Believing that no further arguments or facts are necessary to show that a rapid steam mail marine is desirable and essential to the successful government of the country, to our foreign commerce, and to the growth of individual interests and a general prosperity of the people, I shall now make some few inquiries concerning the Commercial Capabilities of steam, as the most effective agent for the rapid transit of the ocean, and the most expensive agent for the transport of goods. After this, it will be necessary to examine into the Cost of Steam, as a subject closely allied to its general capabilities.
Whatever may be said of the wind as a cheap agent of locomotion, this much may be safely predicated of steam vessels for the mails; that their time of departure and arrival has an absolute fixity which is attainable by no other means, and which is highly conducive to the best interests of all those for whom commerce is conducted. No reasoning is necessary to show to the man of business, or even to the pleasure-seeker, the importance of approximate certainty as to the time when the mail leaves and when he can receive an answer to his dispatches. He may not be able to give clearly philosophic reasons for it; yet he feels the necessity in his business; and it certainly relieves him of many painful doubts, if nothing more. Uncertainty in commercial operations is always hazardous and costly to the great mass of the people, who as a general thing pay more for whatever they get, on the principle that we seldom take a venture in an uncertain thing unless it holds out inducements of large profit, or unless we get a high price for guarantying it. So in commercial correspondence, which constitutes the great bulk of the ocean mails. Let uncertainty prevail for but three or four days beyond the time when we should have news from abroad, and every body is in doubt, every body speculates, and in the end every body is injured.
Nor is this certainty in the time of arrival and departure of the mails more desirable than their speed. The common sense of the world has settled down upon the necessity of rapid mails; and all of the ingenuity of the age is now taxed to its very highest to secure more speed in the transmission of intelligence. Many interests demand it. Money, which represents labor, is continually lent and borrowed in bills of exchange, acceptances, deposits, and in actual cash sent across the seas. The length of time for passing the bills and correspondence, or the specie itself, thus becomes an exceedingly important item to those who are to use them, and consequently to the ultimate consumer for whom they are conducting the commercial transaction. What community would to-day tolerate the idea of sending three millions of dollars per week, and five millions of credits between England and the United States on a sailing ship of whatever quality, with the probability of keeping it lying unproductive on the ocean for thirty days? Extend this to weekly shipments of the same amounts, and have at one time on the waters between the two countries twelve million dollars in specie and twenty in credits, tossing about the ocean, unproductive and unsafe, and entailing all of the evils incident to the uncertainty as to the time when it will arrive. But if this is not sufficient, extend the inquiry to South-America, and China, and India, and see how enormous and useless a waste of money and interest is incurred in the many millions which by sailing vessels and slow steamers is fruitlessly gilding the ocean for months. Money is too valuable and interest too high to keep so many millions of it locked up from the world. At two and three per cent a month, the nation, or, what is the same thing, its commercial and mercantile classes, as representing the producing, would soon become bankrupt.
The only avoidance of these evident evils is in a rapid transmission of the mails, specie, and passengers. And herein consists the chief value of the rapid ocean steamer. It is an important case which the Telegraph, with all of its benefits, can never reach. It can never transmit specie; neither the evidences of debt nor of property. The voluminous mails, with all of their tedious details, upon which such transactions depend, must go and come on steamers, and on steamers only. They have the certainty, which will satisfy men and prevent speculation, gambling, and imposition; they have the speed, which shortens credit, keeps specie alway in active use, and enables commercial men to know, meet, and supply the wants of the world before they become costly or crushing; and they give a rapid and comfortable transit to passengers, who can thus look after their business, and save much to themselves and to the producer and consumer. Compared with sailing vessels their efficiency is really wondrous. Foreign correspondence was formerly very limited, and the interchange of interests, feelings, and opinions was slow and tedious. Each nation depended solely on itself; and instead of the brotherhood now prevailing, communicated through the costly channels of war, by messages of the cannon, and in powerful, hostile fleets. But the foreign correspondence of the world is really enormous, and rapidly increasing, since the introduction of ocean steamers; and no one will say that they have had a small share in producing that fraternal international spirit which is now so widely manifested in Peace Congresses, Congresses of the Five Powers, explanations, concessions, and amicable adjustments of difficulties. The peaceful influences and the civilization of the times are but another comment on the capabilities of steam.
