ADDRESS OF JAMES B, EADS, DELIVERED BEFORE THE SAN FRANCISCO CHAMBER OF COMMERCE j^.Tra--crsa? ii, j^. X3. leeo. ST. LOUIS, MO. : Lb VIS ON & Blytbe Stationkhy Company Print . 1880. ADDRESS. Mb. President and Gentlemen : I thank you for the opportunity which you have given me to address you. The question of the construction of a highway for commerce across the American Isthmus, is one worthy of the attention of the people of the whole country, but to those of California it possesses a singu- lar interest and impqjftance. Any prqj ect which promises cheap and quick transportation for the products of your fertile soU, which holds out the hope of setting you free from the depressing effects of the high rates which you are compelled to pay upon all of your exports, may well claim yoar most serious consideration. It is needless for me to dwell, however, upon the importance of this matter, for I know that I am addressing those who fully appre- ciate it. You have learned it from that best of teachers — experience. Year after year you have seen your broad acres yield the most abundant harvests. Blessed with a singularly genial climate and fruitful soil; a popu- lation active and energetic; a ready market for your grain in the East, and a clamorous demand for it from .the markets of Europe, it might well be supposed that your people were rapidly acquiring that wealth which is the legitimate fruit of their labors. Such, however, is far from being the case. Instead of being blest with the prosperity which you should enjoy, there is on every hand evidence of depression. Of what value to you are your enormoTis crops if the cost of transportation prac- tically closes to them the markets of the world? Open up cheap water transportation, and all trouble is at an end. Then, and not until then, will you enjoy that pros- perity which legitimately belongs to the development of your wonderful resources. I am indebted to Capt. Merry for the following figures, as to the accuracy of which I have no doubt: It appears that last year the surplus of your wheat alone amounted to 600,000 ,'tons, and it ife estimated that this year the surplus will reach 800,000 tons. The' average rate of freight around the Horn is $15 per ton, and, after careful investigation, it was found that such cargo could be transported by the Mcaraguan Canal at an aggregate cost of $10 per ton, thus saving upon the total annual shipment the large sum of nearly $4,000,000, or fifteen cents per bushel. This fact is something for the pro- ducers of California to ponder over. I am told by some of your intelligent citizens, who have doubtless thought but little upon the subject, that they have grave doubts as to the value of a ship transit across the Isthmus, because it would probably lose to San Francisco the trade of the Orient. But must this trade, which no doubt benefits this city to some extent, be enjoyed at the. expense of the producers of the State ? Must the farmers lose fifteen cents per bushel on their wheat, year after year, for the benefit that the arrival of an occasional ship . load of tea gives to a few individuals in San Francisco. Must the wine 'growers of the State have their profits continually discounted by the extra cost of carriage around Cape Horn, to retain a trade that must soon be shared by other ports on the Pacific that afe the termini of other transcontinental roads ? "Will not the real inter- ests of this city be more surely advanced by fostering the home industries of the great State of California? Fifteen cents per bushel saved to the farmer in transport- ing his wheat to a foreign market means fifteen cents added to his profit on each bushel of it shipped abroad. It means more than this. It means fifteen cents on every bushel of it that is consumed at home, also, because that which is used in the State has its value fixed by that which is sold abroad. The same thing is true of the profits of the wine and wool growers, the miner, and indeed every producer in the State who has to depend on a foreign market to purchase his surplus. In the four million dollars of annual saving to the State, to which I have alluded, reference is only made to your exports of wheat. If to this be added the increased value of that which is consumed in the State, and the savings on your other exports, the sum will be found great enough to pay for the cost of a ship railway in four years out of the benefits that will accrue to the people of this State alone. If we are answered that to raise' the value of the wheat consumed in the State wUl make it cost more to the home consumers, I reply that the wine grower, the miner and other producers will enjoy like advantages with the farmer, because the ship transit across the Isthmus brings their productions ten thousand miles nearer to New York and seven thousand miles nearer to London, and this fact alone will add increased value to every acre in this State, and benefit every one who breathes the genial air of the Pacific Ocean. In arriving at the estimate of $4,000,000, the tolls to be charged for passing through the canal were fixed at $2 per ton. Now, as the sMp railway which I propose to construct will not cost more than half as much as the proposed canal, the tolls can be reduced in like propor- tion, and thus admit of an additional saving per annum to you on your wheat shipments of $800,000. If the rail- way were built at Tehauntepec, not only would you save in tolls, but there would be a saving in carrying distance over Nicaragua of seven or eight hundred mUes, and a corresponding reduction in the freights. The surplus of which I have spoken is in wheat alone. I do not esti- mate the enormous crop of wool, wine, base ores, tallow, quicksilver and other products which annually leave your shores for distant markets. The construction of the Mcaraguan Canal would require eight years ; that of the railway would not exceed four years. Thus we find that the additional time consumed by the former in in its construction would entail a loss upon you of the aggregate sum of about $20,000,000. Several plans are proposed by which to secure a pas- sage through or across the Isthmus for ocean vessels. M. De Lesseps urges a tide-level canal ; Col. Menocal and his associates a canal with locks, while I am con- vinced that the only practicable solution of the problem lies in the construction of a ship railway. I am not insensible to the fact that the proposal to carry vessels with their cargoes upon a railway seems to many persons rather to be the wild dream of an en- thusiast than the sober, well-digested project of a prac- tical engineer. When I approach the subject, therefore, I realize that there are many prejudices against it, prejudices which it is quite natural for any one, not an engineer, to entertain. I will, therefore, endeavor to explain, in as simple a way as possible, the plans wMch I propose, and I am convinced that when you fully un- derstand them you will be satisfied that a ship railway is entirely practicable. When it was proposed, years ago, to apply steam to ocean vessels, the proposition met with any amount of ridicule, and he who made it was regarded as having lost his reason. Now the white saUs have almost disappeared from the ocean, while the waters of every sea are plowed by the mighty steamers which have become the most reliable vehicles of commerce throughout the world. You will remember that when the proposal referred to was made the propelling power of steam was a well-known fact, and its usefulness for certain purposes was admitted. The objection was that it could not be applied to ocean vessels, and there was no end to the reasons given in support of this objection. The most earnest opponents of this innovation upon established usage were found among ship-owners, cap- tains and sailors, who were all convinced that the applica- tion of steam to vessels would be the inauguration of an era of shipwreck and disaster greater than the world had ever before seen. That era has not yet come, though I am not sure but that there are some who expect and wait for it yet. The idea of transporting vessels upon a railway is by no means a novel one. Forty years ago this method was employed, in transporting canal boats across the Alle- ghany Mountains in Pennsylvania. When it was found necessary to connect the eastern and western portions of the canal at Johnstown and Hollidaysburg, two methods presented themselves — one was to cut through the moun- tains and make the canal a continuous one ; the other 8 was to build a railway to cany the canal-boats over the mountains from one portion of the canal to the other. Inasmuch as the railway was found to be incomparably cheaper, it was constructed and used until the Pennsyl- vania Eailroad made it unnecessary. The railway thus used in connection with the canal was constructed in a very rude and primitive manner. It consisted of longi- tudinal pieces of wood, on which were placed rails of flat bar-iron. This rude structure was found to be amply sufficient to admit of the safe passage of the boats. Now just here I might ask, in passing, whether it does not seem reasonable if, forty years ago, these canal-boats could be thus safely carried over the Alleghany Moun- tains, that a railway can now be constructed which would with equal or greater certainty carry the largest vessels ? He who is familiar with the wondrous improvements in everything connected with engineering in the last forty years would scarcely answer this question in the nega- tive. There is in operation at present, within a few miles of Washington, a railway upon which canal-boats, heavily la^den with their cargoes, are daily transported up a steep grade from the Potomac river to the canal above. In Europe I know of two railways of a similar character now in operation. Surely if a railway can be constructed of sufficient strength to carry a canal-boat, there is no reason why one ' could not be constructed strong enough to carry an ocean vessel. The whole question is one of force, and whenever an engineer can bring a problem down to this, its solution is an easy one. In the construction of a ship railway, of course, the whole work would have to be upon a very large scale. 9 The road-lied must he a solid one, and all machinery employed of a character consistent with the great weight of the vessels to he transported. I propose to employ, instead of two rails, as in ordinary railways, not less than twelve rails, and under each car to place a multi- tude of wheels. In this way the pressure upon the rails would be so distributed that at no point would it equal . that imposed by a>n ordinary first-class freight engine while at rest. One of the first objections presented to the niind by this plan is the great weight to be borne by the road- bed. A cradle for a ship and cargo weighing six thou- sand tons would be about 350 feet long, and would rest on 12 rails spaced 4 feet apart ; hence we would have a bearing 44 feet wide by 350 long, which is 15,400 square feet. This is equal to 780 pounds only on each square foot of the road-bed. A brick wall 8 feet high will give the same pressure. Surely, when we look at the stately houses built on the mud flats which you have reclaimed from your magnificent Bay, you cannot doubt the ability of the solid earth on which the ship railway would be built to sustain the largest ships in transit. If you will observe the slight tracks made by the shoes of a good- sized trotter on one of your dirt roads, and compute the pressure of the horse upon .the earth, you will find it is nearly or quite eight times as great per square foot as our ship railway would impose. The weight of the horse is alternately borne upon two feet only while trotting. If we assume the area of each shoe to be 12 inches, the weight of the animal must rest at each step upon but 24 square inches of earth, or the sixth part of one square foot. . If we assume the weight of the horse 10 to be 1,000 pounds, he would press the earth at each step with nearly eight times as much force per square foot as the