheat, and a part to potatoes, also a very uncertain crop at that time in Castle Valley. The result was a crop of wheat that made 60 bushels to the acre, a marvel to the whole valley. The potatoes made some unheard of yield, about 900 bushels to the acre, I think, and the for- tunes of Castle Valley with its sun and brilliant skies and wildly desolate plains and crags was assured. 12 ALFALFA FARMING IN AMERICA. These valleys were fertile, they would yield food for mail' and beast, and alfalfa was the magic sesame that made ojjen the door to the riches of the valley. All this time the writer was becoming more and more enthusiastic over the wonderful value of the alfalfa plant. Back in Ohio was the old home farm where he had spent his boyhood. It was a little farm of less than 200 acres, charmingly diversified by little hills, rich flat meadow lands, wet and half wild, in which grew wild lilies and pink fragrant spireas. There was woodland and pasture, a run- ning stream, the Darby creek, with swimming holes in it, a big pond where he had sailed his tiny ships not so very many years before, a corn field, usually of about 15 acres, meadows in irregular patches, and an old apple orchard that bore famously 'of big red apples. On that farm tO'O was an old man once tall but now bent and gray, weatherbeaten, seamed and furrowed from exposure, with a kindly serious face and a twinkling blue eye. That was the father. And a mother, small and agile and energetic, rather frail yet sunny and happy, ever singing at her work. That was mo'ther. And two younger brothers did the work about the barns and went to school. These younger brothers, men now, are yet on Woodland Farm and are the writer's partners. The writer had been a very close friend of his father, and together they had planned the work on Woodland Farm before he had gone west, and now the old man remembered his boy and knew of his interest in the old place, so he used to write now INTRODUCTION. 13 and then long and careful letters telling of what he was doing, of the drains that he was laying, or the good corn that he grew. And the boy in his very first enthusiasm for the alfalfa plant sent home a package of seed by mail (that was in 1886) and asked the father to give it space and soil and care. And often in his daydreams he would ponder the question of returning some day to the old farm. He would dream idle dreams of what he might do there, how he might enrich it and plant it and maybe buy neighboring acres to add to it. Somewhat more than two years rolled away and the boy took a vacation and went back to the old home, to see the home folks, and a sweetheart he had there. It is a very joyful and rather a wonder- ful thing to come home after having been exiled to a strange land. The deserts of Utah were like an- other world, so that when the boy came to Ohio it was as though he had come to a dream world, so beautiful, and so natural and so lovely it all seemed. How eagerly he explored his old haunts, one by one! What old memories were stirred into life as he saw the meadows, the woodland, the hill planted to corn and kept immaculately clean of weeds, the orchard, the garden; the dear old father, stooped and aged more than the boy remembered him, went right to his heart; the mother, silvery haired now; the sister and young brothers! The sweetheart was of course unspeakably marvelous and wonderful, and it all was as though the boy had been born again into a new world. Soon after his arrival, as he explored 14 ALFALFA FARMING IN AMERICA. with diligence, he asked the old man: ** Father, where is my alfalfa? Did you plant that seed that I sent you V '' Why, yes, I planted it, but it did not amount to anything. This is no country for alfalfa. It may do for you in the West, but it is of no use here ; but come and see it, what there is of it." Back of the garden the old man had spaded a square rod of good clay soil and sowed his seed. He led the way and pointed accusingly to the stunted little plants scattered thinly over the ground: ''There, don't you see that this thing is no good for OhioT' The boy stood in amazement looking at it, so dif- ferent from what he had fondly hoped it might be. His father turned away and left him, but still he stood studying the situation. Soon happened along a flock 'of his mother's fowls; they came to the alfalfa patch and began an eager search for leaves ; one by one they plucked them oif till nearly every plant was stripped bare, then walked away. ' ' Aha ! ' ' cried the boy; ''I see a light now," and he went to the well and pumped a tub full of water, which he carried and emptied carefully down by the strongest root that he could find. It was early August and the land was dry. To keep away the chickens he took an old barrel, knocked the heads out of it and put it over his alfalfa plant. In a little more than three weeks he was ready to go back to his work on the ranch and he went to say good bye to his alfalfa patch. To his delight the stalk of alfalfa had thrived for its wetting and its protection and had grown out through the top of the barrel! Joyfully INTRODUCTION, 15 the Iboy called his father, "Come here; see what my alfalfa has done!" And the sire, amazed and be- wildered at first, stood there scratching his old gray head and smiling an amused, puzzled smile. Finally he turned and said: "Son, do you suppose that I want to grow a crop that won't grow till you put a barrel over it T ' The lad laughed and said no more, but went back to his mountains and the alfalfa fields, remembering the one stalk of alfalfa that had succeeded and saying, "I know that alfalfa can be grown in Ohio. If one stalk will grow as that one grew, why can't a man grow a thousand! If he can grow a thousiand, why can't he grow a million, why can't he cover his farm with alfalfa!" The ranch was not just the same to the boy when he came back to it, not just the same because he had ever before him the image of the sweetheart left be- hind. Yet it was a happy place, and he went tumul- tuously into the work again, strong as a young giant, eager to do, finding no day long enough for him. Now was time of happy dreams, and after a time the dreams began to materialize as he mixed mud and made "adobes," or "dobies," as the boys called them, and hauled down logs from far up the canyon, for She was coming and a house must be made ready for her. There were wonderful letters coming, too, and often the boy would be seen on Sundays sitting far up on the rocky hillside, away from the confusion and talk of the cowboys, reading the last letter that She had written, or writing one in reply to it. The work 16 ALFALFA FARMING IN AMERICA. of the ranch was much the same as it had been save that the ricks of alfalfa grew larger and larger each year and the problem of making and using the hay grew to be portentous. The mountains remained the same always, and the boy loved them deeply and climbed them eagerly, going up where never white man had been before, just to gaze off afar to other snowy ranges, and across sunny yellow valleys in the desert, beautiful from afar. All the cowboys loved him and worked faithfully for him; every one worked as hard as he could and the cattle waxed fat on a thousand hills. In November it was that the letter came, the letter written in that familiar crabbed yet plain handwrit- ing that the father used. Nearly always the father's letters gave the boy much pleasure. He opened this one expecting it to be like the others that had come, but it was a shock to find in it a totally different note. It read like this: "My boy, I wish you to come home. Times are hard back here; hired men are no good any more. I am getting old and infirm. I need you very much. Come home and help me with the farm. I do not see how I can get along without you longer." The letter gave the boy a rude shock. All at once he realized how he loved the wild ranch with its free- dom, its responsibility, its opportunities for doing things. He loved every hill and every mesa and every canyon. Half of the canyons he had named, some of them he only had ridden through. He loved the sun and air, the yellow bunchgrass, the INTRODUCTION. 17 solemn pines. He loved the horses that he rode and the great herd of cattle in his charge, and his com- rades, rough as bears and loving as brothers. So he carried the letter in his pocket with a sad heart for a day or two, when little Billie Barnson, who was riding beside him, turned to him and said: ''Joe, what in thunder is the matter with you? Has your girl gone back on youf "No, Billie, that is not what is the matter, ' ^ and in a few words he laid bare his heart; he ought to leave the mountains, perhaps forever, and he dreaded to go. ''Why, Joe, I'm ashamed of you.'' "Ashamed, Billie! Why are you ashamed of me!" "Well, Joe, if I had had a father as good as yours has been [Billie had never known his father] and in his old age he asked me to come home and help him, I'd go." That decided it. ' ' I think you are right, Billie. I 'm going. " " Well, I want to see you smile then." "All right, Billie, I'll go, and I'll smile too," replied the boy, and his heart grew light again as he began to turn his thoughts toward home once more, and the simple but satisfying joys of the homeland. The homecoming occurred just before Christmas time of the year 1889. It was a very joyous home- coming. The kind and rejoiced old father, the old mother happy to see her son, and the things made dear by old association, all these conspired to make full the cup of joy; and beside near by lived the sweetheart. So the boy was very happy for some days. After that he began to explore again the old farm. It was a good farm, of 196 acres, mostly 18 ALFALFA FARMING IN AMERICA. meadow and pasture laud, with a fiue bit of wood- laud, aud about 50 acres part of the time under the plow. It was farmed in the old-fashioned way — com followed by wheat aud wheat by clover and timothy. Hogs were kept and cattle; timothy hay was sold with wheat, pigs, fat steers, potatoes, parsnips, pears, grapes and a few minor items. The father was a careful man, economical to a degree, hard working and patient. He loved his land and cared for it as best he could, saving every scrap of manure aud tilling the soil with diligence. He loved his animals and fed them well. His driving mare was almost too wide to get between the shafts; his cattle knew him and would stand to be rubbed and petted. It was through no lack of industry or in- telligence that the father had not of late years made the farm pay ; it was due mainly to his following an unprofitable system of farming. When the boy came home there was an old lame negro man helping do the farm work, old ^^ Uncle Sam'' they called him, a faithful old soul but slow and feeble. In the feedlot were about eight steers, maybe twenty pigs were being fattened, in the crib probably 500 bushels of corn, in the mows maybe 50 tons of hay. The boy took it all in very rapidly and a great hunger for the old ranch came over him, a hunger and a longing for its wide free life and its endless range of activities. To add to his unrest a letter followed him, a letter from the manager. It read like this: ^'Oome back, Joe, as soon as you can. Your place is awaiting you, and more wages if INTRODUCTION. 19 you think best, and we will build the house for your sweetheart, and you shall be your own boss. Come back as soon as you have your visit out. ' ' Small wonder then that the boy soon began seek- ing to frame some explanation or excuse to offer the father, some way to tell him that he could not stay to care for the little farm, with the great ranch calling him. And the father could read the boy's mind like an open book, so one morning after family prayers he said: ^'My boy, I wish to talk business with you. I suppose you did great things in the West. You probably had 2,000 cattle there, if you say you did. I don't know, as I never saw that many cattle together and never expect to; but I wish to show you that this old farm is not played out either. Now see here, here is what we have done this year. ' ' Then he took down from the shelf his old account book and read off the items, all duly set down in black and white, the wheat that he had sold, and the hay, the pigs and the potatoes and the cattle. And together they carefully footed it all up. It amounted altogether to a little less than $800. Eight hun- dred dollars ! It came over the boy the good salary that he had forsaken in the "West and all the bright hopes of that golden land and his heart went down like lead. *^What," he said to himself, ''have I given up all my bright prospects, all my plans and aspirations to come back and manage a farm that does not produce more than $800 a year? Why, with such an income as that, with taxes to be paid and repairs to 'be made and all expenses to be metj 20 ALFALFA FARMING IN AMERICA. 1 can not so mucli as keep old Uncle Sam. I must myself get out with tlie lantern before breakfast and feed and curry the horses and begin over again to do all that drudgery that I had only lately escaped. ' ' It was not a very worthy thought, but it added to his perplexity. The old father waited anxiously for the boy's de- cision. Very gently he said: ^'My boy. when you were with me we made more money than this. The farm then was in better condition and times were not so hard. I am too old now to develop it as it should be developed and I am tired. My happiest memories are of the time when I was strong enough to be called a man, and you were my boy, helping me. Now I am tired of being the man ; I wish you to be the man. Won't you be the man, let me be the boy and help you!" There was silence for a little time while many thoughts passed rapidly through the boy's mind, then he came to decision. ^'Yes, father, I'll stay. I'll take hold of the old farm and do what I can with it. I think we can make it profit- able after a time, and you may help me." *'Grood," the old man exclaimed. ^'Now you go ahead and do whatever you wish to do. I'll give you chance to do it, for I'll feed the cattle and the pigs. I can feed them better than any man you can hire, and you know it." ''Of course you can," replied the boy. Then : ' ' Father, let 's go and take a walk. ' ' ''All right; where shall we go?" "Oh, anywhere; just out to look at the farm again." Together they sallied out, the father happy as a child, the son glad INTRODUCTION. 21 that it was settled, the uncertainty over, yet uneasy, feeling within him a rising tide of restlessness, an aching to get to work somewhere. They did not walk very far. Just beyond the barn was a field of flat clay land, wet, mostly poor and unprofitable. All over the field rose little clay chimneys, the work of crayfish. The boy stopped here. '' Father, may I drain this field!" "Yes; it ought to have been done years ago," was the reply full of hearty encouragement. The boy went to the village and came home with a ditching spade with a blade 18 inches long. He stretched a line where the first ditch was to be laid and began digging a long narrow ditch in which to lay tiles. How happy he was all at once! Those ranch muscles of his were in good training; mightily he dug. And as he be- gan pushing his muscles against that soil he began to believe in it, to have faith in it. And after he got down in the ditch and had rubbed the mud on him well he forgot the old ranch. When at last the ditch was dug and the tiles laid and covered there was one strip of land dry, only a beginning, true, but it was a beginning. The boy stood there that afternoon as he finished covering the tile and leaned on his spade and dreamed, and talked aloud to the old field. "Old field," he said, "some day I will make you all dry. Some day, old field, I will make your soil rich. Some day I will cover you over with clover, and with corn, and with alfalfa too. Some day, old field, out of you shall sprout and grow a home, a home for that sweetheart of mine." And 'M ALFALFA FARMING IN AMERICA. he looked at his watch; it was past 5 o'clock, so he went home and shed off his muddy overalls and went across the fields to see the sweetheart, happier than any king. Spring came in all its maze of bewildering hope and promise and beauty, as it comes in central Ohio, and the boy was supremely happy. There was just the joy of seeing God's miracles all around him, the bursting buds, the unfolding leaves, the blossoms on every twig, the tender grass hiding the dull, ugly earth, the dewdrops sparkling in the morning light and all the little birds singing cheerily their songs of gratitude and joy. There seemed something prophetic in it all, and something very wonderful, Grod's forgiveness-, Grod's fulfillment of His gra- cious promises. In a dim way the boy understood and believed, and realized his own duty in the mat- ter and bent eagerly to the task, seeking in a way to make himself partner with the Almighty to cover over the few acres entrusted to his charge with grow- ing things, with bloom and with beauty. Yes, it was the joyous seedtime when all one's hopes spring up anew and he has prophetic insight into what may be and what should be, not only of the good green earth, but of one's own soul as well. Every morning bright and early the boy was astir in the fields, with a faithful colored man, Frank, to help him. He had brought with him from Utah two bags of alfalfa seed and this he wished to sow. But the father was much alarmed. ''No, my boy, we cannot afford to sow so much as that at one time. It INTRODUCTION. 23 has not been tried yet. You may have that potato patch down by the old orchard; that is good soil. Begin there and if that succeeds we will sow more later on." The potato patch had in it one-third of an acre. That was quite a coming down from his expectations, but he acquiesced and sowed the little field. Fortunately it was a good place to begin. The land was a strong clay loam, fairly well drained. It was full of carbonate of lime, for all through it were little pebbles of limestone. It was rich, for the cattle had stood there much when it was a part of the orchard. In some way or another it had become inoculated with alfalfa bacteria, perhaps because the father had grown sweet clover on the farm for years in odd corners and in his dooryard. So this alfalfa started out vigorously and grew well. The boy was delighted. He had a path well trodden where he had walked to see his first field. It settled in his mind the question of whether alfalfa would grow; he had no doubt whatever now that it would grow. Eapidly his mind went on ahead to the time when he would have 40, maybe 100 acres in alfalfa. The farm at that time had in it only about 50 or 60 acres of land that could be plowed. The rest was wet or poor or covered with trees. That summer came another boy from the old ranch, Willis. He was a wiry, slender lad, just out of his high school, and had spent about a year at ranching, getting health and strength there prepara- tory to going further with his education. He did not then dream of becoming a faxmer, yet he was. 24 ALFALFA FARMING IN AMERICA. as enthusiastic as the older brother over the beauty and promise of the little alfalfa field. He took off his coat and helped with the farm work and enjoyed it hugely till September came, when he went away to school again. It happened that he never finished his education in school; the confinement of the schoolroom was too much for his health, so fortu- nately for the farm he came back a few years later to be a partner, and later to have almost entire man- agement of the farm. Willis dreams dreams of his own and makes them come true, and he loyally car- ries out the plans of the writer. Woodland Farm owes its final development very largely to the en- ergy and executive ability of this younger brother Willis. And there was another brother yet, a sturdy lad, Charles, growing up at home; he grew to be the largest and strongest of them all and mightily he bent his muscle to help with the work. Later he too spent years in the West, ranching with sheep and cattle, and harvesting alfalfa hay there. Then he also came home and found on Woodland Farm ample scope for all his energies. It is true, is it not, that any work is as big as the man who undertakes that work? That first summer was uneventful save in the fact that the alfalfa grew so well on the trial patch. It was a year of drouth and the corn crop was nearly ruined, only about 500 bushels in all being harvested. The chief events were the long and delighttul drives that the boy took with his sweetheart and the fre- quent walks he took to watch his alfalfa. When INTRODUCTION. 25 fall came the sweetheart and the boy drove out one day along quiet byways and gathered a buggy load of wild flowers and vines and with these decorated the sweetheart's home, and that night they were married. Next day they went on a honeymoon jour- ney, with the same old horse and buggy, out again into the country, driving slow beneath the old oaks that overarched the road, and more than ever the boy resolved that his life should not be a failure; that in some way he would strive mightily to be worthy of her, who had been an inspiration to him since she was a merry child of eleven, with sunny curls hanging down on her shoulders. And as soon as they were married he began digging for the foun- dations of a little cottage in the corner of the wood- land, a cottage where she might be mistress. All winter whenever it was warm enough he worked on the cottage, so that it was done nearly altogether by the labor of his own hands saving that the sweet- heart's father came to help now and then. In June they moved in. All was fresh and new and clean, the whole air was full of hope and life was very joyous then. That spring they sowed another field to alfalfa, this time a little field of about 3 acres. And this field taught a much needed lesson. It began down by the creek where the land was low and wet, ran on up over a little hill where the land was dry and filled with limestone gravel, extended on back over some flat cold poor clay. And on only one acre of the three did the alfalfa thrive; that acre lay on 26 ALFALFA FARMING IN AMERICA. the rich dry bill, full of limestone pebbles. Down by the stream the alfalfa was weak, sickly, soon taken by the crowding grasses and weeds. Back on the flat wet poor clay it amounted to very little. On the dry rich soil full of carbonate of lime it thrived beautifully. So there the boy stood and pondered; the lesson was plain, though unwelcome. ^ ' It is evi- dent that this farm is not ready for alfalfa," he said. ^^I'll make it ready. I'll drain the wet land. I'll enrich the poor land. I'll grow alfalfa; some day I'll have 40 acres of it, but not so soon as I thought I would." So then began the work of lay- ing tile underdrains in earnest. The father had laid many in his day, but not nearly enough, judging by the new standard that alfalfa set up. And that fall the kind old father died, died in a peaceful and happy sort of way, as almost anyone would be glad to die. He had been fairly well that summer, and had insisted in helping in the hay field, raking with the horse rake and cheerily, almost glee- fully, showing the men that he was by no means worn out. One morning he arose early, as was his habit, and went out to work in his garden before the breakfast time, and there the boy had his last talk with the old man, and arranged with him about going to the fair soon to come off. After breakfast the father went to the barn and hitched his gentle mare Daisy to a spring wagon and got ready to go to the village on some errand, probably to take some vegetables to market. When the horse stopped at the front gate, coming from the barn, no one seemed INTRODUCTION. 27 with her, and when the women of the house went out to see they found the old man lying in the wagon as though peacefully sleeping, with a half smile on his lips, dead. It was a fitting end. He had lived a strenuous life, he had been good, he had been kind; he had been builder not destroyer, and wherever his foot had been put down there rich grasses and clovers had sprung up. The writer makes no pretense of being as good or careful a farmer as his father was. We try to fol- low in his footsteps, that is all, and we do things in a larger way than he in his old age cared to do them. Yes, the father was gone, and with him the safe counselor, and the boy all at once realized how much he had depended upon this counsel. He could do as he pleased now, but he was not glad of the chance. He would have been very glad indeed if he could have had the continued company of the old father. He took account of stock. The farm was not pay- ing; the crops that grew upon it when all sold could not possibly bring money enough to make it a busi- ness worth while. Much of the land was too poor to be profitable. The little alfalfa fields paid well, but they were but small spaces after all ; the rest of the farm was mostly unfit for alfalfa. The farm needed enriching, needed further drainage. H ever it paid it must be made rich. How! Well, there was stable manure. The boy knew about that; the old father had been a most careful user of manure ; he saved all that he could, but he fed his cattle out in the woods where the manure was largely wasted. 28 ALFALT^A FARMING IN AMERICA. The boy reasoned: ''Our practices are wrong. We sell off timothy hay and wheats and thus load by load we sell away the fertiUty of the farm, and>vhat we do feed is largely wasted, as we do not get the manure. Now if ever we build this farm up we must feed on the land the crops that we grow upon the land. And if we make any money in feeding animals we must feed younger animals than we have been feeding. We must feed some sort of babies. Now what shall it be?'' Then he thought of the lamb. ''Why, here is the lamb/' he said. "He is a baby, a gentle little fellow. One can put him in the barn, can feed him there in shelter. His manure will all be saved in good order and can go direct to the fields with no wastage, and from the feed given him one ought to make good gain and thus make money." He had already a little flock of ewes which were his pets and his darlings. To them he added now a little bunch of 200 feeding lambs, building a shed to hold them. As he had no money only what he borrowed, he bought the small- est and cheapest lambs that he could find. They were natives, fairly healthy, and weighed 55 lbs. when he put them in the sheds in November.. He had carefully dipped them in a half barrel, and had himself as thoroughly dipped as the lambs, so they were free from ticks. All winter he fed them care- fully, every feed with his own hands. Not knowing anything about feeding lambs, he had written to Prof. E. W. Stewart to get his advice as to how they ought to be fed, and he had told him how to INTRODUCTION. 29 compound a ration with wheat bran, oilmeal, corn and mixed timothy and clover hay. He had too httle alfalfa hay yet to make much show in the feeding barn. The lambs throve; they became very fat in- deed and in May weighed 108 J lbs. In fact in all the years that lambs have been fed on Woodland Farm no such gain has since been secured, which simply shows that a greenhorn may do as well as an expert, if he has his heart in it and is earnest and careful. The boy had kept careful account of what the lambs had eaten so he knew what the gain had cost him. When he had figured it all up he found that he had made a clear profit from feeding these lambs of $115, the first real profit from Woodland Farm since his new venture in manage- ment. It was a small sum, yet mightily it encour- aged him. And then he dreamed another dream, out there on the sunny side of the barn. Thinking it over, he said: ^'Some day we'll feed a thousand lambs on this farm.'' But he told no one that, not even his wife, for all would have smiled in derision, for had he not bought part of the hay that he had fed this first 200? But there was more manure to haul out than ever before, and it was put where corn would be grown and where alfalfa might be expected to succeed, and more alfalfa was sown. Wherever the manure had been put out and the drains laid the alfalfa suc- ceeded. Inoculation took care of itself on Woodland Farm after the first start, because of the use of manure made from alfalfa hay perhaps, and every BO ALFALFA FARMING IN AMERICA. little field added to those first started succeeded in almost direct proportion to the amount of manure used and the thoroughness of the under drainage. The next winter 300 lambs were fed, then 350, then 350 again, and then a larger barn was built and 700 were fed. The work grew easier and easier ; wheat was dropped from the rotation, and no more timothy seed was sown. Lamb feeding promised profit, so finally it was resolved that lambs would be fed and crops grown that lambs liked, and nothing else. Meanwhile Willis and the writer bent their backs energetically in the ditches, draining more and more land, and hiring men to dig what they could not. Charlie, too, growing up a stalwart boy, helped cheerfully, and the three brothers were full of faith. And yet neighbors smiled, and some there were to sneer. It is true that when the new barn was built with a mow that could hold 100 tons of hay men asked smilingly if we thought we could borrow money enough to buy hay enough to fill it, and went off laughing when we declared that we would fill it from our own alfalfa meadows some day. No one else in the country was trying to grow alfalfa, so far as we knew, no one else in Ohio, though there was some grown in Onondaga Co., New York. Well, we filled the barn at last, and had an overflow. We fed a thousand lambs as we had dreamed, and we fed 1,200. We had learned how at last. Lamb feed- ing is an art, a science ; it is not yet all learned. It had not all been smooth sailing, this lamb feed- ing. More than one disaster had overtaken us. INTRODUCTION. 31 There had been bad years, low prices, diseased lambs, all sorts of troubles. Grimly we had held on. ' ' We can 't afford to change now, ' ' we declared. ' ' We have made too many mistakes in what we are doing. To change now would be to lose all we have gained by making these mistakes; we don't have to make the same mistakes the second time." So we held on, confident that our scheme was a safe and reason- able one, based on alfalfa growing, the alfalfa fed to lambs, the manure put out for corn, the well en- riched corn stubble sown to alfalfa, often with addi- tional phosphorus and as much as possible of the corn and alfalfa fed back to lambs again. But during these years we were in debt, a little at first, but steadily the debt grew. We owed for labor to dig drains, we owed for labor and materials to build fences and barns. We did all the labor that we could do with our own hands, but we were too im- patient to wait to develop the place ourselves. ^'Farming either is or is not a business proposi- tion," we declared. ^' If it is a safe business propo- sition this thing will pay some day, and if it is not we will break and be done with it. If we can 't farm as a business proposition we prefer to break up trying it." And ever and often the writer, the older of the brothers, declared to Willis, his willing lieutenant: ^^It is only a question of one good year, just one good year, and the lambs will pay every dollar that we owe and we will have the ditches laid, the buildings built, the fields made fertile, and it will all be ours." S2 ALFALFA FARMING IN AMERICA. That year came when we had 1,200 lambs. We had learned how to feed them by this time, and they were as alike as peas, and ripe and fine as they could be. The commission merchants down in Buf- falo had learned to watch for our lambs and to prize them. They had an alfalfa quality about them that Qo one could attain except he had alfalfa. We had fed them this winter altogether on alfalfa hay and ear corn, all grown at home, and we had hay left over enough to sell to our neighbors ; some of whom needed hay with which to do their spring plowing. Well, we sold the lambs, one load at a time, and the checks came back and we laid them down on the bankers ^ counter. Now we owed no one in the world but this bank, but we owed it a lot of money. Stead- ily despite the fact that we had economized, had rid- den in our old buggies and worn our old clothes, this debt had grown, and at last it had become a serious burden on our minds ; it seemed' incredible that it would ever be paid. At last the last check had come. With a fast beat- ing heart the writer laid it down on the bankers' counter. ^'Here it is. The lambs are all sold; is it enough to pay that noteT' The banker smiled; he was a good fellow. ''Yes, plenty to pay it, and some over," and he handed the note through the window, cancelled. The writer looked at it; how huge then the amount of it seemed ! He tore off the signature and turned anxiously again. '^Tell me," he asked, ''how much is there left!" The banker ftifured for a moment and presented with a smiling INTRODUCTION. 33 face the bank book, where on the right side of the page was a credit balance of $800. The debt was paid. The tiles were laid, or a lot of them were laid at any rate, the barns were built, the home was paid for and there was actually money in the bank! The writer feels that there are many happy days ahead of him, but never again expects to experience the relief, the thankfulness, the joy that came to him when his first victory was won for Woodland Farm, and the brothers fully shared the feeling. The writer jumped into his old buggy and drove home, his face wreathed in smiles and his heart singing a joyous song. As he neared his home tlie thought came: ^^Why, I will have some fun with the sweetheart. I will make believe the thing has ended badly. I will tell her some sort of story to deceive her, just at first ; afterward I will undeceive her.'' But when he drew near the little cottage she stood there in the open door waiting for him to come, looking out at him, all unconscious, yet on her face was revealed all that the thing meant to her, and his heart became suddenly very tender and it came over him with a shock of understanding. ' ' Why, I never dreamed that the girl cared like this. Did she per- haps wonder whether the home would be sold, the place where she had planted flowers and vines, the place where her babies were born? Where she had been so brave, so strong, so patient and helpful all these years, and yet cared so much as this!" So all his foolish stories were put aside and he told her the glad truth. 34 ALFALFA FARMING IN AMERICA. And what had the farm done that year! After all the items of sales and expenditure were footed up it was found that the same land that had yielded our father less than $800 had yielded us a net profit of more than $2,500. Alfalfa had worked this miracle. It had given us the hay with which to feed the larger number of lambs, and through the soil enrichment that it had given the fields it had made possible the heavy crop of corn that we had fed to the lambs, so really to alfalfa should be credited both corn and hay. Further, alfalfa had made it possible to con- tinue feeding lambs. When we were beginning, and were almost without alfalfa hay, we had fed largely of oilmeal and wheat bran to balance up the ration. This was necessary; experiment proved that. With- out plenty of digestible protein in the ration the lamb does not gain much. We made good lambs through the aid of the bran and oilmeal, but it cost us too much. When finally we had our own alfalfa hay to furnish protein we made two lots of lambs. They had equal merit in the beginning as near as we could tell, for they were of the same bunch, se- lected to get two like lots. The one pen was fed with timothy hay, with some clover, shredded corn fod- der, corn, wheat bran and a little oilmeal. They grew well, but each pound of gain made cost us Gi/oC. The second lot was fed with good alfalfa hay and corn only. With them the cost of gain was only S^c. As the price of lambs declined during the nineties we would have had to give up had not al- falfa come to our rescue. INTRODUCTION. 35 At the present writing (1909) we are feeding some 1,450 lambs, with about 150 ewes and lambs, and we could as readily feed 2,000 or more if we had more shelter for them. Woodland Farm is larger now; the alfalfa has crowded the line fences back a little. It contains 320 acres and is devoted mainly to the growing of corn and alfalfa. During the summer of 1908 corn was grown on 90 acres of alfalfa sod. This field had been twice sown to alfalfa, with intervals when it was planted in corn. The last pe- riod of alfalfa was a 6 year period for part of the land and a longer period for the remain- der. During the 6 years there were taken off at least 20 crops of hay, certainly 20 tons of hay to each acre. During this time no manure was put on the field, but on parts of it phosphorus was applied in the shape of acid phosphate, about 300 lbs. per acre or maybe a little more. The great crops of hay taken continually off of this field disturbed our mother, who finally spoke in sorrowing tones to the writer, thus : ^^ Joey, I am worrying about that alfalfa field.'' *^Why, mother?" ^^ Because you do not manure it. You haul off hay and haul oif more hay and it seems to me you actually have hollowed the land out so that it is lower than it used to be. I think of what your father would say if he could see it. Why don't you put some manure on it, boy!" I assured her that I could not believe that the land was really getting poor, and that we were putting the manure out carefully on land that we knew was 36 ALFALFA FARMING IN AMERICA. poor, and she said no more. When we plowed the land in the winter of 1908-09 it seemed more mellow and friable than usual, so we plowed it deeper than it had usually been plowed. And when we disked it up in the spring it was most evident that the field had changed its character somewhat, so loose, mellow and friable it seemed. We resolved to make an ef- fort to beat our record for corn raising, so we planted with care. The seed was good and had been tested. We got nearly a perfect stand over much of the field and all summer gave it good culture. There was a most serious drouth late in the summer, which doubtless cut down our yield somewhat. Yet 50 acres of that field made for us a little more than 100 bushels of shelled corn per acre and the entire 90 acres only fell a little short of making 9,000 bushels. This result astonished us, as the field had in olden times yielded only about half that amount. In truth the alfalfa had built it up far beyond the fertility that it had had when a ^'virgin soil.'' Let us briefly examine this miracle and see how it was accomplished. In the first place it is probable that this especial field has in it already about as much potash as it needs for large crop production, since it is a glaciated soil. Most of the field is well supplied with lime ; in truth one can find small peb- bles of limestone sticking all through the soil. Thus it was sweet, and the alfalfa revels in sweet soil, al- kaline, not acid. So the alfalfa was at home there. Then the land had been thoroughly well under- drained; thus it was full of air. Alfalfa bacteria INTRODUCTION. 