This valuable traffic, which is at once the instrument of exploration and the nursery of seamen, was by the convention of 1818 suffered to be pursued promiscuously by British and Americans, and in consequence of that suicidal provision is fast being diverted from the latter to the former. Our exports of furs to Canton amounted in 1821, to $480,000; in 1832, to about $200,000, and in 1839, to $56,000, showing a gradual decrease between the years 1821 and 1839 of more than seven-eighths, in the amount and value of this trade. A better practical commentary is not needed upon the effect of our legislation, and while Americans are thus annually withdrawing from this trade, Great Britain is extending her facilities for commanding it every day. Her hunters and trappers are scattered over the whole extent of the territory; nor are they content with the legitimate profits of the business. While within the British Territory the strictest provisions are made to prevent the destruction of game unnecessarily, no such precautions are enforced here, but on the contrary the Indians and others are encouraged to hunt at all seasons of the year without regard to the preservation of game. The result of this will be the extermination of the beaver and other animals killed for their fur within a few years unless the United States interferes. [From the _Tribune_ (New York), December 14, 1842.] THE NORTHWEST COAST. Some apprehension exists that a settled design is entertained by Great Britain of disputing our claim to the territory beyond the Rocky Mountains and the whole Pacific Coast in that quarter. A letter to the editor of the _Globe_ from an officer of the United States ship Dale, belonging to the Pacific Squadron, dated “Bay of Panama, September 23, 1842,” contains the following paragraph: We sailed from Callao seventh instant in company with the frigate United States (Commodore Jones’ flagship), and sloop-of-war Cyane, but we separated from them and bore up for this port on the seventh day out. Just previously to our departure two British ships-of-war (the razee Dublin, and sloop-of-war Champion) sailed thence on _secret service_! Of course this mysterious movement of Admiral Thomas elicited a thousand conjectures as to his destination, the most probable of which seemed to be that he was bound for the Northwest Coast of Mexico, where, it is surmised, a _British station_ is to be located in accordance with a secret convention between the Mexican and English governments! And it is among the _on dits_ in the squadron that the frigate, the Cyane, and the Dale, are to rendezvous as soon as practicable at Monterey to keep an eye upon John Bull’s movements in that quarter.
