Twenty-two shingle machines on one floor, Shull Lumber & Shingle Company's mill. General view of plant. Shull Lumber & Shingle Co., Ltd., North Arm of Fraser River. from such a large shingle plant. It is of heavy plate construction on a massive concrete foundation, and is lined throughout with fire brick. The steam installation is a battery of four very large boilers built by the Vulcan Iron Works, and the fire-box installation is of the dutch oven type in common use. Metal and concrete floors, and absence of wood in any portion of the structure near the fires is an aid to reducing fire risk. The conveyors are arranged to feed the fires automatically, and a supply of fuel can also be switched to storage space for hand firing when the mill is not running. Outside the boiler house two men remove the heavier portions of the fuel from the conveyors as it passes from the mill to the burner. This fuel is stored for further use in the hours when the mill is shut down. The engine room is equipped with two twin engines built by the Sumner Iron Works. They are each capable of generating over 200 and one can be shut down if one side of the mill is not operating, the two sides being run independently. For the genera- tion of electric light for the plant, a small engine is installed also, which operates the electric generating set. The power available is ample for the fullest load which the plant can put on it. The shingle machines are of the well-known Sumner Iron Works standard make, and according to the officials of the Shull Company, are giving entire satisfaction. Adjoining the sawing floor is a model filing room, where three expert filers find little spare time on their hands keeping the shining steel saws keen for the steady daily cut. While it is a daylight room, with light on three sides it is also supplied with numer