87 thrive in soils rich in lime and full of air ; they perish in a wet sour soil. Thus the alfalfa filled all the soil with its rootlets, going down often as far as 6 feet, no doubt, and numberless millions of bacteria work- ing there were storing the soil with nitrogen drawn from the air. The phosphorus supply may have been somewhat deficient; we bought phosphorus for part of the land and added that. Then the land was plowed; the plow cut off millions of those big roots and left the top soil one mass of roots, with also many little rootlets and many leaves and stems that had fallen down. And the subsoil was made porous by being honeycomhed by millions of the tap roots, so the )air penetrated all the more easily. Thus it is seen that conditions for a big corn crop were almost ideal. It would be an interesting thing to know just how much richer Woodland Farm is than it was before alfalfa began to grow upon it. It is safe to say that the alfalfa, yielding on the average 300 tons of hay per year for the past ten years, has added to the soil plant food worth at least $3,000 each year, count- ing the manure that has been returned and the work of the roots; probably this is an underestimate, in fact. Once we racked our brains to find manure enough, and never did find enough. Now we rack our brains again to find time to haul out the manure that is made upon the farm. Gathering fertility by the use of alfalfa is like rolling a snowball — ^the farther you roll it the faster it gathers. This would not be true if the hay was sold off of the farm, but 38 ALFALFA FARMING IN AMERICA. it is certainly true when the hay is fed and the manure carefully saved and returned, to make an- other spot rich for alfalfa to grow upon. The story of Woodland Farm is only half told; the rest lies in the future. We have some acres that yield as much as 6 tons of hay each year, yet the average of the whole farm is less than 4 tons. Thus we are not yet inclined to boast of our success with alfalfa. We now are proceeding to try to spread these good yielding areas. What is the secret of the lands yielding alfalfa so well? Perhaps we do not know the w'hole story, but here is what we can readily observe. One of these spots is a round hillock. It is a strong, tough, tenacious limestone clay. Stick- ing all through that clay are bits of limestone peb- bles, as large as grains of corn, as large as a man's foot, and of all sizes. These pebbles are of soft mag- nesian limestone. They readily decay and keep the land very sweet. Alfalfa roots seem to like actually to touch carbonate of lime. On that hillock the al- falfa never gets old. It is one of the most productive spots on the farm. On it our father put much ma- nure, for it was, when he bought the farm, extremely unproductive. We have not manured here for many years. On other lands we find the limestone pebbles all dissolved away in the surface soil. When we dig down two feet we find them in abundance, but on the surface there are none. Here we are assuming that lime is needed, and are putting on more car- bonate of lime, buying ground and unburned lime- INTRODUCTION. 39 stone and applying it at the rate of about 5 tons to the acre. Probably that is too little ; it is yet too early to know. We feel sure that when we have made the drainage right and the lime content right we will grow as much alfalfa over all the farm as we now grow on those favored spots. Then we can proudly boast, sure enough! Then we can say: *^From 100 acres of land we harvested 500 tons of alfalfa hay.'' It may take time to reach this con- dition. It may not even come in my day. But we have boys and to these boys we bequeath the ideal, the task, and to them will fall the pleasant duty of spreading these spots of gloriously beautiful alfalfa, rich and productive beyond anything else that could be sown. It may be of interest to know something of the present system of farming on Woodland Farm. Let us begin with the alfalfa sod that is to die that corn may live. It is plowed usually in November and during the winter. Perhaps the field was mown off late, four cuttings being taken from it, in antici- pation of its impending destruction. We find that late cutting is bad for the alfalfa and do not usually cut it later than early in September. This field to be devoted to corn then will be mown off late, as it does not matter how much the roots are weakened. Usually we plow with very strongly built walking plows. We put two wheels on the beam, well in front ; one wheel runs in the furrow, the other on the unplowed land. These wheels hold the beam rigidly in place, and thus the plow runs well ; a boy can man- 40 ALFALFA FARMING IN AMERICA. age it if the thing is set right. We keep the plows sharp. The plowman carries a file and often lifts the plow out of the ground and sharpens it well. The land is plowed deep, from 7 to 10^', and we hope ultimately to plow much deeper than that. We aim to get the land all broken before mid-winter, so that the frosts may work on it. No manure is used on alfalfa sod. It is disked and fitted for corn which is planted usually about May 5 in checks. This corn is as well cultivated as we know. Often in the early part of the season the alfalfa roots will grow, espe- cially if the season is wet, and the field will look not a little green. This does not disturb us in the least, for after the corn cultivation begins the alfalfa soon weakens and mostly disappears. Some stray plants will escape destruction and will live over, even for two or three years of corn. This is all the better, since thus the inoculation is safely carried over. The corn has as clean cultivation as we can give. We discourage weed seeding as much as pos- sible. We have learned that that enemy of alfalfa, fox-tail or pigeon grass, can be surely eradicated in one year by not letting a stalk of it make seed. The corn is cut and shocked. Before winter it is husked and the folder set up, two shocks in a place. We cut our corn 12 hills square ; at present our hills are 42'' apart. We find corn to thrive wonderfully on alfalfa sod. The second year will usually find this land yet in corn. This time as much manure from the stables and sheep barns as can be found will be put on. Even with this manuring INTRODUCTION. 41 we do not expect quite so good corn as we had when we grew it on alfalfa sod. As before^ clean cultivation is given. We are especially careful to destroy all fox-tail grass before it seeds. This land is now to be sown to alfalfa. If it needs lime that is applied as convenience suggests, when- ever the teams are idle and the land is hard enough to drive on. We use finely ground raw limestone rock, not burned. We use about 4 tons ^to the acre of this. It cost us only $1.25 per ton on cars. The land is plowed as deep as the plows will run, making the furrows narrow. We would plow 24'^ deep if we could do so. Some day no doubt we will begin sub- soil work, and expect that to pay well. We like to do this plowing a month or more before time to seed alfalfa, so that the earth may settle well together again. In April we disk and prepare the land with some care, but not attempting to make any ^^ash heap^' or ^'onion bed,'^ as some advise, only a little better seedbed than one would make for corn. About April 10 we begin drilling. AVe use a fertil- izer drill that sows fertilizer, beardless spring barley and alfalfa seed. Of barley we sow 2 bushels to the acre; of alfalfa seed, 15 to 20 lbs.; of fertilizer (usually plain acid phosphate, sometimes bone meal) we use 300 to 500 lbs. per acre. We think it prob- able that the more we enrich the land the greater our profit is. We let the alfalfa seed fall in front of the drill sometimes, at other times behind the drill, ac- cording to the condition of the soil. If moist we do not roll but follow the drill with a plank drag. If 42 ALFALFA FARMING IN AMERICA. the land is dry and cloddy we use a roller to com- pact it and to leave the surface smooth so that the mower may run over it readily. We do not inocu- late, since all the farm is now filled with alfalfa bac- teria. The alfalfa comes up with the barley and all grow together till the barley has come into head; before grain has formed in the heads it is mown off and all made into hay. Barley hay is exceedingly good hay, though not so good as alfalfa hay, of course. After this cutting the alfalfa comes on rap- idly and in about 45 days, or a little less, it also is cut and a crop of hay taken off. We judge of the time to cut this young alfalfa al- together by the condition of the growth, not by the bloom. When small shoots appear at the base of the stems, down by the ground, as though it was ready to make a new growth, then it is to be cut, and not before that time. If cut before these shoots or buds appear, the alfalfa is very greatly weakened and sometimes is destroyed. After this cutting the alfal- fa is left religiously alone; it is never pastured nor mown nor tramped in any way during the fall or win- ter. The fall growth of about a foot or a little more is worth a very great deal to the plant, in some way or another ; it helps hold the snow and makes it win- ter better. The next year the alfalfa shoots out as soon as the frost is out of the earth. Alfalfa fields are sacred ground on Woodland Farm, and never unless by accident is an animal per- mitted to tread upon them. It is especially im- portant that no stock go upon them in the spring INTRODUCTION. 43 when tiie young alfalfa is pushing up ; even though the alfalfa might be destined for pasture everything is kept off until it has made good growth, and is nearly knee high and almost come into bloom before stock is turned in. Gloriously beautiful the fields be- come in May, and as June draws near we watch them to see how nearly they are approaching harvest. We have long ago learned not to regard the bloom- ing of the alfalfa as 'being an essential indication of maturity, but only we suspect that it is ready for cutting. We get down upon our knees in the field, and parting the stems look to see whether small buds have appeared at the surface of the ground. If these buds or shoots are pushing out, showing that the plant is ready to make new growth, then the mowers come out, three of them, each cutting swaths 6' wide, and with merry rattle the beautiful green forage is laid low. Not much use is made of the tedder on Woodland Farm, since it shatters off the leaves too much, al- though sometimes it is employed when the crop is very succulent and heavy. Before the alfalfa is dry enough for the leaves to shed off, the rake is started and the hay gathered into small windrows, which are then piled into slender but fairly tall cocks by the use of the hand fork in the old-fashioned way. Eather a jolly time haymaking is, with all the men and boys on the place busy in the field, with merry callings to and fro and sometimes the note of a song, yet it is a busy place too. Seldom can the hay be drawn in the same day as it is cut down, and not al- 44 ALFALFA FAEMING IN AMERICA. ways on the next day^ but as soon as it is dried it is placed on broad; low-platform wagons, each bed 16' long and 7' wide, with tight board floors; and taken to the barn where it is unloaded by horse forks. The farm possesses 7 of these wagons, so that each even- ing it is the daily duty to load up the 7 wagons with from 10 to 14 tons of hay, which are then drawn un- der shed ready to be unloaded in the morning. Not much is doing in the alfalfa meadows in the fore- noon; then is the time chosen for work in the corn fields, and cultivators are pushed steadily. These two crops, corn and alfalfa, constitute almost all that is grown on Woodland Farm, excepting a few acres of soy beans and the blue grass pastures, but as the alfalfa is cut three times during the season, and the corn cultivated at least five times, there is no dif- ficulty in keeping everyone busy. The writer makes no apology for having devoted so much time to the operations on Woodland Farm, since he feels that in a sense this is a pioneer farm, and fairly prophetic only, of what will be very com- mon throughout all the region of the corn belt. Very certainly these two crops, corn and alfalfa, are by far the most profitable of any, and do most conserve the fertility of the soil, do best nourish all manner of farm animals, do most surely build the fortunes of the farmer. Deeply buried in the soil of the fields, the alfalfa roots know nothing of the vicissitudes of winter; as certainly they put out green as leaves up- on the oaks in spring, and drouths that wither up ordinary meadows have little effect upon them. mTRODUCTION. 45 Wheat, oats, potatoes, timothy grass and a hnndred other things are uncertain, affected vastly by the vicissitudes of the weather. Alfalfa once rooted in dry rich soil has the permanence of the wild native things. Corn also planted upon alfalfa sod well cul- tivated mocks at seasons, for floods affect it not, since the land must perforce be well drained, and drouths and heats that sear other vegetation pass it by, leaving it fresh, green and undismayed. These two crops then are destined not to free the farmer from labor, for they bring abundant labor to him, but to take away from him the cares and perplexi- ties incident to the growing of uncertain things. HISTORY. The world is very old. For more ages than we dream men have lived and loved, toiled, sown and reaped. The history of the race is written in the form, variation and characteristics of animals and plants much more than in tablets of stone or pieces of clay. Would you ask how long men have lived on earth! Ask when first hornless cattle were kept. Records in Egypt show them to have been common thousands of years before the time of Christ. Ask when sheep were first tamed and their fleeces developed. The very race of wild sheep has per- ished from the face of the earth and the sheep of Abraham's day were highly developed. Ask when wheat was taken from being a wild grass and made a cultivated plant; when the banana ceased to have seeds; the apple gathered sweetness and the vine began to hang down with luscious clusters of pur- pling grapes. Ask, too, when it was that animals became the subjects and friends of men; when men began to feed them, to gather forage for them, to cultivate plants for them, to perceive which plants were the best plants and which best fed the animals. Ask, too, when men first saw that soils grew worn, that certain plants fed soils, that other plants caused them to become infertile. (46) HISTORY. 47 All these things happened many thousands of years ago. The best things done by men are older than recorded history. The taming of the ass, the taming of the horse, the taming of the cow, the devel- opment of the milk-giving powers of the cow, the caring for sheep and goats, the breeding of sheep for wool, the spinning of wool and flax, the melting of ores — all these primal things happened long centuries ago. Since historic times man has learned very little indeed that iie needed to know; the important, primal, essential things were all worked out before men began to write upon stone and upon parchment. It is not certain that there exists today any wild al- falfa. There are places where some has escaped from cultivation and gone wild, but all alfalfa, so far as known, has so changed its form from what it would be in the wild state that it is doubtless bearing in its nature the very marked signs of the moulding hand of man. For example, all alfalfa so far as known today needs to be cut off from time to time to keep it in thrift. No wild plant requires that. Alfalfa that we know reflects a long line of civilizations, re- flects the habits of people who have kept cows and donkeys and sheep and horses, kept these and fed them, carrying their forage to them on men's backs for ages untold. It requires no effort of the imag- ination when looking out upon an alfalfa field to picture the fields from which it sprung through the ages past. The little fields fair and green and fertile under hot glowing desert skies mostly. Little fields 48 alfaLtFa farming in America. for the most part walled often with walls of stone or of snn-dried bricks, lined with little canals of cool water with overhanging trees, fig trees or al- monds or palms, and brown men and women, lithe and strong, coming to cut the green meadow with curved sickles and scythes, gathering it in sheaves and carrying it on their backs through gates in the walls to the animals eagerly awaiting it in the en- closed corrals or stables. Alfalfa was developed in dry regions. It came, very likely, from southwest- ern Asia through Persia to Arabia, whence it got its name alfalfa, which simply means the best forage. The Persians grew it finely. Down along the rivers of Babylon in ancient Babylonia alfalfa was a stand- ard crop, most likely. Those river valleys are rich in lime and alkaline in their reaction, admirably suited to alfalfa culture, and there under irrigation alfalfa undoubtedly throve. The one reference to alfalfa in the Bible is found in the fourth chapter of the book of Daniel where in the thirty-third verse it is related of the king : "The same hour was the thing fulfilled upon Nebuchadnezzar: and he was driven from men, and did eat grass [alfalfa] as oxen, and his body was wet with the dew of heaven till his hairs were grown like eagle's feathers and his nails like bird's claws. And at the end of the days, I Nebuchadnezzar lifted up mine eyes unto heaven, and mine understanding returned to me, and I blessed the Most High, and I praised and honored Him that liveth forever, whose dominion is an everlasting dominion, and His kingdom is from generation to generation." The truth probably was that old Nebuchadnezzar, rich, spoiled, feasted and wined till he became in- sane, was turned out to graze in an alfalfa field till on this simiple and nutritious diet his body was re- HISTORY. 49 newed, filled witli liealtli and vigor, when liis reason returned and of course he did what an3^ healthy man will do daily, blessed the Most High and praised Him and was humbled and glad once more. It is related that in the old kingdom of Babylonia wheat would yield 200 fold and sometimes 300 fold, which plainly indicates that it must have been sown ' thinly in drills upon alfalfa sod, irrigated from the canals with which that country abounded, and prob- ably weeded and cultivated by slave labor. About 500 years before Christ the Persians invad- ed Greece. Now, Greeks are stubborn folks, or were in those days, and many were the battles before the Greeks were even in part conquered. The Persians, aided by Greek factions and tribes, doggedly toiled steadily onward, taking city after city. Wherever they went they had chariot horses to feed and cattle — bulls, so legend says — for fighting, and cows no doubt for helping feed the army. With curious mix- ture of martial and agricultural zeal they brought with them alfalfa seed and wherever they conquered foothold they sowed alfalfa. An army travels, and fights, on its belly, so it was a mighty help to the Greeks to have the aid of the alfalfa. And without doubt it was eaten by the soldiers as well, since green succulent alfalfa has always been boiled and eaten as greens or pottage. Unhappily the Persians sent away hosts of the Greek subjects as slaves to Asia, else when they had gone on the people might have been almost benefited by the war, since alfalfa fields were left in the wake of the army. It must be 50 ALFALFA FARMING IN AMERICA. remembered that much of the land of Greece is formed from the decay of limestone and marble. Thus filled with carbonate of lime it is naturally fitted for alfalfa culture as well as for the production of such magnificent men as the Greeks undoubtedl> were. From Greece alfalfa spread into Eome, just when we do not know. The first real farm books were written in the first century after Christ. One L. Junius Moderatus Columella, born in Spain but liv- ing most of his life in Italy, wrote twelve books which he called '^De Re Rustica.'^ These books were written about the year 56 A. D. It would seem from dipping into the pages of Columella that about as much was known then of agriculture as is known today. Indeed, they knew then many things that we do not know today, and agriculture has lost many picturesque details by the pruning away little by little of agricultural fancies, by the accumulations of stern facts. But however much we may smile at some of Col- umella's account of ancient Roman agriculture, we will respect him for his account of alfalfa and the way to grow it. Many forage crops are mentioned by Columella — medic (alfalfa), vetches, bitter vetch, chick pea, barley, oats and wheat. Speaking of the various sorts of fodders he says the herb medic (alfalfa) is the choicest, because when it is sown it lasts ten years. He continues : It can bear to be cut down four times, sometimes also six times in a year, because it dungs the land. All emaciated cattle what- HISTORY. 51 soever grow fat with it because it is a remedy for sick cattle, and a jugerum of it is abundantly sufficient for three horses the whole year. It is sown as we shall hereafter direct. About the beginning of October cut up the field wherein you design to sow medic next spring and let it lie all winter to rot and grow crum- bly. Then about the first of February plow it carefully a second time and carry all the stones out of it, and break all clods. After about the month of March plow it the third time and harrow it. When you have thus manured the ground, make it in the manner of a garden, into beds and divisions ten feet broad and fifty feet long, so that it may be supplied by water with paths and there may be an open access for weeders on both sides. Then throw old dung upon it and sow in the latter end of April. Sow it in such a proportion that a cyathus of seed may take up a place 10 feet long and 5 feet broad. After you have done this, let the seeds that are thrown into the ground be presently covered with earth with wooden rakes. This is a very great advantage to them because they are very quickly burnt up with the sun. After sowing, the place ought not to be touched with an iron tool, but as I said it must be raked with wooden rakes, and weeded from time to time lest any other kind of herb destroy the feeble medic. You must cut the first crop of it somewhat later, after it has put forth some of its seeds. Afterwards you are at liberty to cut it down as tender and as young as you please after it has sprung up and to give it to horses, but at first you must give it to them more sparingly until they be accustomed to it, lest the novelty of the fodder be hurtful to them, for it blows them and creates much blood. Water it very often after you have cut it. Then after a few days when it shall begin to sprout weed out of it all plants of a different kind. When cultivated in this manner it may be cut down six times in a year and it will last ten years. That instruction bears evidence of muc'li famil- iarity with the alfalfa plant. It must not be cut too soon the first time, not till some seeds have formed. It is true here that young alfalfa is destroyed often- times if cut before the young shoots have put out at the base of the stems. Not having observed this perhaps the old alfalfa growers judged by the state of bloom or seeding when it should be cut. Note that Columella says '4t dungs the land." Thus early they knew the practice of farming with legumes, 52 ALFALFA FARMING IN AMERICA. and that alfalfa was the best of the legumes for this purpose of enriching soils. Note too that he found it a good food for horses. It is said that the chariot horses were fed on alfalfa hay, and the colts destined to become war horses were raised largely on it because it made them larger, heavier and more impetuous. From Italy alfalfa naturally spread wherever the Eoman farmer colonist penetrated, through France^ Spain, England and doubtless Germany. It may be that Spain also received alfalfa from Africa through the Moors. The name alfalfa comes from the Ara- bic and means the best forage, and this name the Spanish people adopted. Through the introduction of the plant in America by the Spanish colonists and our taking it from them on our Pacific coast we get the name alfalfa. In France, England and most other European countries, and in Utah and formerly through all our eastern states, the name lucerne is in common use. This name comes from a river val- ley in northern Italy. Alfalfa throve in Italy, in much of Spain and in parts of France. Where it throve no other forage plant could compete with it. It was introduced long ago into England and there it throve in spots. It was much extolled by some, its planting advised, yet it never became common and today is seldom seen in extensive use on the British Isles. It was brought to America in two ways, from Spain to Mexico, Peru, Chili, Argentina., from Mexico to Texas, New Mexico and California; later from Chili HISTORY. 53 to California in 1851, which marked the really im- portant step in alfalfa growing in America. The other source was the bringing of lucerne seed to the eastern states of America from England, France and Germany early in the history of Ameri- can colonization. In the eighteenth century many men were experimenting with lucerne in Virginia, New York, North Carolina and doubtless other states. Some of them succeeded quite well and many of them doubtless failed. We know now the reason why many failed. Then the behavior of lu- cerne was a mystery to the farmer. We had not learned then the intimate connection between alka- linity of soil and presence of abundant carbonate of lime and alfalfa culture. It is all very easy to ex- plain this now — how alfalfa came from alkaline soils rich in lime down in Persia, into the alkaline plains of Babylonia, to the limestone soils of Roman lands, to the soils of Greece built on marble decay, to the limestones of southern France, to the alkaline soils of semi-arid north Africa, to the soils rich in lime and alkalies in Spain, thence to similar soils, yet richer in lime, in Mexico, Chili, New Mexico and Cal- ifornia. In England soils vary immensely as regard their lime content. Some are very rich in lime ; on these lucerne throve : in others lime is very deficient ; here it failed. In France there is found a similar variability, so also there were found areas that grew good lucerne, and others that grew none at all. In eastern America, on the other hand, nearly all soils were from the first settling of the country deficient 54 ALFALFA FARMING IN AMERICA. in lime and thus unfitted for alfalfa. Yet the soils as our fathers found them were sweeter than they are today, and thus we often hear old men relate that in their boyhood their fathers grew lucerne and that their daily task was to cut it and feed it to the cows ; this on land that will not today unaided grow alfalfa at all. In reading over the written accounts of how to grow lucerne published in the last century one is amazed to find how much the authors knew of the habits of the plants, and as much astonished to per- ceive that few if any of them understood the vital connection between alfalfa and a large percentage of carbonate of lime in the soil. One of the good old books on agriculture is ^'The Dictionary of the Farm/^ by the Eev. W. L. Eham, Vicar of Wink- field, Berkshire, who died in 1843. The article on lucerne is strikingly good, so good, indeed, that had the author known two facts of which he seems to have been unaware there would have been left little to add. He evidently had not traced the relationship between thrifty lucerne and a strong lime content in the soil, nor had he seen the harm that comes to lucerne when it is mown off too early, before it has made sufficient growth to start the little shoots at the base of the stems. Ignorance of the latter fact is very universal in England at the present time and leads to much lack of thrift and falling away of the alfalfa plants that are usually cut with the scythe bit by bit, and fed to horses green, just as Eham advised. The writer has indeed pointed out to Eng- HISTORY. 55 lish farmers that the lower sides of their lucerne fields remained thrifty after the upper ends were half destroyed, just because of the fact that the man with the scythe commenced on the upper end before it was time to cut the immature plants, and by the time he had reached the bottom of the field it was sufficiently mature, so remained in vigorous condi- tion. The article follows from ''Eham's Dictionary of the Farm," published in 1853: Lucerne is a plant which will not bear extreme frost nor super- abundant moisture, and its cultivation is therefore restricted to mild climates and dry soils; but where it thrives its growth is so rapid and luxuriant that no other known plant can be compared to it. In good deep loams lucerne is the most profitable of all green crops; when properly managed the quantity of cattle which caiL be kept in good condition on an acre of lucerne during the whole season exceeds belief. It is no sooner mown than it pushes out fresh shoots, and wonderful as the growth of clover sometimes is in a field which has been lately mown, that of lucerne is far more rapid. Where a few tufts of lucerne happen to be, they will rise a foot above the surface, while the grass and clover which were mown at the same time are only a very few inches high. Lucerne, sown in a soil suited to it, will last for many years, shooting its roots downwards for nourishment till they are alto- gether out of the reach of drouth. In the driest and most sultry weather, when every blade of grass droops for want of moisture, lucerne holds up its stem, fresh and green as in a genial spring. The only enemies of this plant are a wet subsoil and a foul sur- face. The first is often incurable; the latter can be avoided by good cultivation. It is useless to sow lucerne on very poor sands or gravel or on wet clays. The best and deepest loam must be chosen, rather light than heavy but with a good portion of vegetable earth or humus equally dispersed through it. If the ground has been trenched, so much the better; and if the surface is covered with some inferior earth from the subsoil it will be no detriment to the crop, for it will prevent grass and weeds from springing up and save much weeding. The lucerne will soon strike down W 56 ALFALFA FARMING IN AMERICA. low it. It is not a bad practice to cover the lucerne field with a coat of coal ashes or poor sand, merely to keep down the weeds, where this can easily be done. The soil in which it is intended to sow lucerne seed should be well prepared. It should be highly manured for the two or three preceding crops and deeply ploughed, if not trenched. It should be perfectly clean, and for this purpose two successive crops of turnips are most effectual. The turnips should be fed off with sheep. In the month of March, the land having been ploughed flat and well harrowed, a very small quantity of barley, not above a bushel to the acre, may be sown, or rather drilled on the ground, and at the same time from 30 to 40 lbs. of lucerne seed sown broadcast and both harrowed in and lightly rolled. If the land will not bear to be laid flat without water-furrows, it will be useless to sow lucerne in it. As the crop comes up it must be carefully weeded: no expense must be spared to do this effectually, for success depends upon it. When the barley is reaped, the stubble, which will probably be strong, should be pulled up by tne hand hoe, or by harrowing, if the plants of lucerne be strong, and at all events the ground must be cleared of weeds. It must not be fed off with sheep; they would bite too near the crown. Lucerne should always be cut as soon as the flower is formed. If it is kept clear of weeds the first year, there will be little difficulty with it afterwards, when the roots have become strong. The second year the lucerne will be fit to cut very early, and in a favorable season it may be cut four or five times. After each cutting it is useful to draw heavy harrows over the land, or an instrument made on purpose resem- bling harrow teeth, the teeth of which are flat, and cutting the soil like coulters. It will not injure the plants, even if it divide the crown of the root, but it will destroy grass and weeds. Liquid manure, which consists of the urine of cattle and drainings of dunghills, is often spread over the lucerne immediately after it has been mown, and much invigorates the next growth; but if the land is rich to a good depth this is scarcely necessary. The lucerne will grow and thrive from seven to twelve years, when it will begin to wear out, and, in spite of weeding, the grass will get the upper hand of it. It should then be plowed up, all the roots carefully collected and laid in a heap with dung and lime to rot, and a course of regular tillage should succeed. The same land should not be sown with lucerne again in less than ten or twelve years, after a regular course of cropping and manuring. Cattle fed upon lucerne thrive better than on any other green food. Horses in particular can work hard upon it without any corn, provided it be slow work. Cows give plenty of good milk HISTORY. 57 when fed with it. In spring it is apt to purge cattle, which with a little attention is conducive to their health. If it is given to them in too great quantities, or moist with dew, they run the risk of being hoven. These inconveniences are avoided by giving it sparingly at first, and always keeping it twenty-four hours after it is cut, during which time it undergoes an incipient fermenta- tion, and the juice is partially evaporated: instead of being less nutritive in this state, it is rather more so. An acre of good lucerne will keep four or five horses from May to October, when cut just as the flower opens. If it should get too forward, and there be more than the horses can consume, it should be made into hay; but this is not the most profitable way of using it, and the plant being very succulent, takes a long time in drying. The rain also is very injurious to it in a half dry state; for the stem is readily soaked with moisture, which is slow in evaporating. The produce in hay, when well made, is very considerable, being often double the weight of a good crop of hay. Many authors recommend drilling the seed of lucerne in wide rows, and hoeing the intervals after each cutting. This is the best way with a small patch in a garden, and when only a little is cut every day; but in a field of some extent, the lucerne, when once well established and preserved free from weeds by hand weeding the first year, will keep all weeds down afterwards, and the heavy harrows with sharp tines, used immediately after mow- ing, will pull up all the grass which may spring up. No farmer ought to neglect having a few acres in lucerne on his best land. Note carefully that Eham says, ''If the ground is trenched so much the better, and if the surface is covered with some inferior earth from the subsoil it will be no detriment to the crop.'' The fact is that earth from the subsoil often, in fact usually, has in it much more lime than surface soil, so that bringing it up is sometimes equivalent to a fairly good liming. It is a little difficult to explain the general neglect of alfalfa in England, since there are many soils there admirably suited to it and almost any of the well-drained English soils would now grow it well if they were well limed and enriched with even bare 58 ALFALFA FARMING IN AMERICA. mineral fertilizers. It may be the uncertain weather of British hay-making times has had a deterrent effect to the alfalfa growers, though it would seem more probable that the mere lack of knowledge of the subject was the main factor responsible for the fewness of alfalfa fields there. The writer has seen as thrifty alfalfa in Kent as he has seen anywhere in the world, and has marvelled at its small extent till he was told that the entire crop was fed green to the work horses. In America a number of men wrote enthusiastic- ally of the lucerne plant. It is certain that George Washington grew it at least to some extent, and Thomas Jefferson, on a kindlier soil, grew it so well that in one of his letters he mentions the joy that contemplation of his fields of lucerne gave him. To- day no alfalfa is grown on either of these farms, nor in their neighborhood. Is it that eastern farms are less fertile now, or is it that their owners are less prudent, enterprising and careful? In New York Robert Livingstone wrote of it and many men experimented with the plant, some with success, some without. In few localities in the east- ern states, however, did it gain a permanent foot- hold. There were several reasons for that. One principal reason was that alfalfa does not mature seed along the Atlantic seaboard except during very dry summers ; thus it was necessary to import fresh seed from Europe constantly at considerable trouble and expense. Then the plant's nature was not un- derstood, its lime requirement was not known, much HISTORY. 59 land was badly drained and fields were ruined by not being cut at the proper time. Thus the enthu- siasts gradually became discouraged and it became a settled belief that lucerne could not profitably be grown in eastern America outside of a few re- stricted neighborhoods. As indicating the sentiment of the friends of alfalfa in those days we quote a letter published in the ^ ' American Farmer ' ' of 1823, the letter copied from the ^'New Brunswick Times.'' The method of sowing advised is curious, to sow in the spring with fall rye, and there may be a hint in this for others living today in similar conditions. Note the excessive price of the seed — 50c per lb., or $30 per bushel. The letter written by ^' A New Jer- sey Farmer ' ' follows : It may materially promote the interests of agriculture to offer through the medium of your paper a few remarks on the culture of lucerne. This article (frequently denominated French clover), I have found by experience to be not only one of the most con- venient; but also the most profitable of any grass which can be cultivated. It vegetates quicker in the spring than any other grass, it resists the effects of drouths, it may be cut four or five times in the course of the season, and it will endure for at least twelve years without being renewed. Of all other grass it is the most profitable for soiling. I am fully of opinion that one acre properly got in would be sufficient to maintain six head of cattle, from the first of May until November, for before it can be cut down in this way, the first part of it will be reacfy for the scythe. English writers, have recommended the drill system for this arti- cle, but in this climate I have found this to be entirely fallacious. The proper mode to be adopted is to have your land in good order, to sow it broadcast, and to get the seed in during the month of April or May. The plan I would recommend would be to sow fall rye at the rate of 15 to 20 pounds to the acre with it. The effect of this is that the rye vegetates quickly, and serves as a nurse to the young grass against the heat of the scorching sun, and by the time the grass attains sufficient strength to protect itself, say in four or five weeks, the rye withers and apparently 60 ALFALFA FARMING IN AMERICA. dies. In the spring, liowever, tlie rye will again come forth mixed with lucerne, will add much to the quantity on the ground, and prove a most excellent feed for cattle. The rye cut green in this way and before getting into seed will admit of being cut two or three times in the course of the season, with the lucerne before it decays. The kind of soil most suitable for this culture is a dry mellow loam, but a sandy or clay loam will also answer, provided it is not wet. In a favorable season, the lucerne may be cut the next fall after sowing. After the first season you may generally be- gin to cut green for cattle by the first of May, which saves your young pasture and is in every respect a very great convenience, as hogs and every description of animals devour it with equal avidity. Backward as this season has been, I have been furnish- ing a copious supply every day to seven cattle, since the 5th of May. The seed can be procured at Thornburn's or other seed stores in New York, at 40 to 50c per pound. The following notes on the culture of alfalfa and sainfoin are from a book called ^'Practical Farmer" published in 1793 by John Spurrier and dedicated to Thomas Jefferson. Mr. Spurrier was a transplanted English farmer. It is curious to note how nearly he came to knowing how to grow each of these crops, and how vitally he failed to grasp the truth that these plants thrive on ''gravels" when these gravels are composed of limestone pebbles, not necessarily when they do not! This quotation is presented through the courtesy of J. M. Westgate : Saintfoin took its name from the French; for the word Saint- foin, translated into English, is Holy-Hay, which name they gave it from its excellent nutritive quality. There may be more benefit reaped from this grass than any other; as you may get a very great crop in the most dryest land, on hills, gravels, sands, or even barren ground; and it will so improve all those lands in such an extraordinary manner that they will bring great crops of any sort of grain after it. The stalks of the plant in poor land will be two feet high, and in rich land it will grow as high as six feet. It has tufts of red flowers, of three, fn^r^ or five inches in lensfth of thfi honey, suckle kind: they are so beautiful and sweet tliat 1 Have seen HISTORY. 