That a more accurate, defined, and available knowledge than we at present possess, of the waters, islands, and continental coasts of the great Pacific and Southern Oceans, has long been desirable, no unprejudiced individual conversant with the subject, is likely to deny. A portion of the community unrivalled in activity, enterprise and perseverance, and of paramount importance both in a political and commercial point of view, has long been reaping a rich harvest of individual wealth and national honor in these vast regions. The Pacific may be termed the training ground, the gymnasium of our national navy. The hardihood and daring of that branch of our commercial marine employed in its trade and fisheries, have almost become a proverb. It is in this class we meet with the largest aggregate of that cool self-possession, courage, and enduring fortitude, which have won for us our enviable position among the great maritime powers; and it is from this class we may expect to recruit a considerable proportion of the physical strength and moral intelligence necessary to maintain and improve it. The documentary evidence upon which the report before us is based, forms an appendix to it, and is highly interesting in its character. It awakens our admiration at the energy and industry which have sustained a body of daring men, while pursuing a dangerous and arduous occupation, amid the perils and casualties of an intricate navigation, in seas imperfectly known. It enlists our sympathies in the hardships and difficulties they have combatted, places in strong relief the justice of their claims upon the nation for aid and protection, and shows the expediency of the measure which has at last resulted from their representations. The report itself is clear, manly, decided—the energetic language of men who, having examined the data submitted to them with the consideration the interests it involved seemed to require, are anxious to express their sentiments with a force and earnestness suited to their views of the urgent occasion and of the course they recommend.

It is a glorious study to contemplate the progress made by human industry, from stage to stage, when engaged in the prosecution of a laudable object. Little more than a century ago, only the crews of a few miserable open boats, too frail to venture far from land, waged a precarious warfare with the great leviathans of the deep, along the shores of Cape Cod and Nantucket—then occupied, at distant intervals, by a few inconsiderable fishing stations. The returns even of these first efforts were lucrative, and more appropriate vessels for the service were fitted out. These extended their cruises northward to Labrador, and southward to the West Indies. At length the adventurers, in vessels of yet greater capacity, strength and durability, crossed the Equator and followed their hardy calling along the Eastern Shore of the Southern Peninsula and on the Western and North Western coast of Africa. The Revolution of course operated as a temporary check to their prosperity, but shortly thereafter these dauntless mariners doubled Cape Horn, and launched their daring keels into the comparatively unknown waste beyond, in search of their gigantic prey. Since that fortunate advent, the increase in the shipping, extent, and profits of the fishery, has been unprecedented, and new sources of wealth the importance of which it is at present impossible to estimate, have been opened to us in the same quarter. The trade in skins of the sea-otter and seal, in the fur of land animals on the North West coast, &c. has been extensive in extent and avails. The last mentioned animal, besides the valuable ivory it affords, yields a coarse oil which, in the event of the whale becoming extinct before the perpetual warfare of man, would prove a valuable article of consumption. Of the magnitude of the commercial interest involved in different ways in the Pacific trade, an idea may be gathered in the following extract from the main subject of our review. Let it be borne in mind, that many of the branches of this trade are as yet in their infancy, that the natural resources to which they refer are apparently almost inexhaustible; and we shall become aware that all which is now in operation, is but as a dim shadow to the mighty results which may be looked for, when this vast field for national enterprise is better known and appreciated.

“No part of the commerce of this country is more important than that carried on in the Pacific Ocean. It is large in amount. Not less than $12,000,000 are invested in and actively employed by one branch of the whale fishery alone; in the whole trade there is directly and indirectly involved not less than fifty to seventy millions of property. In like manner from 170 to 200,000 tons of our shipping, and from 9 to 12000 of our seamen are employed, amounting to about one-tenth of the whole navigation of the Union. Its results are profitable. It is to a great extent not a mere exchange of commodities, but the creation of wealth by labor from the ocean. The fisheries alone produce at this time an annual income of from five to six millions of dollars; and it is not possible to look at Nantucket, New Bedford, New London, Sag Harbor and a large number of other districts upon our Northern coasts, without the deep conviction that it is an employment alike beneficial to the moral, political, and commercial interests of our fellow-citizens.”

In a letter from Commodore Downes to the Honorable John Reed, which forms part of the supplement to the report, that experienced officer observes—

“During the circumnavigation of the globe, in which I crossed the equator six times, and varied my course from 40 deg. North to 57 deg. South latitude, I have never found myself beyond the limits of our commercial marine. The accounts given of the dangers and losses to which our ships are exposed by the extension of our trade into seas but little known, so far, in my opinion from being exaggerated, would admit of being placed in bolder relief, and the protection of government employed in stronger terms. I speak from practical knowledge, having myself seen the dangers and painfully felt the want of the very kind of information which our commercial interests so much need, and which, I suppose, would be the object of such an expedition as is now under consideration before the committee of Congress to give.

“The commerce of our country has extended itself to remote parts of the world, is carried on around islands and reefs not laid down in the charts, among even groups of islands from ten to sixty in number, abounding in objects valuable in commerce, but of which nothing is known accurately; no not even the sketch of a harbor has been made, while of such as are inhabited our knowledge is still more imperfect.”

In reading this evidence (derived from the personal observation of a judicious and experienced commander) of the vast range of our commerce in the regions alluded to, and of the imminent risks and perils to which those engaged in it are subjected, it cannot but create a feeling of surprise, that a matter of such vital importance as the adoption of means for their relief, should so long have been held in abeyance. A tabular view of the discoveries of our whaling captains in the Pacific and Southern seas, which forms part of another document, seems still further to prove the inaccuracy and almost utter worthlessness of the charts of these waters, now in use.

Enlightened liberality is the truest economy. It would not be difficult to show, that even as a matter of pecuniary policy the efficient measures at length in progress to remedy the evils complained of by this portion of our civil marine, are wise and expedient. But let us take higher ground. They were called for—Firstly: as a matter of public justice. Mr. Reynolds, in his comprehensive and able letter to the chairman of the committee on Naval Affairs, dated 1828, which, with many other conclusive arguments and facts furnished by that gentleman, forms the main evidence on which the late committee founded their report—observes, with reference to the Pacific;

“To look after our merchant there—to offer him every possible facility—to open new channels for his enterprise, and to keep up a respectable naval force to protect him—is only paying a debt we owe to the commerce of the country: for millions have flowed into the treasury from this source, before one cent was expended for its protection.”
