Track Skate.—In regard to preventing engines from runninginto the pit, we have a very simple device which seems to haveanswered the purpose. It is a steel casting which we call a trackskate. It has a thin edge which l<es on top of the rail and theflange keeps it from shifting sideways, and the end is turned up6 or 8 so that in case the engine starts to move into the pit thetender wheel rides on this track skate and pushes it along and itacts as a very effective brake.—IVm. Elmer before the RailwayClub of OPERATING SHU cil ROD MILLING MACHINE. Forest Products Laboratory.—The governments new forestproducts laboratory will be located at the University of Wis-consin, at Madison. The establishment of this laboratorymeans the concentration of all lines of the experimentalutilization of timber and the checking of wood waste. ForestService laboratories for timber test work at Yale and PurdueUniversities and the governments wood pulp and wood chem-istry laboratory in Washington will be consolidated and trans-ferred to Madison as soon as practicable. A force of fifteen totwenty timber test engineers, experts in wood preservation, woodpulp manufacture and wood distillation will have charge of thework carried on. The laboratory will have an equipment valuedat not less than $15,000. The University will furnish the build-ing, light, heat, and power, and in return advanced students willhave the use of the laboratory for fpecial work in related lines. 162
