great advances in engineering science since the days of Smeaton, and is made possible by the substitution of the screw propeller for the mule and tow-path. It is by this means that the Ohio River is to be made a great artery of commerce.[1] With steamers fitted out with low pressure engines it is estimated that freight can be transported profitably on the Ohio at an astonishingly low rate with which no land method of transportation can ever dare hope to compete. The new project of New York, therefore, brings back all the old-time dreams of early American promoters—of Washington's for the Potomac, of Morris's for the Mohawk, and of Robert Morris's for the Susquehanna. If modern engineering can make the canalization of one river a success, it can of hundreds of rivers. No sooner was the Erie Canal a success in 1825 than Ohio, Pennsylvania, Maryland and other states began canal building. No sooner had New York voted in favor of her thousand-ton barge canal than Ohio again followed by passing an act looking toward the improvement of her canal from