61 them much esteemed in a garden and called the French honey- suckle. This plant will make twenty times the increase in poor ground than the common turf; and this is owing to its having a long perpendicular root called tap roots, as well as numbers of hori- zontal ones; the perpendicular ones sink to a great depth to at- tract its nourishment. The length of this root is scarce to be credited by any but those who have seen it; I have drawn it out of the ground near fourteen feet; and some have told me that they have traversed it to double that length. This is the reason I presume why this plant will bear drouth, when all other grasses have been burnt up by the excessive dryness of the sea- son. I have at one cutting got two tons of this hay per acre. Cold, clay, or wet land is not suitable for this grass, as it would chill and rot the roots. The long root of Saintfoin has near the surface many horizontal roots issuing from it, which extend themselves every way; there are of the same kind all the way down, as the roots go, but they grow shorter and shorter all the way. Any dry land may be made to produce this valuable and use- ful plant, though it be ever so poor; but the richest and best land will produce the greatest crops of it. The best method of sowing it is by drilling, but the earth must be very well prepared and the seed well ordered, or else very little of it will grow. The heads of these seeds are so large and their necks so weak, that if they be above an inch deep, they are not able to rise through the incumbent mould, and, if they are not covered, they will be malted; that is, it will send out its root while it lies above ground, and be killed by the air. The best season for planting it is the beginning of spring; and it is always strongest when planted alone. If barley, oats, or any other grain sown with the saintfoin, happen to be lodged afterwards, it kills the young saintfoin. The quantity of seed to be drilled or sown broadcast upon an acre of land will depend wholly on the goodness of it; for there is some seed, of which not one in ten will strike; whereas, in good seed, not one in twenty will fail. The method of knowing the goodness is by sowing a certain number of the seeds, and seeing how many plants are produced by them. If it is above two years old, it will not grow. The external signs of the seed being good are that the husk is of a bright color rather of a purple, and the kernel plump, of a light grey or blue color. If the kernel be cut across, and appear greenish and fresh, it is a certain sign it is good. If it be of a yellowish color, and friable, and looks thin and pitted, it is a bad sign. The quantity of seed allowed to the 62 ALFALFA FARMING IN AMERICA. acre in the drill way is much less than by sowing broadcast. A bushel of seed to an acre of land is 20 seeds to each square foot of land if sown broadcast, which would be sufficient; but there must be an allowance made for casualties. The quantity of good seed I have found by experience is for sowing broadcast, two bushels, and for drilling, one bushel. And as the saintfoin does not cover all the ground the first year, which spaces are generally occupied by weeds, to remedy this, when I have sown it broadcast, I have sown four or five pounds of clover seed with it to the acre, which has answered a very good purpose, as I have then had a crop the first year. The saintfoin is but a slow grower at first; the second year perhaps will not exceed a clover crop, but afterwards it increases every year for six or seven years before it comes to its full per- fection; and as that increases, the clover goes off, and makes room for it. This valuable plant will keep in perfection for twenty years, if you only give it a slight top dressing with soot or ashes, once in four or five years. The first summer, nor early the next spring, it should not be fed, because it will be apt to bleed itself to death; for the sweetness of it is such, that it will entice cattle to bite into the knot in the ground and spoil it; but afterwards, when it has gathered strength, the best method will be to mow the first crop, and seed it after, which is excellent for cows and sheep. This plant, as well as trefoil, will not thrive in a wet moist soil; and as saintfoin thrives best on high grounds, it is a great advantage in the article of making it into hay, as it has greatly more advantage of the sun, and less to fear of mischief from wet, than grass which grows in low grounds. On the high grounds, the wind will dry more in an hour than it will in meadows that lie low in a whole day; and often the crops of saintfoin make a very good hay in the same seasons in which all the grass hay is spoiled. The sun on the high grounds has also a more benign infiuence, and sends off the dew there two hours earlier in the morning, and holds it up as much longer in the evening; by these advantages the saintfoin has more time to dry, and is made with half the expense of common hay. Saintfoin for hay should be cut when it is half blossomed, and managed the same as before directed for clover. If saved for seed, it must be the first cutting. You may know when it is ripe by the seeds coming out easily in your hand. Dry it in the field, and thresh it there on a cloth, as it will shed and you will lose great part of the seed if yon carry it to the barn. The straw will be as good as hay for horses; and the hay, when it has been HISTORY. 63 well got in, my horses that have worked hard have been kept on it alone without any grain, have been so fond of it that they have refused beans and oats mixed with chaff in the common way for it. Sheep also will be fatted in pens in winter, with only this hay and water, better than with corn, peas, oats, and the like. In short, there is no hay that is made is equal to it, and the produce will be double that of clover. The land where it is sown should be very clean from weeds, under a fine tilth; which is best done by a turnip fallow. Lucerne is the plant which the ancients were so fond of under the name of Medica, and in the culture of which they bestowed such great care and pains. Its leaves grow three at a joint, like those of the clover; its flowers are blue, and its pods of a screw-like shape, containing seeds like those of the red clover but longer and more kidney shaped, and the color all yellow. The stalks grow erect, and after mowing they immediately grow up again from the parts where they were cut off. The roots are longer than the saintfoin, and are not single, but some times they run perpendicularly in three or four places from the crown. It is the only plant in the world whose hay is equal to the saintfoin for the fattening of cattle; but its virtues in that re- spect are very great. It is the sweetest grass in the world, but must be given to cattle with caution, and in small quantities, otherwise they will swell, and incur diseases from it. Though the common methods of husbandry will not raise lucerne to any great advantage, yet the drilling and the horse- hoe husbandry will raise it, annually increasing in value to the owner, and make one of the most profitable articles of his busi- ness. The soil to plant it on must be either a hot gravel, or a very rich and dry land that has not an under stratum of clay, and is not too near springs of water. The natural poorness of gravel or sand may be made up by dung, and the benefit of the hoe, and the natural richness of the other lands, being increased by hoe- ing and cleansing from grass, the lucerne will thrive with less heat; for what is wanted in one of those qualities must be made up in the other. The best season for planting of it is early in the spring, the earlier the better; for then there is always moisture enough in the earth to make it grow, and not too much heat as would dry up its tender roots, and kill it after the first shootings. About a pound and a half of seed will be enough for an acre. The planting it in autumn in some climates might do; but here the winters are too cold, which would kill great part of the tender plants, and greatly stunt and injure those it does not kill. 64 ALFALFA FARMING IN AMERICA. The number of the lucerne plants should he less than those of saintfoin to an acre, because they grow much larger in this way of management, and each occupies a greater space of ground, and produces a larger quantity of hay. The quick growth of this plant requires that it should have large supplies of nourishment, and good room to grow in; and it is better in all things of this kind to err in setting the plants too far distant, than In setting them too near. The most fatal diseases incident to lucerne are starving and smothering; for this reason good cultivation is necessary to it, and the often turning the earth with the hoe all about it. By this means, a plant that in the common way of sowing would not have been more than eight or nine inches high, will be four or five feet, and will spread every way so as to produce a quantity of hay, more like the cutting of a shrub than a plant. The plants should stand at five inches distance in single rows, and the intervals between these rows must be left wide enough for the use of the hoe plough, (if managed according to the horse-hoe husbandry) ; but if hand hoed, one foot between the rows will do: for which I will refer you to my experiments on fallow crops, where you will find that by this method I had at the rate of four tun lucerne hay per acre. But lucerne sown in drills so near will in a few years meet in the rows, which will hinder the mould being stirred, when it will starve for want of nourishment, and thereby wear out. Lucerne is of much quicker growth than saintfoin, or any other grass. I have cut it four times in a season, whereas the others are seldom cut above twice. Lucerne is to be made into hay, the same as saintfoin or clover; . but this must be observed, that it is always to be cut just before it comes to flower. It is a fine food, if cut for the cattle green, it is so sweet and full of nourishment but it must be kept clean from natural grass, as that soon choaks and kills it. Of tlie introduction of alfalfa into the Pacific coast region we have less recorded. Naturally the people of Spanish blood, settling California from Mexico, brought their favorite farm seeds with them, seeds of their best suited farm crops; among these was alfalfa. Not much alfalfa was grown in California by the Spanish colonists, enough probably to give them credit for the introduction there, as they cer- HISTORY. 65 tainly must claim credit for its introdnction into southwestern Texas and pro'bably into New Mexico and perhaps into Arizona. It took the keen prophetic insight of tlie Ameri- can, however, to see in the alfalfa plant the wonder- ful possibilities that lay within it. Gold was discov- ered in California in 1847 and immediately began a great rush for that land. Many men went by the long route ''around The Horn." In Chili a good land and fertile, with well developed agriculture, ships tarried often for a little time. The passengers wearied with the long sea voyage took themselves with delight to the fields. There they saw alfalfa for the first time. Some of them took seed of it with them to California. Others sent back there for seed and sowed it in California, land of promise. Cali- fornia proved to have suitable soil and climate, and alfalfa throve there astonishingly. Gold could not always be found with pick and shovel, it could with- out fail be found by alfalfa roots. For the first time in its history alfalfa became a great crop and men began to plant it largely, to talk of it and write of it. Probably no one knows more of the early history of alfalfa in California than E. J. Wickson, Director of the California experiment station and dean of the agricultural college. My letter to him containing questions and his answers thereto is presented : I am delighted that you will undertake to help me in my alfalfa investigations. I know of no man better fitted than you. The points I particularly wish to know are not very difficult of answer. Question: On what date did the real introduction of alfalfa in California take place, and where was it sown? A.nswer: I have record of sowing alfalfa by W. E, Cameron, 66 ALFALFA FARMING IN AMERICA. near Marysville in the Sacramento Valley in 1851, who continued until he had 270 acres in 1858. Question: What was the source of the seed? Answer: From Chili and the plant was called Chili clover until its Spanish name alfalfa was taken up. It was some time later when its botanical identity with lucerne was known. Question: Were there many alfalfa fields or patches in use by the Mexicans, or earlier Californians, prior to the occupation by the United States? Answer: I never heard of any. Introduction is believed to have been by Americans from Chili with which country there was much trade and where stops were made coming round The Horn. Question: What is the oldest alfalfa field that you know of to- day, and about how many years? Answer: I have no definite instance. The plant on good soil- that is free soil where no root injury comes from standing water — is counted upon for more than 20 years of profitable growth. Question: About what percentage of carbonate of lime exists in the most productive alfalfa soils of California? Answer: We are now growing alfalfa on nearly all productive- soils, the acreage on the heavier soils, formerly held to be un suitable, increasing every year. The average lime in California soils (average of 262 analyses) is 1.25%. Question: What would you consider an average yearly pro- duction per acre of alfalfa hay? Answer: Five tons. Question: What is the maximum that you have known? Answer: I cannot be sure but think it has gone up to 12 tons. Question: We hear very astonishing stories of long alfalfa roots; how long a one have you actually seen measured, or had knowledge of that you considered authentic? Answer: 24 feet but others claim up to 30 feet. Concerning Henry Miller's alfalfa I wrote in ^'The Breeder's Grazette'' in September of 1900 as follows : Away back in 1850 there landed in San Francisco a lad with fifty cents in his pocket, a brave heart and a determination to work and succeed in this new world. He went to work in a butcher shop. Soon he had a small shop of his own. Then it was a large shop. Then he bought, in 1858, a little land on which to hold some cattle. In 1860 he bought land in the San Joaquin HISTORY. 67 Valley. It was dry semi-arid land. Some of his associates won- dered what he would do with it. He bought more. After a time, I think in 1872, he took out a canal to water it. In 1873 he im- ported some alfalfa seed from Chili. He sowed 7 acres, a large operation at that time. Gradually the holdings of land and of cattle increased. Today the firm owns about a million of acres of land, most of it in California. They have about 100,000 head of cattle. They have about 120,000 sheep. This growth all repre- sents the profit made in growing, killing and selling cattle and sheep. Henry Miller is one of the wonderful men of our time. He is one of the men with foresight and faith. His manager, Mr. Schmitz, of the Poso ranch at Firebaugh, has been with Mr. Miller for thirty years. He told me many incidents that showed the kind of stuff of which the man is made. Here is an instance: When the water was out Mr. Schmitz was instructed to irrigate and sow barley. The land was not prepared for irrigation. Mr. Schmitz and his Irish laborers knew little or nothing of the art. They had a tremendous time of it. Mr. Schmitz lived night and day in the fields, trying to manage the elusive water. The crop was a fair one, but netted a loss of some $2,000. Mr. Schmitz re- ported and asked to be allowed to resign. "What for?" asked Mr. Miller. "Well, it does not pay. I would not mind working if I could see that it was a success," he replied. "See here, Mr. Schmitz, suppose you look after the work and let me do the figuring," said Henry Miller. When alfalfa proved the success that it did the solution of the problenq. was in sight. After that it became a simple matter of steadily enlarging the areas of irrigated lands, of alfalfa fields, of cattle. Today on Mr. Schmitz's division of Poso farm of 160,000 acres there are 20,000 acres of alfalfa. There are 25,000 acres of irrigated native grasses. He cuts 15,000 tons of alfalfa hay. He grows 50,000 sacks of barley and 5,000 sacks of Egyptian corn. .His tenants grow some 100,000 sacks of wheat and 20,000 sacks of barley. Poso farm carries about 25,000 head of cattle. It has about 40,000 sheep and ships about 5,000 hogs each year. Do those figures make you dizzy? Well, I will not deal much in figures from this time on. You can get the idea that it is not merely a ranch, a farm, but almost a state, certainly a prin- cipality in itself. If there is anything like it in the world I have not heard of it. We rode up the great weir in the San Joaquin River, whence the canal starts that leads off westward and divides the watered land from the dry. A lovely river is the San Joaquin at this time of the year. Calm, neither hurrying 68 ALFALFA FARMING IN AMERICA. nor loitering, it sweeps on toward the bay, flowing under cool shadows, stretching out wide over shallower reaches, and em- bracing tree-embowered islands. It bears water enough to make a garden of the entire valley, could it be held back until needed. The canal is large enough for steamships at the head; it divides after a time, and divides again and again as needed, until there is a vast network of ditches, hundreds of miles, so much that Mr. Schmitz declined to even guess the total length. Italian laborers take the water from the ditches and spread it over the land. Dikes, following the contours, make it spread over all. The alfalfa fields are irrigated three times each season. There is so large an area to water that it is not practical to get over them oftener than that, yet it would doubtless be better if it could be done. And the cattle graze the alfalfa, except that one crop is taken from the field and made into hay for winter feeding. Alfalfa grows rank over here. It is the best that I have yet seen in California. The cattle thrive on it as a matter of course. They are careful not to turn hungry cattle on alfalfa pasture. They must be first filled up with hay or grass. After once be- coming accustomed to green alfalfa they are never taken away, so do not get hungry, gorge themselves and bloat. That seems the explanation of it all. They graze it with many thousands, yet lose hardly any at all. And sheep are treated the same way. I never saw such lambs as these alfalfa lambs. They are born early, in February generally, and they run on the alfalfa until they go to the butchers. Often their mothers are fat enough to go also in a short time after the lambs are taken away. The herder merely restrains them from roaming about over the fields and trampling down too much at a time. The alfalfa is not grazed short, there is no chasing the sheep away after they have eaten a little, there is no running them about to keep them from bloating; they are simply gotten used to it and left alone until they get fat. And the loss is very light indeed. Shropshire rams are mostly used. The ewe flocks are largely kept up by purchase of range ewes. The increase reaches as high as 120%. The quality of the Miller & Lux cattle is very good — much better than the average. Very many registered and more pure-bred but unregistered Short-horns are used, but the California idea pre- vails that a Short-horn is not good unless he is red. And, by the way, there are no Short-horns in California; there are only "Durhams." This term is also used in Utah and Nevada. At present the cattle are kept until they are three and four years old. The Q-uestion of early maturity seems to have been little considered. I saw them dipping cattle as a preventive of Texas fever. The HISTORY. 69 dipping vat Is made exactly on the model of a sheep-dipping vat. It is about 75 feet long and the cattle are put through very rapidly and without loss. The lime and sulphur dip is used, to which a quantity of crude petroleum is added. This certainly destroys the ticks if any exist and for a time keeps off the flies. As to the ultimate benefit, as they are put back on supposedly in- fected pastures, I think it a matter of experiment. It costs about five cents to dip a steer. It makes a few orphan calves, that is the worst of the practice. About 3,000 can be dipped in a day at one of these plants. The getting of the cattle to the dipping vat is the main part of the work. As a matter of dipping, this is entirely successful. None of the loss or difficulty that the Gov- ernment dipping experiments reported are encountered here. And I have no doubt that the dipping removes the ticks. Winter feeding is carried on here in an immense way. There is quite an elaborate plan of procedure. In order to understand it you must consider two propositions: one that the hay has in it more or less of "foxtail" grass, which has on it disagreeable barbs, and that it is desired to mix with the hay a very small amount of grain. The problem is to get rid of the danger of the foxtail, and to mix four pounds of ground barley with some 30 pounds of alfalfa hay and make a ration for a steer. All the hay is cut through great Ross cutters, then it is put on the floor of the great feeding barn and wet down. This barn holds no cattle. Then the ground grain is mixed with it. It stands for about forty-eight hours, until it becomes soft and slightly fermented, then it is taken out and fed. It is in the same condition as alfalfa silage. The cattle thrive better on 34 pounds a day of this ration than on 50 pounds of uncut alfalfa fed out of doors on the ground. That is what these men believe, and who will argue against so much experience? But the amount of labor in- volved would stagger an ordinary mind. Imagine handling 12,000 tons of alfalfa in this way, as Mr. Schmitz must do on his own farm. The amount of grain fed in proportion to hay is very small, it would seem. Yet the hay is of prime quality; it is as rich as hay can possibly be. The method of making hay on this ranch is interesting. It is cut and raked with ordinary tools. It is then caught up by large buck rakes on wheels that carry about 700 pounds to the stack. It is lifted by a great sling, and swung over the rick by a sort of crane. Or it is loaded on wagons and hauled farther and lifted by a Stockton fork. These forks are 5, 6 or 7 feet long; they take up enormous loads and are distinctly better than the harpoon or grapple forks used East. I mean to have one on our own ranch and one in Ohio. The ricks are not left sharp, and 70 ALFALFA FARMING IN AMERICA. in our wet Ohio climate would spoil badly. The haymakers ar* largely Italians; the irrigators are Italians. Spaniards do some of the work. Basques do some of it, Mexicans do a part, Portu- guese do a part, Chinese do the cooking and gardening. Ameri- cans do a little of everything, and are often foremen. Mr. Schmitz speaks three or four languages, and finds them almost indispensable. Things must go wrong very often on such a vast ranch; there must be perplexities and vexations enough to vex a saint. Think then how convenient to have three or four lan- guages in which to express your disapprobation with things in general and the case in particular! This much for one man's fortunes as built on al- falfa roots. But other men were awakening to the value of the plant. Soon it spread over much of California, and thence eastward into Utah where it was called lu- cerne and where it throve as well as it could thrive anywhere on earth. In Utah were many sm.all farm- ers, careful men, keeping cows and horses and pigs with poultry and bees. To these men alfalfa was a god-send. The Mormon farmers began to cut alfalfa for seed. From Utah seed nearly the whole west has been planted. Colorado took alfalfa next; fields of good size were being sown in 1886 when first the writer traveled through that state. A little later alfalfa suddenly sprang into great prominence in Colorado. By its ability to enrich soils and make lands fit for potatoes, beets or any other thing it came into great favor. A hundred villages in Colo- rado are built upon the alfalfa plant. Alfalfa is more to Colorado than all her gold, all her silver, all her wheat or sugar or forests. To take away alfalfa from Colorado would destroy the very foundations of her prosperity and nothing known upon the earth HISTORY. 71 could possibly replace this rich, beautiful and won- derfully useful plant. From Colorado alfalfa came naturally into Kan- sas, beginning to be an important factor there about the year 1894. At first it was grown only along the Arkansas river, and in the dryer parts of the state. Gradually it overspread nearly all of Kansas, being of most importance on the richer, dryer, sweeter soils. Nebraska followed Kansas in taking up alfal- fa growing. Along the Platte River it established itself strongly and in the western part of the state, while gradually, surely its roots penetrated nearly every part of the state. East of the Missouri Eiver alfalfa made slow progress. Iowa grew a little, Mis- souri on her alluvial soils along the Missouri and Mississippi rivers planted fields and gradually the growth extended. Illinois undertook alfalfa cul- ture in 1898 or earlier, but as yet the industry there is hardly more than in its experimental stage, some men having made notable success, but many having failed. Wisconsin grows much alfalfa, having soils well drained and rich in lime. Minnesota began its culture in 1857 when Wendelin Grimm came from the little village of Kulsheim, Germany, bringing with him a little bag of alfalfa seed from his old home in the Grand Duchy of Baden. This was the "ewiger klee'' or everlasting clover of Grimm, and from that day to this in Carver Co., Minnesota, al- falfa has been grown. Indiana attempted alfalfa culture and the experiment station published a bul- letin charging that alfalfa was not particularly 72 ALFALFA FARMING IN AMERICA. adapted to that state. In later bulletins this mis- taken idea has been co^rrected. Alfalfa is now grown with much profit in many parts of Indiana and only that many fields yet are waiting to be limed, drained and enriched is all that prevents Indiana growing at least a million tons each year. Alfalfa culture in Ohio came probably with the efforts of the writer and his brothers, as detailed in the introduction to this book. Pennsylvania pub- lished a bulletin in 1904 detailing how to grow al- falfa and since then much has been done in prelim- inary work of experimentation and it is now known that alfalfa will grow almost anywhere in that state where the land is drained, limed and enriched. Mary- land grew alfalfa during colonial times and a few farmers kept it up in a small way till this day. To- day alfalfa is grown in every county of the state and with the new knowledge of the lime requirement for alfalfa, its culture is now on a sure footing and the crop is destined to be one of the most important in the state. New Jersey, once in colonial days grow- ing it well, has suffered a relapse yet there are many men over the state succeeding with it, and when the need of lime and drainage is understood, doubtless New Jersey will also grow large areas of this beau- tiful forage. Director Edward B. Voorhees of the New Jersey experiment station has done notable work in teaching the essentials of alfalfa culture and especially in calling attention to the marvelous power of alfalfa to enrich land when the crops are fed and the manure applied. HISTORY. 73 In New York alfalfa has been grown continuously for over a century. The following notes on the early history of alfalfa in New York, by F. E. Dawley, are of value and interest : From 1791 to 1800, Mr. Robsrt Livingstone, of Jefferson county, New York, conducted some experiments, many of which were successful, and from investigations made in the vicinity of Le- Raysville, in that county, I feel certain that there are still grow- ing wild there alfalfa plants which are descended from his orig- inal plantings. Following these experiments, the next that I am able to get any authentic record of are those made about 1812 in Onondago county by Sterling Lamson and Moses Dewitt, and in Jefferson county by Ezra L'Hommedieu. About four miles west of Cedarvale, in this county, a few scattered plants have been growing for years on a side-hill, which I believe came from the seeding made by Mr. Lamson, as I can get no record of its having been planted in that vicinity until within the past ten years, and these scattering plants have been known there for at least forty years. In a diary kept by this man in 1815, the state- ment is made about alfalfa, that it grew so coarse that the ani- mals would not eat it dry and that it was very dangerous in pastures because of producing bloat. In 1851 a cask of alfalfa seed was distributed among members of the American Institute and many patches were grown in New York, New Jersey and Connecticut. In 1865 in this section there was great interest in bee-keeping. A man by the name of Rosenkranz traveled all over the country selling rights for using the Langstroth bee hive and giving in- struction in bee-keeping. He had traveled extensively on the Pacific coast and had become greatly interested in alfalfa as a bee-food. Among the bee-keepers in this section who were in- duced to try alfalfa were my father, Wm. Dawley, James Patter- son, Charles Phillips, William A. House, who lived on the farm which I now own, and many others. In the western part of the state those who tried alfalfa were not very successful, although Mr. Phillips had a remarkably good stand at one time. I be- lieve that all of them sowed it too thinly and that the proper bacteria were not present in sufficient quantities to make it a success. One of these experimenters sent to California for a bag of seed, which was shipped to him in the hull, being very dusty and foul. From this lot of seed, however, sent about 1870, on the farm which I now own can be traced, I think, the origin of successful alfalfa growing here. 74 ALFALFA FARMING IN AMERICA. A. little later than this Dr. E. Lewis Sturtevant, who had charge of the state experiment station at Geneva and was very much interested in alfalfa growing, recommended its planting quite largely and many fields were put out. The failures in this state outnumber the successes greatly; still in the townships of Onondago, Dewitt, Geddes and Manlius, Onondago county, and Sullivan in Madison county, there are to be found many acres of very successful growth, and on high lands in these counties four-fifths of all the hay cut last year was alfalfa. At the present writing alfalfa is being grown con- siderably over nearly the whole of the state of New York, but chiefly in the limestone regions of central New York, its greatest use being probably in Onon- daga county. There is much limestone in New York and the farmers are generally intelligent and enter- prising. It would seem that as soon as they realize that by abundant use of carbonate of lime, making their soils somewhat like those alkaline soils of Colo- rado and California, they can grow alfalfa as well as the West, and that alfalfa in New York is worth fully double what it is in the West, they will take the mat- ter up in serious earnest and spread its culture fast and wide. It is interesting to know that in old Virginia, where once George Washington and Thomas Jefferson vied with each other in growing lucerne, there are now at least 'two great farms growing alfalfa in hundreds if not thousands of tons as is done in the West, and perhaps more interest is shown in alfalfa culture in Virginia at this time than in any other state alon^ the Atlantic seaboard. Of the southern states Alabama, Mississippi, Ark- ansas and Louisiana are doing most with alfalfa, HISTORY. 75 Louisiana perhaps leading. Alfalfa revels in alluvial soils rich in lime. These soils are found along the deltas of the Mississippi, Arkansas and Red rivers. A great per cent of the state of Louisiana is adapted to alfalfa growing once it is drained and the soil made ready., Mississippi has alluvial '^bucksho't" soils along the western side and limestone black soils along the eastern side. In each of these soil types alfalfa thrives. It is a remarkable fact that lands that can be bought for $25 to $50 per acre in these states will grow four tons of alfalfa hay per acre and the hay is worth at present writing $20 per ton. Albama has similar limestone soils and is doing well with alfalfa thereon. The common upland soils of Alabama will grow alfalfa when well limed and en- riched and it is thriving in many places where right preparation has been made. With all this encouraging evidence of the spread of alfalfa culture there remains much to be done. Not one acre in a thousand is made ready for alfalfa that should be made ready. Think of Iowa with her wide fields of maize, steadily growing less and less fertile because of the drain made upon them ; think of her herds of cattle, her sheep, her cows and swine all craving alfalfa to balance up a ration too exclu- sively, corn. Think of Illinois, her high priced lands, her fields famed for riches but their fertility steadily diminishing, her need of foods rich in protein, her need of soil building. And Indiana with her poorer soils and smaller farms needs alfalfa on every farm she possesses, and Ohio needs it more with her thou- 76 ALFALFA FARMING IN AMERICA. sands of dairy farms and her sheep farms and pig breeding farms. The same is true of Pennsylvania and New York, only the need is greater, for the farther east one goes the higher priced is hay and the more wheat bran is bought to furnish protein to make milk or grow animals. All over America just now there is a quickening of the agricultural life. Men are awakening, gaining new courage, new hope. The young have higher as- pirations than ever before; farming is coming out from the ruts; it is no longer a disgrace to be a farmer. The best brains and best thought and best blood of the land are being devoted to agriculture. Alfalfa comes at opportune time. It fits in on every farm, once the soil is made right. It is a permanent thing. It is a mine of riches, a magazine of rich provender, a source of fertility wherewith to build animals and to build other soils. Alfalfa brings hope, courage and joy. It brings beauty to field and landscape. It covers over the scars made on the face of Nature, it stops the waste of erosion and soil leaching. Where it comes boys cease leaving the farm, bees come, and birds; the cows stand tranquil with full udders, land values advance, paint comes to the country school-house and happy children trudge along the lanes with well- filled dinner pails. And is it practical to grow alfalfa over all this region? It is practical. Alfalfa is one of the sim- plest and easiest things grown in the world. It is one of the hardiest plants known, one of the most HISTORY. 77 responsive. It is absolutely easy to grow alfalfa. There are no longer any mysteries about it. To teach the way so plain that anyone can follow and no one longer will fail is the purpose of this book. The writer is very earnest in this purpose. He repeats absolutely it is true that every farmer may have his alfalfa field if he has soil with water level down 36", or soil that may have the water level so lowered, and soil not entirely composed of peat. Sands, clays, alluvial soils, all alike yield to the magic of alfalfa, all alike robe themselves in living green, all alike yield rich forage and are in turn en- riched themselves by the alfalfa growing upon them. There are keys to unlock the m.ost stubborn soils. Today we have those keys. No longer should any man fail to make alfalfa grow. The day of ' ' experi- menting'' with alfalfa is over. The day of surely growing it has come. If any man will read carefully the plain directions in this book, will read and heed, he will grow alfalfa, whether he is in Maine or Mas- sachusetts, Dakota or Dahomey. VARIETIES OF ALFALFA. The botanical name of alfalfa is Medicago sativa. It belongs to the class of plants called legumes. Its relatives are the clovers, the peas, beans and locust trees. There are thousands of kinds of leguminous plants in the world and most of them have some use. Some provide food for men, as the peas and beans ; some provide forage for animals; all or nearly all have the power to enrich soils. There are more than 50 rather near relatives to the alfalfa plant. Some of them are annuals, some are biennials and some are perennials. Of them all only six have come into general use as forage plants, and of these only one or two have much merit. The descriptions following are from Prof. G. F. Freeman of Kansas : Alfalfa {Medicago sativa, Linn) is an upright, much hranched smooth or slightly pubescent perennial plant one to three feet high. The branches arise from a rather woody base which crowns a long tap-root. This root with its branches may extend three to twelve, or, in rare cases, even fifteen feet deep, rendering this species very drought-resistant on account of its being able to bring up water from the subsoil far beyond the reach of ordi- nary plants. The leaves are arranged alternately on the stem and are trifoliate or three-parted, each part being slightly broader above the middle and usually tapering each way, although the apex may be frequently rounded, blunt, or even slightly notched. The pea-like flowers, varying in tint from pale, almost white, to deep reddish purple, are arranged in rather elongated loose clusters borne on the ends of the many branches. The pods are spirally twisted through one to three complete curves, forming a coil one-fourth to one-fifth inch in diameter. This pod contains from one to eight seeds. The seeds are kidney-shaped, about one- eighth of an inch long and a little more than half as wide (78) VARIETIES OF ALFALFA. 79 From an agricultural standpoint this species is by far the most important, being probably the most widely grown and most valu- able forage plant in the world. Yelloiv lucerne or Swedish clover (Medicago falcata) is a perennial plant strongly resembling alfalfa, but it differs from alfalfa in being of somewhat lower, more spreading habit and having bright yellow flowers. It is a native of northern Europe, extending into Sweden and probably far into northern Siberia. It shows greater cold resistance than the ordinary alfalfa and is less liable to winter-killing. This species is probably identical with the yellow Siberian alfalfa recently introduced by Prof. N. E. Hansen of South Dakota. 