LOUIS, MO. ; I/EVI90N & BLYTIIE STATIONKBY COMPANY PHINT. 1880. ADDRESS. Mr. 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 importance. Any proj ect which promises cheap and quick transportation for the products of your fertile soil, 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 your 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 Bast, 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 enormous 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 is 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 are 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 will 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 6 per ton. Now, as the ship 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 miles, 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 Nicaraguan 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 which 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 sails 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 carry 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 Railroad 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 laden 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 w.ork would have to be upon a very large scale. The road-bed must be a solid one, and all machinery employed of a character consistent with the great weight of the vessels to be 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 an ordinary first-class freight engine while at rest. One of the first objections presented to the mind by this plan is the great weight to be borne by the road bed. A cradle for a ship a'nd 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 ties 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 ligence ; 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 called 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 affecting 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 will 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 will 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. If 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 emphatic 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 could 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 full 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 canal 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 tell 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 you 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. De Lesseps1 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 the evils which 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 Nicaraguan 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 will 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 Graytown 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 of 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. But 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 will 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 that 1 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 effort in behalf of the Jetties, was addressed to me by a large number of the merchants of that city. Convinced that these people 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 efforts, arid 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 seen whether my efforts will be hampered by your oppo sition or encouraged by your aid and influence. 08540 4516 ¦ ¦ ¦ ¦¦ ¦