largest ship on our railway ; and yet his great pressure leaves scarcely an imprint of the shoe, although to the weight of the horse there is to be added the force or sudden blow with which the animal strikes the earth. On each of the twelve rails, under a cradle 350 feet long, we would have 115 wheels. Each rail would then carry one-twelfth of the six thousand tons, or 500 tons. This would be about 4 tons and one-third on each wheel. As the drivers of a large freight engine at rest give a pressure of over six tons each upon the rail, it will be seen that we really need no heavier rails and tjes than are used on first-class railways. With the pressure of the ship thus distributed, it is plain that she cannot bend, twist or strain in any way, unless the earth gives way under her, and this is not likely to occur if ordinary care be used in building and maintaining the road-bed. It may be said that the rails cannot all be kept perfectly level. This is true to a certain extent, but an inequality of one inch in them could only occur as a result of neg- lig^ice ; but, to remedy any possible unevenness in the rails, each wheel would have over it a strong spiral steel spring that would admit of several inches of play. To avoid bending the ship in changing from one grade to another, the cradle would be run on to what may be caUed a tipping table placed in the line of the railway. This would rest on a fulcrum at the middle and on hy- draulic rams at each end, so that the ends could be raised or lowered to conform to the different grades. To avoid curves in the railway, turntables long enough to receive the cradle would be placed at necessary points in the 11 main track, and on these the cradle would be turned to the right or left, to change the direction of the ship. People who think it impracticable to carry a loaded ship in this way with perfect safety, know but little of the immense resource which the science of mechanics gives to an engineer. There are many ways by which a vessel may be supported, with absolute safety to ship and cargo, when out of the water. It has been suggested that the ship should be carried in a tank of water ; but if the ship is not strong enough to be carried with her cargo on a dock out of water, on a smooth railway, when she has been built to buffet the hurricanes of the ocean, do we lessen the difficulty by building a second vessel, in which to float the first one, which must not only be strong enough to carry the ship and her load, but a mobile cargo of water weighing half as much more ? To carry the ship in a tank of water would convert an im- aginary difficulty into a real one, and besides adding to the cost of the railway, would impose upon it a vast amount of unprofitable cargo. In the case of the ordinary freight cars upon our rail- ways, you have observed that the trucks are placed at each end of the car, and thus that part of the rails where the wheels are placed alone bears the whole weight of the load, while that portion of them between the trucks is doing no service at all. This method of constructing cars is necessary where there are curves upon the road, but as the road which I propose to construct across the Isthmus will be free from curves, the wheels may be placed at very short distances apart under the whole body of the car, and thus the great weight be distributed. With a sufficient number of tracks and wheels, there will 12 be such a distribution of the weight that the largest ves- sels afloat can be carried without imposing any greater burthen upon the rail at any given point than that im- posed a hundred times a day upon the rails of every first-class road in the country. Each wheel will be separate from the others, so that, in case of breakage, any wheel can be taken out without aflfecting the others. The strength of one or two wheels, or that of a dozen of them, is so insignificant when com- pared* with the whole number, that derailment of the car would be almost impossible. The cradle upon which the vessel will rest may be compared with a dry-dock. The only real difference between it and an ordinary dry-dock is that the former is stationary, while this one is placed upon wheels. This cradle or dock upon wheels will be backed down upon the railway, on a grade of about one foot in 100, until it reaches a sufficient depth of water to enable the vessel to be floated upon it. When the ship is in position, she will be safely secured over the cradle, and then the car will be slowly drawn forward. As the water becomes more shallow, the vessel will naturally take her position upon the cradle ; the supports wUl then be moved up against her hull, while still afloat, so that she cannot move on the cradle, and she will then be drawn up the incline until she reaches the level track above. Here two powerful engines will be attached, and the vessel wiU be at once started upon her journey across the Isthmus. At the end of her journey she will be put into the water in the same manner that she was taken out. I think that I have said enough to satisfy you that this plan is a very simple one, and entirely practicable. I 13 have shown you that the question is one in which every element can be accurately calculated. That the distri- bution of weight affords an ample guarantee that the road-bed will be strong enough to bear the burthens im- posed upon it, and surely no one will doubt that if an ordinary dock can be built strong enough to support a large vessel, a dry-dock of equal or greater strength can be constructed which may be moved with facility on wheels. There is scarcely any limit to the power which may be employed. But at this point I will pause for a moment to notice a difficulty which no doubt presents itself to the minds of many of those who hear me. Probably you will all at once concede that the construction of the railroad is. practicable, and that vessels, however great their ton- nage, can be carried upon it ; but you doubt whether it would be possible to carry a vessel upon the railway without straining or otherwise injuring her. I have found that this objection is urged with great pertinacity by many of those who are most interested in seeing the isthmian barrier removed, and therefore, while I know that the fear is groundless, I am prepared to re- spect the opinions of those by whom it is entertained, and concede to them the very best of motives. I call your attention to the fact that the objection referred to is urged, not by educated engineers, but mainly, if not entirely, by non-experts. Now this is not the way in which you reason, my doubting friends, in the ordinary matters of every-day life. K you have a business complication requiring professional advice, you seek a lawyer in whom you have confidence,' and follow his counsel. If you find it necessary to employ the ser- 14 vices of a physician, you accept what he says as verity, and, never doubting, obey his instructions ; and yet, when the most cultivated men in their profession de- clare in the most dmphatic terms that a ship can be safely carried by rail, you are unwilling to accept their decision. Some of the ablest engineers in this country and abroad have declared unhesitatingly that loaded vessels may be thus carried in perfect safety. Among those who have so declared is Hon. E. J. Reed, late Chief Constructor of the British Navy, an engineer of the highest reputation, whose knowledge and expe- rience in ship-building are second, perhaps, to that of no man living. Indeed, I may safely assure you that since I first broached the subject of a ship railway, I have not found a single engineer who has expressed a doubt as to the practicability of the project. Does it not seem reasonable, then, that you should accept the views of those who are best able to decide' these questions, and who would be unwilling to hazard their reputation upon a decision where the least tangible doubt existed as to the correctness of their views ? Those who are most persistent in the belief that a vessel in transitu upon the railway would be strained or burst asunder by the weight of her cargo pressing against her sides, are controlled, not by reason, but (unconsciously no doubt) by prejudice. They imagine that when in its element a vessel has the pressure of the water "constantly outside, to counteract that of her cargo within. In this they are mistaken. In stormy weather and in a rough sea there are times when every part of the vessel is exposed to a strain far greater than it is possible to subject her to on a ship railway. There are 15 times, too, when the resistance of the water is almost wholly withdrawn from different parts of the ship. In crossing on the "Scotia," in heavy weather, I saw one wheel frequently out of the water high enough to drive a horse and cart under it. Of course, a great deal of support was taken away then from the ship's center. At another instant the huge wheel would be almost wholly submerged, and the bow and stern be high in the air. Then, as the ship passed over the crest of that wave, the stern would rise higher still, while the bow would plunge downwards through the trough and rush so deeply into the next wave that no one could stand on the deck at that end of the ship. At the next instant the bow would be uplifted high on the second wave, while the stern would sink almost out of sight down in the trough of the sea. It is not pos- sible to strain a vessel thus severely on a ship railway. If she be bent at all in the direction in which she is most easily bent, longitudinally, she has got to bend the earth itself under her. A vessel that could not ride with safety upon the pro- posed railway is unseaworthy, and wholly unfit to be trusted with either life or property. But it must be remembered that, should it be necessary to give any additional strength to the sides of the vessel, almost any number of supports may be employed. These can be made to extend from the sides or galleries of the cradle, and Govld be so applied that injury to the vessel would be simply impossible. In this connection I may add that it is by no means an uncommon thing to place a vessel, loaded with her cargo, upon a dry-dock for repairs. Quite recently, the " Goethe," one of the large 16 steamers belonging to one of the German lines, was placed with, her fuU cargo upon the New York dry- dock, where she remained for a number of days. In England, the same thing has been done with other large steamers. If no injury results to vessels thus handled, it would seem that their safety upon the movable cradle or dock of a ship railway should not be doubted. But suppose a canal be constructed, is there no dan- ger of injury to vessels passing through it ? I do not know of a single route across the Isthmus where it would not be necessary in the construction of a canal to cut rock to a greater or less extent. In passing through these cuts there would always be danger to the vessel. Were she to take a sheer at such a place, and were she to be carelessly handled, she could not fail to be injured. But, say some, danger from contact with the rock sides can be averted by the use of floating fenders of wood, placed at the sides of the canal. True, but all these appliances involve large expense in their purchase and repair, and increase the estimated cost of the canal and its maintenance. Another and perhaps the leading objection to the canal is its locks. Commerce demands a removal of all barriers, natural or artificial, so far as practicable. Here would be the removal of a natural and the substi- tution of an artificial barrier. A canal with its numer- ous locks would be a constant menace to your com- merce. An injury to any one lock renders the whole work useless until it is repaired. Experience has shown that a navigation dependent upon locks, whether in slack water or canal, is hampered by many delays, while the expense involved in the necessary repairs of 17 the work is a constant tax upon the commerce passing through it. Another strong objection to the ranal is, that when constructed it cannot be enlarged to meet the wants of