8and lucerne (Medicago media Pers.). "There has been a dif- ference of opinion among European botanists in regard to the re- lationship of sand lucerne to other lucernes or alfalfas, viz., Med- icago sativa (ordinary alfalfa) and Medicago falcata (yellow lu- cerne.) Alefeld and other botanists unite common alfalfa, sand lucerne and yellow lucerne into a single species. Some botanists look upon alfalfa and yellow lucerne as distinct species and con- sider sand lucerne as a hybrid between them. Others regard them all as distinct species. The three forms, however, differ so widely in agricultural value and other characters that they can- not be treated together." "The ordinary distinguishing characters between alfalfa and sand lucerne are easily recognizable when the two are grown side by side." "The stiff habit of alfalfa differs from the more spreading habit of sand lucerne. The flowers of the former are bluish to violet purple, while those of the latter range from bluish and purple to lemon yellow, with many intermediate shades. The pods of alfalfa are coiled in about two turns, while those of sand lucerne are in about three-fourths of one coil. The seeds of the sand lucerne are lighter than those of alfalfa. Five hundred seeds of sand lucerne weigh from 0.8 to 0.9 gram, while the same number of seeds of common alfalfa weigh from 1 to 1.037 grams." "Sand lucerne, although a perennial like alfalfa, is not so pro- ductive in lands sufficiently moist for the latter or where it is hardy." However, in non-irrigated land in parts of Wisconsin and in Utah it is said to surpass any other variety except the Turkestan. In the moist climate of Michigan and in the irrigated land of Utah, on the other hand, it was much inferior lo the ordinary sorts. Seedsmen advertise it as being hardier, more drought- resistant and better able to stand grazing than alfalfa, and say 80 ALFALFA FARMING IN AMERICA. . that it will succeed on sandy soil which is too light to product profitable crops of other forage plants. Yellow trefoil or Hop clover {Medicago lupulina L.) is an annual species and may be distinguished from aifaifa by its more spreading habit, its shorter and broader tipped leaves, by its yel- low flowers, and, finally, by the fact that the pods are not coiled, as with alfalfa, although coiled to make a single incomplete spiral. These pods also differ from those of alfalfa in being black when ripe. This species has some value in moist regions, but is far inferior to alfalfa. Bur clover (Medicago denticulata Willd.) and Spotted Medic (Medicago arabica All.), like yellow trefoil, are also annual plants and have yellow flowers. They differ, however, from all of the above-mentioned species in having burry pods. , Although grown in some localities, they are of little agricultural conse- quence. Bur clover inoculates land for alfalfa growing or vice versa. They carry the same bacteria on their roots. Mellilotus, or sweet clover, also uses the same bacteria. This fact is useful since it often enables us to get hold of inoculated soil, or to sow one of the inferior clovers as a forerunner of alfalfa for the purpose of inoculating the soil or of enriching it and storing it with humus. Types and Varieties. — Alfalfa is remarkably vari- able. One can go into a field sown all of one sort of seed and select in it a hundred plants, no two having very close likeness. Much can be done and will be done to select varieties having desirable character- istics. Already the Colorado and Kansas experi- ment stations are doing considerable in this line, while other stations not so well located are also at work, notably Ohio, Minnesota and North Dakota, and the Department of Agriculture at Washington. Natural selection, -or the law of the survival of the fittest, has done much to create types. For example, VARIETIES OF ALFALFA. 81 alfalfa fLat has grown for some generations in hot Arizona becomes by elimination a type adapted to hot climates, and alfalfa grown for several genera- tions in Montana or North Dakota becomes also by elimination, and perhaps to some extent by muta- tion, a strain able to endure extreme cold. The practical lesson to be drawn from this vari- ability of alfalfa is that it is best to choose seed com- ing from a region in about the same latitude as one^s own farm. Alfalfa from Arizona is not hardy in Nebraska. Alfalfa from Montana would doubtless do poorly in Arizona. Alfalfa from California has not always proved hardy in the East. Alfalfa from France and Germany usually succeeds in the east- em States of America. When it fails it may be that the seed came from Algeria, up through France, and thus was in nature similar to the Arizona strain. Commenting on varieties J. M. Westgate, ag- rostologist in charge of alfalfa, investigation for the United States Department of Agriculture, says: Under most conditions, especially in the alfalfa districts, or- dinary alfalfa, whether from American or European grown seed, gives quite as satisfactory results as any of the special varie- ties. In certain sections of the country, however, special varie- ties of alfalfa have been found to be more valuable than the ordi- nary forms. Of these the Turkestan, Arabian, and Peruvian varieties have been introduced through the Office of Foreign Seed and Plant Introduction of the United States Department of Agriculture. Turkestan alfalfa was introduced into the United States in 1898, and has since been tried in all parts of the country. It has been found to be superior to the ordinary alfalfa in only lim- ited sections. It is decidedly inferior in the humid sections east of the Mississippi River, but has given somewhat better results than the ordinary alfalfa in the semi-arid portions of the Great Plains and in the Columbia Basin. In addition to its drought 82 ALFALFA FARMING IN AMERICA. resistance, it is also hardier than many of the commercial strains. Hardy alfalfa. — There have appeared during the past years several strains of alfalfa which are characterized by their hardi- ness and general ability to withstand conditions which are rather too severe for the best productions of ordinary alfalfa. There is some variation in the characteristics of these alfalfas, which may be grouped under this general head, but they agree in showing a considerable diversity in the color of the flowers, which varies from yellow to blue, green, and various shades of violet and purple. These colors are often clouded with a smoky hue. The predominating color is the violet of the ordinary alfalfa. The most conspicuous examples of hardy alfalfa are the commercial sand lucerne and the Grimm alfalfa of Minnesota. The sand lucerne has been grown for a number of years in this country. It has recently been found to be adapted to the colder and drier sections of the country, where it is proving the equal of any of the alfalfas under test. It seems particularly adapted to withstand the cold winters of the northern states, where ordinary alfalfa is very likely to winterkill. It is not always the heaviest yielder in sections where ordinary alfalfa succeeds, but its yields are always satisfactory, and it is espe- cially recommended for conditions where ordinary alfalfa does not succeed by reason of high altitudes, light rainfall, or severe winters. Its chief drawback is its tendency to lodge. The Grimm alfalfa, which has been grown for many years in Minnesota with excellent success, was brought from Wertheim, Province of Baden, Germany, in 1857, by a German farmer named Grimm. It is claimed by some that this variety has attained in- creased hardiness since its introduction into Minnesota. Dry-land alfalfa is the name usually given to ordinary alfalfa seed produced for one or more generations in the semi-arid sec- tions without irrigation. It is proving somewhat superior to ordi- nary alfalfa under semi-arid conditions, and as a drought- resistant alfalfa is about equal to Turkestan alfalfa and sand lucerne. Arahian alfalfa is proving of special value in the southwest- ern portion of the United States, where the winters are very mild. It is characterized by its large leaflets and the hairiness of the stems and leaves, quick recovery after cutting and very rapid growth during the growing season, and also by its ability to grow at cooler temperatures than ordinary alfalfa. On the other hand, it is extremely tender to actually freezing temperatures and generally winterkills in all except the southarrs and south western VARIETIES OF ALFALFA. 83 states. Its quick recovery after cutting and its longer growing season enable several more cuttings per season to be obtained than are possible for the ordinary alfalfa. Unfortunately, seed of this variety is not yet on the market. Peruvian alfalfa is similar to Arabian alfalfa, and is likewise characterized by its long growing season and lack of hardiness. It grows taller than Arabian alfalfa, but the stems are more woody. The seed is not yet on the market in this country, as it is not grown in Peru or elsewhere in large commercial quanti- ties. HABIT OF GROWTH. Alfalfa is a plant with marvelous root growth. It is not unusual to find alfalfa roots penetrating 6', 8', or even 12' into the earth. Very much deeper roots than these are reported. It is even said that alfalfa roots have been found that were 30' or more in length, and doubtless this is true in favoring soils. Alfalfa is a desert plant by nature. All desert plants root deep and root far. By aid of these deep roots desert plants tide over long drouths; if there is no moisture in the top soil there is perhaps moisture lower down. Alfalfa is a wonderful for- ager for moisture and for plant food. It loves deep, permeable soils. Because its roots penetrate so deeply into the earth it does not thrive when the water table of the soil is too near the surface. Permanent water ought to be down at least 36'' for alfalfa to thrive and if it is to last for many years even more depth is needed. Alfalfa Not a Grass. — Alfalfa is in no sense a grass. It has no communistic ideas whatever. Each alfalfa plant is a vigorous, hustling, independ- ent individual. It pushes its roots down, sometimes in one large tap root, sometimes in two or three large roots. It fills the earth with its hairy feeding roots. It makes a branching crown of many stems. The deeper the roots can penetrate the larger the crown will be. The better the soil for alfalfa the fewer (81) ALFALFA SIX WEEKS FROM SEED, SHOWING ROOT TUBERCLES. FROM LIFE BY EDNA HOPKINS. HABIT OP GROWTH. 85 plants will stand on the gronnd. One by one the weaker plants will be crowded out till at last the strongest plants will gain their normal position when there will be a plant for each square foot of surface in very deep, rich soils of the West, and these big plants with roots as large as one's ankle; or there will be four or more plants to the square foot, as in good land in Nebraska or Kansas; or there will be a plant for each 4'', as, in thinner, poorer and shallower soils in Ohio and the East. Alfalfa roots will not stand close together in any al- falfa sol], be sure of that. Nevertheless it is good to start them thick, since spare alfalfa plants are better than weeds in the field. Roots. — Alfalfa roots are very tough, strong and hard to cut. Penetrating the soil so deeply they make drainage channels when they decay and thus make the soil more alive. They are hard to plow. Once cut off they do not sprout again, though the top part if kept in moist earth will send out new fibers and may grow. Alfalfa is not hard to destroy by plowing; once cut off and cultivated a few times it dies. The large roots are not the ones that feed. The small fibrous root hairs penetrate each tiny crevice of the earth and absorb the soil moisture and thus drink in their food. Groing to great depths they are able to bring up mineral substances that may have leached down there. They are able to find moisture when the surface soil is parched with drouth. The Bacteria.— A]f 8i\f a roots absorb all that is in 86 ALFALFA FARMING IN AMERICA. the soil in tlie way of nourishmeiit, but what they find is not enough to satisfy the ambitions of the alfalfa plant. Therefore it calls to its aid a host of tiny slaves, the bacteria. All clovers have useful bacteria that live upon their roots and gather nitro- gen from the air. Then when the bacteria die the nitrogen is taken up by the plant and made into its tissue, into its leaves, stems and seeds. These bac- teria live primarily for themselves, fastening to the little root hairs. Soon these little root hairs push out tissue and enclose the bacteria in fleshy ex- crescences shaped like little grapes or seeds. These excrescences we call tubercles or nodules. They are as large as clover seed or larger, or smaller. They occur singly or in masses. Sometimes soils seem naturally full of these bacteria so that as soon as the alfalfa is sown they come on the roots. When this is true the alfalfa starts off with great vigor from the beginning and endures in thrift nearly al- ways. At other times soils are found to be barren of these bacteria and no nodules form upon the roots. Then the alfalfa seems half starved, weak, yellow, sickly. Where Bacteria Thrive.— In some soils it is im- possible to establish these bacteria by artificial trans- plantation or otherwise. When this is true alfalfa will never thrive. It may live for a time by aid of manures and cultivation, but it is not thrifty and it finally succumbs. It cannot withstand the onslaughts of weeds without the aid of these bacteria feeding its roots. They get their nitrogen and thus much of HABIT OF GROWTH. 87 their growth from the air. Thus the soil must have air in it or they cannot live. Waterlogged soils are barren of useful bacteria. Thus well drained soils are best for alfalfa. The bacteria thrive in soils alkaline, not acid. They cannot well withstand acid soils. They like a great abundance of carbonate of lime in the soil. It has not been shown that there is ever too much carbonate of lime in the soil for the good of the bacteria. Of other common western alkalies there may be a superabundance some- times of sulphate of soda and other more harmful black alkalies. The alfalfa root is the foundation of the alfalfa plant. When it is vigorous the whole plant thrives and resists disease and disaster. Resisting Temperature Extremes. — The alfalfa plant is hardy against cold. One could almost trace alfalfa to its original home by its very habit of re- sisting extreme heat and at the same time freezings cold. Desert countries have often blistering days and freezing nights. Alfalfa will be green nearly all winter down next the earth, waiting its chance. As soon as there is sun and warmth of spring it begins its growth. It is hardier than com- mon red clover and earlier to start in spring. Different strains of alfalfa have difPerent de- grees of resistance to cold. Cold affects the alfalfa differently at various stages of growth. When a warm spell in early spring pushes it up to a swift, succulent growth a hard freeze will lay it all over as though it were killed. It may indeed be seriously set back by such a freeze but usually it 88 ALFALFA FARMING IN AMERICA. straightens up again as soon as it thaws and goes on growing in a few days. No animals should ever be let tread upon it when it is frosted. Indeed it is better for the alfalfa never to be depastured. The First Growth. — The first growth is usually strongest, perhaps because of the long rest it has had during winter, and maybe because of more abundant soil moisture in the spring„ In Ohio it begins to bloom in late May or early in June. In more southern states it blooms earlier; sometimes in Louisiana it will bloom in April, or even earlier. The height of alfalfa at blooming time varies with the soil and variety. Ordinarily it is about 30 to 40'' high. In very good alfalfa soils with abundant irrigation and good suns, it may be much higher. The writer has grown it on his old Utah ranch fields so tall that only the heads of the deer were visible as they stood nearly submerged in alfalfa verdure. In some soils where roots cannot go deep it may not get higher than 24''. Time to Cut. — When bloom begins time is near for alfa'lfa harvest. One cannot judge by state of bloom altogether when alfalfa should be cut, however. Perhaps in some western soils it does not matter when it is cut ; no great harm results from cutting it at the wrong season. In all eastern regions, how- ever, it is ver}^ necessary that it should be cut at the right time. Failure to know when to cut it often re- sults in losing altogether the thrift of the next cut- ting, and maybe losing the alfalfa completely. One HABIT OF GROWTH. 89 cannot judge of when alfalfa should be cut by the appearance or non-appearance of bloom. Usually when it ought to be cut it will be in bloom. The only safe indication, however, is found in little shoots or buds that put out from the base of the stems near the earth. When these shoots put out, like little suckers, ready to make new growth, then cut the alfalfa and cut it immediately. Cutting must not be delayed else the shoots will become so high that they will be cut off with the hay. The alfalfa must not be cut before these shoots appear, because if this is done the alfalfa will not start off promptly, and when it does start will be singularly deficient in vigor and thrift. The reason is not known, but the fact is often observed that when a part of a field is mown only a few days too early and the rest of the field after the shoots have appeared there will be a difference of 100% or more in the yield of the next crop in favor of that cut at the right time. Further, when it is cut too early it often becomes unthrifty, rusted, yellow, sickly, and weeds and grass spring up and choke it. Thousands of ruined fields all over eastern America and in England trace their injury to having been cut at the wrong time. When it is mown off too soon all seems to go wrong with it. It may be that in some way the sap sours in the roots, the bacteria die, or some poison is secreted. Some such catastrophe is needed to ac- count for the behavior of the plants. Cutting for Soiling Weakens. — In England the writer has frequently observed that the habit there 90 ALFALFA FARMING IN AMERICA. of cutting alfalfa green and using it to soil liorses is responsible for great damage to the fields. At the end of a field where first the scythe began its work on immature alfalfa, it was so^ weakened that weeds and grasses came in thick and choked it out. At the other end of the field would often be good, thrifty alfalfa, because it had not been cut too soon. It is wise to cut as early as one can, and not cut before the appearance of the shoots, because thus a better quality of hay is secured. The Next Cutting. — Alfalfa cut at the right time makes astonishing recovery. The hay raked up, the field looks brown and bare for a few hours. Then comes the first tinge of green. In a day it is plainly to be seen. In two days it is green again. In a week no one should set foot upon it, and in four or f\.YQ weeks it is ready to cut again. Times vary, of course, but in Ohio if the first crop comes off about June 1, the next crop will be due about July 1 to 4. The same rule applies to the second cutting. It must not be taken away before the buds appear. The rule of waiting till new shoots appear on the bases of the stems applies to each cutting. As the summer gets older and dryer longer times elapses between the various cuttings. The second cutting will take about 40 to 45 days to mature, and the third cutting about the same time. At no time can one disregard the rule as to cutting when the shoots have appeared. Never cut alfalfa before these shoots come. Never delay cutting many days after they appear. iFiABit OF GROWTH. ^1 Cutting Promotes Thrift. — It is a curious fact that alfalfa needs to be cut in order to keep in thrift. This is especially true in the region east of the Missouri River. Doubtless it is in part an acquired habit, speaking strikingly of the length of years that our alfalfa has been sown and mown by man. In Ohio, for example, one will sometimes put down a fence through a young alfalfa field. Afterward he cannot mow quite close to the fence and there will be corners where the alfalfa remains uncut. It is then a continual object lesson of the effect of neglect, since the uncut alfalfa becomes unthrifty, a prey to leaf fungus and other diseases. As the season goes on the cut alfalfa retains its thrift and vigor; the neglected gets more and more unthrifty. At last weeds and grass overpower it and in a few years nearly every plant has disappeared, while the plants regularly cut alongside have quite retained their pristine vigor. Late Mowing Harmful. — ^In warm countries alfalfa, is always green and growing, so there is moisture enough, yet it has its periods of partial rest and its times of greatest vigor. In the arid and irrigated west it seems to do no injury to 'the alfalfa to mow it down late in the season, or to pasture it close in the fall. In the eastern states, on the other hand, it is distinctly hurtful to alfalfa to cut it down so late that it will not go into winter with a good growth covering it to hold the snow and protect the crowns. Always there should be a growth of at least a foot of alfalfa when killing frost comes. This 92 ALFALFA FARMING IN AMERICA. should not be depastured ; indeed, after killing frost no animal should be permitted to set foot in the alfalfa field. The difference in thrift and production between late mown alfalfa and that given fair treat- ment is very marked indeed. Many plants mown off in October will die altogether during the follow- ing winter. Thus when one means to^ plow the field, it is wise to mow it as late as convenient, since he gets quite a little hay from this fourth or fifth cut- ting, and at the same time weakens his alfalfa so that it plows easier. Very great injury in the humid regions has unknowingly been done the alfalfa by this very ignorance of its nature that led to its being mown late or depastured until winter. Danger from Treading. — In dry countries it seems to do little injury to alfalfa to let animals run on it all winter, even though they tread it down into the dust. In all the region of America lying east of the Missouri Eiver it is most harmful to alfalfa to tread upon it in winter, either by the feet of meu or ani- mals, or by wagons going over it. The line of direc- tion of a farm wagon going across a field can often be distinctly traced next spring by the two streaks of dead alfalfa plants. An alfalfa field should be a sacred place. Its gates should be closed and locked in September and not re- opened till May at the earliest, probably not till the first day of June, though these dates will of course be dependent on the latitude, now having in mind the climate of about parallel of latitude 40. Hardiness of the Plant. — Alfalfa then is one of HABIT OF GROWTH, 93 the hardiest plants in the world when exposed to certain trials and dangers. Drouths have no terrors for it. Cold has no terrors for it. Heat has no ter- rors for alfalfa. It dies, if it dies at all, of pneu- monia brought on by wet feet in winter time, by cancer brought on by undrained soils and floods of rains in summer time ; it dies from fungus troubles brought on by exposure to too much wet and by not Imving the fungus-affected tops cut away at proper time; or it dies because its allies, the bacteria, be- come diseased and forsake it. It is a Mexican, living by means of the hot peppers it consumes, the pep- per to the alfalfa plant being carbonate of lime. Given these things, dry soil with air in it and alka- line with carbonate of lime, not sour ; keep animals off it in cold weather, cut it three times a year, keep grasses from choking it, and alfalfa will endure in almo'st any land for half a century. Ice Will Kill. — There is one thing that may hap- pen, however, that no art of man can circumvent; that is ice in winter. There is a danger line along through Minnesota and parts of Wisconsin, probably extending through Michigan, where the warmth of spring comes before the cold of winter is out of the earth. Warm days thaw the snow, it makes a film of water over the earth ; this freezes hard and the ground is locked in icy fetters. This may kill the alfalfa dead. It may not happen more than once in several years. When it has happened the only thing to be done is to grin and bear it, plow the field, plant to corn or potatoes and re-seed the next year. Or it may be at once resown the same season. 94 ALFALFA FARMING IN AMERICA. Life of a Field, — What then is the profitable duration of an alfalfa field? In California, in some of the dry valleys with loose subsoil, it may ap- parently endure for a century. The writer has walked over an alfalfa field in Texas that was 40 years old; in Kansas perhaps 10 years, in Nebraska maybe the same, or nearly as long ; in Iowa probably four to six years. In Ohio alfalfa will endure for 10 years on the best drained land, and maybe for much longer time, yet the greatest profit is found in keeping it only while it is at its maximum efficiency, and that is about four years. Why expect or care to have it last forever? Alfalfa is one of the easiest established of clovers, nor is it costly to seed. It powerfully enriches the soil. Why then care to have it endure forever? It is wiser to use it only while in its full vigor, then as disaster overtakes it and one plant here, another there, dies out, leav- ing the stand thin, to plow it and re-seed after tak- ing off a crop or two of grain or roots, or whatever is required. In Maryland there is in Harford county a type of soil with such acid subsoil that alfalfa will not last more than a year or two in it. Yet some dairy- men have learned that it pays better to grow alfalfa than any other crop, leaving it stand only one year, then plowing and at once re-seeding. The practice is to sow in August, letting the alfalfa grow uncut that fall, then harvesting a good crop in late May, another in late June, a third crop about the first of August, at once plowing and thoroughly preparing HABIT OF GROWTH. 95 the land and re-seeding. Liberal fertilizing is done each year and thns quite heavy crops of hay are grown, although it has been learned that the alfalfa will not go through a second winter, the roots de- caying about 6'' below the surface. Doubtless the acidity of the subsoil is responsible in large measure for this result. If large amounts of lime could be applied to the surface just before plowing and thus turned under in direct contact with the sour sub- soil, in time even this land could be made to carry alfalfa more than one year. It is interesting and useful, however, to know that the alfalfa pays well to be resown each year when this is necessary. Essentials in Culture.— Alfalfa is no Laodicean. When it is healthy it is one of the happiest plants in the world', and when diseased one of the feeblest and most miserable. Fortunately making it healthy is pretty easy; it speaks in no uncertain tones and makes its wants known. The writer frequently takes a walk to the village along an old railway embank- ment, made in large part from limestone gravel, sur- faced with that and with limestone screenings from the crusher. The cl-ay in it is of limestone formation. It could not be said that this soil was exceptional in any way except that it is thoroughly drained, and has in it much lime. Scattered alfalfa plants grow along this embankment. For years they have grown and seeded there. They are beautifully green and vigorous plants and they never seem to get old. The writer, wandering down the railway line reflects, ''Why, here these plants in themselves tell all that 96 ALFALFA FARMING IN AMERICA. one needs to know about alfalfa growing. Just give drainage enough, give air enough in the soil, give lime enough, give seed, and alfalfa is the surest plant to grow there is." And this is true. Only these simple things need be known : to make the land dry, to make the land sweet with lime, or a little more than sweet, fairly alkaline with lime, then to make it fertile and sow good seed with faith and inoculation. What agricultural joys will follow such simple doings as these! What beautifying of landscapes, what riches in animal life, what wealth of farms and homes and villages ! Upon such simple fundamentals do great things rest. THE SEED-BEARING HABIT. Alfalfa left alone will bloom and produce seed on the first crop. If no fungus troubles its leaves it will continue to grow, bloom and produce seed all summer. In Utah the writer has seen bushes of alfalfa more than 6' high, covered nearly all over with bloom and seed. In all humid regions there will be leaf diseases that will make such condition of growth impossible. Fertilization. — The alfalfa flower is probably in- capable of self-fertilization without the aid of bees or other insects. F. Eoberts and Geo. F. Freeman, of the Kansas experiment station at Manhattan, have made many experiments in alfalfa breeding. Briefly, in planting a nursery of alfalfa plants, separated from each, other about 18^', very great variation was observed. One field was planted from seed gathered in Montana, the other from seed of so-called Turkestan alfalfa. The plants in each group varied remarkably in leaf and hardiness and habit of growth. In order to propagate the desirable types, study of the alfalfa flower was made, with its habit of fertilization. The following study or the alfalfa blossom is quoted from Bulletin 151 of the Kansas agricultural experiment station : The flower of alfalfa is rather an advantageous one for hand- pollinating purposes. The two wings have projecting processes which overlap, and assist in holding down the curved, spring- like column formed by the united group of stamens which en- (97) 98 ALFALFA FARMING IN AMERICA. close the pistil. A set of interlocking processes for the keel further assist in forming this spring-trap arrangement. When an insect of sufficient weight alights upon the keel, it depresses the latter, together with the enclosing wing petals; the trigger- like processes are pushed down past the upcurved column of the pistil and stamens, releasing them, and allowing the whole col- umn to spring up with considerable explosive force against the erect standard. At the time of pollination the style with the stigma has grown up above the stamens, and when released the stigma precedes the stamens, striking the insect's body first, in case the latter rests upon the keel, bearing its deposit of pollen brought from another flower. The burst anthers in turn dust off a new deposit of pollen as they are driven past the insect, which is thus equipped with a fresh supply of pollen to become avail- able for the next flower. Sometimes the shaking of the flower stems by the wind, or by the pelting of rain, many accomplish the same result. Self-fertilization may be secured also by visits of insects not yet loaded with pollen, which may, by setting off the explosive mechanism, bring about self-pollination. Since the pollen is shed before the stamen-pistil column is released, it happens that the stigma is already partly covered with pollen. Nevertheless, self-fertilization seems to occur but seldom in en- closed plants protected from insect visits. The explosive mechanism of the alfalfa flower has long been known, having been discovered as early as 1832 by A. P. De Candolle. In 1894, Burkill found it impossible to make seeds set in the unexploded flower, even though pollen were in contact with the stigma. He considers this fact to be due to the circumstance that the stigma does not become receptive to the pollen until its cells are injured by violent contact with some object. In proof he adduces the fact that he had caused unexploded flowers to set seed by pinching the stigma, by cutting off the tip of the keel^ or by rubbing the stigma with a stiff brush. It appears, there- fore, probable that insects secure the fertilization of alfalfa flow- ers largely by accidental injury to the stigma while endeavoring to cause the proboscis to enter; or else by exploding the flowers and causing the stigma to be dashed against the standard, the necessary amount of injury may be accomplished to enable thC pollen to become effective, in which case it may either be the already present pollen of the same flower, or foreign pollen brought by the insect that is utilized. Thus it is plain that insects play a large x^art in THE SEED-BEARING HABIT. 99 the fertilization of alfalfa blooms. The honey bee helps, no doubt, where it is plentiful, and also m-any other sorts of insects help — butterflies, millers, ants and various small insects that swarm in alfalfa meadows. Whether honey bees are useful in fer- tilizing alfalfa blooms is at present a disputed point, many men affirming that they secured as large crops of alfalfa seed before bees were introduced into their regions as they do since. However this may be, it is certain that bees pay large profits in the western alfalfa-growing states. Alfalfa honey is of excellent quality and it is most doubtful if the bees ever gather any of it without unwittingly assisting in the fertilization of the alfalfa flower. Where Seed is Grown. — The alfalfa plant has whims and peculiarities not well understood. Parts of California produce seed, other parts are said to make too little seed to be worth troubling with. Nevada is a good seed-producing region, perhaps because of the extreme dryness of the state. Utah produces much seed of high quality and Utah is a dry land. Colorado produces good seed, so does Montana in lesser amounts. The Dakotas produce some seed and large amounts are threshed in Nebraska and Kansas. East of the Missouri Eiver little seed is grown; east of the Mississippi River hardly any alfalfa seed is saved. Stray plants in Ohio, on dry banks or along roadsides will load themselves with seed, while fields saved for the seed make not enough to be worth considering. Texas produces a good deal of seed. It has been found 100 ALFALFA FARMING IN AMERICA. that most seed is produced during fairly dry years. The alfalfa grown on high, dry land without irriga- tion seeds best. Large crops are grown by irriga- tion on dry lands, but the irrigation has to be very carefully done not to water the alfalfa too much. When alfalfa is growing rapidly and has abundant moisture, for some reason not well understood it does not produce seed; the blooms fall and growth continues. On the other hand, when moisture is deficient and conditions are much less favorable seed sets abundantly. It is perhaps the old trick of Dame Nature making abundant provision against the extermination of any of her children by provid- ing bloom and fruit and seed whenever the exist- ence of the mother is attacked. Attempts to grow alfalfa seed in any state east of the Missouri Eiver is apt to result in much disap- pointment. The humid climate, the lack perhaps of suitable insects to fertilize, and the attacks of rust that affects the leaves make it a very uncertain crop. There are times, however, during very dry seasons, when thin stands of alfalfa in the eastern states will mature profitable crops of seed. GETTING A STAND OF ALFALFA. When this is read it may be forgotten that the writer for many years has been a contributor to ''The Breeder ^s Gazette/^ an American agricul- tural newspaper. In his work for The Gazette he has answered hundreds of alfalfa inquiries. Some of these have been put in such a way that they re- vealed an intelligent knowledge of the subject in the inquirers, but very many of these questions are mad- dening in the fact that they show so plainly that the seeker for information has almost no knowledge of his own soil or of any fundamental principles governing soil fertility or plant growth. For ex- ample, here is a sample question; many like it are received every season: ''I wish to sow some alfalfa. My land is lightly rolling and slopes to the west. It was sown in oats in 1906, was in corn in 1907.'^ Simply that and nothing more! What an index of the state of agriculture in the United States in this year of grace 1909! Growing alfalfa is not a question of seed or sowing. Sow almost any sort of alfalfa seed, sow at any time of moon or in almost any sort of way and you will succeed, if — ^here is the fatal ''if" — ^your soil is right. Sow with the great- est labor and pains, make incredible effort at preparation and you will fail, if your soil is wrong. Alfalfa growing is a soil question. Get the soil right and it is difficult to fail. It is easier to get a stand of alfalfa than of most common farm crops. (101) 102 ALFALFA FARMING IN AMERICA. There is no mystery about getting a stand of alfalfa. To make that stand succeed once you get it, there's the rub, especially in the eastern states. Drainage. — What are the requirements of the alfalfa plant as regards soil? First, it likes soil to be dry, dry even in a wet time. That is, it ought to be a soil that will not fill up with water and remain waterlogged for many days. Alfalfa loves moisture too, but it must have moisture and air in the soil at the same time. Thus it likes well drained loams, alluvial soil along rivers or creeks (such lands are usually the best drained) or even gravelly soils, so they have also fertility. If naturally well drained lands are not on your farm then you can make the land dry with tiles. It is entirely practicable to drain land naturally wet and ^'crawfishy'' with tiles so that it will grow alfalfa well. The writer has tested this on Woodland Farm where with his brothers he has laid many miles of tile underdrains. In truth not much of Woodland Farm would grow alfalfa before it was under- drained. Now about the heaviest and surest crops grow on land once too wet for alfalfa to grow at all. Drainage, that is the very first essential in alfalfa culture. Let that truth sink in deep. Do not sow al- falfa on a marsh, nor on a waterlogged clay that will stand full of water half the year. An occasional submergence by the overflowing of a stream may do no harm, will do no harm if the submergence comes in cold weather, or if the water is moving. An over- flow of even a week's duration, if the water is mov- GETTING A STAND OF ALFALFA. 103 ing swiftly, will probably do no harm. Even a few hours of stagnant water lying over the land in hot weather may kill the alfalfa. Drain. Drain deep. Drain thoroughly. Alfalfa roots are living things. Alfalfa bacteria are probably destroyed by being under water for a long time. Tiling. — In laying tiles where alfalfa may some day be sown see that they are laid as deep as the nature of the soil will permit. Soils differ much in this respect; sometimes the subsoil is so dense and impervious that water cannot well penetrate it. In such case it is useless to lay tiles deep in it. They will not drain the land any deeper if laid in the hard- pan than if laid just on its surface. Usually, how- ever, one can lay tiles in clay loams and ^' joint clays" much deeper than he has been accustomed to laying them. The extra depth pays largely. Tiles draw water from a much greater distance when laid deep, and plants thrive in proportion as the perma- nent water table is lowered. If the water level in the soil never rises above a depth of 10' from the surface all the better. Alfalfa roots will readily penetrate that distance. Tiles cannot be laid deeper than 4' or 5' with economy, owing to labor cost; if they could, and the soil were permeable enough to let them operate to their full depth, it would be all the better. On Woodland Farm the rule is to lay no tiles at a less depth than 36'' and the standard dep'th where soil is right and outlet can be had is 48''. In early days many drains were laid too shallow; these are often taken up and laid deeper. 104 ALFALFA FARMING IN AMERICA. Deficiency in Soil. — Curiously enough there are many well drained soils in the eastern part of the United States that are admirably adapted to being penetrated by alfalfa roots, yet on which alfalfa does not naturally grow well, if at all. Such soils often are loose, pervious, easily penetrated by roots. They may be of clayey loam order, or have sandy or gravelly nature. On them perhaps grow chestnut trees. Chestnut soils ought usually to be good al- falfa soils. Naturally they are not. By right treat- ment they may be made good. The clue to their reclamation is lime. Soil a Living Thing.