In the former case it is necessary to constructan inclined rollway over which the logs may be rolled into the LOADING AND UNLOADING CARS 333 water. This consists of a framework composed of three parallelsets of stringers, spaced 8 feet apart, which extend along thewaters edge for from 400 to 600 feet. The outer stringer projectsover the waters edge and is supported on piling or on timbersthat rest on solid bottom, while the other stringers are supportedon round or square uprights placed from 4 to 6 feet round or square timbers, often shod with railroad iron,are placed on top of and at right angles to the stringers, and serveas a bed over which the logs are rolled. These timbers arespaced from 4 to 6 feet apart on the stringers and have a pitchof from 15 to 2
