FORESTS FORESTS 337 wheels one to several logs are suspended, the rear end being allowed to drag. Roads.—Fairly good roads are made through the woods for a single crop, because a large number of heavy loads must be hauled over some of them. Swampers cut out the underbrush and clear away obstructions, after which grading is done if necessary. Miscellaneous means.—In some mountain- ous regions, where rocks do not interfere, timber is allowed to slide down the incline on the bare ground. In the extreme West and Northwest, huge logs are dragged on the ground, rollers being supplied to con- vert sliding-friction into rolling - friction. Cattle, a means of power which has been largely used in harvesting crops, are used for this purpose because of their strength and convenience. In the South, what is called "drumming" is employed to a limited extent. This appliance consists of a large cylinder made to revolve, and which winds up a rope or cable, the outer end of which is fastened to the log. A much more pow- erful and practical method is the steam skidder, which, by means of pulleys and a cable, gathers the logs from a few thousand feet on either side of the track on which it moves and places them on the cars, if need be. Temporary tracks of either narrow or standard gauge are laid into the woods and camps, and when the timber in one place has been harvested they are taken up and relaid in an- other place. These are contrivances for short hauls to get the logs to the steam railway, on which they are placed and transported longer dis- tances to the mill. A great deal of lumber is now kiln-dried either after air-drying for a time or fresh from the saw, thereby making it fit for use much sooner than by air-drying alone. When the lumber is finally ready for the wholesale or retail dealer, it is again trans- ported to the most
