SAW MILL WASTE
How It Is Going to Be Utilized by an Alert Canadian
 Company.
WILL COME OUT AS PAPER
A Lot of It, Which Is Now Going to Be More or Less
 Valuable.


 Dudley, of Vancouver, states that un- usual interest is manifested in a new s1,O00,0OO company organized in that British Columbian city, owing to the fact that it will use the vast waste material from the saw and shingle mills, including the sawdust, which is now burned at some expense to pre- vent large accumulation The consul explains the plans and the proposed processes:
 This company first contemplated the establishment of it's plant at Aberdeen, Wash, but was forced to abandon that location, because it was found that the supply of fresh water was insufficient. After a thorough investigation it fin ally arranged for the purchase of so acres opposite Gambler Island, on Howe Sound, twenty miles from Van couver, at the entrance of Rainy riv- CT, where there is an abundant sup ply of water at all seasons.
 By utilizing the water power of the Rainy river the company will develop sufficient water power for mechanical and domestic use and for a series of mechanical grinders for the manufac- ture of ground wood, which is used to supplement chemical fibre in the man. ufacture of paper. The plan is to convey the refuse of the local mills of which there is said to be three thousand tons in this vicinity, in spe- cially prepared scows to the plant where the entire mass is to be disin- tegrated into suitable fneness for con- version into wood pulp. This will elim- mate the expense incident to the use of uniform cut wood, which is said to be the only method now in general use by the paper mills throughout East ern Canada and the United States.
 One of the innovations of the new company Is patented process where by 1t can use Douglas fir and other resinous woods in the manufacture of wood pulp. Papermakers in the past have never been able to use woods containing pitch and resin for paper purposes. owing to the difficulty in separating the cellulose from the pitch. resin and essential oils By the new process all those parts are pass cd off vapor and the fibre is recov- cred by subjecting the mass to a sys- tenn of pressing.
 The company now has in operation in Vancouver a complete but small plant for the manufacturing of pulp and paper, which fully demonstrates the process and which is both ingeni- ous and simple. The wood is first placed In what Is known as a chipping machine and reduced to small shay ings. The shavings pass up Hume and enter digester. which consists of a large perpendicular, copper lined circular reservoir that ordinarily ranges from to 12 feet in diameter and "A to 4S feet in height. The dl- gester is filled with a solution of caus- tic soda, and the entire mass of shaw ings, ranging from eight to ten tons, pressure of steam fo rseveral hours, until the cellulose is thoroughly re- leased.
 The mushy black mass is then re- moved to the draining floor or press where the caustic soda is separated as much as possible from the fibre. The material then passes to the beat ing machine, which consists of a wooden or metal tub ten CT fifteen feet long, with round ends, on the center of which is a partition called mid-feather. A roller is provided with knives and it revolves over bedplate of similar knives. The dis tance between the bedplate and the roller is regulated by wheel and screw The pulp, after 1t passes be- tween the bedplate and the roller, flows down the backfall and around the mid-feather back to the starting point. The machine is also provided with a washing cylinder, which is so made that as it revolves 1t scoops up the water, which flows through its axis; the pulp is kept out by a fine wire gauge surrounding the cylinder. 4 large quantity of water is admitted into the heater, which is removed by the drum washer. and the pulp is in this manner rapidly cleansed
 During the process of the beating this pulp is colored or bleached to any color desired. The bleaching is ac- complished by solution of chloride of lime. After passing through the beat ing engine the whole mass is run through a Jordan refining engine This machine consists of a stationary hollow comb, mounted with knives on the inside. which fit over a solid rap idly revolving comb mounted with similar knives on the outside. The pulp passes between the combs. and the knives can he brought close to- gether or separated with great ac- curacy, so that the degree of fineness i of the pulp can be adjusted. The material is then run into what is | known as pulp pit, where it is taken l mp by the large fourdrinier machines and run into merchantabe paper of different character and fineness.
 The plant. as outlined, will have capacity of 360 tons of finished ma terial week. consisting of 200 tons of news and 160 tons of manila wrapping box boards. building paper. etc In addition to the local trade. ] the company purposes entering the markets of Australia ana New Zea- land. Japan and the western United States.
