If it is imperative to get protection against moisture swelling the wood, it would probably be better to run a few grooves in the back, like some planing mills do in window and door frames. Take in- side casing for doors and windows, for exampe. When it is hollow-backed one has only the edges for a chance to nail through and get a bearing; then if moisture gets into it, it will cup anyway. It looks like it would be safer and better to protect the back against swelling by cutting a few grooves in it with the saw, lengthwise the stock. Or, why Dot follow the best plan yet, and see that the plaster is thoroughly dry be- fore putting it up, then dress the back smooth and straight? Maybe, some day, we will get to this. Meantime, there are Two points that need consideration: First, is hollow-backing a habit or a necessity ? Second, if hollow-backing is a necessity, doesn't it need reforming and refining? Satisfactory Method of Quarter Sawing A method of quarter sawing oak which is employed by one large operator with considerable success is illustrated by the cut appearing herewith, showing the log marked for quarter sawing. The distinct medullary rays in the oak extend in vertical plates from the centre of the tree toward the bark, and the method of sawing indicated, running. HEAD Illustrating Methods of Plain and Quarter Sawing closer to the grain line than the ordinary process of quarter sawing, seems to bring out a little better figure and produce a better quality of quarter sawed lumber. The other illustration shows a satisfactory method of plain, sawing oak to get the best possible amount of good lumber out of the — American Lumberman.