increasing commerce, without an expense so great as to practically preclude any effort in that direc- tion. This is a very important consideration. A canal so constructed as to meet the wants of present com- merce might be wholly inadequate to accommodate the ships of ten years hence. The tendency of the day is to increase the size and tonnage of vessels, and who can teU what the ships of the future may be? There are a number of canals, constructed years ago, and thought at the time to be of ample proportions, which are now almost abandoned or nearly useless. But it is said: " Construct the canal in such a manner as to leave an abundant margin for the increased size of vessels." This, of course, could be done, but the increase in size means an increase in cost, largely in excess of the amount estimated. Just in proportion as you increase the cost of the work, just in such proportion do jou increase the tolls and charges which will be imposed upon your commerce. These tolls and charges must, of necessity, have relation to and be regulated by the aggregate amount invested in the construction. You must never lose sight of the fact that the great object which you are seeking is to secure cheap transportation for your products. Here is just the weak point in M. Be Lesseps' scheme. That a tide-level canal could be constructed at Panama no engineer seriously doubts, but it is very certain that such a work would cost from three to four hundred million dollars, and that the cost of maintaining it would be beyond all reasonable esti- mate. "Were you to adopt this as a means of escape 18 from tie evils whicli you now endure, you would soon realize that you were in the position of the doves which, through fear of the kite, sought the protection of the hawk. This question of the cost and maintenance of any work constructed upon the Isthmus is a vital one, and should go very far toward influencing you in the conclusions which you reach. In the very able report upon the Nicaraguan Canal, recently made to your Chamber of Commerce, it is esti- mated that eight per cent, per annum could be realized by the company, and the tolls not exceed two dollars per ton. This estimate is based upon one hundred million dollars as the aggregate cost of the work, which sum is less than one-third of that required to build the tide-level canal proposed by M. De Lesseps. The annual tonnage to be carried is placed in this report at one million tons below that estimated by De Lesseps (namely, at only 5,000,000 tons). Now, if the Mcaraguan Canal Com- pany can pay an eight per cent, dividend annually by •the imposition of a toll of but two dollars per ton, the same dividend can be declared by the ship railway upon the imposition of a toll of but one dollar per ton, for the reason that the cost of the ship railway will not exceed fifty millions of dollars, or one-half the sum required for the construction of the canal ; nor will its maintenance and operating expenses be in any greater proportion. I am convinced that the estimate of the cost of con- structing the canal at Nicaragua is far below what it wiU actually cost, and that it cannot possibly be built as pro- posed for less than $100,000,000. Should the proposed work be constructed, it will be found that the cost of improving the harbor at Grraytown will far exceed any figure which the sanguine advocates of the scheme are 19 now willing to place upon it. The cost of maintaining its harbors when improved, that of dredging the canal and keeping it and its locks in repair, and a hundred other minor expenses, demand the attention of those by whose products and labor the necessary interest on the capital invested must be paid. Standing in your presence to-day, and conscious of the full import pf my words, I declare to you^ 1. That a ship railway can be constructed at one-half the cost of a canal with locks, and in one-half the time. 2. That, when completed, the railway can be maintained and operated at a cost not exceeding that of a canal. 3. That your largest vessels, with their cargoes, can be safely carried from ocean to ocean in one-half the time required for a passage through the canal. These considerations alone, it seems to me, should de- cide you at once in favor of the railway. Bixt these are not the only ones. The railroad, when completed, can be enlarged from time to time as the wants of commerce may demand. And should the commerce using the road demand a double instead of a single line of tracks, the work can be speedily done and at a reasonable expense, and without interfering with its traffic. Another matter which I desire to suggest is this : Wherever a canal is practicable, a railway is also practicable ; and at some points a railway could be constructed where a canal would be out of the question. As you reduce the dis- tance for the carrying of your freight you reduce the cost of transportation. There can be no doubt a ship railway could be constructed at Tehuantepec, and if this route were selected almost seven hundred miles of trans- portation would be saved over that necessary if the tran- sit was by Nicaragua. 20 But I have already trespassed too long upon your attention, and will draw my remarks to a close. The opportunity is now afforded you to have a work con- structed which wiU strike the shackles from your com- merce, and contribute wealth and happiness to your people. When I proposed, years ago, to give to New Orleans and the Mississippi Valley a safe and deep out- let to the Gulf, and assured the people th^ I was able soon to remove the barrier which barred the entrance to their mighty river, I was met with the same old cry of "Canal;" "Give us a canal!" said they, "that is the only relief from our troubles ; a canal and happiness are synonymous terms." When I pressed upon Congress and the people my project for improving the mouth of the river by the application of the Jetty System, a reso- lution was actually passed by the New Orleans Chamber of Commerce recommending the construction of a canal from Fort St. Philip to the Gulf, and a letter, earnestly requesting me to cease further eflfbrt in behalf of the Jetties, was addressed to me by a large number of the merchants of that city. Convinced that these peoplfe were misguided ^and blind to their own best interests, I heeded not their requests, but pressed my project with redoubled zeal until success attended my eflforts, and the work was intrusted by Congress to me. To-day the Mississippi River is open to the largest ship that floats, and all of the business interests of New Orleans, cursed as they were with stagnation and decay, have been in- spired with energy and blest with new life. To the pro- ducers, the merchants, the business men of this great State, are now offered like benefits. It remains to be seeji whethet my efforts will be hampered by your oppo- sition or encouraged by your aid and influence. Review of Capt Phelps' Pamptilel, entitled "Transporta- tion of Ships on Railways," by James R Eads. Captain S. L. Phelps' pamphlet is so full of errors that a brief exposure of them is necessary to prevent wrong im- pressions. It contains insincere statements of facts about which he is no doubt fully informed ; and absurd errors in naval architec- ture and civil engineering, which betray a lamentable want of knowledge of some of the simplest physical laws. To give an idea of the number of these errors, I will enumerate them as I proceed, and leave the reader to refer each to its proper origin. 1st. Captain Phelps refers to General Barnard's survey of the Isthmus of Tehuantepec, made twenty years ago, to show that the grades and curves for a ship railway must be excessive, but he is quite silent about other surveys for rail- ways made since, whicli have developed better lines. He says: " If a ship can be hauled up gradients of 115 to 150 feet per mile, then the elevations can be surmounted, pro- vided the ship can first be changed sufiiciently in inclination to the horizontal." Mr. E. A. Fuertes, an eminent civil engineer, now Dean f the Department of Civil Engineering in Cornell Univer- sity, was chief engineer of Commodore Shufeldt's expedi- tion which surveyed the Isthmus only nine years ago. In a recent letter to me he says : " I can assure you, upon knowledge of every inch of the ground, that you will find no difficulty about curves, grades or bridges. The ascent of the Atlantic slope will offer no more difficulties than the Hudson River Railroad, and on the Pacific side, either one of the three passes in the neighborhood of Tarifa or Chivela will allow of no steeper grades than 25 to 35 feet per mile to bring you down to the Pacific plains." 2d. Captain Phelps says : " The displacement of a num- ber of steamships in service, indicate weights of ship and cargo reaching from 9,000 to 12,000 tons, their length being from 450 to 500 feet and upwards. Hence ability to carry a ship and cargo weighing 12,000 tons is necessary." Captain Phelps cannot cite a single merchant steamer in service (the G-reat Eastern excepted) whose displacement is 9,000 tons when loaded, much less 12,000. Lloyds' register will show that 90 per cent, of the world's commerce is carried in vessels, the largest of which will not, when loaded, weigh over 4,000 tons. But three steamers in the world (ex- cept the Great Eastern) are in service that exceed 450 feet. These are the Britannic and Germanic, which only exceed it by five feet, and the City of Berlin which is 488 feet long. One or two are building that are over 500 feet, but they are not in service. 3rd. Captain Phelps declares that tilting tables to change the grades on the road will weigh 24,000 tons each, and says : " This change in inclination would become necessary many times in the distance across the Isthmus." The tilting tables, if necessary, would not weigh more than one-tenth of 24,000 tons. But the surveys already made, and those referred to by Mr. Fuertes, prove that the grades are so easy that such devices as tilting tables will be wholly unnecessary. 4th. Captain Phelps says, under the head of " Change of Direction : " " This would be frequently necessary in that mountain country and can only be effected by use of turn- tables, which must be 500 feet, or more, in diameter, and must carry 24,000 tons and their own weight, which would probably approximate to the weight carried, or say another 24,000 tons and the whole weight would again be 48,000 tons, more or less." Surveys thus far made, show that but three turn-tables to change the directiou of the road, will be necessary. Careful estimates prove that the car to carry the ship will not weigh more than one-quarter as much as the heaviest vessels to be transported or say 1,500 tons. This with 6,000 tons for the ship and 500 for the engines would be but 8,000 tons on the turn-table, instead of 24,000. Pivot drawbridges are now in use on the Mississippi River which are 460 feet long. A turn-table for the ship railway will be no longer, and with its wheels, &c., would not weigh one-tenth as much as Captain Phelps asserts. Hence with a 6,000 ton ship the entire load, turn-table and all, would not be one-quarter of 48,000 tons. 5th. He estimates ^the ship and the ear, cradles and sup- ports to carry the ship, at 24,000 tons. This estimate is three times as great as it should be. 6th. He says : " The model of the ship must be known that cradles and supports can be made in advance to accu- rately fit her form." Without investigating the strength of ships, he has adopted the popular error that their sides are so weak that supports must be put all around them when out of water. If a barrel of beans be afloat, the water will support its sides just as it does a ship, but it does not follow that it must be carefully laid on supports, hollowed out to fit it, when taken out of the water. The supports on which the ship rests in a dock are placed chiefly under her keel, and the remainder under the flatter parts of her bottom. By very simple devices these are made adjustable to suit a vari- ety of vessels of similar tonnage. A number of different sized cars would be provided to suit the different classes of vessels. The same car that would be suitable for large steam- ers would not be used for sailing vessels. 