We have not within reach the number of miles of river navigation, except by the tedious process of adding the navigable waters of all the rivers and streams of the world. It may be said, however, that the corps of United States civil engineers has estimated that there are 20,000 miles of navigable waters, or waters that can easily be rendered navigable, in the Mississippi system, and in the St. Lawrence system there are about 15,000 miles more, under the control of the United States alone and with Canada.
