Instances are common wherein small amounts ofpower are required for outlying points which cannot befurnished by the constant current system because of thegreat distance from the central power plant. In casesof this kind this combination system would meet therequirements by supplying the outlying points withalternating current. O.

Drop Testing Machine HE Master Car Builders droptesting machine, which has forsome time been in process of erection,is now completed and ready for direction of the association, this ma-chine has been installed at the labora-tory of Purdue University, Lafayette,Indiana, where it will be operated underconditions similar to those prevailingin connection with the Master CarBuilders brake shoe testing machineand the Master Car Builders air braketesting rack. The conditions are suchthat the machine may be used not onlyby committees of the Master Car Build-ers Assocation, but also by individualrailway companies and manufacturersas well. The machine has been described indetail in the proceedings of the Associa-tion for 1903. The drop weighs 1,650pounds and is so designed that supple-mental