7th. He says : " JS'o two vessels have the same form and cradles must be fitted for each vessel carried." This statement is likewise erroneous. The Germanic and Britannic are alike in form ; so are the Baltic and Oceanic ; 80 too are the Celtic and Adriatic, I could name scores of vessels whose forms are alike, if I had space. 8th. The Captain says : " Builders, owners, seamen, and underwriters all condemn the railway plan as impracticable, if for no other reason than that ships cannot be taken out of water safely with cargo on board." Here are three distinct misstatements : 1st. Builders do not all do any such thing. Messrs. Edward Hartt and F. L. Fernald, of the United States Navy, and E. J. Reed, of the British Navy, are builders whose scientific educa- tion and practical experience in constructing wooden and iron ships of the largest sizes, entitle their opinions to the highest possible degree of respect ; and they have de- clared over their own signatures that the proposed ship rail- way is not only entirely practicable, but, for several reasons, is superior to a canal. 2nd. Seamen do not all condemn it. Commodore Shufeldt, Captain Silas Bent, and Commander Farquhar, seamen whose education in the United States Navy and whose standing and experience entitle them to quite as much respect as Captain Phelps enjoys, do not condemn it, but encourage me to go on with the work. 3rd. It is untrue that ships cannot be taken out of water safely with cargo on board. A letter dated February 14th, from Mr. William F. Buckley, President of the New York Balanced Dock Company, gives the following list of vessels taken out on his dock with cargoes in them : Ship Grreat Victoria, 2,386 tons. " Triumphant, 2,046 tons. " America, 2,054 tons. " Hagerstown, 1,903 tons. " S. C. Blanchard, 1,903 tons. Steamer (Colorado, 2,765 tons. Rio Grande, 2,565 tons. Thingvalla, 2,436 tons. Monarch, 2,366 tons. Lepanto, 2,310 tons. State of Nevada, 2,488 tons. Mr. Buckley in his letter says " "We do not refuse any class of ships or steamers, even with their coals and cargoes on board, whose length does not exceed the length of the dock. In every case in which we have taken up steamers with cargo in, it has been done without the least strain or injury to the vessel. As the rule is to make a charge for raising cargo in the vessel, they usually come to us without cargo." 11th. Starting on the hypothesis that vessels will weigh two or three times as much as they really do, and that the cars must be three times as heavy as need be, the captain says : " Allowing five tons pressure upon each wheel under the ship-car, there would be required 4,800 wheels. These placed at three feet center to center, would require 14,400 feet of rails, or twenty-eight rails of 500 feet in length, or two and one-third times more than Captain Eads adopts ; and the rails, if under the ship, would hardly be twenty inches apart ! " If Captain Phelps had indulged in a greater flight of fancy, and started with ships of fifty thousand tons weight, he could have drawn conclusions still more startling and equally unreliable. 12th. The Captain makes the following remarkable state- ment : " When in motion the ship would practically rest upon four points. When cars have four wheels the weight is equally distributed over them ; add two wheels, and four of the six will still carry the load, but the weight will be trans- ferred momentarily according to deviation in the plane passed over. This source of disaster from overloaded wheels would be a constant danger." This is the sheerest nonsense imaginable. Mr. J. J. Mann superintendent of the Chicago, St. Louis and B'ew Orleans Eailway, informs me that the two-story brick depot in Jackson, Tennessee, was moved 700 feet north, and twenty feet east of its original location. It is 140 feet long and 40 feet wide. It weighed vastly more than the Egyptian obe- lisk recently erected in New York, and was moved without 6 cracking its walls. It had probably 500 rollers under it. Captain Phelps would lead the reader to believe that it must have rested at times upon only four of them. The same building could be moved 7,000 feet or 700,000 feet in the same manner and with equal safety. 13th. The Captain says : "In a distance of 150 to 180 miles there must be several sidings for passing ships and many " turn-tables," beside frequent tilting-tables for changing the inclination of the ships to the horizontal." Evidently Captain Phelps had forgotten that in another part of his pamphlet he says : " The ship railway involves about as much canal as the l^icaragua route." And in another, that, " the Isthmus is 143.5 miles wide." The Cap- tain should have a better memory. 180 miles of railway and 173 miles of canal is rather too long to get across an isthmus only 143.5 miles wide. 33 miles will be river navigation and 12 miles of bay, leaving about 100 miles of railway. 14th. He says : " The weight to be transported is equiva- lent in amount to over 1,200 freight cars, and their load." I have shown that the maximum weight to be transported is only 8,000 tons. Hence it is only equal to 400 freight .cars and their loads. 15th. The captain gives his readers the following sample of his knowledge of railway engineering. "The ship in view is one-tenth of a mile in length. A change in the inclination of the road-bed from the horizontal to grades of ten, twenty, fifty or more feet in a mile would suspend this vessel by the ends while entering upon the new gradient. At one point the ship's middle portion would be, in such changes, from six inches to two and one- half feet, and so on, above the level of the platform car, and would not therefore rest in the cradle at all." Now let us suppose the grade is ten feet in a mile. In the length of the ship which is the tenth of a mile it would be one foot. Let us suppose the worst possible case, that where the change of grade is made abruptly from a level plane ' When the ship has advanced half her length tip the grade, one end will be just six inches higher than the other, and the angle where the grade changes will only be three inches further from the ship than if the change did not occur ; just half as much as Captain Phelps states it. This is the posi- tion where the middle of the ship, if absolutely rigid, would be at the greatest distance from the track. Hence if the ship bo 528 feet or one-tenth of a mile long, and a grade of 50 feet be made to form an angle with a level plane, the middle of the ship can only be one and one-fourth feet further from the angle, and not two and one half feet, as stated. It is easy to see that if the grade line and the level were united by a vertical curve only as long as the ship, with a versed sine or deflection of seven and one-half inches, the middle of the ship would then only be half as far from the track. But there is no reason why this curve should be limited to the length of the ship. The change of grade may be made in one or two, or even three miles, instead of at one point, and the possible bending of the ship will be thus almost wholly prevented. The great box tubes of the Britannia bridge are nearly 500 feet long and are as strong as any ship, yet they bent several inches with their own weight when erected, and are deflected from one to three inches more with every passing train. A ship 528 feet long would bend six inches in her length without injury, but on the ship railway the change of the grade will be so gradual that no percepti- ble bending can occur. 16th. The captain says : " A ship while out of water is the heaviest of structures for its strength." This is wholly erroneous. Very few ships are as heavy as the brick depot that was moved so far in Jackson, Tennes- see. Yet any ship of half its weight is vastly stronger. Hence it is a much lighter structure for its strength. 17th. The captain thus displays his knowledge of physics. He says : " Resting in the water, the ship is sustained by a medium entirely surrounding the bottom and pressing in equal force upon every inch of its surface." This is a mistake. The water presses against the deeper parts with greater force than it does against the parts not so deep. The pressure at any point depends upon the vertical height of the water above that point. 18th. Again: we are told; " "Whether rolling or pitching, the support from the water is uniform, at all times and at all points.'' This is a most astonishing statement, when we remember that it comes from one who was once a captain in the United States navy. In storms the pressure upon any one part of the hull is constantly changing. If the support were "uni- form at all times and at all points," such a thing as a ship being strained in a storm or foundering at sea would be unheard of. 19th. Captain Phelps tells us : " Moreover there is com- paratively little motion in the bottom of the vessel, what- ever there may be 30, 40, or 50 feet above it, because motions at sea are from the bottom as the centre." This will be news to naval architects who have hitherto carefully considered the various weights, and their positions in the ship, to determine the centre of gravity and the metacentre of the vessel, so as to secure the greatest degree of steadiness for her. Captain Phelps has made the novel discovery that the bottom of the ship and not her centre of gravity, is the centre of motion. Captain Coles, E-. ^., the builder of the celebrated and unfortunate British turreted ship "Captain," made the same mistake on this point that Captain Phelps has made, and it cost him his life. The centre of gravity of motion in the " Captain " was so high (that is, so near the metacentre) that when the ship got to rolling, a slight squall was sufficient to overturn her. She carried Captain Coles and almost every soul on board to the bottom. This could not have occurred if " motions at sea are from the bottom as the centre." The centre of motion in this case was prob- ably 30 feet above the bottom. 9 I was in England when the Captain was being built and desiring some information about her, I sought Mr. E. J. Reed, the chief constructor of the navy, and learned from him, with surprise, that he had nothing to do with her, as she was placed by the government wholly under the charge of Captain Coles, because he, Reed, had disapproved of Coles' designs. The sequel proved that a man educated to navi- gate a ship is not always familiar with the scientific princi- ples involved in her construction and servitude ; and still less frequently is he competent to apply them in practice. Ship-building has, in the present century, advanced from the category of mechanic arts. It is now recognized as one of the sciences. Some of the ablest mathematicians and engineers of the present age have devoted years of labor in elucidating the principles involved in its problems. It is true that many ships, probably the majority of them, are built by men wholly unfamiliar with the mathematical processes by which the various members of the vessel are proportioned ; but these have been tabulated in what are known as Lloyd's rules. These rules require that vessels of certain tonnage shall have plates, beams, ribs, kelsons, &c., of certain dimensions in certain parts of the ship, while these dimensions are again modified according to the pro- portionate length, breadth, and depth of the vessel. Unless vessels when completed are built in accordance with these rules, the Underwriters decline to insure them, or charge increased rates for so-doing. Hence, a mechanic familiar with plate-iron work, or boiler making, may establish a ship yard, and if possessed of sufficient knowledge of the art of ship building to transfer the lines of a small model to the floor of his moulding loft, may, by the observance of Lloyd's rules become a successful builder, without knowing much more about the science of ship building than Captain Phelps does. Such builders may upon the solicitation of Captain Phelps, declare the ship railway totally impracticable. But 10 certainly the opinion of such persons should not be put in the scale against men like E. J. Reed, Edward Hartt and F. L. Fernald, constructors who have studied the science of ship building as a profession; who are competent to revise Lloyd's rules; to determine the intensity of any strain to which a vessel may be subjected, in the water, or out of it ; to ascertain its ability to resist such strain ; and who have an extensive practical experience in the mechanical details of their profession. 