There are also certain classes of freights which steam is better calculated than sailing vessels to transport; certain rich and costly goods which would either damage or depreciate if not brought speedily into the market. There are many articles also, as gold and silver ware, jewelry, diamonds, bullion, etc., and some articles of vertu as well as use, which are costly, and have to be insured at high values unless sent on steamers; and which consequently can pay a rather better price. As in the case of specie, they are too valuable to be kept long on the ocean; but in the general traffic of the world there is so little of this class of freight that steamers can place no reliance on it as a source of income. These freights have abounded most between France and England and the United States. This is the principal reason why the New-York and Havre line of mail steamers has run on so unprecedentedly small a subsidy; a sum not more than half adequate to the support of a mail line but for that class of freights. The Cunard line has also derived a large sum of its support from the same source. All such articles passing by that line come from England, Ireland, and Scotland, where they are manufactured; and being shipped by British merchants, are given, as a matter of duty, to their own steamers. Another reason for the Cunard line getting most of those more profitable freights is that a steamer leaves every week; every Saturday; and shippers sending packages weekly are not compelled every other week to hunt up a new line, and open a new set of accounts, as would be the case if they attempted to ship by the Collins semi-monthly line.
These freights have hitherto proven a profitable source of income to that line. As there is no manufacturing done in this country for Europe, the Cunarders and the Havre as well as the Collins and Vanderbilt lines, have no freights that pay the handling from the United States to Europe. And not only has the Cunard line, by starting from home, taken all of these profitable freights from the Collins, but it has run a weekly line of propellers from Havre and taken the freight over to Liverpool free of charge for its New-York and Boston steamers, and thereby shared the freights and greatly reduced the income of the Havre line. There being a great superabundance of propeller stock in Great Britain, which can be purchased frequently at less than half its cost, and these vessels running the short distance between Havre and Liverpool very cheaply, (See pages 108-13,) the Cunarders have cut the Havre freights down from forty to fifteen dollars per ton, and sometimes for months together to ten dollars per ton. As a matter of course, this price would not pay the handling and care of these costly articles; but at fifteen dollars it enabled the Cunard line to fill their ships and derive some profit; as most of them, with the exception of the Persia, run slowly, use less coal, and have more freight room. All of these freights are, however, small in quantity, and not much to be relied on from year to year, as will be seen below, in consequence of the action of propellers.
There is another class of business which mail steamers can do at remunerating prices; but which is exceedingly limited anywhere, and not at all known on some lines. This is in Express packages. They pay a high price; but seldom reach more than three or four tons under the most favorable circumstances. In the early stages of the California lines, when there was a rush of travel to the gold regions, and a hurried transit required for a thousand little necessaries of life, the New-York and Aspinwall and the Pacific Mail Steamship Company's lines transported a large express freight outward at every voyage, amounting sometimes to two hundred tons; but the golden days of such cargo have long gone by, and California is now supplied like the rest of the world by the cheaper and more deliberate transport of sailing vessels; and the steamers are left to their legitimate business of mails and passengers. Taking together all of the classes of freights which steamers having mail payment are capable of transporting, they amount at present to but an insignificant part of the income by which these steamers can be run. During the last six years these freights have reduced more than one hundred per cent; and goods which were then profitable to the steamer, are now taken only "to fill up." And the chief reason for this reduction arises not so much from competition between the steam-lines, which well knew that they could not transport these freights when reduced to the present low prices, but from the introduction of a large number of propellers, some of which were originally designed for this species of trade, and many others which were built during the war in the Crimea for the transport of troops. These ships were never prosperous anywhere, and are in nearly all cases at the present found in second hands; the original proprietors having lost a large share of their investment. Thus, purchased cheaply, and running with simply an auxiliary steam power, and making the passages but little shorter than the sailing vessels, and not even so short as their best passages, they have but little more daily expense than the sailing vessels, with all of the deceptive advantages of being called steamers. They thus get these better freights and a large number of immigrants, which with small interest on prime cost enables them to live.
