So far as I am aware, the only attempts to solve this problem which have heretofore met with any measure of success, have been made in connection with a certain class. of vessels, the machinery of which was governed by electric currents conveyed to the controlling apparatus through a flexible conductor. But this system is subject to such obvious limitations as are imposed by the length, weight and strength of the conductor which can be practically used, by the difficulty of maintaining with safety a high speed of the vessel or changing the direction of (1) 225