20th. Captain Phelps says : " The Suez Canal, 100 miles long, costs $800,000 yearly. The Mcaragua Canal proper is 53.17 miles long." The reader would infer from this deceptive statement that the Suez canal is nearly twice as long as the Nicaragua. Much of the Mcaragua route lies through the Lake and much of the Suez route is through the Bitter Lakes. These had to be dredged to deepen them, and much dredging must be done through Ijake ]!«J"icaraugua to deepen it. When storms prevail this part will be very difficult to navigate, as vessels will be liable to be blown out of the cut and stuck in the mud. They frequently ground in the l£«kes at Suez. It requires two days to pass through the Suez canal, al- though it is only 96 miles long. As the Mcaragua route is nearly twice as long, it would probably take three or four days to go through it, if, like the Suez canal, it had no locks ; but as it must have many locks, these will add another day or two of delay. The French engineers, knowing the great danger of accidents to the locks, as well as their delay, wisely determined to have none of them at Panama. 21st. The statement that the Suez Canal cost but $800,000 yearly is another error. I have before me the report of the three British directors, (given to me by one of them) in which it is stated that it cost in 1878, 6,248,663 francs which is equal to $1,249,782, or nearly 57 per cent, more than Captain Phelps would make the reader believe. 22nd, Captain Phelps says: "As projected, the railway 11 scheme involves about as much canal as the Nicaragua route, and will have two locks." Here are two misstatements, and it can scarcely be possible that Captain Phelps was ignorant of the facts in either case. 1st. It is not contemplated to have a canal through more than live or ten miles of swamp to connect the Uspanapa River with the firm lands beyond ; 2nd. There will . be no locks at all in the entire route. The two ends of the rail- way extend, with a grade of but one foot in one hundred, down under water far enough to float the vessel over the car that is to carry it. Hence locks will be unnecessary. 24th. Captain Phelps says : " The distance saved for steamers by way of Tehuantepec between the Atlantic and Pacific ports of our country would be only 510 miles, as com- pared with the distance via the Nicaragua route." This statement is probably made on a system of general average. Having extravagantly overstated so many other matters the Captain evidently wishes to average his errors by extravagantly understating this distance. Hon. C. P. Patterson, Superintendent of the Coast Survey, in- forms me that the difference in favor of the Tehuantepec route from the mouth of the Mississippi to San Francisco, over the Nicaragua route, is 1193 nautical miles ; or 1372 statute miles. And that between New York and San Fran- cisco it is 753 nautical or 860 statute miles. 25th. He says : " The estimated cost of the canal is $41,- 000,000 ; that of the railway, for which no surveys have been made, is $75,000,000. Doubling these estimates to cover all kind of contingencies, will make the canal cost $82,000,000, and the railway $150,000,000." As he is no doubt familiar with his own estimates we must concede to him the right to double them as often as he thinks necessary. But being satisfied with the estimates we have made for the ship railway, and which Captain Phelps has never seen, we object to his increasing them simply be- cause he finds his canal estimates so largely understated. 12 26th. The Captain says : " Ten million gross receipts for the railway, would, after deducting 60 per cent for expenses, leave $4,000,000 net, or 2| per cent, on outlay] The average expenses of railways bear a larger ratio to re- ceipts than 60 per cent., and it cannot be doubted that, if in any degree practicable, the ship railway would be enor- mously expensive in proportion to gross receipts." Here the Captain is again mistaken ; several first-class roads are worked for less than 50 per cent., and they handle their cargoes by hand. In the ship railway it would be handled exclusively by machinery, thus greatly reducing the expense, and as every thing must be of the most sub- stantial character, the ratio of expense of maintenance will be much less than with ordinary roads. .27th. Captain Phelps says further: "The United States are asked to fasten this needless tax on the country, and to do it by putting up a vast sum of money to try an experi- ment for which a favorable result cannot be anticipated." I can only account for this inexcusable misstatement by the fact that Captain Phelps had become so careless in making the twenty-six others which I have already ex- posed, that he determined to " cap the climax" in this one. The United States is not asked to put up a vast sum of money to try an experiment. It is not asked to put up a dollar for any such purpose, and if the ISTicaragua scherue can only win support by such totally unfounded statements as these, its intrinsic merit must be small indeed. The " exper- iment," as Captain Phelps calls it, is to be made by private capital alone. Ten miles of railway with its requisite cars, engines, &c., and the terminal works for taking a ship, weighing with her cargo 2,000 tons, out of the water on to the road, is to be built with private capital. When this is done, if the experiment of transporting this loaded ship without injury at 6 miles per hour over the road is a failure, the United States loses absolutely nothing. Only af- 13 ter this has been successfully done is the Government liable, and then for only 6 per cent, dividends on $5,000,000 stock. The total amount of stock to be guaranteed is but f of the amount of the $75,000,000 required to build the road. Like amounts of stock are only to be guaranteed as other sec- tions are finished and tested. The tests increase in severity from time to time ; the last $10,000,000 guaranteed, depends upon the safe transportation of a ship, weighing with her cargo 4,000 tons, over the entire line at 6 miles per hour. A ship of this size would be taken for the first test, but the harbors must be deepened before so large a ship could enter them. This is as large as any ship which has yet visited New Orleans, although there has been 30 feet depth through the jetties for the last eighteen months. Captain Phelps declares at one moment that this cannot be done, and in the next he betrays his fear that it can be, by striv- ing to prevent me from doing it at my own cost and risk. To defeat a trial of the experiment he does not hesi- tate, as we have seen, to make a statement which totally misrepresents the facts, and actually tells the reader that the United States is asked " to put up a vast sum of money to try an experiment for which a favorable result cannot be an- ticipated." I have not space to follow Captain Phelps through the mis- representations, absurdities, and nonsense with which his pamphlet abounds, but which are nevertheless so stated as to mislead many intelligent persons who do not take the time to examine the subject. The twenty-seven which I have pointed out show that he knows nothing about the principles of the problem he undertakes to argue, and that he is very reckless and unfair in his statements. As it is not to be supposed that his pamphlet could have been published without being first examined and approved by the chief promoter of the Ificaraguan scheme. Admiral Ammen, he must, unless it be disavowed, become equally responsible for its ridiculous blunders and deceptive state- ments. 14 To avoid discussing the real merits of my proposition, other unfair opBonents strive to create the impression that I am ask-, ing a government guarantee to pay for making an experi- ment. The guarantee is not asked to pay for an experiment, successful or unsuccessful. It is asked in consideration of certain valuable benefits which my grant from Mexico enables me to give to the United States, or to any other government which will aid the construction of the Ship Railway. In consideration of the guarantee I agree 1st, to trans- port the war vessels, troops, property and mails of the United States free for 99 years. 2nd. To give to it the right to reduce the tolls on the road. 3rd. The right to discrim- inate in favor of its own commerce and that of Mexico, when fixing the tolls. 4th. To transport no vessels of war belonging to any nation at war with the United States, and 5th. To pay back to the United States every dollar that may be advanced under her guarantee. As the ship railway is opposed on the ground that it is an untried experiment, the actual demonstration of its practica- bility is to be made at the risk of myself and associates, be- fore any liability on the part of the United States can pos- sibly take effect. And as it is charged that my grant from the Government ot Mexico does not authorize rae to give to the United States the above valuable advantages, the guarantee is also not to take effect until after the Mexican Congress shall have signified its assent to the proposed agreement. Captain Phelps shows his unfairness in the premises by republishing in his pamphlet the misstatements of the Few York Times of February 3rd, conveying certain false im- pressions which were fully exposed and corrected by me a few days afterward. The Times lays much stress upon the fact that the grant contains a clause which declares that " The company shall be Mexican even though some or all of its shareholders be foreigners, and shall be subject exclu- sively to the jurisdiction of the tribunals of the Republic 15 in all matters of which the cause of action may take place within its territory." It will be seen that the proposition made by me to the United States does not propose to give to it any right of eminent domain on Mexi- can soil, nor any right to interfere in the control of the road. It will, if accepted, be simply an agreement between the ship railway company and the United States, sanctioned by Mexico. Mexico could not give to the United States the right to discriminate in favor of our commerce on the rail- way without conceding to other nations with whom it has treaties, the same advantages. The usual treaty clause which provides that the nation making the treaty shall en- joy all the rights and privileges of the most favored nations, would give to each nation having such treaty with Mexico the same right in favor of her commerce. By the concess- ion, however, she gives the company the right to charge certain maximum rates of toll, and leaves it optional with it to charge as much less as it pleases. It does not impose upon the company any obligation to make the tolls uniforrn to all nations. The grant requires that the road shall be open to the commerce of all nations at peace with Mexico, and they will have a right to use it at the maximum rates of tolls, or at such lower rates as it may suit the interests of the company to fix. It does not require the company to transport the war vessels of any nation but Mexico. Nor does it forbid the transit of such vessels belonging to other nations except in case of war. The grant was drawn for a difterent purpose from that which was contemplated by either the Panama or the ]!Tica- ragua concessions. They are for the benefit of Europe first and of America afterwards. This is the American route, and the ship railway. is for the benefit of the commerce of IITorth America first and that of the world afterwards. It