. Canadian forest industries 1897-1899. Lumbering; Forests and forestry; Forest products; Wood-pulp industry; Wood-using industries. Fig. 2.—View of Jack Ladder, Mill. each carrying 60 inch Hoe inserted tooth saws. The carriage for this rig is of the well known Pacific coast type, with screw headblocks, having knees receding 60 inches from the saws, and is capable of taking a log five to six feet in dia- meter and eighty to ninety feet long. The set works on this carriage is operated by power and is quick and accurate in its action, setting to within a small fraction of an inch. The logs are handled to this carriage by means of two heavy straight line steam canters, each having one vertical and one horizontal cylinder. After the logs are cut up into the dimensions required, they pass on a line of live rollers which extend to tho end of the mill, and long pieces are cut to the desired lengths by steam jump-up saws, of which two are set in between the rollers. If the logs are cut into cants, they are carried across the mill by means ot transfer chains to be cut up by an improved Prescott No. 3 band saw mill, having wheels 8 feet in diameter. The carriage on this side has knees receding 54 inches from the saw, and will take logs or cants 40 to 50 feet long. Logs can also be taken on this side from the log deck, and both can^s and logs are turned by one heavy steam canter of the same size and kind as that on the circular side. The feeds of both carriages are the well known Cunningham patent twin engine steam feeds, with drums grooved for wire rope, the one on the circular side having cylinders 14 inches in dia- meter, and that on the band mill side having cylinders 12 inches in diameter. On this side likewise there is a complete line of live rollers to the end of the mill to carry finished stock out. Should any boards or plank require to be edged from either side, they are transferred to the J Terms,$ Per Year. i Single Copies, 10 Cents. edger by means of c
