Interest in the development of forest utilization and woodworking industries is reflected in the continual demand. for information on new equipment. FAO's Forestry Division collects such information and passes it, on request to Member Governments. Some of the information collected is published here. FAO accepts no responsibility for the claims put forward by manufacturers.

ALUMINIUM CHUTE. - Lightweight chute constructed under the direction of the Forestry Commission. Tests were carried out on an inaccessible site with 300 yds. of aluminium chute on a slope averaging 18°. 100 yds. of wooden chute on a slope of 28° fed timber into top of aluminium chute. Horse drag was used to assemble timber at top of chute. With aluminium chute dry, slope of 18° was not quite sufficient to keep logs running, but with the addition of a little water they ran well. Specifications: composed of 8 ft. long sections using 8 ft. x 2 ft. 6 in. sheets, 914 gauge; weight of one section, 24 lb. Sections are connected by pegs and sockets, so that no loose parts need be carried.
