LAKE SUPERIOR.—The investigation made at Keweena Point by Mr. Schoolcraft and doctor Houghton on their late expedition to the sources of the Mississippi, though only superficial, warrant inferences that copper ore will be found there in such abundance as to invite and reward future exertions. The mineral associations are there all of a promising character, and the specimens brought back are rich in variety and beauty. The determination of such an important fact is highly to be estimated. It may have a marked influence on the coming prosperity of lake Superior. It is known that arrangements are now in progress by the great fur company of the north west, to extend its establishments at La Pointe so as greatly to enlarge the business of those waters; much of that which has been heretofore transacted on the lower lake, at Mackinac, will hereafter be done at that more remote place. A schooner will be constructed at the Sault St. Marie this winter, to be launched the ensuing season. Such a craft will at once open new facilities for the advancement of science as well as commerce, and we may anticipate that lake Superior will in the course of a few years more be nearly or quite as well known as its sister lakes below; and that its mineral wealth, its picturesque and often sublime scenery, will have other witnesses and admirers than the rare few who have the enterprise of Mr. Schoolcraft and his associates.—Detroit Journal.
