To pay 5 per cent, on the capitalthere will be required, after recouping ,the sum of $135,000 per annum to be raised byfares of 4 cents for any distance. A part of theroute traversed by the subway is alreadycovered with a system of tram lines, and fromtheir published accounts we find that theaverage annual earnings per mile are about$70,000. Consequently if the subway is nomore successful than its competitors overheadit will take $232,500 per annum. One need notbe very sanguine, however, to believe that theunderground traffic will greatly exceed thatof the tramways. Safety Device for Overhead ElectricConductors. * The danger of dangling electric conductors,charged with high pressure currents, has beendemonstrated so often and so seriously, that anypractical invention relieving overhead conduc-tors of their deadly menace to life should beheartily welcomed by both the
