This valuable body of water, which bounds the northern part of Ohio, is rapidly becoming the vehicle of an extensive commerce. A few years ago only one steam boat navigated this lake, and that one with little encouragement; now six regularly ply between the border villages on its shore, and points on the western lakes. Nearly one hundred coasting vessels now whiten the lake with their sails, conveying the rich products of western argriculture [sic], to New-York or Montreal. The number of vessels will increase in a great ratio every year, as the borders of Lake St. Clair, Huron, Michigan and Superior, invite the attention of enterprising emigrants. When these become settled, Erie, one of the links af [sic] that extensive chain of lakes, will be the medium of conveying the products of the "upper country" to one of the great commercial outlets.--The Ohio Canal, when finished, will also add greatly to the commerce of the lake. A Spectator, a century from this, may realize the fables of the poets, in seeing "a living forest of masts." Congress have not been unmindful of the commercial advantages of Lake Erie. Several light houses have been built, on the borders, and considerable appropriations have been made for the improvement of the harbors at the mouth of G. River, Cleaveland, Presqe Isle, &c. It is gratifying, for an American, to see the provident care, which Congress exercise[s] in promoting the different interests of the union. The promoting of these interests to avoid the charge of partiality, requires a steady and prudent course of policy. The west is growing in importance--her weight is sensibly felt in the general government; and she may now expect that an equal attention will be paid to her wants, as to those of any other portion of the union.--Ohio State Jour.
