The paper describes the electric logging engines installed in a timber district in Idaho, and gives the results of tests of these machines. The carrier system is known as the "skyline" system, which is especially adapted to steep hillsides, and as the logs are carried with only one end trailing on the ground, rock and gravel do not become embedded in the bark, thus avoiding disastrous results to the saws in the mill. The estimated saving of the electric over steam operation for this installation is at least 50 cents per 1000 log-feet, and the electric drive also embraces many collateral advantages which are enumerated.