^-A soil is a living, drink- ing, breathing thing. If it is truly alive it has in it much air, sufficient water, but that held in suspen- sion as film water only in the earth, not in satura- tion. That is, there is a film of water about each little grain of sand, between each two grains of soil, and between the layers of water is air. The living soil has in it humus, vegetable matter, in greater or less amounts. It has in it bacteria in immense num- bers. It is alive with bacteria. These bacteria are of various kinds and orders. Some are engaged in destroying humus. They break it down and from the nitrogen in the humus make soluble nitrates. These the plants can absorb through their rootlets. Some of these bacteria are able to assimilate the free nitrogen of the air and make it available for plants growing with roots in that soil. These bac- teria exist in all soils probably where there is plenty of humus decaying. Other bacteria there are GETTING A STAND OF ALFALFA. 105 that live on the roots of the clover and other le- guminous plants. Alfalfa has its own special bac- teria that enables it to appropriate the free nitrogen of ithe air. Alfalfa will not thrive, nor even live very long, without these bacteria helping it. It has become used to them, it depends upon them much as the southern people depended upon slave labor in days gone by. And alfalfa-promoting bacteria will not live in all soils. In some soils they are found in myriads after alfalfa has grown there for a little time, as its near relatives melilotus or bur clover. What sort of soils do we find these bacteria to thrive best in when nature has planted them, un- helped by man? What sort of soils are they that produce alfalfa spontaneously! Let us go afield. Natural Seeding of Alfalfa. — ^^The nearest to wild alfalfa that is found in Amer'ica perhaps is in Montana, along the Yellowstone Eiver. There the writer has seen fields sown to timothy grass invaded by the alfalfa plant and gradually crowded out till at last there was a fine stand of luxuriant alfalfa and that without the sowing of one alfalfa seed. Thus it happened: the canal water floated down a few seed and deposited them near the top of the grass field. They grew and established themselves as lusty alfalfa plants. After the timothy grass was mown off the alfalfa went to seed and scattered a circle of self-sown alfalfa seeds about the mother plant. Next year there were many alfalfa plants where there had been only one, and these in turn went to seed. The end was a well set alfalfa field, 106 ALFALFA FARMING IN AMEKICA. with the timothy grass practically crowded out. And on one farm of 160 acres near this spot, at a place close to Billings, Mont., a farmer sold his one year's cutting of alfalfa hay, amounting to 1,000 tons. Now, what was the nature of that soil! And what of the climate! First, the climate did not have very much to do with it. At least there are thousands of counties in the United States with as good climate for alfalfa growing as this special one, though it is true that there is plenty of sun and heat in summer, but an extraordinarily cold winter climate. Water for irrigation was in abundant supply and' never fear of rain to cause blight or spoil haying. The soil, then! This is a semi-arid region and the soils have not for thousands of years been leached by excessive rains. Thus they are filled with all sorts of mineral salts. They are alkaline soils; that is, filled with salts of lime, potash, magnesia and sodium. ■ Some of these salts are injurious to vegeta- tion, at least when present in excess; others are favorable. The one salt in this soil that especially favors alfalfa is carbonate of lime. This exists in great amounts in this soil, probably at least 1%% of this substance being present. One and one-half pounds of carbonate of lime to each hundred pounds of soil ! How much would that mean in an acre! Taking only the top f oo^% to 4% of carbonate of lime in tho'Se soils. This would be equivalent to from 30 to 80 tons of this substance in the top foot of soil of each acre. Coming eastward it is doubtful if any part of Nebraska, Kansas or the Dakotas need lime, except in their eastern portions or in especially sandy parts. It seems certain that the western portions of these states have lime enough already. Southeastern Kan- sas needs lime, so doubtless do parts of Oklahoma and the Indian Territory. Texas has a great diversity of soils. Parts of Texas are tremendously supplied with carbonate of lime. There alfalfa is almost a weed, suffering only from lack of sufficient rainfall. Eastern Texas, on the other hand, needs lime very badly indeed to make alfalfa thrive. Along rivers the alluvial soils are usually well stored with lime. CARBONATE OF LIME. 139 Arkansas needs lime badly, except in her alluvial soils along the Mississippi Eiver. There one sees luxuriant alfalfa grown. Some of the ^'buckshot" soils of Arkansas have in them a great amount of lime carbonate and are destined to be great alfalfa- producing regions. The hill soils and uplands mostly are in need of more lime. There are excep- tional areas of upland that have already sufficient lime native in their soils, but these areas have not yet been accurately defined. Missouri grows alfalfa about in proportion to her lime content. In Pemiscot county along the Missis- sippi Eiver on ''buckshof soil alfalfa grows glori- ously. This soil contains about 1%% of calcium carbonate. Prof. M. F. Miller, of the Missouri Col- lege of Agriculture, reports that where about >4 of 1% of carbonate of lime is in Missouri soils and humus is supplied through use of manures, alfalfa thrives. At this time (1909) it is unknown how much of Iowa would be helped by application of more lime. A letter giving results from Scott County is pre- sented on a preceding page. It is probable that over much of the prairie section of the state a light application, say one ton to three tons per acre of ground limestone, would put the right condition there for proper bacterial life in the soil. That is about all there is to it; lime enough is needed to make the earth swarm with the right sort of bac- teria. Lime enough is needed to correct any toxie principle exhaled from the alfalfa roots. 140 ALFALFA FARMING IN AMERICA. All the region east of the Mississippi River will be helped by use of ground limestone, with the ex- ception of some favored spots where glaciers have already ground the rocks to powder and mixed it through the land. Anywhere that alfalfa fails to thrive after the land has been made dry and fairly rich one may know that carbonate of lime is de- ficient. Especially may one be sure that all soils along the Atlantic seaboard are deficient in car- bonate of lime, and by supplying this lack their capacity for crop production may be immensely increased. The Chemistry of Lime. — In '^The Breeder's Ga- zette'' of July 14, 1909, Dr. Cyril G. Hopkins, agron- omist of the College of Agriculture, University of Illinois, sets forth clearly the chemistry of lime in its relation to soil improvement. I quote his state- ment complete : The use of lime for soil improvement is a subject which is dis- cussed with a great deal of misconception and confusion, due in large part to the erroneous practice of referring to lime as though it were a chemical element. Lime is not an element and consequently is not an element of plant food. It is an alkaline substance and is known in three forms: the carbonate, the oxide and the hydroxide. The carbonate is the natural form found in rocks and soils and it consists of either calcium carbonate, magnesium carbonate or a double com- pound of calcium magnesium carbonate known as magnesian limestone or dolomite. When highly heated these carbonates lose their carbon dioxide as a volatile gas and the oxide or quicklime remains. This substance takes up water either from direct appli- cation or from the moisture of the atmosphere and changes into the form of hydroxide or water-slaked lime. On long exposure to the air the hydroxide will absorb carbon dioxide from the air and give off water, thus reforming the carbonate compound. Thus we may say that calcium carbonate (CaCOs), calcium oxide (CaO) CARBONATE OF LIME. 141 and calcium hydroxide (CaOaHo) are ordinary forms of lime; also that magnesium carbonate (MgCOg), magnesium oxide (MgO) and magnesium hydroxide (MgOoHo) are the correspond- ing magnesium compounds, more or less of which are contained in magnesian limes, of which the most common form is calcium magnesium carbonate CaMg( 003)0. Any of these compounds may be used for neutralizing acids and thus for correcting the acidity of the soil. If it can be kept clearly in mind that these are the substances properly called lime, and that nothing else is lime, much confu- sion can be avoided. However, a compound properly named cal- cium chloride (CaCL) is often called chloride of lime and yet it contains no lime whatever and does not possess the property of lime. In other words, it is not an alkaline substance and has no power to correct the acidity of the soil. It does contain the ele- ment calcium which is also contained in the ordinary forms of lime, but the element calcium is not lime. Now let us turn to the subject of plant food. There are 10 essential elements of plant food and it is true that calcium is one of these elements and that it is required to a greater or less ex- tent by all agricultural plants, but it is not at all essential that calcium as an element of plant food be applied to the soil in any form of lime. It may be applied as calcium sulphate or as calcium phosphate, and it even exists in many soils which are absolutely devoid of lime which are even strongly acid and markedly in need of lime, but which, nevertheless, may contain abundance of cal- cium for plant food in the form of acid calcium silicates. Thus the acid soils of Illinois which require an application of several tons of ground limestone to correct their acidity contain several tons of the element calcium in the plowed soil of an acre. In some cases soils are found which are not only deficient in lime but also deficient in the element calcium and on such soils the application of any of the calcium limes would furnish both lime for correcting soil acidity and the element calcium for plant food. Summary. — Alfalfa is one of the most beautiful, most valuable and most profitable crops in the world. It makes the most hay. The hay is the rich- est and best. It enriches the soil on which it grows. It endures for many years with one sowing. It has redeemed the arid and semi-arid west. It is coming into every state in the Union. 142 ALFALFA FARMING IN AMERICA. Many needless failures in attempts to grow alfalfa have resulted in eastern states. Alfalfa need not be a hard plant to establish. It is hardier than red clover. It withstands any drouth. It withstands cold better than any other clover. In some regions alfalfa seems native to the soil. In other regions all the nursing in the world fails to establish it. Why is this difference? All natural alfalfa countries have the soil filled with carbonate of lime. There may also be other alkalies in it, and sometimes injurious alkalies, but carbonate of lime is the useful thing found. Wherever the soil is well stored with carbonate of lime alfalfa grows like a weed, if other conditions are good. Where the soil is acid no amount of manure will keep alfalfa alive very long. Carbonate of lime is the sort that God put in the soil when He made it. Burned lime is man's at- tempt at improvement. Burned lime may help and may harm. Carbonate of lime, that is, raw ground limestone, never harms soil. It cannot harm soil, use it as freely as you like. One could put on 50 tons to the acre and do the soil no injury. It would merely lie in the soil inert till it was required. Car- bonate of lime is needed to make the bacteria of alfalfa thrive. It is needed to free the soil from poisons that destroy both bacteria and alfalfa. Car- bonate of lime stops waste of fertility, makes vege- table matter into humus, arrests fleeing nitrogen. Ground limestone will make alfalfa grow without fail, if a few other easily met conditions are com- CARBONATE OP LIME. 143 plied with. The amount needed will vary; all soils have already some lime in them. Where there is marked deficiency apply 100 pounds of ground lime- stone to the square rod for alfalfa growing. Always leave a strip unlimed to note the result. Here are the few simple rules needed to assure alfalfa : First, water let out of the soil and air let in by drains. Second, soil made alkaline, not neutral, with ground limestone. Third, soil with some humus in it, preferably from stable manure. Fourth, soil with phosphorus and a little potash, the phosphorus preferably from bone meal or basic slag, though acid phosphate will answer. And use enough of it. Alfalfa feeds heavily on phosphorus. Fifth, good seed mixed with some soil from a good alfalfa field or from a sweet clover patch, sown on a deeply plowed, firm, fine seed bed, any time between April and September. Ground limestone insures vigorous alfalfa. Vig- orous alfalfa is the most energetic soil enricher in the world. When it has stood a few years if it is then plowed and planted to corn the result is simply marvelous. A field well set in productive alfalfa will yield 5 tons to the acre. This is easily worth $10 to $15 per ton, as alfalfa hay is nearly of the same value as a feed as wheat bran. Thus you note that it yields good interest on a valuation of $250 per acre. 144 ALFALFA FARMING IN AMERICA. Common farm lands do not pay well. Invest in limestone, manure, phosphorus, alfalfa seed, make over that $75 land into $250 land and farming will pay you. Visiting a Stone Quarry. — A visit to a limestone quarry is an interesting thing. These thoughts came one day to the writer as he strolled with a company of Ohio State University agricultural stu- dents beside the quarries at Columbus, Ohio. A great mass of limestone rock rises to within a few feet of the surface of the soil. Here the Scioto river, cutting its way through, has eroded a chan- nel, exposing cliffs of limestone; here have come quarry men seeking to mine the rock for building, for road ballast and for grinding to put upon the soil. Upon this scene burst a class of students, eager and curious tO' note everything, like happy children out of school, climbing over the heaps of debris, shouting merry jests and making exclamations of surprise as they note the many curious revelations. Here, by the railroad embankment, newly made, spring up blue grass and white clovers, their roots in the crumbling limestone of the ballast, eloquently telling how waste soils may be restored and covered over with vegetation where lime is. To our left a tangled jungle of old dry weed stalks standing upon heaps of limestone debris, and as we plunge within this jungle we find the weeds are mostly sweet clover, growing huge and lusty, laden last summer with flower and yet bearing seeds. Think of the CARBONATE OF LIME. 145 myriads of bacteria on the roots of this sweet clover, busily soil building, getting this waste land ready for more useful things. Now we stand at the brink of the quarry, a great hole in the ground. Our gray haired teacher asks us if we know what is the most durable of all man's work upon earth, and smilingly he tells us that the most permanent thing that man has ever yet achieved is a hole in the ground. But, think of the human energy required to quarry and cart away these millions of tons of limestone that once filled this excavation ; and think further than that, to the time when this part of the earth was a shallow sea where warm waves rocked endlessly and little shell- fish swam and crawled, and dying one by one, be- queathed their bones to make the limestone that was one day to become this rock; and next, the quarry- men, short, thick, brown men, hugely muscled, pounding away upon the rocks as though they loved it. They too tell the story of lime, for is not the island of Sicily one limestone rock! Yes, and these sturdy peasants tell another story, the story of the vigor that may come from simple living. For cen- turies their food has been macaroni and olive oil, with, let us hope, an orange for dessert, and yet to- day they can in physical energy far surpass the meat-eating American. And what are they doing, these swarthy Italians, with dynamite mightily shat- tering this rock, with steam locomotives dragging it to the crushers, and there dumping it into yawning jaws that mightily bite and chew it until it is shaped 146 ALFALFA FARMING IN AMERICA. for railway ballast or for concrete construction! And here is another machine, more interesting yet, a machine of prophecy, a machine meaning great things to the farmer, for in this machine, so small and apparently insignificant, the rock is ground rapidly into powder and this powder through end- less carriers is loaded into cars, no man's hands touching it after it is first dumped, and from this mill it goes forth by cars to the fields of Ohio. Think what this means; somewhere an old sour clay field refusing to grow clover, refusing to grow anything rich enough to yield profit, sending no boys to col- lege, giving little hope to the owner, and now under one shower of this ground limestone will come the miracle. The sourness will disappear, clover will grow, the bees will hum, the mower will click, the boy will whistle, books will come into the home and magazines, and let us hope some lad from that farm will start to the university. Building Soils to Stay Built. — My father was a firm believer in the idea that a soil could be so en- riched that it would afterward stay rich, that it would gain momentum enough, so to speak, so it would keep on caring for itself afterward. There- fore he would apply manure in large amounts to one spot of land after another, seeking to establish this condition of things. There is much basic truth in his theory and his practice was not far wrong. When much manure is worked into sweet soil, a soil well stored with car- bonate of lime, there is set up there a laboratory CARBONATE OF LIME. 147 where fertility is steadily manufactured. There will be air in such a soil and bacteria in enormous abundance, among them the useful bacteria that live upon any sort of decaying humus in the soil and gather nitrogen from the air, the new-found azobac- ter. Thus there is a perpetual fertility-gathering plant established right in the soil. It all depends, after all, on the possession by the soil of a large amount of carbonate of lime. If that is absent the fertility put there in excess of the needs of the plants soon leaches away and is gone. The writer has traveled in lands very deficient in lime, so deficient that the well water was almost as pure as distilled water, and there has noted that not only were the fields incredibly poor, but even such places as barn lots had in them very little richness indeed, though manure had been wasted therein for a century or more. Think how old the world is ! And since the rocks cooled and vegetation started to cover the earth roots have been decaying in the soil and leaves fall- ing thereon with stems and branches and all man- ner of debris. Enough vegetable matter, enough humus-forming material, has fallen to the earth and become buried in the earth nearly everywhere, to make the soil incredibly rich. Instead we commonly find even wild soils rather poor. Why? Because of the lack of carbonate of lime. That is the one thing that can 'Ox fertility and hold it for use in future years. On the old farm at Arlington, near "Washington, it 148 ALFALFA FARMING IN AMERICA. is said that manure enough has been applied since it has been in possession of the United States to cover the soil with a layer several feet deep, and yet the land is of only very moderate fertility. Why 1 Because it is so lacking in carbonate of lime. Coming back to my father's idea that land could be given such an impetus towards fertility and pro- ductiveness that it would ^^keep a-going'' it should be said that it is only a partial truth, after all. Doubtless the nitrogen content of the soil can be maintained. In order to do this leguminous crops should come with somewhat frequent recurrence, since legumes restore nitrogen faster than anything else we know. And alfalfa is the most vigorous ni- trogen gatherer at our command. No one can store a soil with fertility and draw upon it with maize or oats or wheat or timothy grass without rapidly depleting his store. All these things are s'oil rob- bers; they do not create or secrete fertility for the soil. Phosphorus Needed. — Nor can legumes or alfalfa do impossibilities. The mineral elements are pres- ent in fixed amounts. Of potash one may have a great abundance and on many soils need never worry nor concern himself, but phosphorus is usual- ly a thing needed and not in sufficient supply. It must be remembered that plants cannot build their tissues, form their blooms and mature their seeds without using in regular '^ balanced ration" all the elements of plant food. They cannot make use of an excess of nitrogen profitably when phosphorus is in scant CARBONATE OF LIME. 149 supply. Thus on Woodland Farm, whicli is rapidly becoming fertile — nearly as fertile, probably, as it is profitable to make farm land — we find it wise each year to purchase this one element, phosphorus. We put it on when we start alfalfa. We put it on the old alfalfa meadows. It pays largely in increased yield and in increased vigor of the plants. This makes the alfalfa able to resist weeds and rust and all the enemies of it. And once on the farm much of the phosphorus is retained, is used over and over again. When we cut the hay we take up phosphorus, and if we were to sell the hay this would be drained away and lost, but when we feed the hay on the farm, as we try to do with most of our crop, we sell away only as much phosphorus as is contained in the wool and mutton of the lambs and in their bones, and what goes to the manure is pretty care- fully saved and put back on the land. Thus our store increases steadily. MANURES AND HUMUS IN SOIL. I have dwelt so long on the subject of carbonate of lime that I must now take occasion to emphasize that lime is not sufficient plant food. Lime promotes bacterial life and saves plant food and makes it available and helps it accumulate. After one has his soil well filled with carbonate of lime, then he is ready to begin to build it. If nature had filled that soil with carbonate of lime ages ago she would have gone on with the work and stored it with vegetable matter, humus. Then there would be now in that soil nitrogen and bacteria in abundance, and prob- ably abundant phosphorus and potash as well, since phosphorus is nearly always in pretty good supply where carbo^nate of lime is plentiful in the soil. Let us get clearly in mind here that liming is only a step in the soil-building process ; it is the founda- tion of things, as it were. And now again let us re- peat that soils are living things. The productive- ness of the soil is dependent upon the numbers of bacteria found therein. Bacterial life is not abun- dant in soils that are deficient in humus, vegetable matter. Stable Manure Best Source. — The very best source of humus is stable manure. If the reader has fol- lowed the story of Woodland Farm, related in the be- ginning of this book, he will have in mind the great part that manure played in building the alfalfa (150) MANURES AND HUMUS IN SOIL. 151 fields. Early in our experience we learned that wherever we applied a good coat of manure, there we got luxuriant alfalfa. This led us to feed lambs and cattle and to save the manure with care. Later study of the use of manure showed us that there was great waste when manure was let stand in the yard till fall before it was hauled out. Therefore we made practice of drawing it at once to the fields and spreading it nearly as fast as it was made. This practice we yet observe. Manure in the soil does very much more than add fertility. Probably we do not know nearly all that it does. First, doubtless it directly feeds the soil. There is nitrogen in manure, some small amount of potash, and a little more phosphorus, though not nearly so much phosphorus as there should be to make a balanced ration for plants. But manure brings in myriads of bacteria. These bacteria aid plant life and plant growth. Where manure is the special nitrifying bacteria abound. The bacteria too that attach themselves to alfalfa roots and clover abound much more in soils filled with manure. Manure Brings Inoculation. — It is seldom if ever necessary to inoculate land for alfalfa when it has been well enriched with manure. I once saw a field sown to alfalfa in Canada that was so well inocu- lated that in six weeks after the alfalfa was sown the tiny nodules were found on the roots, and this field was the first sown in that neighborhood, nor was it artificially inoculated. It had simply been well manured. In other states I have seen the same 152 ALFALFA FARMING IN AMERICA. curious result. In Iowa on the experiment station farm at Ames a field was sown in alfalfa. All the seed was sown the same day and in no> way was the treatment of one part of the field different from the treatment of any other part, yet there was se- cured a fine stand of thrifty alfalfa on one side of the field and very thin and poor alfalfa on the other side. The explanation seemed to be that on a previ- ous year one side of this field had been manured and sugar beets grown thereon. Yet all the field seemed very fertile and Director C. F. Curtiss thought that planted in corn all of the field was rich enough to grow 80 bushels tO' the acre. But that addition of some stable manure a year or two previously made one side of the field eminently fit for alfalfa, while the other side remained in unprofitable condition so far as alfalfa was concerned. From experience I feel sure that I had rather take a rather poor piece of land, well manured, for alfalfa growing, than a naturally rich piece of land with no manure. In truth some of the heaviest alfalfa I have ever seen grew on Woodland Farm on soil naturally very in- fertile, though well filled with lime, after the field had been well coated with manure, the manure turned under deep and alfalfa sown. One day I was plowing in this self same field when a curious thought came. A flock of black birds was following the plow, hopping eagerly along and keeping up animated discourse, meanwhile busily searching for something. What they were after, of course, was earth worms. The thought then came, MANURES AND HUMUS IN SOIL. 153 '*Wliy, liere is the best indication yet of whether alfalfa will thrive in a field. If the black birds fol- low the plowman it is sure to grow ; if no black birds come let him beware how he sows alfalfa." It is indeed a true indication for all eastern soils; there may be lands in the South and West where the earth worm is not a sure indication. Earth worms thrive only where there is humus in the land. They do a most useful work in opening the soil by means of their tunnels to let in air and let out water. They bury up vegetable matter and promote bacterial life. Where earth worms are the soil is evidently drained, although it may not be drained deep enough. Alfalfa Loves Rich Soils. — The plain truth is that thousands of men all over the eastern states of America have tried to grow alfalfa on land too poor for it. Alfalfa loves fertile soil. In turn it adds greatly to the fertility of any land on which it grows. It is an energetic soil enricher, but it will not en- rich poor soils. That may be a pity, but it is after all in the order of Nature. ^ ' To him who hath shall be given. ' ' One must have fertility in order to trap more fertility. No other available plant will gather so much fertility as the alfalfa plant. A field of it will gather nitrogen largely, the hay may be fed, the manure saved, another field enriched and sown to alfalfa and thus the fertility will spread from the one spot of infection till all the farm is covered. But only by beginning right, by making one field rich and dry and sweet, getting it set in alfalfa. 154 ALFALFA FARMING IN AMERICA. then from the manure of that field spreading to an- other, can a man succeed. It is easy once you get started. The farther you go the faster the work proceeds. I write now of ratlier poor eastern soils. Of course there are soils already so rich in all needed elements of plant food that it is idle to add more. Men owning such soils are more blessed than they probably realize. Soils Devoid of Humus. — Will not alfalfa grow in soils devoid of humus? It is an interesting ques- tion. I feel that it will, under certain conditions. There are desert soils that would seem to be almost devoid of vegetable matter, yet fully charged with mineral salts and in these I have seen the most tre- mendous alfalfa that I have ever seen. Perhaps there was more humus in that gray-colored lime- impregnated alkaline soil than I thought, but it certainly was as hard as brick when dry and of the color of lime mortar. It is sure, however, that in eastern soils humus is most desirable; how indis- pensable it is remains to be worked out. An Example of Farm Practice. — On Woodland Farm t'here is one 60-acre field commonly called the Gill field. It has not long been a part of the farm. The soil was clay, some of it white and some of it black. A part of the field was low and peaty. For many years it had probably not paid the cost of cul- tivation. It had had little or no manure since the forest was cleared away. The first step was to get rid of surplus water and miles of ditches were laid, one of them to give out- MANURES AND HUMUS IN SOIL. 155 let being for some distance 10 to 12 feet deep. The usual depth was 3 to 4 feet. Then a very little stable manure was spread over the field and red clover was sown with beardless spring barley as a nurse crop. With the clover was sown a fertilizer com- posed of tankage and acid phosphate. The barley was cut otf for hay and the clover came on and made a fair growth. It was a good stand and had a healthy look, which no one remembered seeing on this field for many years. The clover was cut for hay and seed, and a trifle more of manure spread over the ground. It is evident that on a 60 acre field one will not strew manure very thickly unless he has access to a very large store, and only the farm barns and feeding yards could be drawn upon. The land was then plowed and planted to corn, making about 55 bushels per acre. Its previous crop had been about 20 bushels. On the corn stubble more manure was spread in 1904 and again the land was sown to clover with a nurse crop of beardless spring barley. This time it was hoped that the field might be dry enough and fertile enough to take al- falfa, so a mixture of alfalfa was put with the clover, about 10 per cent or a little more. Again the barley was made into hay. This time the clover was a glorious success, yield- ing more than double what it had yielded the first year and the alfalfa came in strong for the second cutting. It was vigorous over nearly all the field. In the spring of 1906 the field was again sprinkled somewhat with manure and plowed for corn. The 156 ALFALFA FARMING IN AMERICA. yield that year was about 90 bushels. Again with a light coating of manure it was put in corn. This time the yield was 85 bushels. For the corn crop a dressing of 400 pounds per acre of raw Tennessee rock phosphate was applied. Just what effect this had we do not know, as we left no test strips. It probably was of material benefit, however. Once more a light application of manure was made. In truth the applications of manure were all light except on certain spots of exceptionally poor white clay. The land was plowed again and seeded (in April, 1908), to alfalfa with a nurse crop, as usual, of beardless spring barley. With the seeding was sown fertilizer, plain acid phosphate, analyzing about 16 per cent available phosphoric acid, at the rate of 250 pounds per acre. 1908 proved a very dry summer yet a splendid stand resulted over the whole field. A crop of bar- ley hay was cut and later a light crop of alfalfa hay, probably not quite one ton to the acre. From the window where I sit I look out afield across this very stretch of land. It is (May 5, 1909,) a glorious sight. Aside from a few wet pond holes there is not a square foot of the land that is not covered with green and growing alfalfa plants. That field should make near 5 tons of hay this year. And every year since the manure spreader started over the tiled fields the land has paid well. It is not probable that alfalfa would have made a strong growth on this field without this slow bring- ing-up process. The land was too run down, too de- MANURES AND HUMUS IN SOIL. 157 pleted of Immus. Could more manure have been spared doubtless the field could have been gotten ready for alfalfa earlier, but it was not available, so red clover, which is less exacting, came in first and paved the way. Methods of Using Manure. — ^While there can be no question of the value of manure for alfalfa yet there are several ways of using it, some much more successful than others. It is seldom good practice to apply heavy coats of manure and at once sow al- falfa. The trouble is from the strong growth of weeds and annual grasses that will result and which may in part smother the alfalfa. Manure is often filled with weed seeds, has tendency to rush rapidly all weeds that naturally spring up and these worth- less things outgrow the little alfalfa plants. Weeds may usually be subdued by mowing off the field two or three times during the season, but there is danger in mowing young alfalfa at the wrrong time which sometimes destroys it. Briefly, alfalfa ought not to be cut till little shoots appear on the bases of the stems. These shoots appear as buds which de- velop into new stems. Before these shoots appear it sometimes quite destroys alfalfa to cut it off ; this is especially true the first season of its existence. So one can not mow off weeds till these little shoots come. The writer has more than once seen efforts made to force alfalfa to grow by heavy manuring when what it really needed was liming. The only result was a worse crowding by weeds. It is. very much better to apply a heavy coat of 158 ALFALFA FARMING IN AMERICA. manure and plow it under the preceding year, then plant a crop of corn and keep the crop absolutely clean of weeds and grass so that no seeds will be formed. This gives pretty clean land for alfalfa sowing the succeeding year. Impossible to keep corn land clean, say you? It is neither impossible nor very difficult. On Woodland Farm it has been found that about 5 plowings with two-horse culti- vators followed with two goings through with one- horse garden cultivators of the many shoveled type, kept the corn almost absolutely clean, and men with hoes rapidly completed the work. A good stand of corn greatly helps here. Eradicating Fox-tail Grass. — Fox-tail or pigeon grass (Chaetochloa glauca) is one of the worst ene- mies of alfalfa in all eastern America. It is an an- nual grass that becomes very thick in young mead- ows and sometimes in old ones. Mowing it off does not prevent its going to seed, in fact mowing ij; off only seems to make it grow thicker. It cannot be eradicated by disking in new alfalfa fields. Take it all in all it is the worst pest of alfalfa in the eastern states. Crab grass is next to it, but crab grass does not trouble where there is plenty of lime in the soil, while fox-tail is no respecter of lime or anything else. Fortunately fox-tail has its weak point; its seeds do not live long in the soil but soon germinate there and grow. On Woodland Farm we have kept a corn field absolutely clean for one year, and next season sown the land to alfalfa, with the result that we did MANURES AND HUMUS IN SOIL. 159 not see a single plant of fox-tail on a square rod, and this over a great part of the field. Just destroy the plant absolutely before it seeds during one year and you have it conquered. Gro'wing Humus-making Crops. — Not every farm- er has access to a manure heap. Some have too much land, some have too few animals. Thus many who wish to grow alfalfa desire to grow on the land some crop that will help fill the soil with needed humus. Wliat is available for this purpose! Very much depends here upon the location. Cowpeas. — In Tennessee, and probably in Ken- tucky, the cowpea is a good forerunner of alfalfa. The cowpea has several excellent qualities. If a vigorous growing variety is chosen it covers the soil all over and shades it. This shade promotes the gathering of nitrogen as we have long known. The pea vines smother weeds and so help clean the land. Their roots, abundantly supplied with nodules, gather nitrogen and store it in the soil. After cow- peas the soil is also much more friable than it was before. The vines may be left to lay upon the land, disking them and turning them under, or may be cut off for hay. Certainly one gets more humus to turn them under. In the South a crop of cowpeas may be grown and the land plowed and sown to al- falfa the same year. This is not practicable north of the Ohio River. Morgan found in Tennessee a very great increase in alfalfa yield when it was sown after cowpeas. Turning Under Green Cowpeas. — There seems a 160 ALFALFA FARMING IN AMERICA. somewhat greater danger of souring land when green crops are turned under than when they are left to ripen and decay somewhat on the surface be- fore being turned under. It is not easy to accouiit for this fact. It is always well when turning under cover crops where alfalfa is to be sawn to use a larger application of lime than one otherwise would use, since thus he avoids the danger of souring the land. Cowpeas however, may do soils good and may pos- sibly do them harm. It has been taught that cow- peas always build soil, whether the vines are taken away or left on the soil to be turned under. Prof. C. A. Mooers of the Tennessee Station has shown that cowpeas when cut and removed from the soil have a marked effect in depleting it . of fertility. Probably they rob it rapidly of available phos- phorus. It is plain that when cowpeas are grown to prepare the land for alfalfa seeding they ought to be turned under, not taten away from the land. *'Cut them and put the manure backT' Yes, but would it come back! The Soy Bean. — An easier crop to grow than the cowpea is the soy bean, and it also is a soil enricher and affords much humus when turned under. Soy beans are of many sorts. The large growing kinds, like the Mammoth Yellow, make the most vegetation for turning under, while smaller growing sorts make most seed in northern latitudes. Soy beans to do well need soil inoculation. It will come of itself if they are continuously grown on the same land. Soy MANURES AND HUMUS IN SOIL. 161 beans are drilled in drills about 24 inches apart and cultivated carefully till they cover the land, when their shade suppresses weeds. To get a money crop out of soy beans and yet have a hot of humus-making material is easy. One does it with hogs, turning them in after the bean crop is mature and letting them harvest the beans. Afterward the stems remaining with many leaves will be plowed down. Soy beans respond well to fertilization with phos- phatic fertilizers. The larger grows the soil-build- ing crop, whether of soy beans, cowpeas, crimson clover or anything else, the larger the alfalfa will grow after it. Therefore fertilizer applied to the cover crop is all to the good. Crimson Clover {Trifolium incarnatum) . — One of the most charmingly beautiful clovers is crimson clover, the trifolium of the English farmer. It is an annual clover. Sown in summer it makes a fall and winter growth (if there is any open weather) blooms in May, ripens its seed and dies. It is of no use sown in the spring. It is much used in Eng- land, France and the Middle Atlantic States of America. It is a good forerunner of alfalfa. This plant is remarkably cold-resistant and in suitable soils grows during every warm spell of winter. It enriches soils admirably if it has itself the right bacteria at work on its roots. On some soils where it is new it needs inoculation. Crimson clover is sown in late summer or early fall, usually as a catch crop after corn or garden truck. It makes 162 ALFALFA FARMING IN AMERICA. rapid growth during the late season and starts early in spring. It is easily established if sown in late July or August. It will not endure heat so is of no use sown in the spring. It grows during cool weather. On the other hand it will not endure extremely cold weather, and is usually killed by repeated freez- ing and thawing of spring in the region of the corn- belt. It is especially at home in Maryland, Dela- ware, New Jersey, Virginia, and in fact all along the Atlantic seaboard. There it is an admirable catch crop and forerunner of alfalfa when one is desirous of bringing in large areas to meadow with least possible delay. Eoberts shows that the fall growth of crimson clover in New York, taken on Nov. 2, yielded as much as 155 lbs. of nitrogen per acre and doubt- less the spring growth would have yielded in ad- dition even a greater amount had not the plants killed out during the freezes of spring. Nitrogen is difficult to buy for less than 15 cents per pound and often costs much more, so it is clear that the crim- son clover had done a lot of work at nitrogen-gath- ering very economically indeed. Using Crimson Clover. — A good way to use crim- son clover is to sow it in the corn at last working, or to disk up an oat or wheat stubble and sow it there. The latter way will give sure results. Use phosphorus in some form to stimulate the crimson clover, since the better it thrives the more it will do for you and all will be kept in the soil for the I MANURES AND HUMUS IN SOIL. 163 use of the succeeding alfalfa in any case. Acid plios- pliate works well with crimson clover; put on 200 pounds of it per acre, choosing always a grade analyzing a good percentage of available phosphoric acid. It likes a good seed bed too. Mix with it 10 per cent of alfalfa, and if the land has never had on it either alfalfa or crimson clover, get some infected earth from an old field of each of the plants. Infecting a Field. — One can use rather a small amount of earth and get good results in inoculat- ing a field if he does it in the right manner. Let him get as little as 100 pounds of earth from where crimson clover has been grown and 50 pounds of earth from an alfalfa field or a sweet clover patch and mix these together and pulverize them well. Do this away from the sun. Then mix the crimson clover seed, say 15 pounds and say 2 pounds of alfalfa seed with the 150 pounds of infected soil. Sow this altogether on an acre of land. Sow it if you can late in the day, or at any event follow the sower with a harrow that will at once stir the land and cover seed and infected soil. Sunlight is fatal to inoculation. The result will be that both sorts of plants will grow well together and the alfalfa plants, while much more feeble in growth than the crimson clover, will yet hold its own pretty bravely and will be- come inoculated and thus will prepare the land for a single seeding of alfalfa next year. Crimson Clover for Pasture and Hay.