is the American route because it is 1,500 miles nearer by it from our ports on the Atlantic to those on the Pacific, and 2,200 miles nearer from the mouth of the Mississippi to 16 our Pacific ports than it is by Panama ; and although these distances are somewhat less by Nicaragua, the greater delay in passing through the latter route would destroy all benefit which the saving in distance would otherwise make. Mexico gives most valuable aid to the enterprise and she has a right to expect benefits greater than -those which are to be enjoyed by nations who give no aid to it. If the United States aids it, she will enjoy all the ad- vantages reserved to Mexico, and discriminations will be made b}' the company, in favor of the commerce of the two countries in consideration of the aid which they give to the compapy. Mexico gives authority to the com- pany to secure aid from some other government and it prescribes the manner of doing it. Like any other nation that has achieved its independence, it is jealous of any foreign domination of its territory, and hence it declares that any sale, mortgage, or transfer of the railway, franchise, or lands of the company to any other government, shall work a forfeiture of the grant ; but it de- clares that the company may hypothecate the revenues of the road to any other government that will aid it with money or guarantees, provided the terms of such hypothe- cation do not conflict with the other provisions of the grant, that is to say : provided the company does not give to such government the right to take possession of the road, or the right to operate it ; or to acquire title to its lands. It gives to such government only the right to intervene through the courts of Mexico, in case of any bad faith of the companj'^, and to have receivers appointed by its courts to collect the revenues and disburse them according to the terms of the agreement with the company. Any one who supposes that any independent government would consent that another government should enter upon its territoiy and take charge of a railway within its borders, or come into possession of any important works upon its soil, knows but little of international affairs. 17 The United States would scarcely be able to make such an ar- rangement with any one- of the weak States of Central Amer- ica that requires its protection. It has no right to ask of Mexico that which it would not itself grant to any other independent government. Mexico will protect the United States in the full enjoyment of all the benefits the ship rail- way company offers to give her, and that is all she needs. When she refuses to recognize and consent to the terms I offer to the United States, it will be time enough for Cap- tain Phelps and Admiral Ammen to repeat the Times' mis- statements. Captain Phelps closes his pamphlet with several letters expressing adverse opinions as to the practicability of the Ship Railway. In one of these Mr. John Roach says : " In my opinicm a ship or steamer of large dimensions cannot in safety be taken out of the water with cargo on board, as there would be great danger of injury to the hull, and consequently cannot be safely transported with cargo on a Ship Railway." As Mr. Buckley gives the names of five large ships and six large steamers that were taken out on his dock with their cargoes on board, and without injury, it is evident that Mr. Roach's opinion is based upon incorrect premises, and is therefore without value. Several large vessels have been taken out with their cargoes on board, in the docks and on the ways of Messrs. Cramp and Sons, of Phila- delphia, and others have been taken out on other docks, besides Mr. Buckley's, in ISTew York, but I have not yet had time to ascertain the names and sizes of these vessels. In a printed letter, addressed to Hon. J. Floyd King, over the signature of Admiral Ammen, the above letter of Mr. Roach is preceded by the following : " The ^ew York Herald of March lOth, 1880, states that Captain Eads said before this committee that E. J. Reed, formerly Chief !N"aval Constructor of Grreat Britain, Mr. John Roach an eminent ship builder, and Mr. Henry Steers, had received his plans with favor." 18 I have never stated to any body that Mr. Roach received my plans with favor. I stated to the committee referred to, that in answer to my question as to how much Mr. Roach thought the bow and stern of a ship 450 feet long could be jacked up without danger to the ship and without lifting her off the central blocks, that he had replied : " 6 inches." This is the extent of my statement respecting the opinion of Mr. Roach. After the letter of Mr. Roach, however, is this statement. " Wm. H. Webb, Esq., the celebrated ship builder, concurs in this opinion." Mr. Wm. H. Webb informs me that this statement was published without authority, and that he never expressed such concurrence of opinion. Admiral Ammen in the letter referred to makes the following statement also : " The first proposition I saw published by Captain Eads, referred to the transportation of water-borne vessels. The letter of Mr. Reed, published in the Washington Post to-day, would seem to refer to similar conditions." The impression herein conveyed is, that I was then proposing to transport ships in caissons or tanks of water. I have never proposed any such thing, nor does Mr. Reed's letter convey the impression that he proposed such method. A letter from Messrs. Harlan & HoUingsworth is given by Captain Phelps in which they say : " If the foundation of the railroad, having six tracks, could be made substantial so as not to yield under the immense weight of a loaded ship, we believe that a cradle could be constructed to receive the ship and transport it the distance named without injury." This is certainly not damaging testimony to the ship railway. The Atlantic works of Boston are also quoted. They start with this declaration : " Our positive ignorance of this matter throughout, forbids our expressing any opinion at length." They say : " Were it not that Captain 19 Eads has already done wonderful things we should not hesitate to declare this scheme impossible of execution." This certainly modifies very much, any adverse opinion ad- vanced in the same letter. Under the head of " Opinion of Civil Engineers," there is the statement that " the Hon. John Oonness, formerly of the United States Senate, has forwarded the following expression of opinion of an able engineer : ' Admiral Ammen's testimony, before the select committee, tells the whole story, and puts Eads' absurd project in its right light.' " As the name of this able engineer is not given to the public it is not necessary to quote his opinion further. The only civil engineer whose name is published by Messrs. Ammen and Phelps as doubting the practicability of a ship railway across the Isthmus of Tehuantepec is Mr. W. J. Mc- Alpine who, it is said, has written " That he regarded the Eads scheme quite as visionary as M. de Lesseps canal at the ocean level, and that he would discuss the subject without delay." He is pronounced by Admiral Ammen " one of our most eminent engineers," and by Captain Phelps is further endorsed " as second to no engineer in this country." Mr. McAlpine's opinion would have commanded greater weight if he had not been president of a convention of engineers at St. Louis in 1867, which unanimously declared that the long spans and deep foundations of the bridge I was then building, were totally impracticable. 20 Expert Testimony in Favor of the Ship Railway. To offset the adverse opinions of Messrs. McAlpine and Roach, who are really the only experts of weight referred to by Messrs. Ammen and Phelps, and to show how over- whelming is the expert testimony in favor of the Ship Rail- way, I submit the following letters. The first was pub- lished in the London Timeshj Hon. E. J. Reed, M. P. C. B., formerly Chief Constructor of the British Navy : " To the London Times. " I write to express the hope that the project of substituting a ship railway across the Isthmus of Panama for the costly canal which is in contemplation, referred to in the letter of your Philadelpliia corre- spondent in the Times of this day, wiU receive in this country and in France the consideration which it well deserves. I have for some time past had under consideration a similar scheme of my own for conveying ships across the north of the great peninsula of Florida, and although I have not had leisure to develop it sufficiently to jus- tify me in putting it in detail before the public, I have gone a long way toward satisfying myself that it is a feasible plan and highly economical in comparison with a sliip canal. " Mr. Eads, who has now announced and advocated the plan in America, is an engineer of the greatest ability, distinguished alike by the greatness of his engineering conceptions and by the theoret- ical and practical knowledge which he brings to bear upon their de- velopment. I first made his acquaintance in connection with war vessels and macliinery constructed during the American war, and found him most able in grasping the essentials of the war-ship prob- lem and in the application of steam to the objects in view. He has since given abundant evidence of engineering skill in other spheres and on larger scales. " It may not be generally known that this country has done much in the way of lifting vessels bodily from one level to another, both in the case of the hydraulic docks of Mr. Edwin Clark and in the Ander- ton barge-lift in Cheshire, where the Bridgewater Canal and the Eiver Weaver (of which the former is forty feet above the latter) are placed in working communication by the raising and lowering of pontoons with vessels afloat within them. I am satisfied that by modifying the plans of tliese hydraulic operations and greatly aug- menting their scale, and by interposing railroad communication be- 21 tween the seas to be connected, ships can be conveyed across inter- vening land, and much less expensively than by canal, where the distance to be traversed is great. E. J. REED." The following is from one of the oldest and ablest con- structors in the United States nary. Orange, New Jersey, Jan. 33, 1881. Mr. James B. Hads. Dear Sir : I have Avatched with great interest the efforts you are making to establish communication between the Gulf of Mexico and the Paciiic Ocean for sea-going vessels by means of a ship railway. In this effort I sincerely hope you will have success. With a sub- stantial road-bed for your railway, on the easy grades across Tehuan- tepec, which, I understand, do not exceed one or two feet in the hundred, there can be no mechanical difficulty in the way of trans- porting loaded ships by railroad with entire safety to the vessel^ whether they be built of wood or iron. With a sufficient number of rails on the road-bed, and a sufficient number of wheels to distribute the weight in the manner proposed by you, the transportation of a fully -loaded vessel without straining her hull will be assured. The speed with which you can move the vessel will depend entirely upon the size and number of your locomotives. What weight and power they should possess to move the largest vessels used in commerce at a speed of ten miles an'hour, over your maximum grades, is a matter which experienced railroad engineers will be able to determine with great accuracy. The ship-railway plan possesses the advantage of more rapid tran- sit for the vessels, and its capacity could easily be increased to meet the future wants of commerce. Very truly yours, EDWARD HARTT, United States Namal Constructor. The following is from another United States naval con- structor, of recognized ability and talent. Philadelphia, February 7, 1881. James B. Eads, JSsq., Washington, D. C: Dear Sir : Having carefully examined the plans and papers per- taining to your proposed ship railway across the Isthmus of Tehuan- tepec, I do not hesitate to to say that in my judgment there will be no difficulty whatever in transporting, in the manner you propose, any properly built vessel with absolute safety. Your railway will possess one quite important advantage over the ordinary canal, and that is, that the vessel's bottom, propeller, etc., can be examined and if necessary cleaned in transit, and repairs of 22 whatsoever nature can be made wherever it is practicable to con- struct suitable sidings, transfer tables, shops, etc., more economically, other things being equal, than in a dry-dock. Your well known skill as a scientific and practical engineer is a sufficient guarantee that this great undertaking will receive careful consideration in every detail, and that it will be a success, both as an engineering achievement and a financial investment. Wishing you all the success possible, I remain Your obedient servant, H. L. FERNALD. Naval Constructor, U. S. N. The following is from the President of the Mississippi River Commission : New York, January 21, 1881. James B. Eads, Esq., Washington, D. G. : Dear 8ir : I have to acknowledge the receipt of your note of the 17th instant, relating to your project of a ship railway across the Isthmus of Tehuantepec. In my judgment the construction of a ship railway across the Mexi- can isthmus, in general accordance with your plan, is not only feasi- ble as an engineering problem, but the successful maintenance and operation of such a road is entirely practicable as a business enter- prise. This assumes that your engineers will find a route of suitable alignment and grades, a question of ijrompt and e&sy solution, upon which your information is much greater and better than mine. In pushing forward this great project I wish you that full jueasure of complete success which your will, energy, and prestige as an en- gineer are so well calculated to command. Very respectfully, your obedient servant, Q. A. GILLMOEE, lAeut.