Paradoxical as it may seem, there are yet some cases, even upon the ocean, in which steam can transport freight cheaper than the winds of heaven. And this species of trade constitutes one of the best capabilities of steam power applied to navigation. It is not in the long voyage between Europe and America, or between the East and California, or yet in the far-off trade among the calms and pacific seas of the East-Indies and the Pacific Islands; it is not in the smooth, lake-like seas of the West-Indies, where there is no freight whose transport price will pay for putting it on and taking it off the steamer; nor in the trade of Brazil whence a bag of coffee can be transported five thousand miles to New-York nearly as cheaply as it can from New-York to Baltimore or to Charleston; but it is in the coasting trade of almost every country, where the voyage is short. In the trade between New-York and Baltimore, between Charleston and Savannah, between Boston and Portland, or between New-Orleans and Key West, or New-Orleans and Galveston, the small sailing vessels spend one half of their time in working in and out of the harbors. Sometimes they are two days awaiting winds, to get out of a harbor, two days in sailing, and two days again in making and entering their port of destination; whereas a steamer would make the whole passage in one day to a day and a half. Now, the distance actually to be run, and for which the steamer will be compelled to burn coal is not very great; but the trouble of working the vessel in and out, against adverse winds and currents, and amid storms and calms, is sometimes excessive, while the delay and cost are disheartening. They have also the trouble of warping into and out of the docks, which is not the case with steamers.
Thus, it frequently takes a week for a sailing vessel to do the work that a steamer will readily do in twenty-four to thirty-six hours. Say that it takes the sail four times as long as the steamer to accomplish a given voyage. To do as much business as the steamer would do in the same time, would require four sailing vessels; four times as many men as one sail requires, or probably twice as many hands in the aggregate as the steamer would have; and would incur at least twice the expense of the steamer in feeding them. Now, there is also a much larger aggregate sum invested in these four sail, and the owners pay a much larger sum of interest on their prime investment. Or, in other words, the steamer with but a few more men, but little greater expense in living, a small coal-bill, an engineer and firemen, and a prime outlay of not more than double the capital, will carry four times the freight and passengers, without incurring probably so much as three times the expense of one of the sail. After the prime cost the most important item of expenditure in one of these small steamers is the coal; but the distance run being so short, and getting into and out of the harbor and docks being so easy, the vessel does large execution at little expense. The two most essential benefits, however, of her short voyage are, that she is not compelled to carry much fuel, and consequently occupies nearly all of her space with freight; and that the prices of freight on these short voyages are much larger in proportion than they are on long voyages. Sailing vessels charge very little more for a thousand miles than they do for five hundred; but a steamer may have to charge nearly three times as much; especially if she run fast, consume much fuel, and occupy her cargo-room with coal. There are distances at which steamers, however large, can not carry a pound of freight; but occupy all their available space with the power that drives them. In these long voyages sail becomes much cheaper.
