Millet. ( Panicum Miliaceum. ) The branch of the grass family to which this belongs, is not re- markable for useful members. There are eight hundred and fifty species of this genus, and millet is the only one that is of much val- ue. Millet is sometimes gi-ound for meal, and is said to contain more nutritious matter than anj^ other grain. The name was given to this grain from the latin, mille, thousand, on account of the vast number of its seeds. Speaking of the number of seeds, I am reminded of the interesting table furnished by Mr. Flint: June Grass, about 3,888,000 seeds to the pound. Orchard " " 640,000 " " " Timothy " 1,100,000 " " " Sweet Vernal " 923,200 " " " Indian Rice, Water Oats. (Zizania Aquatica.) Most persons must have observed this beautiful plant growing in the marshes and on the banks of our rivers. The Indians, in their savage state, have always used it extensively for food. Pushing their canoes through the graceful branches, as they grow up out of the water, they bend them, and beat off the seeds into their boats. The stalk itself, when tender, is said to be the sweetest of grasses. The rail bird and the Baltimore oriole are exceedingly fond of its seeds, and seek it on the shores of the Delaware and Chesapeake, to the great delight of the watching sportsman. More than one author has recommended that civilized man should adopt and domesticate this wild, but promising denizen of the forest, one remarking: "This plant seems to be designed by nature to become the bread-corn of the North." Nature sometimes seems to pour her richest gifts into the laps of her idlest children. The amount of ground, which, in wheat, would support one man, in bananas would sustain twenty-five. No "sower goes forth to sow" the wild rice of the cold northwest, but a little observation will reveal the truth, that she brings her choicest treasures to the noble toilers in her fields. Sugar Cane. ( Saccharum Officinarum. ) The sources of sugar are numerous. In early times it was pro- duced from dates, bananas, and other fruits. The maple, in our own section, yields a large quantit3^ Beets, sorghum, corn and sugar cane have it in consideral)le amount, but our greatest source of sup- 70. ply is tlie last mentioned. The West Indies and Guli States yield iunnense ciuantities, which are shii)pod to all quarters of the globe. The mode of planting is quite similar to that practiced in the raising of corn, though cuttings are planted instead of seeds. A very interesting member of the genera §orghum, to which the sugar cane belongs, is broom-corn. We owe this valuable grain to the investigating habits of Dr. Franklin. Being shown a curious brush which had been brouglit from eastern Asia, he examined it carefully, and found a single seed; he planted it, and this was the beginning of the great industries which are now connected with the cultivation of this plant and the pro: — Leersia oryzoides, (Rice Cut- grass.) The first name, printed in larger type, is the name of a genus; the second word, which is afterwards joined to it, is the name of a species of that genus; for example, Lekrsia, (genus), Leersia ory- zoides (the name of a species), and so on through all the expla- nations. 2fi.
