The best criterion, therefore, as to the comparative efficiency of one device over mother would naturally be in the larger number of machines in use to- jether with the duplications of these machines. If this assumption is â orrect there can be no question, but what the McGiffert log loader takes _ foremost place among loading devices. Anyone who has traversed the imber sections of North America and seen the large number of these /lachines operating successfully, under all conditions, and handling all inds of timber, will admit this to be the case. To appreciate more clearly the manifold advantages possessed by tais machine, a brief enumeration of the requisites necessary for a suc- cessful log loading device together with a short description of the Mc- Giffert design, and its method of operating will be of assistance. In the first place to load logs most economically on cars the loading device must be self-propelling, able to move itself or its cars to any point and at any time. It must al
