In the early days of the electric railway the return cir-cuit was neglected to a very great extent. At the presenttime, however, the necessity of making the return asefficient as possible is thoroughly appreciated, and nolittle ingenuity has been expended in developing bondsto connect the ends of the joints. There is no doubtthat the use of improved devices of this kind is the partof wisdom. With poorly connected joints the waste ofpower becomes a large item and the electrolytic evil isaggravated. We present descriptions and illustrations ofsome of the best known types of rail bonds: New Form of the Plastic Rail Bond. A new type of the plastic rail bond has been recentlydevised by Harold P. Brown, of New York, to meet the. PLASTIC BOND. growing demand for a method of rebonding old rails inpaved streets without disturbing the paving and to beproof against corrosion or hammering. Near the end ofeach rail a hole is bored through the lower lever of railsurface, into, but not through, the top of the angle drill has a point with a very obtuse angle, and as itpenetrates the lower surface of the rail it carries down aburr into the upper surface of the angle plate. Thisburr is partly cleared away as the hole progresses in depth,but a part of it is crowded back into the layer of rust be-tween the two steel surfaces, forming a telescope jointwhich is perfectly smooth on the inside. The drill is wetwith a solution of soda and water instead of oil, so as toprevent the trouble which follows the use of an insulat-ing fluid on a contact surface. The hole is amalgamatedby dropping in a piece of Edisons solid alloy andwetting the surfaces. This makes a laye~ of brilliantcolor which
