K.Fisher, in the last-named year; while abroad,from 1840 to 1875, several firms had succeeded in developing a business of considerable extentin the construction of road locomotives forhauling heavy loads, and in building steam roadrollers. A general idea of the machines built about this time may be obtained from the fol-lowing description of a road locomotive builtby Messrs. Avcling and Porter, of London:Weight of engine complete, 5 tons, 4^ cwt.(11,648 pounds!; diameter of steam cylinder,734 inches; stroke of piston, 10 inches; revolu-tion of crank to one of the driving wheels, 17;diameter of driving wheels, 60 inches; breadthof tire, 10 inches; weight of tires, 450 poundseach ; length of boiler shell, 30 inches; thicknessof shell, 7-16 of an inch; thickness of fire-box TRACITOX EXCxIXKS.