^ — The crim- son clover will make good pasture in the fall and 164 ALFALFA FARMING IN AMERICA. early spring. Do not pasture it much if you wish the full benefit of its nitrogen-gathering and humus- making. Before the seed forms, and as early as it flowers, it can he made into hay. Crimson clover hay is nutritious, only when cut too late it has a bad habit of sometimes killing animals by forming hair balls in their stomachs, so it is best to let it ripen and take off a crop of seed, putting the straw back, or else to plow it under and use all the growth as a manure. Do not expect crimson clover to do much without inoculation. This comes in more easily with crimson clover than with most other legumes. Alfalfa FoUoiving Crimson Clover, — As soon as the crimson clover is turned under begin cultiva- tion of the land and get it in fine tilth, destroying any weeds that may spring up. Do not sow the alfalfa seed till the soil is well stored with moisture. After every rain go over the field with some efficient sort of harrow. If the land is not hard a spike tooth drag harrow is one of the best implements of summer culture. Should rain make it hard and in danger of baking, the disk or spring tooth may be needed. The lime may be put on now, though it would have been better to have put it on before the crim- son clover was sown so that it could be doing its quiet work of sweetening the land. As soon as the land is stored with moisture, say by the last week in July or some time in August, the alfalfa may be sown alone. One ought to ob- MANURES AND HUMUS IN SOII.. 165 serve carefully tlie scattered alfalfa plants that grew in the crimson clover to see if tliey were in- oculated, so as to know whether to do anything further toward inoculation of the land before sow- ing to alfalfa alone. Nodules on the Roots. — If he finds the alfalfa plants vigorous, of thrifty growth and dark green color, he may make a good guess that they are safely inoculated. If they are feeble, pale, spindling, yel- low, he may well doubt the inoculation having ^^aken." To make sure let him very carefully dig up alfalfa plants and wash off the earth from their finer root hairs. The nodules are easily seen when present, though one can seldom get them by pulling up a plant, since they are so easily stripped off, their attachment to the roots being delicate. They are of light color, about the size of alfalfa seeds or a little smaller and are sometimes, when conditions are good and lime is plentiful in the soil, set on like bunches of grapes, though usually they are found singly on the little root hairs. Crimson Cloven' in Conclusion. — Crimson clover is a plant better adapted to cool weather than to hot, to England and France, where it thrives, than to regions where grows the royal maize plant. In Eng- land it is termed trifolium and is highly esteemed for soiling in May. It thrives best in sandy soils along the Atlantic seaboard and will probably never be of much importance west of the Allegheny Moun- tains or north of the Ohio River. But in Virginia it is a great aid in getting alfalfa set on old fields 166 ALFALFA FARMING IN AMERICA. needing humns sadly. It has failed in countless in- stances because of lack of inoculation. If one wishes to grow it he should either inoculate with soil from some successful crimson clover field or should per- sist year after year in growing it on the same soil till at last the inoculation comes. There seems a wild clover along the Atlantic Coast that carries the same bacteria, as crimson clover but this is not found west of the Alleghenies. With proper inocu- lation crimson clover will succeed over a far wider territory than is now known or supposed. Melilotus or Sweet Clover. — What is a weed? A plant out of place? Weeds there are and weeds. It one must have them, and usually he will, he could hardly have a better one than Melilotus alba, or white sweet clover. There are two sorts of sweet clover, one with white blooms and one with yellow. The yellow-flowered sort is Melilotus officinalis. It is not so good as the white nor so common. Sweet clover looks like alfalfa. Indeed, it is a sort of first cousin to the alfalfa plant. The main difference is that it has a less deeply boring root stock and is a biennial, or a two-year plant, while alfalfa may live half a century. Sweet clover is a good sort of weed, because it is not unsightly and it feeds the bees and wherever it grows it mightily enriches land. It loves lime land and hard places along roadsides and on railway embankments. It will grow 6 or 8 feet high in favorable places or if it is cut down close it will bear seed when only just above the earth. It was Dr. Cyril G. Hopkins who first called at- MANURES AND HUMUS IN SOIL. 167 tention to the fact that alfalfa and sweet clover bear the same bacteria on their rootlets and that sweet clover inoculates land for alfalfa. (Breeder's Gazette, Sept. 16, 1903.) So there is quite a use- ful combination of facts. Sweet clover is very hardy, it will grow on poor soil, it enriches soil very much and it improves the physical condition of soils, then it inoculates the land for alfalfa. In truth many fine fields of alfalfa have had their start from inoculation taken from sweet clover weed patches along roadsides. Melilotus has never been treated as a farm crop in the Northo In the South it is much used in Alabama and Mississippi, both as pasture and for hay. No better authority on melilo>tus could be found than Prof. J. F. Duggar, Director of the Alabama ex- periment station. I quote from a letter from him: In reply to your request, I give you the following data on Melilotus alba (sweet clover), as it is grown in the central prairie belt of Alabama and Mississippi. The seed should be sown in February and lightly covered. It may be sown either on ground devoted entirely to this crop or sown with seed oats or among growing plants of fall-sown oats. At least one bushel of unhulled seed per acre is needed. If sown alone and on good land there will usually be one or two cuttings the first year. If sown with oats as a nurse crop and on poor land, the first year's growth will scarcely be sufficient for cut- ting, but will afford a fair amount of pasturage. The second year new shoots spring from the old crowns early in March and the first cuttings of hay can be made early in May. There is usually a second cutting. Melilotus should be cut when just beginning to bloom, since after this date it rapdly becomes woody. The hay, especially that secured the year the seed are sown, is very nutritious, the composition resembling that of alfalfa, though melilotus hay contains a smaller proportion of leaves, and the stems are coarser, especially in the hay secured the second year of the plant's life. At first live stock do not 168 ALFALFA FARMING IN AMERICA. relish either the hay or the green plant, but in time most ani- mals eat both with apparent relish, though always preferring grass and other legumes. Sweet clover seeds abundantly in its second year of growth and will thus occupy the land continuously if not destroyed by cultivation. It never makes a full stand except on lime land. Soil deficient in lime, but made up largely of clay, often pro- duces individual plants of thrifty growth, but I have never seen on such land a stand thick enough to be profitable. The chief value of melilotus is for the renovation of the stiff, waxy, lime soils of the central prairie regions of Alabama and Mississippi where the subsoil is a soft or rotten limestone. In Alabama yellow melilotus is not at all comparable in value with white melilotus. The yellow comes up earlier in winter, blooms in April, and is dead by June. It never attains the size of either top or root attained by sweet clover and hence is not equal as a renovating plant. Moreover, the bitter principle is much stronger in yellow melilotus, so strong indeed as to taint the milk and butter made from it, a condition that rarely if ever occurs with white meli- lotus. Note the curious fact that sweet clover like alfalfa revels in lime land. I have seen it growing with great luxuriance in piles of crushed limestone rail- way ballast where one would hardly think any plant could find sustenance, but that railway ballast was of limestone and full of limestone dust. Use of Siveet Clover. — Here would seem to be the correct use of melilotus, for making land ready for alfalfa. If it is land deficient in lime put on ground limestone enough to make it alkaline, or else use burned lime if the ground limestone can not be had. Then in case the land needs humus and fertility to be made ready for alfalfa, sow to melilotus for two years. There is no magic about melilotus probably aside from the magic of its bacteria, and it will grow the better for fertilization, so fertilize it with MANURES AND HUMUS IN SOIL. 169 an application of about 250 pounds per acre of high grade acid phosphate or some better phosphate car- rier. Inoculate the seed when it is sown. That is easily done if one can get earth from some alfalfa field or some sweet clover patch. Not much earth is needed; 100 pounds of earth is ample for an acre. Dry the earth in the shade, spreading it out on the barn floor, and shoveling it over now and then, mak- ing it fine. Mix the earth with the melilotus seed and sow together. Melilotus seed is sometimes seen in the hull, though seedsmen usually sell the cleaned seed. It resembles alfalfa seed almost ex- actly, being sometimes a trifle larger. It weighs 60 pounds to the bushel cleaned. To sow 15 pounds per acre of cleaned seed would doubtless give a stand. Mix this with the 100 pounds of inoculated soil and sow together, for thin land long run with- out manure, land too poor for alfalfa. If it is rich soil one would best sow alfalfa at once and be done with it, but if the soil needs building first, probably the sweet clover plant is as good a thing as oue can build with. It is especially adapted to worn soils (after liming or naturally filled with lime) in south- ern states. No Fear of Pest. — Some fear may be entertained lest the sweet clover becomes a pest in the land. There is no danger of that. Simply mowing the plant will destroy it as it is a biennial and must seed every second year. It often appears in alfalfa fields the first and second years after starting and sometimes the seedsmen are harshly criticised for 170 ALFALFA FARMING IN AMERICA. selling adulterated alfalfa seed. Nearly all western seed will contain a little sweet clover seed and no seedsman probably can detect it or clean it out. It is not a serious injury to the alfalfa and disappears completely the third year when the alfalfa is mown off in regular rotation. There is never any difficulty in getting rid of melilotus when one gets ready to dispose of it. It is very much hardier than alfalfa and probably a better forager for plant food; cer- tainly it thrives on poorer soil than alfalfa does and it does very much to maJ^e the land ready for alfalfa wherever it grows. It does not ask for as deeply drained land as does alfalfa. On the other hand animals usually scorn to eat it, though I have seen it eaten with relish by sheep, pigs and cows in Alabama, and the animals throve. The seed usually sells a little cheaper than alfalfa. Should there develop much demand for it there would be large profit in producing seed on suitable soil, since it seeds very freely almost anywhere, while alfalfa does not. Melilotus in Kentucky. — As indicative of what melilotus is doing in Kentucky we quote the follow- ing extracts from letters written by J. T. Mardis, from Pendleton County: As an illustration of its value, I will explain that seventeen years ago I bought one hundred acres of as badly worn and washed land as could be found anywhere. My first resolve and constant efforts following was to improve and get in grass, and to obtain these results I worked all my spare time, year after year, filling washes with any material to be had, plowing, harrowing and sowing grass seeds and seeds of many different plants advertised and recommended for improving land, for which MANURES AND HUMUS IN SOIL. 171 I spent hundreds of dollars, but as the land was too poor to take in grass to do any good, the labor and seed were lost, as the condition of the land grew worse with each season until seven years ago, when I took up sweet clover, with the result that to- day the land is in fine shape, either being cultivated and produc- ing good crops or in fine blue grass sod, and while producing this effect the land yielded an abundance of pasture and hay. And oh, what a relief to be rid of the sight of those unsightly barren and washed hillsides. It is a biennial, makes fine pasture the first season and abundant crop of pasture, hay or seed the second season. There are two varieties — white and yellow — the latter being generally preferred for hay, as it does not grow so coarse; it grows from two to four feet high, while the white will double this growth under same conditions, and makes splendid hay if properly man- aged; makes more and later pasture and builds land up much quicker. Each is good for all kinds of stock; does not bloat cattle or sheep; is one of the best honey plants known. It is a leguminous plant, the strongest within our knowledge. When once established it requires no further seeding as it reseeds itself. After it has once seeded, the land may be cultivated two or three years and a good stand follow without reseeding. Sown at any season of the year, you are sure to get enough to secure a catch by waiting and allowing it to seed and spread, but of course it is desirable to get a good stand at once, for which I advise sowing from Dec. 1 to March 1, on top of land without covering. Or if sown later, say to the first of May, it should be harrowed or brushed in. It can be sown with small grain of any kind either in spring or fall. If sown in early fall it should be covered sufficiently deep to prevent germination until spring. Good results are had by sowing on stony washed and barren hills during the winter months without previous preparation of the land, as the seed will be carried down by the frequent freeze and thaw. The seed should never be sown on snow or hard frozen ground, as it is liable to be carried off by following rains. Good blue grass sod can be had in three to four years on this class of land by sowing the two seeds together; all grasses do much better grown with sweet clover. To illustrate the rapidity with which sweet clover is gaining favor, I will state that in 1903 I saved one bushel of seed. In 1904 I saved four bushels of seeds. I wrote articles which were published in the county paper, describing its habits and quali- ties. I continued to recommend it locally and in 1905 saved 172 ALFALFA FARMING IN AMERICA. thirty bushels of seed which were readily taken, and later in the season the demand could not be supplied at any price. As a re- sult hundreds of acres of land in this and in one or two neigh- boring counties, so worn and washed that it was almost worth- less, has been and is being brought back to a state of productive- ness and value. In regard to seed, there seems to be no established market as to prices or number of pounds per bushel. It is sold at all kinds of prices per bushel, the bushels ranging from 14 to 60 pounds per bushel. There is also a vast difference in the quality of the seed, as to how it is cleaned and handled, as it heats very readily even in small bulk, consequently there is much dead seed sold, which fact has discouraged many would-be growers. I recommend the sowing of unhulled seed as a cheaper seed as something else is often substituted for the hulled. It should be cut when the first blooms appear and handled much the same as other clovers, giving a little more sunshine, according to weight of crop. For hay I advise sowing the yellow blossom variety on hand v/here the machine can be run. More feed of fine quality can be had per acre from this plant than any grass I have ever seen. For improving land and for grazing I strongly advise using the white variety. I do not recommend sweet clover for low or wet land. We have recently purchased 200 acres more of the same class of land and will soon have this in the same present condition of the first 100 acres purchased. During the spring of the ex- tremely dry season of 1908 we broke for corn an old timothy meadow where patches of sweet clover had been started, and all during the season, after the corn had started, it was easy to see where the sweet clover had grown, and these spots were the only part of the field where we had any corn which was fairly good, and the rest of the field yielded only fodder of poor quality. Mr. James Thompson, an all-round business man and director of the Pendleton Bank at Falmouth, has purchased a few hun- dred acres of worn out land which he has seeded to sweet clover and is well pleased with the investment and says he knows of no other plant so valuable to those having worn out or washed land. Mr. J. S. Gardner, Kelat, Ky.,. stock buyer and shipper, says: "The fattest sheep and cattle I handle are those from sweet clover pastures." Milch cows fed on sweet clover hay yield an abundance of milk from which is made nice yellow butter. Stock cattle, young horses and mules do well on the hay without grain. MANURES AND HUMUS IN SOIL. 173 Land is just as easily broken after a heavy crop of sweet clover as after common red, if plowed before the seed plants have made too much growth. Seedling plants do not interfere with wheat. The yearling plant is a little in the way of harvest- ing, but does not injure the crop, unless it should be very thick. It will grow just as well on the poorest stony washed limestone land as on the best of soil. The land cannot be too dry and hot for it to succeed. It does prepare land for alfalfa by loosening, enriching and furnishing the necessary bacteria. It is a drouth resisting plant, and continues to grow through the dryest sum- mers, furnishing an abundance of grazing, while other grasses are parched, and remains green until quite hard freezing. Sweet clover is all right on good land, but it is the man with the worn land who needs it most. On dry land such' a thing as an entire failure is out of the question if good seed is sown, no matter at what season of the year, but of course you may expect best re- sults from spring seeding where the seed is covered by any means convenient, or from early winter sowing, when nature will do the covering. When sown for hay I use one bushel of seed to four acres, for grazing or improving land one bushel will be suf- ficient for five or six acres. If sown late in the season and the weather is dry the seed will lay over to the next spring and come all right. Some of the best stands I have ever had were obtained from such conditions. Some of the statements made may seem a little extravagant to those not familiar with the plant, yet there is not a particle of exaggeration. Just imagine a growth from six to eight feet high and so thick a man can scarcely walk through it, being left on the land to enrich it and stop wash and to be followed without cost the next season with a growth of seed plants that will form a dense sod and grow to the height of two to three feet, and this process repeated year after year, and add to this the fact that this plant unquestionably attracts to the soil more than double the amount of nitrogen that red clover will under the most favor- able conditions. Can you then wonder that land is so rapidly im- proved?" In Wyoming. — The Wyoming experiment station reports tliat lambs fed npon sweet clover hay relished it and throve. It was found that they digested it ex- ceedingly well, and that it contained a very large percentage of digestible protein. It is well known 174 ALFALFA FARMING IN AMERICA. that animals usually refuse to eat green sweet clover. It seems that when made into hay, with a little salt added, they relish it. The Wyoming experiment is thus reported: Sweet clover throughout most of the eastern states is consid- ered as a weed and is treated as such. At this altitude, under our peculiar conditions, it is believed by a few that there is a fu- ture for it, since it grows well. It is an alkali-resisting plant and, although it is not palatable to stock in the green condition, yet after it is cured, especially where salt has been added, the stock relish it and thrive well upon it. It is very nutritious, readily digestible, and contains an exceedingly high percentage of crude protein. It is more nutritious when cut at the proper period than many of the other hays. The sweet clover hay used in this experiment was grown on the experiment station farm near Laramie in 1905. It had been in stack for over a year before being used for this experi- ment. It was very rank at the time of cutting and the amount of stems, therefore, very large in proportion to the leaves. The stems had become rather hard and woody. Notwithstanding this, the hay proved to be a very narrow ration, since the nutri- tive ratio was only 1:3.2. The crude fiber did not run as high as would have been expected, being but 24.75 per cent. The experi- ment was begun April 13th and completed April 26th, 1907. Amount fed 3,000 grams Amovint of orts 00 grams Amount of feces (air dry) 1,118 grams ANALYSIS. Water. Ash. Ether extract.

It seems that the great objection to the hay is the flavor and the fact that it becomes woody if it is allowed to ripen. It is believed that there are possibilities for this plant in Wyoming if it is cut at the right time and properly cured and cared for. It grows well and the yields are large. The nutritive ratio is 1:32.2, as found by this experiment, which makes sweet clover a narrower ration than alfalfa. PHOSPHORUS FOR SOILS. Phosphorus is the ^'life^' of the soil. Scientists are not agreed as to the function of phosphorus in the soil^ some contending that as applied it is merely a sort of disinfectant, as it were ; that it de- stroys certain toxic or poisonous conditions hurt- ful to plant life. Certain it is, however, that soils well stored with available phosphorus are produc- tive of the right soTts of useful plants. Soils well stored with phosphorus are rich soils, grow rich plants and make splendid animals. The soils of the central blue-grass region of Kentucky are so rich in phosphorus that the addition of more can not usually be seen in the crop. They are rich too in carbonate of lime and from these soils grow the best grasses in the world, and the horses and cat- tle feeding on these grasses are famed the world around. Soils that are poor and unproductive are usually much helped by applications of additional phos- phorus. Alfalfa especially responds to this element. Basic Slag. — Basic slag has already been men- tioned. It is a refuse left from making steel. Cer- tain ores rich in phosphorus make bad steel unless that element is taken out of them. John W. Pater- son of West Scotland Agricultural College, Glas- gow, in an admirable pamphlet on use of ^* Basic Slag on the Farm," says: The essential constituents of manures are nitrogen, potash (176) PHOSPHORUS FOR SOILS. 177 and phosphoric acid for the sake of the crop, lime for the sake of the land. At the outset of cultivation size of crop will generally be de- termined by the supply of the first three. After a term of years the ability of the soil to respond to fresh applications of artifi- cial manures will largely depend on its holding a sufficiency of lime. The use of most of the ordinary artificial manures involves the washing out of lime into the drains. Thus the application of 1 cwt. sulphate of ammonia will, in ordinary circumstances, cause an ultimate loss of more than its own weight of available lime compounds in the drainage of waters. After a long period of artificial manuring the use of ground lime as a soil corrective has been rapidly gaining prominence in recent years. It is in view of this fact that among all artificial manures basic slag possesses a special interest. While primarily em- ployed as a phosphate, it contains ground lime as an accidental constituent. Bones do not cause waste of available lime com- pounds from the soil. Basic slag actually increases them. All other artificial manures in common use, nitrogenous, phosphatic and potassic, cause a gradual washing away of the lime com- pounds from the land. Manures are applied not because the land is ever actually deficient in nitrogen, potash or phosphoric acid at the time. They are applied rather because the natural supplies of these are in a form unsuitable for absorption by plants. The importance of lime in land is that it hastens the conver- sion of the natural soil constituents into available forms. This effect is exercised on the phosphates, on the potash, but above all on the nitrogen. The general effect of liming on newly broken in land, especially on peats, which are commonly deficient in lime, is sufficient evidence of this. Leguminous crops, including clovers, vetches and beans, do not require nitrogenous manures because they are able to utilize atmospheric nitrogen. Lime greatly strengthens their power to do this, thereby giving larger crops and enriching the land in nitrogen at the same time. Basic slag has the same power part- ly owing to the extra lime which it contains, the effect being usually best seen in the stimulation of clovers in pasture leys. Basic slag is a by-product in the manufacture of steel by the basic process. Pig iron freciuently contains phosphorus, and steel made from this is brittle unless the phosphorus is removed. In the process of manufacture a blast of air is forced through the molten pig iron, whereby the phosphorus in the pig is burned to 178 ALFALFA FARMING IN AMERICA. give phosphoric acid. This acid then unites with lime thrown into the molten metal for the purpose. A phosphate of lime is formed. This rises to the surface of the metal as a fusible slag, and is subsequently poured off and cooled. A dark, brittle, hard mass is obtained, which is capable of extremely fine grinding in roller mills. In 1886, Dr. Hilgenstock showed that basic slag phosphate ex- ists as a hitherto unknown compound of phosphoric acid and lime, viz., a tetra-basic phosphate (CaO^PoOs. Later investiga- tions showed that this phosphate, if only sufficiently ground, passes easily into solution even in very dilute acids. In a sample shaken up with peat and water, 78.8 per cent of its phosphate was dissolved in 14 days. The suitability of basic slag phos- phate for direct absorption by plants v/as thereby demonstrated. The special characteristics of basic slag as a manure are (1) the easy solubility of its phosphate in dilute acid, (2) the pres- ence of free lime giving what is chemically called an alkaline re- action. In both these respects basic slag is superior to bones. Super-phosphate, the other principal source of phosphoric acid, is superior in solubility, being water soluble, but inferior in its general effect upon soils, being deficient in lime. These differ- ences in character of the three manures are seen in their relative effects as crop-producers in carefully conducted experiments. The capacity of leguminous crops to utilize atmospheric nitro- gen renders nitrogenous manures generally unnecessary. For the same reason farm yard manure, which supplies much nitro- gen, can in most cases be better utilized upon some other crop. The most profitable return will in ordinary practice be obtained from a dressing of artificials supplying phosphates, potash and lime. Beans, vetches and peas are all lime-loving crops, and for this reason basic slag is well suited to their requirements. Belonging to the same natural order are sainfoin, lucerne and clover, im- portant forage crops. For these, 5 cwt. basic slag, and 2y2 cwt. kainit in autumn, is recommended as a suitable application, with 3 or 4 cwt. superphosphate, and the same quantity of kainit again in spring. The quantities stated may require to be increased or diminished according to the fertility of the land. While the necessity of applying manures to land under crop is now almost generally recognized, the claims of pasture strangely enough are almost wholly neglected. Recent investiga- tions have shown, however, that this is a mistake. More es- pecially is this the case with the medium and second-class pastures, whicn form such a large proportion of our grazing area, I PHOSPHORUS FOR SOILS. 179 Practically speaking, all such pastures will yield a profitable return to a suitable application of manures, and in some cases the natural yield may be even trebled. Attention was first directed to the improvement of pasture land by Dr. Somerville, while director of the Northumberland County Farm at Cockle Park. His experiments were started in 1897, and the results to date are published in a report by his suc- cessor, Prof. Gilchrist. The plots receiving different manurial treatment are each 3 1-20 acres — three acres being grazed each summer, while the odd fraction is cut for hay. The live-increases of the sheep and the yields of hay are carefully noted during each year, and compared with the unmanured plot. Ten differ- ent systems of manuring were contrasted in the experiments, but the following four only need be referred to, as they were most profitable of the various methods: PLOT. MANURES. Cost of manures. Mutton produced (6 years).

The profit is estimated from the extra mutton produced over and above that on the unmanured plot. It is valued for the purpose at 3%d. per pound, live weight. Basic slag here has proved at once the cheapest and most profitable form of fertilizer on pasture. Its superiority to super- phosphate (Plots 4 and 5) seem to be due to the fact that besides containing easily available phosphate it also contains free lime. Comparison of plots 5 and 8 bears this inference. The land at Cockle Park is stiff clay, and has been under pasture for over thirty years. Basic slag is purchased on its percentage of phosphate of lime. The quality varies from about 20 to 45 per cent phosphate (equal to 9 to 21 per cent phosphoric acid). The higher grades are usually rather cheaper per unit. The unit prices of different samples may be ascertained by dividing the prices per ton by the percentages. Other things being equal, the quality which sup- plies the unit of phosphate at the lowest cost on the farm should be purchased. I devote tliis amount of space to basic slag be- 180 ALFALFA FARMING IN AMERICA. cause I have seen such good effects come from its use in England, and because it did equally well on Woodland Farm. It will never perhaps be cheap enough for use west of the Allegheny Mountains, since it is all imported from England or Germany, but along the Atlantic seaboard it is now probably as cheap a s'ource of phosphoric acid as anything known. With basic slag one gets quite a little lime free of cost, since usually there is about 55% of carbonate of lime in basic slag. It should sell for about $1 per unit; that is, a slag analyzing 1S% phosphoric acid should sell for $18 per ton, when it is about as cheap as any other source of phosphorus with the lime thrown in. In England on old pastures basic slag works miracles. There with the sowing of no seeds at all clovers spring up and cover over the land, almost crowding out the grasses. The lime has sweetened the soil, the phosphorus fed it, the clovers result. Later the decay of clover leaves and stems fill the soil with available nitrogen which in turn feeds the grass. When will we learn in America to feed soils! Other Sources of Phosphorus. — Prof. Alfred Vivian, of the Ohio State University, so clearly and concisely states the composition of phosphatic fer- tilizers in his admirable little book, ''First Prin- ciples of Soil Fertility,'' that we here quate: Phosphoric acid is present in the soil in much smaller quan- tities than potash, and experience shows that it is much more likely to become exhausted. In fact, there are sections of the country where no other fertilizers than those furnishing phos- phoric acid are used, while these are bought in large quantities. PHOSPHORUS FOR SOILS. 181 All this class of fertilizers contains its phosphoric acid in the form of phosphates, i. e., the phosphoric acid is combined with sortie basic substance, which is generally lime. The phosphates may be subdivided into two general classes — the natural and the manufactured phosphates. Natural Phosphates. — There are two general sources of phos- phates — the bones of dead animals, and certain phosphate-contain- ing minerals, which will be briefly considered. Raw bone meal is made by grinding raw bones to a powder, and the finer it is the more valuable the product. This substance contains about 22 per cent of phosphoric acid and 4 per cent of nitrogen. Raw bones contain a small quantity of fat as well and, as this prevents rapid decay of the bone, the phosphoric acid and nitrogen in the meal are somewhat slowly available to the crop. Steamed Bone meal. — ^Most of the bone meal sold at the pres- ent time is made from bones previously steamed to remove the fat and a part of the nitrogen compounds. The fat is used in making soap and the nitrogen in glue and gelatins. Steamed bone contains from 28 to 30 per cent of phosphoric acid and about lYz per cent of nitrogen. The steam^ed bones can be ground to a much finer powder, and the removal of the fat causes them to decay more rapidly, so that they must be considered a more valuable source of phosphoric acid than the raw bones. Mineral Phosphates. — In a number of places rock deposits are found that contain varying percentages of phosphate of lime. These phosphates are usually named after the place where they are obtained, as, Carolina phosphates, Florida phosphates and Tennessee phosphates. These rocks contain from 18 to 32 per cent of phosphoric acid, and differ from the bone products in that they are purely mineral substances and contain no organic matter. Ground into a fino powder, they are sometimes sold un- der the name of floats, but the rock phosphates are used only to a limited extent in the crude condition. Superphosphates or Manufactured Phosphates. — The phos- phoric acid in all of the natural phosphates described is combined with lime in a form that is extremely insoluble in water. In or- der to make the phosphate soluble it is sometimes treated with sulphuric acid, which unites with part of the lime, leaving a phosphate which contains only one-third as much lime as the natural phosphate, and which is soluble in water. The lime and sulphuric acid make a compound which is the same as that found in gypsum or land-plaster. This combination of soluble phos- phate and gypsum, made by treating the natural phosphates with acid, is called by the various names of super-phosphate, soluble 182 ALFALFA FARMING IN AMERICA. phosphate, acid phosphate or acidulated rock. For its manufac- ture the rock phosphates are generally employed, both because they are cheaper and because the organic matter in the bones interferes with the use of sufficient acid to make all the phos- phate soluble. A good sample of super-phosphate or acidulated rock contains about 16 per cent of phosphoric acid in a form that is soluble in water. Sometimes when insufficient acid has been used a part of the soluble phosphate will change into a form in- termediate in solubility between the natural phosphate and the acid phosphate, and the acid phosphate is said to have undergone reversion, and the new compound is called reverted phosphate. The latter product is supposed to be more available to the plant than the insoluble or natural phosphate, hence the soluble and reverted phosphoric acid taken together are known as the avail- able phosphoric acid. In some instances bone meal is treated with a limited amount of sulphuric acid and the product is called acidulated bone. This substance contains a much smaller proportion of its phos- phoric acid in the soluble form than does the rock superphos- phate. When soluble phosphates are added to the soil they soon combine with the mineral matter, and are converted first into the reverted phosphate, and finally into the insoluble form such as is found naturally in the soil. In this way the phosphoric acid is fixed and there is no danger of its being lost by leaching. Relative Value of PJwsphate Fertilizers.