The continual development of forest utilization and woodworking industries is reflected in the increasing demand for information on new equipment. FAO's Forestry Division, on the recommendation of the FAO Conference, collects such information and sends it on request to Member Governments. The Forestry Division would appreciate receiving data from manufacturers all over the world; specifications should be accompained by clear, sharp photographs (glossy prints). FAO, however, can accept no obligation to publish all such information received.
SPIRAL ROTOR TRENCHER. - This trencher, powered by a 6 h.p. gasoline engine, is designed to construct a fire line 18 to 24 in. in width. In operation, the spiral digs down to mineral soil and pushes the ground cover to either side. It is designed for working in deep soft soils, thickly matted grasses and medium brush types.
This is a pilot model weighing 550 lb. and under test conditions has been operated on slopes of 55 %, and on side slopes of 30%. Normal working limits up and down slopes are expected to be 40 %. Forward speeds ¼ m.p.h., 1 ¼ m.p.h. and 2½ m.p.h.; reverse speed - ½ m.p.h.

FORESTIERE C. D. 4. - This saw is easily transported, can be used anywhere and is simple in operation even for unskilled labor. It can be set up anywhere, requires about two hours to install and does not need any foundation or concrete work, it is simply placed on its rail track which has been carefully aligned and levelled. Since the machine is carried on guide rollers fitted with needle bearings the feed is flexible. The operator varies his feed speed according to the hardness of the wood, and, if he feels the slightest resistance slows down; adjustment of the thickness of timber cut is obtained by means of a small graduated wheel.
Specifications: Petrol, electric, or diesel motor as required. The petrol motor is of 2025 h.p., 4 cylinders; the electric motor averages 16-20 h.p. The saw pulleys are 1 m. in diameter, 90 mm. in width. The saw tension is obtained by means of a hydraulic appliance, the pressure being controlled with aid of a gauge; there is also a compensating spring. The Forestière C. D. 4 can use band saws up to 4 m. in width and can be used to cut logs up to 1.4 m. in diameter. The gauge between the rails is 1.50 m. and it is supplied with a track 6 m. long, which can, however be lengthened indefinitely so that several logs can be sawn one after another without stopping the machine. Average production is 1 to 2 cu. m. per hour for colonial timber, lineal speed of saw 22 m/sec. for hardwoods with a swayed tooth of 3a mm. pitch; 46 m/sec. for softwoods with a tooth spacing of 50 or 60 mm. The saw is fitted with a set of pulleys whereby the speed of the band saw wheels can be adjusted according to the species sawn.

PRECO BACK RIPPERS. - This fitting provides a new time-saving approach to earth moving for angling-blade bulldozers. Welded to the underside of the bulldozer frame, the rippers prepare the ground by ripping and scarifying when the bulldozer is backing up for the next forward blading operation; they float freely while blading is taking place. Teeth and shanks penetrate approximately 8 inches when hack ripping and can be retracted for carrying, back trowelling or smoothing. Housings are installed on the back of bulldozer mouldboards. Shank size is 3 X 4 X 26 in. Photo shows model R. A. 8 back rip scarifier mounted on Caterpillar D. 8 in action.
