The writer believes that a greater quantity of manufactured lumber can be got out of a small lofir more cheanly with a stock gang than it is. The sawdust screen which separates bark splinters and chunks from the sawdust, ensuring a regular supply of clean fuel to the Dutch ovens. possible to obtain with a band and resaw. The saving affected in securing the same output over the old mill was 135 men and 12 teams. This, I believe, could be much furthef increased if it had been the case of laying down a new plant rather than the re-design of an old one. Installation of Vertical Band Resaw Among the alterations and ad- ditions which have recently been made is the Waterous-Johnson vertical band resaw. This is an equipment which has just been put on the market and is a great labor and material saver. The machine is the result of the com- bined study and experiments of the Waterous Engine Works Co. of Brantford, and Col. George H. Johnson, chief engineer of Mc- Lachlin Bros., of Arnprior, and late commander of the Forestry Battalion in the Jura Alps, France. The vertical band resaw will, the makers state, positively cut straight boards from slabs and half logs, regardless of irregu- larities in the material. It is further contended that the new vertical band resaw combines all the good features of the horizontal band resaw with that of the vertical. The machine consists of a complete, standard W
