Canals by Steam.—The Cincinnati Emporium informs us that at the woolen manufactory in that city there is a model of a machine for excavating the earth for the formation of canals, the invention of Mr. French, Practical engineer. It excavates, elevates, and places the earth on the side of the canal at any given distance from its margin at one operation. The great simplicity of its construction and movements, the almost certainty of its great practical utility, will render its invention at this particular period a matter of congratulation to the citizens of this country, and we trust of profit to its ingenious inventor. We understand a machine of sufficient magnitude is now building and expect this season to see steam successfully applied to digging canals.