It is by no means essential that these small coasting vessels shall be propellers; for to acquire the same speed they expend the same power and have the disadvantage of being deeper in the water, and not being able to go into all harbors with much freight. They have also the advantage of carrying more sail, and being generally better able to stand coast storms than a side-wheel of light draught of water. They are not quite so expensive in prime construction, but generally require more repairs, and must be on the docks much oftener. They are, however, much better suited than side-wheel vessels to voyages where a medium speed is required, and where the steam can be used at pleasure simply as an auxiliary power. In such cases there is a profitable economy of fuel. But speed has generally been deemed essential in this country, and the side-wheel is everywhere used. But entirely the contrary is the case in Great Britain and France. There the coasting business is conducted by screws almost altogether; and the speed does not transcend the limit of economy and commercial capability. They distinguish between the extremely fast carriage of mails and passengers on the one hand, and freights on the other; and although they wish the speed and certainty of steam, yet it is not the costly speed. When they know that a given quantity of fuel will carry freight eight knots per hour, they would consider it wasteful and foolish to consume twice that quantity of fuel just to carry it ten knots; and more especially so, when, in addition to the extra quantity of fuel, they would lose just its bulk in paying freight room. England is thus employing most of her vast fleet of coasting ocean steamers in her own trade, or in the foreign trade lying within a few hundred miles of her ports. And the voyages being short, her coals being cheap and convenient, frequently not above three dollars per ton to the coasters, and in addition to this, the prime cost of these vessels being smaller than in this country, as both iron and labor are cheaper, she has found them very profitable at home, and is insinuating them into all the short routes wherever she can get a foothold. It was not until she attempted the same species of self-supporting steam navigation with distant countries, that her propeller system failed her and involved her citizens in loss. Meanwhile it is more than probable that within the next fifteen years we shall find five hundred propellers scattered along the coasts of the United States.
Notwithstanding the eminent capabilities of steam when applied to coast navigation, or to the fluvial navigation of the interior, it has failed to make the same triumphs in the carriage of freights and passengers upon the ocean. And it is not alone because the voyage is long and the freights low in price. Steamers carry freights up the Mississippi river two thousand miles from New-Orleans, and find it profitable. Some run even as high as three thousand miles up that river and the Missouri; a voyage nearly as long as to Europe, and make money by it. But the circumstances are very different. They do not leave the dock at New-Orleans with even more than enough fuel on board for the whole trip, as the ocean steamers do. If they did they could carry no freight. But they stop every twelve to eighteen hours and take on wood just as they need it, fifty to a hundred cords at a time; and instead of occupying all of their available room with wood, they have the steamer full of cargo, and have on board only fifty or sixty tons of fuel at a time, and only half that weight on an average. None of the best steamers on those rivers could take enough wood on board for the whole three thousand miles, even though they should not have a ton of freight. And compared with ocean steamers of the same engine power, they do not cost half of the money, I might say generally, not one third of the money. There is no reason, then, why these steamers should not carry large quantities of freight and make large sums of money by it. They have the great elements, fuel, freight capacity, and prime cost in their favor.
There is a large class of freights which are not transportable by steam on long ocean voyages under any conditions. We will grant that under the most favorable circumstances, where rich and costly articles are transported in small bulk, that propellers running at a low rate of speed, or just fast enough to anticipate sailing vessels, will make a living. But change the class of these freights into the great average class of those filling the thousands of sailing vessels, and deprive these screw vessels of an immense emigrant passenger traffic, and they would not pay their running expenses by fifty per cent. This style of freights, sailing vessels in their great competition have reduced to the lowest paying figure. The margin left for profit is so small that our ship-owners constantly complain that unless there are changes they must go into other business; and many of them say this honestly, as is shown by the hundreds of ships which of late years we can always find lying up, awaiting improvement in business. Now, let even the slowest and cheapest running screw vessel attempt to carry the same freights, to say nothing of fast side-wheel mail vessels, and we shall see against what odds the screw or other steamer has to contend. In the first place, her engines, boilers, coal, etc., occupy at least forty per cent of her total registered tonnage. Grant that the additional expense of a steamer over a sail, that is, wages for engineers, firemen, coal passers, etc., and finding the same in food and rooms, costs even no more than the loss of an additional ten per cent of her freight room. In other words, considering her steam machinery, fuel, extra expenses, etc., to be equal to half of her freight room, it is evident that she would carry only half as much freight as a sailing vessel of the same size, and that she would get but half as much money for it.
