"The experience of the world has shown that nations do not become commercial or manufacturing, so long as the products of the soil are sufficiently abundant to yield them wealth; and, hence, it may be reasonably inferred that the carrying trade to and from South-America will, if proper measures be taken, fall into the hands of American ship-owners. By way of ascertaining what the extent of this trade will be, if reference be had to the interior or back country as the standard of the commercial resources furnished by rivers, it will be found that the total area drained by the rivers of the world is as follows:

Sq. Miles.
Europe, emptying into the Atlantic,532,940
Africa, emptying into the Mediterranean,198,630
Total Old World,1,731,570
Asia, emptying into the Pacific,1,767,280
Asia, emptying into the Indian ocean,1,661,760
Total Asiatic,3,429,040
North-America, including St. Lawrence and Mississippi emptying into the Atlantic,1,476,800
South-America, emptying into the Atlantic—
Amazon and its confluents,2,048,480
La Plata and all others,1,329,490
Total South-American3,377,970
Total American to the Atlantic,4,854,770

"From the above statement it will be seen that the proposed line of steam communication will bring within thirty days of each other, the commercial outlets of navigable streams which drain a back country greater in extent than that which is drained by all of the navigable streams which empty themselves into the Atlantic, the Pacific, and the Indian oceans, from those portions of Europe, Asia, and Africa, which are accessible to American commerce. Settlement and cultivation will, in the course of time, make these American river basins as rich in products as those of the old world.

"The question next arises, who are to be the carriers of the trade which is hereafter to spring out of these American river basins, the English or the Americans? If Great Britain be suffered to monopolize commerce as she has heretofore done by her steam navigation, her people will enjoy this great boon; but if, on the contrary, the United States take advantage of circumstances as they should, the prize will be won by Americans."

"Your Committee would remark, in concluding this Report, that, regarding as they do the existence and rapid extension of the system of ocean mail steam navigation, as absolutely essential to the dignity and permanent prosperity of the country, and as the only means, consistent with the genius and policy of our free institutions, of acquiring a maritime strength, which, by keeping pace with the improvements of the age, shall place us upon an equal footing with other civilized countries of the world, without the necessity of an overgrown and expensive naval establishment proper, in time of peace, they would feel themselves derelict in the performance of their duties, did they not recommend the measure, with the earnestness which its importance demands.

"Circumstances indicate, with a clearness not to be misunderstood, that in any future struggle for superiority on the ocean, the contest will be decided by the power of steam. With a view to this result, England has applied herself with even more than her wonted energy to the construction of a regular steam navy which shall be superior to all others. The number of ships which Great Britain has of this kind, is at present two hundred and seventy-one, and there are no less than nine royal war steamers in progress of construction, to say nothing of the mail and other steamers which are being built. The course thus pursued by the great commercial rival of the United States, renders a corresponding energy and activity on our part absolutely necessary, in a national point of view; a steam navy must be provided for future emergencies in the way proposed by the Committee, or war steamers must be built at an enormous outlay of public money and kept ready in the navy yards, or in commission, at an expense which is appalling to every lover of judicious economy, or the stripes and stars of our country, which have heretofore floated so triumphantly on every sea, must grow dim, not only before the 'meteor flag of England,' but the standards of the secondary powers of Europe. If members of Congress are prepared to adopt either of these latter two alternatives, let them say so, and let a system which promises, under an honest and faithful discharge of duty on the part of the executive branch of the Government, to realize the most sanguine expectations of its friends, be at once abandoned. Let Great Britain be again the guardian of our commercial interests and the beneficiary of American trade. Let the Liverpool, Bremen, Havre, California, and other lines, which have furnished twenty-four as noble sea steamers as ever floated, be abandoned to their fate, and let the Cunard line and other British steam mail lines and royal steamers supply their places on the Atlantic and Pacific oceans, and our Southern seas.

"Your Committee would again repeat that the question to be considered is not one of mere dollars and cents, or whether certain individuals are to be sustained, or not, but one of infinitely greater consequence—whether this proud republic shall now and hereafter exist as a power competent to maintain her rights upon the ocean. The present condition of political affairs in Europe is such as, in the opinion of many, to threaten a general war among the nations of that quarter of the globe, and the United States should stand ready, and able too, to protect the rights of her citizens upon the ocean, in such an event. Were such a crisis to take place to-morrow, or the next year, or within the next five years, is the country prepared for it? The steam navy proper amounts to sixteen steamers of all classes, which, together with the twenty-four ocean mail steamers in the employ of the Post Office Department, would give us a steam naval force not exceeding forty in all. Is this the position we should occupy, while Great Britain has at command upwards of three hundred war and mail steamers? France has, it is believed, upwards of a hundred, and the secondary powers of Europe have naval steam armaments in proportion, most of them exceeding our own. This question will be decided by the continuation or rejection of the system under consideration, which, with all the difficulties attendant upon new enterprises and under the most embarrassing circumstances, has gone very far to sustain itself, and promises, at no distant period, to become a source of large revenue to the Government, and incalculable commercial advantages, pecuniarily and otherwise, to the country."

The following is copied from the Report made by Mr. Rusk in 1850, and published in Special Report of the Secretary of the Navy, 1852. Speaking of the services of the mail steamers in our system of defenses, the Report says:

"The truth is, that, in the opinion of your Committee, the temper of the times requires that we shall keep pace with the rapid improvements of other nations in their commercial and military marine, and that the only choice is, whether it is to be done by constructing vessels for the packet service, at a boundless expense to the Government, or by aiding private enterprise, and thus not only eventually avoiding expense, but adding largely to the revenues of the country. It will be seen from the above extract from Mr. King's speech, that, in the course of five years, the balance in favor of the Government from the Cunard line alone was $5,286,000. The New-York and Liverpool and Bremen lines will come in for a large, if not by far the greater, share of the postage and freightage heretofore enjoyed by the Cunard line; and the line to Chagres, for the advantages that have, up to the time of its partial commencement, been in the exclusive possession of the British packet establishment in that direction. Nor are the freightage and postage moneys the only sources of profit. In proportion to the increase of these facilities will be the extension of trade, and consequently the Government will receive the duties payable upon all foreign merchandise brought into the country. Besides, persons in transitu will leave much money in our cities and along their routes, to say nothing of the porterage and costs of transportation of goods. To benefit our people is to benefit our Government; as the more we enrich the former, the more able are they to contribute to the support of the latter.

"To construct ships and keep them in our navy-yards, subject to the injuries of time and casualties, does not consist with the notions of the American people, on the score of economy; nor is it in accordance with received opinions in regard to the propriety of placing excessive patronage in the hands of the General Government. At the same time, it is in perfect unison with the spirit of our free institutions that the arts of peace shall be made tributary to the purposes of defense, and the same energies which extend the commerce and manufactures of our country shall, in the event of necessity, be capable of being made use of for our protection. While the crowned heads of the Old World keep in constant pay vast armies and navies sustained by the heart's blood of the oppressed people, for the protection and preservation of their unhallowed power, it is the proud boast of our country that our soldiers are our citizens, and the sailors, who, in time of peace, spread the canvas of our commercial marine throughout the world, are the men who, in time of war, have heretofore directed, and will continue to direct, our cannon against our foes."