— The soluble phos- phate present in the acidulated goods is generally considered the most valuable form of phosphoric acid for use as a fertilizer. At first sight it seems useless to go to the expense of making the phosphate soluble when it is again rendered insoluble by the soil before the plant can make use of it. The real object in mak- ing it soluble is to aid in its distribution in the soil. When an insoluble phosphate is applied it remains where it falls except for the slight distribution it receives by cultivation. In the case of the soluble phosphate, on the other hana, the phosphate dis- solves in the soil water and is widely distributed before it be- comes fixed by the soil. In the former case the roots must go to the phosphate while in the latter the phosphate is carried to the roots. It follows from what has been said that after the soluble phosphate is distributed throughout the soil the indi- vidual particles must be very much smaller than is the case with the insoluble phosphate. There are some soils upon which the superphosphates cannot be used without injury, usually those that are deficient in lime, the superphosphate in. such cases having a tendency to make PHOSPHORUS FOR SOILS. 183 them acid. Indeed it is even asserted that soils containing an abundance of lime in the beginning may be made acid by the continued use of superphosphate if no lime is added. When the natural phosphates alone are considered there is no doubt that the preference should be given to those derived from bones. The organic matter present in the bones decays when it is incorporated with the soil, and this process doubtless causes the phosphate to become more readily available to the plant, while the rock phosphate on the contrary is very slowly decomposed. The degree of fineness to which bone meal or mineral phosphate is ground is of prime importance. Very fine bone meal is much more available than that which is coarser and is always rated at a higher price a ton. Using Floats with Manure. — The use of floats, or finely ground phosphate rock, has not met with general favor, and it probably does not give good results when used alone. Some of the earlier experiments indicate that it has practically no value as a source of phosphoric acid for the plant. Recent investigations at the Ohio and Illinois Experiment Stations show that when floats are added to farm manure it has a very high fertilizing value; in fact the increased crop production in Ohio due to adding the ground rock phosphate to the stall manure was nearly as large as that obtained from the addition of superphosphate. The acid substances produced during the decay of the manure apparently make the phosphoric acid in the rock more available, and it would seem from these experiments that the comparatively in- expensive floats might, partially at least, replace superphosphate if used in connection with the manure. Other experiments have demonstrated that good results can be obtained from the use of ground rock phosphate when plowed under with a green manure crop like clover, but that it is of very little value if used on a soil low in organic matter. In a plot experiment at the Mass- achusetts experiment station two "equal money's worth" of ground Carolina rock and superphosphates were compared. In this case the superphosphate proved superior at first, but v/ithin a few years the plot to which rock phosphate was added gave higher yields. It would seem, on the whole, that the use of floats with manure is worthy of a trial by anyone needing a phosphate fertilizer. Ohio Bulletin 134 recommends that the ground rock be used "as an absorbent in the stable, thus secur- ing an intimate mixture with the manure in its fresh condition." Raw Phosphatic Roch for Alfalfa. — Eaw rock, or floats, the natural Tennessee, South Carolina 184 ALFALFA FARMING IN AMERICA. or Florida phospliatic rock, is tlie basis of tlie fer- tilizer called acid phosphate, or acidulated bone. It is made into acidulated form by the addition of about as much sulphuric acid as is taken of finely ground rock. The raw rock contains a large amount of phos- phorus, but it is not in an available condition to be taken up by plants; at least this is the general supposition. Experiment, however, shows that when the finely ground phosphatic rock is put in contact with decaying organic matter in the soil it does be- come available and plants feed upon it. A given amount of money will purchase about two or three times as much phosphorus in the form of raw rock as it will purchase in the acidulated form. J. F. Jack on his farm in eastern Virginia has given the raw rock a careful test and with very marked results. The rock was applied at varying rates, from 250 pounds per acre to 1,000 pounds per acre. Check strips where no fertilizer was applied were left. The result showed conclusively that the raw phosphate was available and where 1,000 pounds per acre was applied the result was a splen- did growth of alfalfa. Even the application of 400 pounds gave good results, though it is not probable that it would be nearly so permanent. Fully as good results were obtained with the raw rock on this par- ticular soil where a heavy growth of crimson clover had been turned down and about 1,000 pounds per acre of water-slaked lime was used, as was had from raw bone, 400 pounds, or acid phosphate, 400 pounds. PHOSPHORUS FOR SOILS. 185 It is not yet safe to say that upoii all soils tlie result would be the same, but on this particular soil, somewhat acid, with a heavy growth of green clover turned under, there is no mistaking the great saving resulting from the use of the raw rock. Upon this same soil potash seemed to give no noticeable result, nor could be found a strip where was applied nitrate of soda at the rate of 100 pounds per acre. It was indistinguishable, showing that the decaying crimson clover furnished all the available nitrogen needed for the growth of the little alfalfa plants. There was left one plot with no inoculation. The result was most astonishing. Where the land was inoculated with soil evenly spread the alfalfa stood thick and strong, knee high and more. Where no inoculation had been applied it was thin, weak, crowded with weeds, many plants less than 2'' high. Phosphates on Alfalfa. — Even on good land I have found it very profitable to sow some sort of phos- phate with new sown alfalfa. The phosphorus cer- tainly greatly stimulates the little alfalfa plants and makes them hustle to get ahead of the weeds and grass. Thus stronger stands result. Also less seed may be sown to the acre than if no phosphorus is used. The writer and his brother have used on Woodland Farm raw bone meal, acid phosphate and basic slag with about equal reults so far as the eye could see. It is our practice to put on 250 to 400 pounds per acre of 16% acid phosphate when the alfalfa is sown in soils well filled with lime. Acid 186 ALFALFA FARMING IN AMERICA. pliospliate is about the most soluble of tlie plios- p'liatic fertilizers and thus is best for top dressing when there is abundant lime in the soil. When there is suspicion that there may not be lime enough then basic slag or bone meal should be used, unless lime also is applied. Acid phosphate dissolves away a part of the lime in the soil. That is its one bad feature. As has been stated the alfalfa meadows on "Wood- land Farm get an annual dressing of phosphorus young and old alike, and this practice pays well. Fertiliser Distributer. — On Woodland Farm we own a wide and large fertilizer distributer. This machine sows a strip 8' wide and the box holds 1,000 pounds of fertilizer. It simply sows the stuff broad- cast on the surface. There are various types of these machines. The American Seeding Machine Co., Springfield, Ohio, makes one, and another is made by the Peoria Drill and Seeder Co., Peoria, 111. With such a machine a man can go rapidly over his old meadow, or sow his phosphorus over his land preparatory to seeding his alfalfa. Time is the thing hardest to command on most farms in the spring; many would fertilize their meadows if they were not otherwise too busy. With these large wide sowing machines a man can rapidly get over his fields. No one should 'hesitate to buy the fer- tilizer, since a dollar so invested will usually re- turn three or four in the crop of hay. Adding to Fertility. — There is here a striking thought. Since our farms east of the Missouri PHOSPHORUS FOR SOILS. 187 Eiver are nearly all of tliem deficient in phosphorus, if we buy it and use it on alfalfa meadows, then feed the alfalfa hay and put back the manure, we are steadily adding to our capital of fertility; not much is lost, only we sell away in the bones of our cattle, pigs and sheep a part of it and in their flesh and blood a little more. An alfalfa farm may thus become a great laboratory of fertility gathering, provided the crops are fed on the farm. When they are sold off the story is different. Hoiv Much PhospJioriisf — In England it is the custom to apply very large amounts of basic slag to their meadows and pastures far in excess of what the plants can take up, and they seem to get large profit from so doing. There is lack of careful ex- periment to show us what amounts of phosphorus will pay best sown with or on alfalfa. The require- ments of the plant, that is, the amounts actually taken away from the soil, are as follows : 1,000 lbs. of alfalfa hay contains 5 lbs. of phosphoric acid; 4 tons, or 8,000 lbs., would then contain 40 lbs. of phosphoric acid. Two hundred and fifty pounds of 16% acid phosphate would contain that amount, and should make good what was removed from the soil by the 4 tons of hay. That there should be abund- ance in supply the writer advises the use of 300 lbs. annually of 16% acid phosphate, or propor- tional amounts of the stuff, if a different percent- age is bought. Thus if only 10% of available phos- phoric acid is present one would need to use 400 lbs. or more. So it is cheaper and better to use only 188 ALFALFA FARMING IN AMERICA. the high grade fertilizers containing large percent- ages of available phosphoric acid. How Well Will This Pay? — In most of the east- ern United States a 16% acid phosphate can be bought for $14 to $16 per ton. Thus 250 lbs. would cost about $2, and the labor of applying it about 30c. Thus to fertilize an acre costs less than $2.50. The yield of hay will be increased in proportion to the need of phosphorus, but on Woodland Farm it has been as much as 2 tons of hay per acre increase, and thus this additional hay cost us only $1.25 per ton. Could we have afforded to have left this land unfertilized! The plain fact is that farming is, after all, a manufacturing proposition. The land is the fac- tory. Its fertility is the raw material. A man would be thought inconceivably foolish who would through stinginess refuse to keep his factory sup- plied with raw materials, thus letting his machinery work to only half of its capacity. The alfalfa meadow, the corn field, these plants are our ma- chines. Feed them with their required raw ma- terial. POTASH AS A FERTILIZER. Most soils derived from granitic rocks have in them a lot of potash. Most soils in the glaciated area of eastern and central America seems to be quite well supplied with potash. Some sandy soils are deficient, and peaty lands, where once old pond bottoms were, are especially deficient. To grow al- falfa on peat or to grow corn there one mnst use potash. Testing ivith Potash. — As a rule on ordinary up- land clays and clay loams potash seems not to be lacking. Very often where it is applied to such soils no result can be seen. It is wise for each farm- er to make test of this matter for himself. Let him procure a few hundred pounds of muriate of potash and apply it in strips over his fields, marking the ends of the strips so that he can see the result, if there is any. About 200 lbs. per acre of muriate of potash is a moderately heavy application. Wood Ashes. — ^Wood ashes may contain 8% of potash and 2% of phosphoris acid. There is also some lime in them and other minerals in small amounts. Wood ashes have an especially good ac- tion on alfalfa. It is an interesting truth that no one has yet been able to compound a fertilizer that would have the same effect as wood ashes, though the ingre- dients were so mingled that chemically the two mate- rials were nearly identical. Nature has done some- (189) 190 ALFALFA FARMING IN AMERICA. thing with wood ashes that man can not imitate very well. The writer has secured splendid results from use of wood ashes on soils that did not seem to need potash. I advise that all wood ashes be saved with care and whenever there is a saw mill or any other wood-burning furnace nearby the ashes should be secured and applied to alfalfa land. Wood ashes are applied in varying amounts, from 500 lbs. to one ton per acre. PLOWING THE SOIL. Plowing is an ancient art. The height of a land's civilization is very nearly to be measured by the sort of plowing done there. What is plowing for! It turns under loose stubble, trash and vegetation, putting it down into the soil where it may decay and by its decay help set free mineral plant food. It loosens the earth to let air in and this promotes im- portant changes in the soil. It lets the water sink down into the soil, hence plowed lands are moister and will withstand drouth much longer than un- plowed lands. There are certain crops that seems to thrive on shallow plowed soils. Alfalfa, on the other hand, seems to thrive best where the land is plowed deep. In older lands than ours, where agriculture has advanced very far towards a perfect system, deep plowing is much practiced. In France some plow a foot deep and even deeper. On the Island of Guernsey men often plow a field twice, the first plowing shallow, the second one crossways and go- ing down as far as 16'^ On such lands alfalfa thrives especially well. In France and Algeria men plow for alfalfa full 2C deep. Why Deep Ploiving Suits Alfalfa. — The reason why alfalfa likes the land plowed deep is doubtless because the letting in of air and moisture favors the life of alfalfa-promoting bacteria. These (191) 192 ALFALFA FARMING IN AMERICA. thrive especially well in soils where the air can penetrate easily. The bacteria supply alfalfa with nitrogen. Thns deep plowing is equivalent to feed- ing the alfalfa with extra nitrogen. The heaviest growth of alfalfa that I have ever seen was on the ranch in Utah where I once lived, the plants stand- ing 48'^ high ail over the field and very thicli. The underlying soil there was of loam, interspersed with layers of loose sand and gravel, a soil that was too easily drained, not very fertile, but well filled with lime and other alkalies. With copious irrigation that land produced enormous crops of hay. Deep plowing in a manner imitates such a condi- tion by letting in the air and storing up more mois- ture as well. Of course one must use judgment. If his soil is of poor clay with only a thin skin of vegetable mould on top one dares not bury that deep under the clay and plant maize thereon, but it is probable that he could do it and plant alfalfa with success, especially if the land was well drained and limed. The water-holding power of deeply plowed soil is about double that of unplowed, or shallow plowed soil. This is important when it comes to getting maximum crops of alfalfa hay. The lack of mois- ture is usually the limiting factor in crop yield, a fact not half appreciated as yet. How to Plow Deep. — I have done some experi- menting on a hard clay soil with numerous small round boulders or ^'niggerheads'^ in it in trying to plow deep. It is not an easy task. In this especial PLOWING THE SOIL. 193 soil on Woodland Farm the top soil is rather poor in lime, leached away by the erosion of centuries of rain. Down about W are many limestone peb- bles. Could these be thrown up by the plow the result would be the same as a heavy liming — be better, in truth. How do we know this! By the be- havior of land that has been tile drained. Where the ditches are dug the subsoil is mixed with the top soil — in fact in filling the subsoil is usually left on top — and there will grow the best alfalfa with- out question. Even in a dry year the effect is very marked, the narrow strip of land where the tile ditch stood sending up alfalfa like a ridge, often 12 or more inches taller than the rest of the field. The effect is more marked on a dry year than on a wet one, so it can not be attributed to the effect of underdrainage altogether. We have found that with a large common break- ing plow we could go down 10'' easily enough, if the land was not too moist nor too dry. After that a smaller plow can follow and go 4'' or 5'' deeper. Not much of this last soil will be thrown clear of the furrow, but it will become well mixed through with the top soil. Woodland Farm has only be- gun experimentation along this line, but we are quite well persuaded that by the time the reader sees these lines we will have abundant proof of the great use of this deep plowing. We are ready to advise only in fairly fertile soils, especially if the subsoil has more lime than the surface, a depth of plowing of 12'' or 16" or as deep as you can go. 194 ALFALFA FARMING IN AMERICA. Plowing, like the tariff, is ''a local matter," so each farmer had better test the thing for himself. On his own soil deep plowing may not work so well. It is easily tested on a small scale in any event. Suhsoiling. — A subsoil plow is one that merely runs in the furrow and loosens up the underlying soil. It does not bring any of it up to the surface. Subsoiled land has much greater water-holding ca- pacity than before it was subsoiled. Sometimes this fact is a detriment, if the land is poorly drained. It is difficult to subsoil land that has in it boulders or large stones. Subsoiled land erodes less than other land, because the water sinks readily into the subsoil and there is thus a great reservoir of satu- rated earth which in turn gives moisture to the over- lying soil. In all hilly regions where there is dan- ger of erosion, as in east Tennessee, subsoiling has been found to be a more useful practice. Not so much work has been done in subsoiling for alfalfa as should be done. I have only done such subsoiling as I described in the ditching work done on Woodland Farm. That has convinced me, however, that some day much land will in some way be loosened up here and tlie yield of alfalfa be increased at least 25%, and probably more. On the Rappahannock Eiver, in Virginia, J. F. Jack has tested subsoiling in a limited way and the result has been very markedly good. In truth sub- soiling tested alongside of additional fertilization gave markedly superior results. Other men have related to me their experiences with subsoiling, but PLOWING THE SOIL. 195 SO far as I am aware nothing has been done in ex- periment station work along this line. On all hard clays and wherever it is desirable that more water be stored in the subsoil I advise the use of the sub- soil plow. It would certainly be wise to test it in a small way at first, then if results seemed good it could be adopted as a part of the regular practice. In Europe it is not unknown to trench or dig up a field with spades to a depth of 36'', mixing top and bottom soils, and land thus treated, well limed, well manured, yields crops that would astonish an American farmer, even if living on the richest soils. Plowing for Spring Solving. — When alfalfa is to be sown in the spring it is well to get the plowing done early, this so that the land will settle together again and make a better seedbed for the seedling plants. Freshly plowed land is too loose to hold moisture near the surface well. Thus it is best to plow for alfalfa in the fall or during the winter. If lime is to be applied it is best to apply it imme- diately after the plowing, or after one dragging of the land. Then it is disked in and mixed well with the soil. If the plowing can not be done early it may be done immediately before seeding, but then more care must be taken to firm the soil again and make a good seedbed. Going over it several times with the disk harrow is one way to firm it, or to roll it with a heavy roller and afterward disking it will bring the top soil into capillary connection with the subsoil. 196 ALFAI.FA FARMING IN AMERICA. It is not SO necessary to get a perfect seedbed in spring sowing as it is when sowing in the fall. There is much more moisture in the spring and heavy rains will probably come to compact the seedbed, yet drouths are to be looked for at any time, so one should do his part well in any case. Example of Spring Sowing. — Take Woodland Farm, where always of recent years seeding has been done early in April. This farm is about on the 40th parallel, in the latitude of Columbus, 0., Phila- delphia and Springfield, 111. Spring seeding is done here because of the climate and soil. Singularly enough at this point on the curve of the earth there seems more fighting of the elements than either north or south of us. At Wooster, 0., some 80 miles north of us, snow and frozen ground prevail during a much longer time in winter than with us. Thus at Wooster they find fall seeding of alfalfa a better thing than spring seeding, while we have had very poor success indeed with fall seeding, which usually lifts out of the ground during the repeated freezes and thaws of winter. Disk, Harrotv and Drag.— hand destined for al- falfa is almost always planted to corn the year be- fore and given very clean and careful cultivation. For the corn crop as much manure as was available was applied. The land is plowed in the fall or win- ter if there is time and the soil is found fit. The plows are set to run as deep as practicable. In this practice we are reforming steadily year by year, deepening our soil as fast as we well cam As soon PLOWING THE SOIL. 197 as danger of hard freezing is over, say by April 10, when the land is dry enough to be fit to till, we go afield with disk harrows. The cutaway double disk harrows suit us very well for this purpose. Fol- lowing the disk harrow goes the slant-tooth smooth- ing harrow, which levels the land quite well. After the smoothing harrow goes the plank drag. This makes a smooth surface, free from clods. The drag is made of three planks, about 2x12, lapped together like shingles and bolted together. The drag makes drilling easier and a better seed-bed. Sometimes the fertilizer is sown before the land is dragged, sometimes afterward. This point is not very material. As already described, we commonly sow acid phosphate of about 16 per cent grade, be- cause it is cheaper with us than bone meal or any other carrier of phosphorus. We sow no potash except on black peaty soils, once beds of swamps. Lime we have applied earlier; it is best to have it incorporated with the soil some weeks or even months before sowing the seed when this is pos- sible. Seeding with Brill. — After the drag comes the drill. We use a drill with grass seed attachment that sows both barley and alfalfa seed. The alfalfa seed is sometimes set to fall in front of the drill and sometimes to fall behind, depending somewhat on the nature of the soil. On stiff clay land it will not do to bury alfalfa seed very deep. On lighter looser soils they will come up through an inch of soil. 198 ALFALFA FARMING IN AMERICA. The drill is set to sow two bushels of beardless spring barley to the acre. This barley does not stool heavily. It is not a very prolific barley either, but it makes a good nurse crop for alfalfa. The facts that it does not often lodge and does not much shade the young alfalfa are all in its favor. SEEDING AND GUTTING. About 15 pounds of alfalfa seed are sown. We have used more and have used as little as 8 pounds. In the long run there seems little difference in the yield of hay, but on the whole we prefer to use 15 pounds of seed. Work After Seeding. — If the land is very dry, we follow the drill with a roller. We seldom do this, however, since there is always danger that rain may follow and further compact the land, making it hard for seeds to get up. We very much prefer to get the under part of the seedbed firm before putting on the seed. We sometimes follow the drill with the plank drag again. We aim always to leave the land quite level and smooth, so that the mower will run nicely. Inoculation. — With us no inoculation is needed, nor was it ever needed seriously on Woodland Farm. Just why this was true we can not imagine except that our father had allowed some few clumps of melilotus to grow and that he had always used a good deal of manure. For some unexplained rea- son manured land is nearly always inoculated with alfalfa bacteria, illogical as the statement seems. Inoculation comes in about a month, little nodules by that time appearing on nearly every rootlet. Further Treatment. — It is seen how easily we (199) ,200 ALFALFA FARMING IN AMERICA. SOW alfalfa, with what slight labor and expense, yet magnificent stands are secured in every instance We have not one record of failure where this system has been followed on Woodland Farm except in a few spots where the barley lodged badly and was not soon enough removed. The further treatment of the field is to let it alone till the barley comes into bloom. Then we go in with mowers and cut it all down and make it into hay. By that time the alfalfa will be needing a clipping. Sometimes we wait till the grain is be- ginning to form in the heads, but usually we take off the barley hay earlier than that. Time to Cut. — The test of when young alfalfa is ready to clip is when the plants put out little buds or shoots down near the ground, at the bases of the stems. It ought never to be clipped before then. After that time it ought to be clipped promptly, as one must not cut off these new shoots with the mower. We have said this before and will repeat it again as the point is so essential to success. Why Make Barley Eayf — Why do we not let the barley ripen its grain! Because if we were to do that it. would seriously weaken the young alfalfa. Eipening grain takes a tremendous amount of moisture from the ground. It also not infrequently lodges and this smothers out the young alfalfa Very little shading or mulching will kill it. So it is better to make hay of the barley. It makes good hay; all animals love it. It is more profitable made into hay than used in any other form. BARLEY AS A NURSE CROP FOR ALFALFA. SEEDING AND CUTTING. 201 Subsequent Cuttings. — Wlien tlie barley is taken away the alfalfa comes vigorously on and makes another cutting in about 40 or 50 days. The time to cut this is judged by the buds or shoots upon the stems, just as at the first. This is in fact the inviolable rule in cutting alfalfa if you wo-uld pre- serve its vigor and productiveness. After this cutting it is left strictly alone. No one trespasses again on the alfalfa, no animals graze it, no mower invades its domain. It may be 24 inches high when killing frosts come; no matter; leave it stand and next year you will gain all that and much more with it. Value of Barley Nurse Crops. — Why the nurse crop with spring sowings'? First, because there is pretty good profit in beardless barley hay. We feed it to all our animals. The alfalfa has grown about as well for the presence of the barley as it would have grown alone. And the barley rather subdues other annual grasses. There is a curious principle in Nature that some plants are delete- rious to other plants. Cockle burrs, for instance, poison land for corn, and where barley grows well foxtail grass is not so much seen. Then when the barley is taken away the alfalfa seems to push right on, almost unmolested. We can get a much better stand of alfalfa with a nurse crop of beardless spring barley than we can to sow it alone, and we get the barley hay as a clear gift. Other Nurse Crops. — Wliy not choose oats as a nurse crop! With us they are not nearly as de- 202 ALFALFA FARMING IN AMERICA. sirable. When oats are left to ripen tlieir grain a poor stand of alfalfa is almost inevitable. I have often sown oats with alfalfa, mowing them for hay when in bloom with good results c When oats are sown no more than a bushel of seed should be sown to the acre. If the soil is very rich and the seedbed very good three pecks per acre will be enough seed, or even a less amount. Oats stool much more vigorously than barley and thus thicken up and shade the alfalfa plants too much. Oats must be mown off earlier even than barley to leave good stand of alfalfa. When the little sta- mens begin to hang out from the oat heads then cut for hay at once. Or if the oats should lodge mow immediately and remove from the ground. Oats make more hay than barley, but it is harder to cure. Flax has sometimes been used as a nurse crop for alfalfa with pretty good success. Alfalfa is sown in wheat successfully in some places. It is absolutely necessary that the land be previously inoculated, or that the inoculating earth be put and harrowed in before the alfalfa is sown, or failure will surely result. It is necessary to harrow the wheat and make a fair seedbed so that the alfalfa seed may be covered. On the whole, wheat is not a good nurse crop for alfalfa, since if the soil is rich it is apt to lodge and smother out the baby plants. Oowpeas, soy beans, rape, Canada field peas, all these things have repeatedly been tried with no SEEDING AND CUTTING. 203 success whatever. They shade too much and smother out the alfalfa. Fall rye sown in the spring is advocated by a New Jersey man who used it thus nearly 100 years ago. I have not tested it, but have my suspicions. Alfalfa may be sown with corn at the time of last cultivation in July. Thus sown it makes almost a stand, never quite a perfect stand. The corn robs the land a little too much of moisture to allow the alfalfa to get rightly rooted. There is also a little too much shade. Should alfalfa seed ever become cheap again it would pay to sow it in corn for soil improvement, even if it was turned over next year in late May and again planted to corn. Where Are Nurse Crops Permissible? — In Ohio, Illinois, Indiana and probably Iowa and Missouri a nurse crop may be often as good a thing as it is on Woodland Farm. Much depends upon whether it is intelligently used. To sow grain thickly and to let it ripen on the land may very likely prove most injurious to the alfalfa. If a man knows his failings, if he is too greedy to cut the nurse crop at the right time, or too careless, he had better not sow one at all, but sow the alfalfa alone. West of the Missouri Eiver it is usually too dry to permit the use of a nurse crop. South of the Ohio Eiver it is safer and better to sow alone in the fall or mid-summer with no nurse crop. It is most tempting when one sees a magnificent growth of oats or barley on the land to say, ''I must let that ripen; it is too fine to cut down for hay"; 204 ALFALFA FARMING IN AMERICA. and the letting it ripen will usually damage the alfalfa stand about 25 to 50 per cent. I have re- peatedly asked a lady for a half-cup of tea and never in my life found but one who could give it ! All the rest would fill the cup full. So if the reader is one of the few men who can resolve to cut his nurse crop for hay at the proper time, he should, if he lives in a similar climate to ours, use a nurse crop. Otherwise he should sow alfalfa alone. Fall Seeding of Alfalfa. — There seems a large area where fall seeding is more successful than spring seeding. Where fall seeding succeeds it is the cheaper way. The use of the land is not lost for any appreciable time, and often one gets a full crop of some sort of grain before seeding his alfalfa. Northern Ohio seems adapted to fall or rather mid- summer seeding of alfalfa ; also New York, in parts at least, a good deal of Pennsylvania and much of Maryland, Virginia, Kentucky and Tennessee, In Missouri some practice one way, some another ; Kan- sas and Nebraska seem to get good results from fall, or better, mid-summer seeding. In Iowa summer seeding is advised. The reason why alfalfa usually thrives when sown in mid-summer or early fall is that then there is less crowding by weeds and especially by annual grass. Furthermore, alfalfa is a heat-loving plant and it pushes rapidly forward if the seedbed is good and it gets started in late July or August. It is very essential that the seedbed be good, and no pains should be spared to make it so. SEEDING AND CUTTING. 205 Spring Ploiving and Summer Solving. — Some have practiced spring plowing of the land and after- ward harrowing it after every rain, after every appearance of weed growth, until all the weed seeds are killed, then sowing the alfalfa alone in July. Usually this results in a good stand. The cost is considerable. No return from the land is had at all for one year and the repeated harrowings cost quite a little. It is one of the surest ways, perhaps, of getting alfalfa started in land very foul with grass and weeds. I do not advise this plan except in cases where it is extremely difficult to get a stand. By harrowing well after each rain nearly all of the moisture is conserved. Thus it is a plan well adapted to use in semi-arid regions where it is not easy to establish alfalfa because of lack of moisture in the soil. In such situations the land should be plowed in the fall and disked after each rain or snow fall and all care possible taken to conserve the moisture that falls. After once the land is moist down to a depth of a foot or more and a thoroughly good seedbed is secured then the alfalfa may be sown, though in such situations il is usually well to defer sowing till August. The state of tilth of soil and the amount of available moisture are more important determining factors, however, than the time of year in dry regions, where alfalfa does not heave out by frost in any event. I can not from my own experience recommend this plan of seeding for any states in the cornbelt region, since it is an unnecessary expense and no 206 ALFALFA FARMING IN AMERICA. more successful, so far as I have seen, than several other less costly plans. Seeding After Early Potatoes. — The land may be plowed early and deep, fitted as soon as it is ready to work and planted to potatoes, choosing some very early maturing variety. There is hardly any better plan than this. The potatoes well repay high manur- ing and fertilization. They should have plenty of phosphoric acid given them; in the eastern states it is common to give early potatoes as much as 500 to 1,000 pounds of high grade acid phosphate per acre; potash also usually tells a good tale when applied to potatoes. Thus if the crop is highly fer- tilized there remains a good surplus in the soil available to the alfalfa. The potatoes well repay good cultivation and thus weeds are destroyed and when the potatoes are dug the land is left clean and thoroughly well loosened up. It is an easy matter then to level it off, disk it well and get ready for alfalfa seeding. This can usually be done in July and as soon as the pota- toes are fit to dig and sell they should come out to make room for the alfalfa, the more important crop of the two by odds. Do not plow the potato land. Disk it very thor- oughly, then disk it again. If the soil is too dry to make alfalfa grow, wait for rain before sowing the seed. Should there come a shower, disk again and wait for a rain that will moisten the underlying soil. There is danger in sowing alfalfa seed in the dust, expecting rain to come and bring it forward. SEEDING AND CUTTING. 207 Rain may come, certainly, but often in only sufficient amount to bring the seed up, or merely to germinate it, and underneath there is dust. Thus the seed- lings perish before they can get their rootlets at- tached to the subsoil. So wait till there is moist soil enough not merely to bring up the seeds but to let their rootlets feed and penetrate on down. Inoculation an Aid. — When sowing alfalfa either in July or August one must remember that the time until fall and killing frosts is short, so do all that he can to hurry it forward. Thus it is well if the land has never had alfalfa on it before, nor ever been manured with manure made from feeding alfalfa hay, to inoculate the soil. Inoculation hastens growth in young alfalfa immensely. Soil from a successful alfalfa field, or soil from a patch of mel- ilotus or sweet clover, or soil from where burr clover grew is usually successful in inoculating al- falfa. The various cultures of beneficent bacteria have not worked well in field practice, we regret to say. So take earth from some other field and inoc- ulate the place you expect to put your new sown alfalfa in. There are various ways of distributing this inoculation. If the soil has been thoroughly well limed, or is naturally well stored with carbon- ate of lime, and if it has had some manure, inocula- tion will 'Hake'' in it and go through the field very rapidly, once give it a start. Seeding. — Sow it in any manner most convenient, either through a wheelbarrow seeder or through a drill, taking great care not to drill it in too deep. 208 ALFALFA FARMING IN AMERICA. Go immediately over the land with an efficient har- row, trying to cover the seed one inch deep. It is no harm to apply more fertilizer at the time of sowing this seed. It will only push the young plants the more rapidly forward. In Ohio, Pennsylvania, Indiana, Illinois and other states of like climates this seeding should be done in late July or early August. It is essential to get the plants strongly rooted before winter sets in with its frosts and cold. The stronger the root the less liability to winter killing. Subsequent Treatment, — No clipping, no pastur- ing nor any other treatment should be given the alfalfa this season. Simply let it alone and keep all animals out of it. The only thing that might cause a man to meddle with it would be if he should discover some dodder in the field. This should be destroyed as soon as seen. Pull up the infected plants and burn them. Throw down a little straw on the spot where the dodder has appeared and set it on fire. Dodder is worse than fire to alfalfa. No other weeds will be apt to trouble. If any large, coarse weeds should come up they may be pulled up by hand. There is hardly any better way of starting alfalfa than this if a man has a liking for potatoes. The crop usually pays well for use of the land, and the alfalfa crop comes on strong and is secured at the least possible expense. Summary. — Summarizing the process of sowing alfalfa after potatoes, the essentials are, first, selec- SEEDING AND CUTTING. 