It is thus clear, I think, that there is a certain class of ocean freights which steam can not transport under any conditions so long as there are sailing vessels on the ocean; and in that class are comprehended all the great standard and staple articles of the world, constituting in sum seventeen twentieths of all the freight passing upon the ocean. This being so, it is utterly idle to suppose that steam in any form can take the place of sail upon the ocean, even though the present prices for the carriage of standard articles should increase three hundred per cent.
There are many considerations which affect this question. The ordinary average passages of the ocean on long voyages are now very rapid; and some of the clippers have attained a speed which no freighting steamer may ever be expected to do on the high seas. They do not maintain this high speed as an average, but it is sufficiently high for all of the ordinary purposes of transport in the standard articles of commerce, and where the business of the clipper is done by a fast mail steamer. There is no positive necessity for the speedy transport that some have attempted to give to articles, whose presence in the markets, as the ordinary supplies of life, to-day, next month, or a month later, is a matter of total indifference to every one except the ship-owner himself. It but little concerns the public whether a cargo of cotton, or beef or pork, or corn is one month or forty-five days between the United States and England, so that it is safe in the end. It is an annual production that must have an annual transit, and however unnecessarily fast we may become, we can not send more than one crop in the year. The world frequently becomes too fast in every thing; and crises, panics, and bankruptcies follow as legitimate consequences. When a fictitious value is given to every thing, and every globule of air which one has breathed comes puffing out, a splendid bubble, a magnificent speculation, and when men have to go so fast that they need a telegraph to ride them through the world lest they get behind the heated times, no wonder that the shipper can not sit quietly down in his office and wait thirty days for a load of corn to reach England, or a load of iron to appear in the harbor in return. And it does not matter to him that it may not be used there in six months. He wishes to finish the "operation," to close up the "transaction" before he goes up town in the evening.
There is a rational distinction between the necessary and the unnecessary which we must learn to make, and a limit which safety assigns to every operation. There are some things which must be done rapidly, and others which may be done at leisure. Between the freight cargo, and the correspondence which controls it there is a great difference. Rapid transport of letters, intelligence, and passengers, and leisure transport of freight, is the law of nature, and to attempt to reverse it is but to attempt that which will never be successfully done, simply because wholly unnecessary in any permanent economic sense. And not only is higher speed than that of clippers unnecessary in ordinary freight transport, but it is clearly impossible in any normal condition of trade. Circumstances may, and doubtless often will exist, which will require some sluggish article to be transported a long distance in a short time, as in the case of the famine in Ireland, and which may insure rates at which steam vessels can take small quantities of such freights; but such occasions will ever be accidental, and the support of vessels depending on them the questionable support of expedients, and capricious in the extreme. It will ever be just as impossible to hurry gross freights across the ocean in a healthy state of commerce as it will to prevent rapid mails, or forego the comforts of quick passenger transit.
To say nothing of a vessel which is half filled with its own power, attempting to compete, in the ordinary freights of the world, with one which fills every square foot with paying cargo, it is equally important that we should look at the question of fuel. The coals of the world are not so plentiful or so cheap that we should consume whole pits in a year in unnecessary and unproductive service. They are already beginning to fail in many parts of the world, or to the same effect, are mined and brought to market at such increasing cost, and applied to so many new purposes day by day, that in a few years the price will place them entirely beyond the reach of commercial purposes upon the ocean. It is contended, however, that the science of engineering is also rapidly advancing, and that we shall soon have some discovery by which we can have heat without fuel, and power without heat. But I have heard of those imaginary engineering hopes so long that I begin to believe them vague, and that we shall yet for a few generations measure the power applied by the number of pounds of coal consumed. From past experiences and present indications we can predicate nothing with more certainty of fuel than that it will indefinitely increase in price. I am satisfied, therefore, that with all of the capabilities of steam it can never be applied to general ocean transportation; first, because undesirable; and second, because impossible even if desirable. But to show more clearly that it is impossible, I will now make some inquiries concerning the cost of ocean steam, which is the cardinal point of interest in marine propulsion.
