The accompanying illuslrations are reproduced from an articlein the Electrical Review, of London, descriptive of a single-railtramway invented by Charles Kwing, C. E., ot Adyar, system was the subject of a paper before the United ServiceInstitution of India by F. F. R. Uiirgess, who sairl in part: On a level road one pair of bullocks can, on a single line, drawa train of trucks, carrying a net load of from six to seven Ions, adistance of 15 miles in a day with case; it rcfjuircs from 16 lo 18. TRUCKS TO CARRY 3% TONS EACH. l)airs of bullocks to draw this load in ordinary carts carrying themilitary regulation 800 lb. load. The trucks run on a single line of rail laid on the ground orroadway and arc mounted on two or three double-flanged wheelsplaced under their center. These wheels arc of small diameter,varying from 15 to 30 in., according to the size and weight of thetrucks and rails, the flanges being twice as far apart as the widthof the rail on which the wheels run. The whole weight of the truck is thus borne on two or threedouble flanged wheels which run on the single rail, so that, unlessit were supported in some way, it must fall over. The necessarysupport is afforded by a lightly constructed iron balance wheelof comparatively large diameter, from 4 to 5 ft., with a 4-in. widetire, placed at the ;ide of the truck. This balance wheel runs on the surface of the-ground or road-way about 4^/2 or 5 ft. away from the rail. It runs on an axle