-Ool. Engineers, Brevet Major- Gen. The following is a letter written by Mr. Henry Flad, a distinguished civil engineer, president of the board of publi c works in St. Louis : To E. W. Pox, Esq., Publisher "Exporter and Importer,''^ St. Louis, Mo. . Dear Sir : In reply to your request that I give my views in regard to the ship railroad proposed by Captain James B. Eads, I beg to state my opinions : First. That the first cost of the construction of a ship railroad will not be one-fourth of that of a ship canal. Second. That a ship railroad can be constructed in probably one- third of the time required to construct a canal. 23 Third. That ships can be transported on such a railroad with ab- solute safety, and with the same dispatch as through a canal. Fourth. That the cost of maintenance will be less for a railroad than for the canal. Fifth. That although the cost of transferring ships by railroad will exceed that of passing them through a canal, the difference will be insignifioant compared with the saving of interest on the first cost. Sixth. That the ship railroad will, therefore, offer a safer and better investment for capital. Very respectfully, HENRY FLAD, G. E. iVlr. 0. Chanute, the accomplished and experienced civil engineer, who is superintendent of the Erie railway, says in a letter to me, " I am much pleased to find in this morning's Tribune your very able and clear presentation of a scheme for a marine railway across the isthmus ; the rather as I gave some attention to the subject myself nearly a year ago, and reached conclusions almost identical with yours, as to the feasibility and general features of the project * * * I see no reason why the railway should not be worked at ten miles per hour, and assuming it to be sixty miles long, why a steamer cannot be transferred from ocean to ocean in twelve hours." The following is a letter addressed to me by Commodore H. W. Shufeldt, U. S. IS., the accomplished officer who sur- veyed the Isthmus of Tehuantepec : Washington, D. C, Jan. 31. Mr. James B. JSads, Wa,sliington, D. C: Deae Sir : I forward to you with great pleasure, an extract of a letter from Commodore Farquhar, commanding United States ship Quinnebaug, at present at Alexandria, Egypt. " I am of the opinion that Tehuantepec possesses the best route for transit. I do not see why a railroad, capable of carrying a ship could not be built, and why the long slopes of our route should not be best. The fact of a harbor twenty-five miles long, on the Atlantic side, is of the utmost impor tance, more so than the one on the Paoifio shore, because that is almost always a weather shore in that latitude." I send you the extract as. a disinterested opinion of an accomplish- ed naval officer, not only as to the advantages of the route of Tehuan- 24 tepee, but as to tlie practicability of a ship railway across the Isth- mus. Very truly yours, R. W. SHDPELDT, U. 8. N. The well-known and able civil engineer, Colonel C. Shaler Smith, in a letter last year, said of the ship-railway, to the editor of the Exporter and Importer : " The engineering problems involved have all been solved on a smaller scale, in the construction ot various works in this country and in Europe, during the past thirty years, and the adaptation of these tried and proved principles of mechanical design to the case in hand is by no means difiicult. ***** " It wdl be a serious reflection on the enterprise of American cap- italists, the science of American engineers, and the patriotism of our statesmen, if foreign capital and foreign skill are to perform the work of severing our continents and then pocketing the profits of an enter- prise most of the cost of which must eventually be paid by our citi- zens in the shape of tolls upon our bi-ooeanic coasting trade." The following is from a member of the Mississippi fiiver Commission, formerly State engineer of Louisiana, and an engineer of acknowledged ability : New Orleans, Feb. 9. 1881. Dear Captain : Your letter of February 3rd, in answer to mine is just received after "'accidents by flood and field." The most^terrrific gales on record have destroyed many miles of our eastern railroad connections. I wish we had as stable a transit as your inter-oceanic railway project promises to give. I have followed carefully the de- velopment of the designs for this enterprise with increasing confi- dence in their practicability and correctness. It seems to me to have the great merits of excluding the necessarily uncertain elements in the estimate for any canal; of relying upon the experience of success- ful engineering works differing from this only in magnitude ; of avoiding a direct and dangerous conflict with natural obstacles such as the damming or diversion of water courses, the control of floods, &c.; of latitude in choice of location resulting in stability and econ- omy ; of facility and rapidity of construction maintenance andrepair, and of an easy extension of capacity proportioned to an increased trade. These points together with its extremely favorable geograph- ical location give the ship-railway, in my judgment, a decided advan- tage over other plans for isthmus transit. I shall impatiently wait for the first through train. Very truly, B. M. HABROD. 25 The following is from Mr. T. C. Clarke, of the firm of Clarke, Reves & Co., one of the most able and successful railroad and bridge engineers in the United States : " I am desirous that my opinion should be put on record that your ship railway is piatticable to construct, and can be maintained as easily as any other railway having as large a tonnage ; aud that ves- sels ol four thousand tons can be carried across without injury to themselves or their cargoes." The following is from Gen. G-. T. Beauregard, formerly a member of the United States Corps of Engineers : New Orleans, Jmmary 35, 1881. My Dear Sir: I take pleasure in communicating to you in as few words as possible my views relative to the practicability and economy of a ship railway across the Isthmus of Tehuantepeo. I feel no hesi- tancy iu saying tliat I see no difficulty in constructing a railway strong enough to carry out the object referred to. It is only a c^ues- tion of the strength of the cradle to hold the ship aud the division of weight on a sufficient number of rails and wheels, which can certainly be accomplished hy any engineer of ability and ingenuity. As to the danger a loaded ship would incur in being transported on a smooth and well-built railway, it is all imaginary, for it would be well braced and cushioned in a strong car or platform, supported by spiral steel springs on a very large number of wlieels which, being- separate from each other, could be easily replaced if broken during the trip. Moreover, the breaking of one or a few of them out of so many would not endanger the rest. With regard to the economy of such a sliiiD railway I would remark that the tonnage carried over it being moved entirely by machinery, and the ratio of paying cargo to dead weight being much greater than on ordinary railroads, the cost of operating such a lailway must be much less. The cost of maintenance shovild be also less in pro- portion, for the road would be substantially built and short in com- parison to the amount of tonnage carried over it. Moreover, the machinery used would be simple and substantially made. It is there- fore safe to assume that the current expenses and those of mainte- nance would not exceed 50 per cent, of the gross receipts, which would be more profltable than from a canal costing probably two or three times more than a ship railway, and leriuiring three or four times longer to build, thereby increasing greatly the amount of inter- est alone on the actual cost of the canal. A ship raslway has other important advantages over a canal, such as the facility with which the number of trucks could be increased to accommodate the demands of commerce ; the rapidity of transit and the greater number of vessels per day that could be transported than through a canal ; the practicability of building a railway where a 26 canal would be impossible ; the ability of estimating correctly for the first, while the latter if partially built under the water or liable to be submerged or interrupted by water would be very difficult, if not impossible, to be estimated for as to cost and time of completion. 1 am yours very truly, G. T. BEAUREGARD. Mr. J. J. Williams, a very able engineer, with long ex- perience in railroad building, who has made a number of surveys for railroads on the Isthmus of Tehuantepec, says: "I have been greatly interested in your proposition to construct a ship railway across the Isthmus of Tehuantepec for the trans- portation of the largest class of merchant vessels. Having carefully examined the details of your plans for accomplish- ing the object, and being thoroughly familiar with the to- pography of the Isthmus, I desire to express my full convic- tion of their entire practicability." Mr. E. L. Corthell, the engineer of the bridge across the Mississippi River at Louisiana, and of the Sny Island Im- provement Works, and who was resident engineer at the Jetties until their completion, writes as follows: "My studies of the engineering difficulties convince me that they can be easily overcome, and I believe the ship-railway for the trans- portation overland of the largest vessels can be made entirely successful, and that ships can be transported more rapidly by the railway than by the canal, and with equal safety." The following is from one of the engineers sent by the United States to Europe to investigate the improvement of the mouths of rivers there, and to report upon the jetty sys- tem, lie is likewise an experienced railroad engineer : Richmond, February 5, 1881. James B. Eadu, Esq. My Dear Sir: AVhy should not your ship-railway be practicable? Ships have been hauled on marine railways for I know not how many years, and the liauling of larger ships a longer distance is only a de- velopment or expansion of this practice, as the steel roadway worked by locomotives is the developemeut of the tramway or the old incline worked by stationary power. The idea is worthy of the age, and to make it a success you have simply to improve and expand tlie details of the old marine railway 27 aud make it more perfect. I have the greatest confldence in your ability in this particular, and hope you will have the opportunity to demonstrate it. Very truly yours, II. D. WHITCOMB. Civil EiKjineev in charge of Impi-ovement of James Biver. The following is from the engineer in charge of the im- provement of the Missouri River : United States Engineer's Office, 1351 Washington Avenue, St. Louj.s, January 31, 1881. Dear Captain : I have watched with much interest the develop- ment of your plan for the construction of a ship-railway across the Isthmus. The project has great and obvious advantages to recom- mend it ; and from an engineering point of view, it is, in my opinion, perfectly practicable. The various operations contemplated are con- stantly being performed, on a small scale at least, at all the great sea- ports of the" world, and any difliculties whicli might attend their ex- tension to the scale you propose, could, I think, be readily mot by suitable mechanical devices. The construction, maintenance, and operation of the railroad are quite within the resources of our pro- fession. With my best wishes for your success, I am. Captain, Yours very truly, CHAS. E. SUTER, Major of Engineers, U.