209 tion of good dry rich land, witli plenty of lime in it, or else applying liberally of lime before planting. Deep plowing and somewhat high fertilization for the potato crop. Planting as early as practicable of a very early-maturing variety of potatoes. Very careful cultivation that will conserve all possible moisture and destroy the weeds well. Digging as early as possible and immediate prep- aration of the soil for alfalfa. Inoculating when needed with soil from a success- ful alfalfa field or a sweet clover patch and sowing the seed as soon as there is a good seedbed and enough moisture in it. Covering the seed about an inch deep with the harrow. Leaving the alfalfa alone, no matter how high it gets, leaving all the growth to protect it in winter. Fall Seeding After Wheat. — It is often desirable to sow alfalfa after a crop of grain. This is prac- tical enough if the season proves not too dry. Al- falfa best follows a crop of winter grain, since that ripens earlier than spring sown grain. Perhaps the worst defect in the practice of following alfalfa after wheat arises from the fact that if the land is as fertile as it ought to be to grow a heavy crop of alfalfa the wheat is apt to lodge. There are soils, however, so well balanced that they will grow both excellent wheat and heavy crops of afalfa. I have seen in France wheat as high as oxens' backs, yet not lodged at all, growing on alfalfa sod, and destined to grow alfalfa again in the regular rota- tion. 210 ALFALFA FARMING IN AMERICA. Preparation for Crop. — When alfalfa is to follow wheat the land may be well limed in the fall before the wheat is sown, if it is in need of lime. As early as possible the wheat shocks should be taken off and immediately the plow started in the stubble. Now is a dangerous time, since one may so easily lose his moisture and get instead of a seedbed a mass of sunbaked clods that no harrowing will re- duce to fineness. To avoid this each half day what land is plowed should be fitted by use of harrow and drag, or perhaps use of roller, followed at once by harrow. It is not sufficient to fit each evening what has been plowed during the day, but each half day's work must be completed within that half day. This is also much the easier way. An hour spent upon freshly turned land will do more than a half day after the furrows have dried out into hard clods. Be not content, either, with a half preparation of the land. Do a good job of it. Use drag, disk and smoothing harrow. Make the earth fine. Seal up in it all the moisture it holds. It is work well spent. Since it must be done in any event it is wise and economical to do it immediately it is plowed, when an hour's work is worth a half day's later on. In order to do this best it may be well to let the man who does the plowing work till about 9:30 in the morning, then, unhitching from the plow, hitch to the plank drag and go over what he has plowed with that. Unhitching from it, hitch to the disk harrow, and after disking then go over it with the slant-tooth smoothing harrow, which finishes it pretty well and SEEDING AND CUTTING. 211 effectually seals the land so that no moisture can escape. Of course if several teams are plowing one man may follow steadily with tools for fitting the land. Save the moisture. It is wise not to sow the seed before there is plenty of moisture stored. In this connection the reader should study the preced- ing advice upon summer seeding. Save all the moisture you have and accumulate as much more as you possibly can before sowing the seed. And yet one can not safely delay sowing longer than till about the 10th of August, and if it can be sown in a good seedbed with sufficient moisture by the first of August all the better. The time of sowing is a local question. In Louisiana one can safely sow the last of October, yet north of the Ohio River late July and early August sowing is much safer than any later sowing. Inoculation in Advance. — It is well to inoculate the soil for this fall seeding, and the reader is asked to note with care what has been written elsewhere on this subject. One way of getting this inoculation in a wheat stubble is to sow some alfalfa seed in the wheat in March. If 5 pounds are then sown and harrowed in with a sprinkling of inoculating earth, say 100 pounds to the acre, and the soil and seed mixed together, it is probable that a fair growth of alfalfa will result -and the inoculation spread throughout the whole land. Then when the land is plowed again and the young alfalfa turned under the inoculation will be spread. Quite a little benefit 212 ALFALFA FARMING IN AMERICA. will be seen from the fertilizing effect of the young alfalfa turned under. And further one can judge quite well by the growth of this spring sown alfalfa as to the state of fitness of his land, whether maybe it needs more lime, more drainage or further enrich- ing. The cost need not concern you, since with good inoculation present less seed need be sown in the fall. Indeed 15 pounds of seed sown on a good seedbed well inoculated will give a better stand than will 30 pounds sown on a poorly prepared seed- bed or without good inoculation. Ordinarily it is of no use to sow alfalfa seed with the wheat in the fall. It usually perishes during winter. There are soils and climates, however, where it will succeed fairly well thus sown, and by this means good inoculation could be had. Five pounds of seed to the acre with about 100 pounds o.f inoculating earth should be sown then. All in all, to sow after wheat is a good prac- tice wherever fall seeding is desired and a soil-build- ing cover crop is not needed to prepare the land for alfalfa growing. The one danger is that there may not be enough moisture stored to give good fall growth. The alfalfa must not be clipped nor pas- tured the fall it is sown. The next year it is cut three or four times, as would be any ordinary alfalfa field. Alfalfa After Spring Barley. — ^Spring-sown grain has some advantages for alfalfa sowing. For one thing the soil is more easily got ready for alfalfa after the grain is removed. Then these grains are SEEDING AND CUTTING. 218 not SO apt to lodge if the soil is rich. Beardless spring barley is particularly appropriate here. It ripens very early and does not often lodge. It is almost impossible to make the soil too rich for spring bar- ley. It is advisable to plow the land for these spring crops and to plow it deep. It is well always to sow a small amount of alfalfa seed with the barley. If it is the custom to sow 20 pounds of alfalfa seed in the fall it will be much better to sow 5 pounds of this in the spring at time of seeding the barley. This will help the inoculation very much indeed and the 15 pounds sown in the fall will give a better stand than would the whole 20 pounds sown at that time. The same rules laid down for sowing after pota- toes and wheat apply with equal force for sowing after spring barley and should be studied. The one trouble with all this scheme is that it pre- supposes a very fertile soil and quite a little rain- fall in late July and August. Given these things one ought to succeed admirably following this plan. Alfalfa After Oats. — What has been said of seed- ing after barley applies fairly well to oats. The field should be well plowed in spring. Five pounds of alfalfa seed should be sowed to each acre to pro- mote inoculation. If no alfalfa has ever grown on the land and inoculation is doubted, soil should also be spread or sown and promptly harrowed un- der. Then the oats if cut off for hay will leave a far better seedbed than if allowed to ripen. Ripen- ing oats draw tremendously on the soil moisture. It is a great help to mow them off for hay when coming 214 ALFALFA FARMING IN AMERICA. into bloom. Thus the land may be prepared very much earlier for its destined crop of alfalfa. Alfalfa After Crimson Clover. — Where the cli- mate is mild enough to permit its growth crimson clover forms an admirable preparatory crop for fall sown alfalfa. The subject is mentioned in an earlier chapter, but I will here sum up its advantages and manner of use. Crimson clover is an annual. Sown in the late summer it grows during the fall and whenever it can during warm days in winter. It makes very rapid growth in spring, blooms in May, ripens seed and dies. It is not a good clover for for- age unless fed off green. Half ripe crimson clover heads are dangerous when fed to animals, making ^'hair balls'' in their stomachs and killing them some- times. A fairly good crop of crimson clover will yield to the soil as much nitrogen as would cost $15 per acre, if one were to^ purchase it in the bag. It comes off or goes under early enough to make easy the preparation of a good seedbed. There is seldom danger of insufficient moisture when crimson clover is the crop preceding alfalfa, supposing the land to be well managed after the clover is ready to turn under. On the other hand crimson clover does not thrive well without inoculation, and natural inoculation seems absent except along the Atlantic seaboard. Doubtless artificial soil inoculation would result in great gain with this plant elsewhere. Crimson clo- ver provides a great deal of very valuable humus. Mr, Jack's Use of Crimson Clover, — In eastern SEEDING AND CUTTING. 215 Virginia, under the direction of C. V. Piper, J. M. "Westgate and Nicholas Sclimitz of the Department of Agriculture, J. F. Jack is sowing what may be well termed an alfalfa ranch. His estate consists of nearly 2,000 acres along the Eappahannock Eiver, When Mr. Jack took this land much of it was in a most impoverished condition. The land is first iDlowed and planted to corn with 250 pounds per acre of raw bone meal. Sometimes other fertilizers are used. The plowing is deeper and more thorough than the land has ever known before. Next, at last cultivation of corn, crimson clover seed is sown at the rate of about 20 to 30 pounds per acre. A small growing wild hairy clover is found on these fields that probably inoculates the crimson clover and it grows well. In May this crimson clover is knee high all over the fields. Then it is turned under, plowing about 8 inches deep. Lime is put on, either ground limestone at the rate of about 2 to 3 tons per acre or burned lime. Intensive cultivation is given the land till August, the pur- pose being to store the land with as much moisture as possible. Then men come and sow with hand labor inoc- ulating earth. This Mr. Jack can get from his own farm, though originally he had it shipped to him from sweet clover beds along the Potomac Eiver. Immediately behind the men who distribute the earth walk other men with wheelbarrow seeders and distribute alfalfa seed. Behind these men come 216 ALFALFA FARMING IN AMERICA. harrows and almost instantly the seed and inocu- lating earth are covered np. The fertilizer is usu- ally 400 pounds per acre of raw bone meal, though other sources of phosphorus have been used as well. The result is as certain as mathematics. Mr. Jack at Belle Grove gets stands of alfalfa every time, good, thrifty, healthy, profitable alfalfa. It is very notable, however, that wherever Mr. Jack has applied a little manure there he gets much stronger crimson clover and much heavier alfalfa as well. It is not yet proved that a man can build successfully very poor soils without manures. Cer- tainly the work is greatly accelerated when manures are available. I have treated at some length the experiences of Mr. Jack because I know of no more impor- tant work being done anywhere in the east. Here one sees land taken in impoverished condition fairly representing millions of acres of farming lands in the older eastern states, unprofitable to farm, worth- less as an investment unless redeemed, and by appli- cation of plain and well tested agricultural prin- ciples brought rapidly into profitable culture again. Mr. Jack's success, doing this work on a large scale and as a business venture, is a lesson in soil build- ing and business methods in farming of illumining importance to the whole farming world. Rate of Seed per Acre. — There are in a bushel of alfalfa seed about 14,000,000 seeds, more or less, according to their size and weight. Thirty pounds to the acre then would put about 160 seeds to the SEEDING AND CUTTING. 217 square foot — sometliing over one seed to eacli square inch of soil. An alfalfa plant requires about 16 to 25 square inches of space. Thus use of 30 pounds of seed is from 16 to 25 times too much, supposing that each seed dropped made a living plant. When sown in drills one pound of seed is enough for an acre, and seeding in drills will be a practical scheme in America. One pound of seed per acre makes approximately &Ye seeds to each square foot. There ought to be nine plants per square foot to make a good stand on ordinary soil fit for alfalfa growing. That would require two pounds of seed, sown broadcast, if every seed made a plant. The germination of alfalfa seeds is not usually perfect; often with the best seed only about 75 per cent will germinate the first year. And not every seed will be covered right for germination. Thus if we allow half to perish for lack of right planting we will come to a need of four pounds of seed per acre to give an ideally perfect stand. As a matter of fact this amount is often sown. Where one desires to grow alfalfa seed a thin stand is better than a thick stand and four pounds of seed will suffice. Of course one must be sure of his seed- bed and of his seed if he ventures to use so thin a seeding. And he ought to be sure that the land is inoculated. On inoculated soil a thin seeding will give a better stand than a thick seeding will on un- inoculated soil. The Ohio experiment station has made an inter- 218 ALFA"LFA FARMING IN AMERICA. esting test of this very matter and the results are herewith recorded: The Ohio station put out a thick and thin seeding test of alfalfa June 27, 1907, at the rates of 5, 10, 15, 20 and 25 pounds of seed per acre. The seed was distributed through the grass- seeding attachment of an ordinary wheat drill after repeated and careful testing. It was dropped in front of and covered by the drill hoes. The results of this test thus far appear in the following table: THICK AND THIN SEEDING OF ALFALFA. SEED USED PER ACRE. 5 pounds 10 pounds 15 pounds 20 pounds 25 pounds No. plants per sq. foot July 31, 1907. No. plants per sq. foot May 2, 1908. Total pounds hay per acre, 1908 (3 cutting-s). 7,863 8,648 8,678 8,557 7,876 It will be noted that the maximum yield was harvested from the plot receiving 15 pounds of seed per acre, but that 10 pounds of seed gave within 30 pounds of as large a yield of hay per acre. The yield from 20 pounds of seed is somewhat lower than from 10 and 15 pounds, and the yield from 25 pounds decidedly lower, exceeding the yield from 5 pounds by an insignificant amount. It should be stated that 5 pounds of seed per acre proved a little light in so far as holding the weeds in check is concerned. If a few large weeds had not been removed from this plot it would have presented a somewhat ragged appearance. This being done the quality of the alfalfa was as satisfactory as on any plot. This ground was in ideal condition for alfalfa when seeded, having been plowed some eight weeks previous and harrowed at intervals of 10 to 20 days until seeded. Under such conditions 10 to 15 pounds of seed per acre would seem to be enough. It is to be doubted whether more than 15 pounds of alfalfa seed per acre is needed in this state when a good seed bed is prepared, and it is surely cheaper to prepare such a seed bed than to buy alfalfa seed to waste among clods, or in a loose, dried out soil. As a matter of experience extending over many years I advise the use of 15 to 20 pounds of seed for ordinary soils and under ordinary conditions. SEEDING AND CUTTING. 219 While it is true tliat this gives a good many more plants than are needed, yet these will crowd each other out in time and about enough will survive to make an ideal stand. An extra alfalfa plant is simply a weed in the field, but it is the best weed that can be selected, and it undoubtedly deters the growth of other weeds to a greater or less extent. Thick Fall Seeding Wrong. — Men have sown as much as 40 pounds of seed to the acre in the fall. This is a serious error. The plants standing so thick- ly, more than 200 of them to the square foot, so crowd each other that they can not grow as they ought, and so no root gets strong as it should before the winter sets in. The result is that the frost lifts and destroys a large percentage of them all. With half the seed sown and stronger plants more would have been alive in the spring. Curiously enough the better the land is adapted to alfalfa growing the fewer plants an acre of it will carry. I have seen wonderful alfalfa meadows with no more than 40,000 or 50,000 plants to the acre. Each root, however, had many stools and stems, a hundred perhaps or more from the one root. Sowing the Seed. — If the seed is sown on freshly harrowed land it is best. The seedbed should be firm, well worked down, yet freshly stirred. Thus the seed stick wherever they happen to strike and do not roll around or get in bunches. The manner of distribution is not very essential. Perhaps the most even distribution is had by the wheelbarrow seeder. Any of the commercial seed sowers on the market 220 ALFALFA FARMING IN AMERICA. will do good work in capable hands. An end gate broadcast seeder tbat may be attached to any wagon will do good work. It may be sown by hand if the operator understands seed sowing, or it may be sown with a drill, letting the seed fall behind or in front of the hoes, according to circumstances and the con- dition of the ground. The aim is ultimately to cover the seed an inch or about an inch deep. The harrow may follow the sower and finish the covering. Prob- ably for this purpose the common slant-tooth smoothing harrow is the best implement. When seed and inoculating soil are applied together, the drill or fertilizer distributer is the best implement to use. Drilling in the Seed. — The American Seeding Ma- chine Co. has developed a drill that will sow alfalfa seed accurately in rows 6'^ apart, putting it in at any desired depth. I have seen alfalfa sown with one of these machines, with 20 pounds of seed to the acre, that was at least 10 times too thick. It is evident that with a perfect seedbed and a proper alfalfa drill one need sow no more than 5 pounds of seed to the acre. This means a fine seedbed, firm underneath, level and smooth. The saving of seed would pay for all the labor of preparing the seedbed and the resultant thrift of the alfalfa would be very fine to see. This machine will drill in 4 pounds of seed to the acre, and to a required depth. Alfalfa with Bed Clover for Inoculation. — When- ever it is suspected that alfalfa may be adapted to a soil and red clover is to be sown there in the reg- SEEDING AND CUTTING. 221 ular rotation, alfalfa should be mixed with the clover seed. If 10 per cent of alfalfa seed is used it will be enough to give a good sprinkling of alfalfa plants and later a thorough inoculation of the land. How this inoculation comes we do not know. Certain it is that when alfalfa is sown on suitable soil, dry and with lime enough, it becomes inoculated in a year or two by natural means. Thus two things are ac- complished: One gets a good general idea of the suitability of the soil to alfalfa and he gets it in- oculated so that when a little later he sows alfalfa alone it assuredly grows strong from the start. Furthermore, the mixture of red clover and alfalfa is a good mixture anyway. It makes more hay and more pasture than red clover pure. It en- riches the soil more efficiently. Alfalfa is nearly as easily established as red clover. If sown with oats or if the wheat is harrowed to let the seed be covered it is certain to make a pretty good stand mixed in this way. Bed Clover with Alfalfa. — On the other hand, some men practice sowing red clover with alfalfa. They claim that with the addition of about 20 per cent of red clover seed to the alfalfa they get a heav- ier yield of hay the first year following the seeding and the next year pure alfalfa results which outyields adjoining fields or plots that have had no red clover in them. That is, the decay of the red clover roots, they assert, enriches the soil for the alfalfa. This is said of some soils in Pennsylvania. In my own experience this is not a very good practice, since 222 ALFALFA FARMING IN AMERICA. it leaves the alfalfa a little tliin on the ground after the clover has died out, but I have not tried it more than once or twice. Alsike Clover and Alfalfa. — These sow well to- gether and make wonderful forage either for soiling, feeding off for pasturage or for hay. It is best, of course, to call it an alsike field and treat it as though no alfalfa were sown in it, since the alfalfa is much more permanent than the alsike, Alsike, however, is in some soils more permanent than red clover and will sometimes last as long as four or five years. It does not cut more than one, or at most two, crops of hay in a year. Some of the loveliest pasturage the writer has ever seen has been a mixture of alsike clover, alfalfa and smooth brome grass. INOCULATION AND NITROGEN. Many once deep, dark mysteries are now cleared up so that we smile at what once made men despair. Alfalfa growing was once as deep a mystery as any one could name. Sown in Colorado, Utah or Cali- fornia alfalfa thrived from the start almost. Sown in Ohio, Illinois, Kentucky or New York it often failed. When it lived it was for some months or a year or more a feeble, unhappy, sickly plant. After a time perhaps it recovered and made wonderful growth. Why This Difference? — Why should it behave so differently in different regions? Of course there are several answers to this query. One is that some soils are filled with lime and phosphorus, are dry and filled with air. Alfalfa loves such soils. But the other and more hidden and mysterious reason is that of the nitrifying bacteria that help alfalfa grow. These bacteria are naturally present in some soils. They live on more species of legumes than alfalfa alone. Burr clover (Medicago arabica or Medicago denticulata) carries the same inoculation, uses the same bacteria. So does sweet clover or melilotus. Doubtless there are other wild legumes growing in western arid soils that use the same bac- teria. On the other hand, in eastern soils these bac- teria were absent almost altogether. One of the best illustrations of the lack of inoculat- 224 ALFALFA FARMING IN AMERICA. ing bacteria was seen in Christian County, Kentucky. A field of good limestone soil was well enriched and sown to alfalfa in the fall. A fine stand re- sulted and I visited it the next spring, some time early in May. The alfalfa was short, stunted, of yel- low color, clearly destined to be a failure. Careful search revealed no nodules on the roots. One bunch of thrifty alfalfa was in the middle of the field, another at one edge, near where had stood a negro's cabin. I dug up these plants and found abundant inoculation, the nodules being plentiful. I dug out the soil around these spots and threw it over the field. Eains distributed the bacteria still further, so that in a year the whole field was inoculated and yielded a heavy crop of hay, about six tons to the acre. The land had been well limed. Vital Relation of Bacteria. — What is the vital re- lation between bacteria and alfalfa? I make no pretense to exact scientific knowledge on this ques- tion. As near as I understand it the case is about as follows: Alfalfa is a legume. All or nearly all leguminous plants are aided in their growth by bac- teria that associate themselves with. the plants, living on the roots or on the rootlets. With plants using these bacteria existence without them is precarious and often impossible. Securing Nitrogen. — The problem of fertility, of production of plants, of crop yield is a curious one. Some elements going to make up plants are mineral ; these we find in the ash of plants. A large part is water; this comes easily enough from the soil. A INOCULATION AND NITROGEN. 225 large part is carbon; carbon is taken from tlie air by the leaves of the plant. There is plenty of car- bon always for plant growth. There is usually plenty of water. Mineral elements — potash, phos- phorus, lime, iron and so on — are easily enough added to the soil. The sole remaining element is nitrogen. Nitrogen is one of the essential elements in the proteins of food, the albumens. Nitrogen is essential to nearly all life, animal and plant. All the higher animals need much nitrogen in their foods. All the grains have in them much nitrogen. Nearly all crops taken away from the soil remove a great deal of nitrogen. Soil waters leach it away. Since the beginning of the world everything has preyed upon the nitrogen of the soil. The rocks in the be- ginning held little or none of it. Whence did the soils then obtain their nitrogen supply! Tico Classes of Plants.— Tlaere are two classes, very broadly speaking, of plants in the world, the nitrogen gatherers and the nitrogen users. Corn, wheat, the grasses, potatoes, flax, oats, nearly all farm crops use nitrogen and can not get it except as it is already stored for them in the soil. That at least is as far as we know now. At any rate soils grow poor in nitrogen when crops of corn, wheat, hay or almost any crop except clover or some other legume is grown upon it. Certain crops are soil builders. Certain other crops are soil robbers. The legumes are the soil builders. They get nitrogen in some way. How do they do this? Abundant Nitrogen in ^ir,— Nitrogen exists in 226 ALFALFA FARMING IN AMERICA. enormous amounts in the air. Nearly 80% of the air is pure nitrogen. Why can not the leaves take it directly in as they do their carbon from the air I That we do not know, but they can not do it. Plants will starve and perish for nitrogen with their leaves bathed in that substance, with their roots surround- ed with it as well, for in all porous soils there is much air. About Bacteria. — Bacteria do the work. Bacteria are very minute plants, sometimes almost like ani- mals in having some power of motion. Yeast is a bacteria. They are intensely minute. It would take 5,200 of them, placed in a row, to be an inch long. Twenty-seven million could be on a square inch of space. A farmer can not ever hope to see one; it takes a powerful microscope to show one, yet any farmer can see the work they do. It is thought that there is really only one sort of bacteria for all the clovers, but that habit has divided them into varieties, similar yet unable to live on the same plants. Thus there are the red clover bacteria, the cowpea bacteria, the alfalfa bacteria, and many more. Some bacteria live on several different plants, just as the alfalfa bacteria thrive on melilotus, al- falfa and burr clover. These bacteria when they touch a tiny rootlet of alfalfa have power to enter it and abide there. They increase there and swarm in incredible numbers. They are really parasites upon the plant, most like- ly. The plant attacked puts out a protective cover- ing, thus forming a swelling nodule on the little INOCULATION AND NITROGEN. 227 rootlet. This nodule is filled with these bacteria. Nodules are not all alike ; some look like little seeds, some like bunches of grapes. They vary in size and shape very much. Nodules on alfalfa plants are rather smaller usually than alfalfa seeds. They exist only on the root hairs. Evidently these bac- teria prefer the new fresh roots. The Work of Bacteria. — What do the bacteria do for the plant! In some way they digest nitrogen and assimilate it. In some way the plant gets it. How? We do not know that. Maybe they die and decay and the plant absorbs them. Maybe the plant assimilates part of them before they get old enough to die. Anyway we know that they get hold of the nitrogen that exists in the air and that comes down into the soil through its pores, get hold of it, use it and give it to the plants. That is the miracle that lets life exist on this world of ours. A happy chance 1 Yes, or a thought of God. It is certain that were it not for this ^^ chance," human life, and animal life as well, would ultimately perish from the face of the earth. On such tiny beings as these bacteria does all life on the world hang for its ultimate existence. Thoughtful men have long felt alarm over the state of the world as far as the food supply of the people was concerned, all because of this very drain of nitro- gen from the soils by crop growing. Dr. Cyril G-. Hopkins says : But a short time ago Sir William Crookes predicted that within thirty or forty years England would experience a wheat famine, due to the exhaustion of nitrogen in the soil, that would be appalling in its effect; and Prof, Bela Korasey's warnings to 228 ALFALFA FARMING IN AMERICA. Hungary have been even more emphatic. Indeed, Liebig, more than fifty years ago, in speaking of one of the most common methods of destroying sources of available nitrogen, said: "Nothing will more certainly consummate the ruin of Eng- land than the scarcity of fertilizers. It means the scarcity of food. It is impossible that such a sinful violation of the divine laws of nature should forever remain unpunished, and the time will probably come for England, sooner than for any other coun- try, when, with all her wealth in gold, iron, and coal, she will be unable to buy one-thousandth part of the food which she has during hundreds of years thrown recklessly away." To produce goad crops of alfalfc without the nitrogen gather- ing bacteria requires exceedingly rich soil and liberal applica- tions of barnyard manure or other nitrogenous fertilizer. Even the rich black prairie soil of Illinois does not furnish sufficient available nitrogen for maximum crops of alfalfa. No other crop grown in Illinois requires such large quantities of nitrogen as alfalfa. Applications of available nitrogen to Illinois soil produce crops of alfalfa which yield from two to four times as much hay as crops which obtain all of their nitrogen from the natural supply of the soil. The inoculation of Illinois soil with the proper alfalfa bacteria enables the alfalfa to feed upon the in- exhaustible supply of free nitrogen in the air and the inoculated soil produces just as large crops of alfalfa as soil which has been heavily fertilized with commercial nitrogen. Nitrogen costs about 15 cents a pound in commercial fertilizers, and about 50 pounds of nitrogen are required to produce one ton of alfalfa hay and the weight of the free nitrogen in the atmosphere is equal to about 12 pounds to each square inch of surface of the earth. In Summary. — Nitrogen is constantly being drained out of the soil by growing crops. Wheat, maize, oats, hay, nearly all farm crops take out nitro- gen. It is gathered together in the grains; a grain elevator represents the fertility of many a field. It goes to the cities ; it becomes the food of man. Ow- ing to our wasteful practice, hard to reform in mod- ern civilization, the nitrogen waste is poured into tiie sea. Soon would the soils of the world become INOCULATION AND NITROGEN. 229 barren and mankind starve and perish if the Cre- ative force of the world had not provided this means of renewing the nitrogen of the soiL The tiny bac- teria do it. All clovers gather nitrogen from the air. Alfalfa gathers more than any other known clover unless perhaps the sweet clover be an exception. Al- falfa powerfully enriches the soihon which it grows. Bacteria make it" possible to grow alfalfa. It will not grow long without the bacteria. Hoiv to Get Bacteria. — How are we to get them, how make them most healthful and vigorous? Many schemes have been tried for getting the bacteria in the soil. They can be reared artificially in cultures, and the seed treated with the culture, when each seed ought to be coated with a film of these bacteria. Each seed sown ought to produce a plant abundantly inoculated. These are the so-called commercial cul- tures. The theory is good. Unluckily some influence that we do not understand, maybe the action of di- rect light, usually destroys the vitality of the germs and the cultures do not work. There is hardly any evidence that these cultures are successful. It is too bad that it should be true: the theory is so plausible, the results, could they be secured, would be so delightful. I believe the thing could yet be brought to work, only that with the advance of good farming it will not be long till the demand for such cultures will cease, at least as far as alfalfa is concerned. Curiously enough these bacteria are very pervasive. Once a man begins to grow alfalfa on his farm and to use manure from alfalfa hay. 230 ALFALFA FARMING IN AMERICA. very soon lie has the land all inoculated so that he can not sow a field anywhere that the bacteria do not find the young plants. And when once alfalfa has grown on a field the inoculation persists for several years after it is plowed up. We do not understand these things yet. Maybe we never will. It is mysterious that even the use of manure not made from alfalfa hay, on a farm where alfalfa has never grown, should often result in inoculating the soil with alfalfa bacteria. There is no doubt of this fact. I have seen it repeatedly. Inoculation with Soil. — Soil from a field where al- falfa has grown, or sweet clover (melilotus) has grown, or burr clover has grown, distributed over the new alfalfa field, is a safe and sure inoculation. Some suggest the danger of infecting the new field with weeds or with diseases by this practice. That danger is remote. One hundred pounds of soil will inoculate an acre quite well if it has good distribu- tion. That much soil is taken from a small place of only a few square feet. It would contain few seeds. A few sweet clover seeds in the soil do no harm to the alfalfa anyway. No other weeds are likely to be found where good clover or alfalfa is growing. Method of Using Soil. — How to best manage this soil inoculation? Take the soil from the surface down as deep as the land is well filled with roots. Dig it and carry it home and put it on the barn floor. Spread it, not too thin, and work it over from time to time to help it dry and make it fine INOCULATION AND NITROGEN. 231 for sowing. Do not let the snn strike it even for a moment; sunlight destroys these bacteria. When you have it fine enough for sowing you can either mix it with the seed and sow both together, say 100 pounds of soil and 15 or 20 pounds of seed, sowing them on an acre, or you can sow the seed and soil separately. If you have only a small field or plot to sow, do it late in the day after the sun has ceased to shine, and then harrow it at once. If you must spread it w'hile the sun is shining let the harrow follow immediately behind the soil sower. One can put the soil in a fertilizer drill and drill it into the land. Tli^t is an excellent way. Anyway will do so that the inoculating soil is not exposed to sunlight, but is covered up in the ground. Coating Seed ivith Earth. — The Illinois experi- ment station has developed a very successful way of inoculating alfalfa seed, requiring comparatively little soil for its complete success. Water is heated and enough glue dissolved in it to make the water a trifle sticky. It is then cooled and the seed is well wetted with this water. Earth taken from a good al- falfa field or sweet clover patch is made fine and run through a sieve to take out lumps, roots and stones. It is better if the earth is dry, but it ought to be dried in a dark place, at least not exposed to sunlight. The earth and seed are mixed together till each seed is coated with a film of this dry and inoculated earth. No surplus earth need be used, so each seed is coated. The seed is immediately sown and covered as fast as sown in some manner. Perfect inoculation seems to 232 ALFALFA FARMING IN AMERICA. result. Some farmers who have adopted this plan maintain that it is not even necessary to add glue to the water, though that would doubtless make it some- what more effective. Conditions Favorable to Bacteria. — Now to make those bacteria most healthful, most active, consider their tastes. Acids in the soil promptly kill them off. Much lime in the soil makes them very vig- orous and active. So make the soil sweet with lime, alkaline with lime, not sour. And they feed on air. So let the water out of the land and the air into it. Drain and subsoil or plow deep. Then the soil is ready to work miracles for you. Then one sees com- ing from the land rich crops of alfalfa, many times as much nitrogen as was originally in the soil, feed- ing his animals, feeding the soil if the manure is put back. Inoculation in Advance. — If one plans to sow al- falfa in a year or two he should begin by getting a source of inoculating soil on his own farm. Let him prepare a narrow strip of land across a field, lime it, drain it, enrich it, inoculate it and sow it to alfalfa. Do not say, ^'I will experiment here with alfalfa,'' Alfalfa is no experiment any longer. It is sure to grow on sweet dry rich soil with in- oculation. There is no chance of failure. But on this strip you will get indication of the readiness of your field for alfalfa. If it grows there vigorously all along, and stands the winter quite well, you know that your soil is dry enough, sweet enoug'h and rich enough for alfalfa. And from this land you INOCULATION AND NITROGEN. 23S will get inoculating earth for all the rest of the farm. It may perhaps be necessary to ship in enoug'h for the first strip, though it is today a rare neighborhood that does not have in it either some sort of an alfalfa field with inoculated plants or a sweet clover patch. Once you have the strip of in- oculation on your farm you are independent; you can go on and enlarge as fast as you please. An acre of inoculated alfalfa would give soil enough for inoculating at least an entire county. Searching for Inoculation. — It is astonishing how few farmers have ever seen a nodule on a clover root. They are easily found, especially on some sorts of clovers. One can pull up almost any thrifty red clover root and find nodules in place, looking like little white seeds. On the red clover they are found on the larger roots, as well as on the finer root hairs. The little creeping White clover has nodules in plenty and they are easily found. Alfalfa has nodules only on the smaller finer root hairs. Thus they are not to be seen when one pulls vio- lently a plant from the soil, especially if the earth is hard and clayey. The little nodules remain in the earth. They are very easily dislodged from their hold on the roots. One must take the roots out with some care and perhaps will need to wash the earth away to find the nodules the first time. After he has seen them once and knows what to look for he will find them more easily the next time. Appearance Reveals Inoculation, — After one knows alfalfa well he can tell at a glance whether 234 ALFALFA FARMING IN AMERICA. a field or plant is inoculated. If it is of a rich green color, if it is growing fast, if it looks healthy and happy, be pretty sure that it is inoculated, whether you did it or Nature did it. If, on the other hand, it looks pale and yellow and unhappy and is crowded by weeds and altogether miserable, be sure that it is not inoculated. Inoculated Soil a Fertilizer Laboratory. — Consider what is doing in an inoculated soil where conditions are right and alfalfa is growing thereon. Take the yearly growth at only 4 tons per acre. Four tons of alfalfa hay contain about 176 pounds of nitro- gen, 40 pounds of phosphorus and 128 pounds of potash. Nitrogen is sold for about 15 cents per pound in various forms, often for a much higher price. Phosphorus is sold at a low price for 5 cents per pound. Potash is worth about the same price. Thus in the crop of 4 tons of hay we find nitrogen largely gathered by the bacteria worth $26.40, potash worth $6.40, phosphoric acid worth $2 — all these from one acre yielding only 4 tons of alfalfa hay. The total is $34.80. The manurial value of this yield is vastly more than this amount, since the humus contained is worth more to the soil than one can well estimate. And the value to the soil is nearly double this estimate since we take no account of the root growth, also stored with nitrogen. Prof. Voor- hees estimates the fertilizing value of an acre of al- falfa well grown to be about $65, in comparison of course with commercial fertilizers bought. Soil Building with Alfalfa.— One must not rashly INOCtTLATlON AND NITROGEN. 235 conclude, however, that alfalfa used in any way is a soil builder. There is reason to suspect that al- falfa is one of the most energetic searchers after potash and phosphoric acid known to the soil. The roots go deeper, penetrate more, dissolve more than those of most plants. Thus if the alfalfa is all sold off from the farm it may become steadily poorer and poorer. It is certain that it would be poorer in mineral elements. There have been instances under the writer's ob- servation where the land 'has grown alfalfa continu- ously for some years and nothing returned, where after a time it would not grow alfalfa any longer, nor anything else very well. Exhaustion of avail- able phosphorus would seem to be the most rea- sonable explanation of this phenomenon. In some instances where alfalfa has grown well for some years and then failed it has been impossible to re- establish it
