The pulp table E F is situated con- vi nient for loading and carries the scales in its centre. The size of the bale, if standard 72-inch wet machines are used, will be 24 inches long by 18 inches wide, while the height will vary according to the amount of pressing, generally about 12 inches to 14 inches. Its weight is 200 pounds if the pulp shows 50 per cent, in the moisture test. Wrappers.—Owing to the loss by abrasion and dirt that is always met with when pulp is shipped without a covering of some sort on the bundles, there have been many attempts made by different manufacturers of pulp to produce a serviceable and cheap wrapper. These efforts have been made with various degrees of success, using many different materials. The best form of wrap- per yet introduced is a cloth bagging of either jute or calico. In some mills where this wrapper was tried, it was given up on account of its expense. Wrappers are made in some mills of pulp. The wood used is the usual spruce, such as is used in making the ordinary grade of pulp, but after being sawn and barked, it is steamed in a steamer, under a pressure of 60 to 75 pounds per sq. in., until the wood is practically cooked. This steaming loosens up the fibres of the wood, which, when ground, produces a dark colored pulp with a longer fibre than is obtained from the raw wood. It is cut from the wet ma- chine by a pin to secure a smooth edge, as the knife fends to crinkle the sheet. The wrappers are cut from the sheets and afterwards air dried. Two are placed on the bundle, one below and the other above, while their edges overlap. No covering is provided for the ends of the bundles when they are wrapped in this way. If more att