^ti. A. Capt. James B. Eads, Washington, D. v. The City Engineer of Pittsburg, a gentleman who has had an extensive practical experience in engineering works, has sent the following: City Engineer's Office, Pittsburg, Pa., January 31, 1881. James B. Eads, Esq. : Dear Sir : I heartily indorse the project of a ship railway across the " cord of the continents " in preference to a canal. My reasons are that it will not cost more than about one-third as much as a canal with locks ; it will not require more than one-half of the time to con- struct it that will be consumed in the construction of the canal ; it will cost less to maintain and operate it than a canal, and the facili- ties of transportation can be much more readily, cheaply and advan- tageously increased on the railway than on a canal when the neces- sities of commerce require it, and the very "leviathans of the mer- chant marine " can be transported more easily and with as much 28 safety on the railway as through the canal, and without any break of cargo or any danger thereto. It would extend this letter to too great a length to give figures to ratify the statement herein made, but they will substantiate it to the full, and I further state that if the profits of the "canal investment" would amount to "five per cent.," those of the railway project would amount to not less than twenty per cent, on the investment, and very probably more; yea, it would be a paying investment under circumstances of disastrous loss to the canal projectors; therefore, in view of all the considerations con- nected therewith, I have come to the conclusion above embodied. Hoping that you may succeed in procuring the necessary encourage- ment and substantial aid that the importance of the project demands, so that you may be enabled to demonstrate practically the truth of the above and verify the assertions made, I am, most respectfully, etc., H. DEMPSTEK, Gity JSnrjineer. Th9 following is from the distinguished civil engineer w^ho is now Dean of the Department of Civil Engineering in Cornell University. He was the Chief Engineer of Commo- dore Shufeldt's surveying expedition in 1872 : Depaktment of Cia'il Engineering, Cornell University, Ithaca, N. Y., February Uh, 1881. Capt. James B. Eads: Dear Sir : My surroundings during the past ten years have cut me out from taking active part in the discussions upon trans-isthmian routes ; but I have never lost my great interest in this matter, nor doubted what I have put on record several times, Yiz : "Tehuantepec will be open to the world earlier than any other route." This con- viction is owing to the fact that I have made a thorough, disinter- ested, honest and patriotic study of nearly all the bearings of tliis important question, and my conclusions are almost mathematically correct. When vour Ship Kailway project appeared and was ridi- culed by inconsiderate engineers, I made computationswliich proved conclusively to my mind that the " Great Eastern" could be carried safely overland upon rails, with less strain to her timbers than in any of her sea voyages. There can be no difficulty about wheel-base enovigh to support a weight that has been supported in the ways of any dock ; or ab(uit rails upon which to roll the weight ; or power to draw it at any desirable speed ; and all this, with absolute safety to the keel, ribs and joint points of any vessel (yet built) and trans- ported out of water. No bridge tliat is now in use undergoes the beudings, twistings, and shaking that any vessel is bound to with- 29 stand, upon a rongh sea, ■without opening a seam ; and yet, no one doubts the practicability of transporting a truss by rail. In fact, every railroad car is a clumsily made truss. I am well acquainted with the data obtained, and supposed to have been obtained, to within a few years, upon the subject ; and I am pr-rfectly familiar with every possible point through which a canal could be located at Tehuante- pec. I am sure it is easy to prove that all routes outside of the &ulf of Mexico will be detrimental to the most vital interests of the United States and a source of great danger to our national stability. But the people at large have not had a fair opnortunity to study this question so as to place more faith upon its merits than upon the men advocat- ing the routes proposed. Time must take its course to allow the spe- citic truth of this case to survive the machinations of partisanship. But the time has now arrived for effective work and determined ac- tion ; and I thank God that your brain, reputation and sledge-hammer has been set to work to batter the Isthmus into an American high- way. I can assure you, upon knowledge of every inch of the ground, that you will find no difficulty about curves, grades, or bridges. The ascent of the Atlantic slope will offer no more difficulties than the Hudson River R. R. ; and, as on the Pacific side, either one of the three passes in the neighborhod of Tarifa or Chivela will allow of no steeper grade than 25 to 35 feet per mile to bring you down to the Pa- cific plains. The ground offers you 50 miles to get down in, and as much more as you may wish by following the hillside. All the bridges required will be of comparatively short spans. You wiU fiud very little anxious work on either terminal harbor, very little tenta- tive work being required, and permanence without ulterior compli- cations will reward almost any kind of attack. The drainage of the works; building materials, (including excellent, cement-yielding, dolomitic limestone, between San Miguel and Tarifa;) abundant native labor ; a remarkably healthy climate, &c., will be all you may desire. I think the estimate of tonnage upon which you base your reasons for the safety of the Government in guaranteeing three per cent, serai-annual dividends is quite modest, since in spite of official statis tics I believe the road will handle 30,000 tons daily very soon after its being opened. The discussion of this question is long, and my letter is growing likewise long. I write to you to give you encouragement to push on this matter with all your might. I have no personal motive to subserve ; my field is here for a life time, which I fear will be too short for my pur- pose. Therefore, if I have bothered you, you at least can say this is a case of disinterested boring. If I can be of any service to you command me, and I will be glad to furnish any data upon unpublished notes or surveys I have; and 30 be sure you have my most sincere wishes for the happy issue of your undertaking. Very truly yours, E. A. FUEKTES. In discussing the merits of the several Isthmian routes before the Merchants' Exchange, in St. Louis, pending the unanimous adoption by that body of resolutions recommend- ing the favorable consideration of the Ship Railway to the Grovernment, Captain Silas Bent, a gentleman who has de- voted much study to the winds and currents of the ocean, and who was formerly an officer of the United States Navy, made the following remarks : " Merc statements of the difl'erenoe in miles is a very inadequate measure of the difference in time that would be occupied by sailing- vessels in making these several passages, and when we consider that three-fourths of the ocean commerce of the world is carried in sail- ing-vessels, you can see what an important factor this question of sailing-time becomes in the solution of the problem before us. " The northeast trade-winds which extend across the Atlantic are so broken and interrupted when they encounter the West India Islands, that they never penetrate the Caribbean Sea ; but the north- west portion of them, however, do extend into the Gulf of Mexico, and often so far down as to reach well toward Tehuantepec, so that whilst in the Gulf winds are always found, yet the Caribbean Sea re- mains a region of almost relentless calms. ^ "Nor is this all, for the mountain ranges, extending the length of the Istlimus of Panama and through Central America, offer a still more formidable barrier to tlie passage of these winds, thus throwing them still higher into the upper regions of the atmosphere, and ex- tending these calms far out into the Pacific Ocean, on the parallel of Panama, with lessening width, for fifteen or eighteen hundred miles to the northwest, along the coast of Central America. " This whole region of calms, both in the Caribbean Sea and in the Pacific Ocean, is so well known to navigators that sailing-vessels always shun it, if possible, though they may have to run a thousand miles out of their way to do so. " This absence of wind of course leaves this vast area exposed to the unmitigated heat of a torrid sun, except when relieved momenta- rily by harassing squalls in the dry season, and by the deluging rain- falls of the wet season. With these meteorological facts in view, let us now suppose that the Lesseps Canal at Panama, and the Eads Railway at Teliuantepec are both completed and in running order ; then let us start two sailing-ships of equal tonnage and 31 equal speed from the moutli of the Mississippi, with cargo for China, one to go by the way of the Panama Canal, and the other by the way of the Tehuantepec Railway, and I venture to affirm that by the time the Panama vessel has cleared the canal and floats in the waters of the Pacific, the Tehuantepec vessel will have scaled the Isthmus and be well on to the meridian of the Sandwich Islands; and that before the former vessel can worry through the fifteen or more hundred miles of windless ocean before her, to reach the trade winds to the westward of Tehuantepec, the latter will have sped five thou- sand miles on her way across the Pacific, and be fully thirty days ahead of her adversary. For it is a fact worth mentioning liere, that the strength of the northeast trade winds in the Pacific, as well as the maximum strength of the northern portion of the great equato- rial current in that ocean, are both found on or near the parallel of latitude of Tehuantepec, the former blowing with an impelling force to the westward of ten or twelve miles an hour, and the latter with a following strength of three or four miles per hour." To my mind there is no difficulty in the way that cannot be readily overcome by engineering and mechanical skill, neither in the con • struction of the road nor in the necessary machinery to handle and carry vessels of any size and of and weight across the easy gradients of the Tehuantepec Isthmus. And I further believe that such a railway can be built at half the cost and in half the time — yes, in one- third the time — that any canal can be constructed ; and that while the railway, for many reasons, would be of greater practical benefit to the commerce of the world at large than a canal, it would be in that locality of immeasurably greater advantage to both the commerce and the political well-being of onr own country.
