There are many methods of sawing logs to secure quartered-sawedor edge-grained stock. Some yield a greater per cent of lumber thanothers, although those which produce the greatest amount of truequartered material often yield the least total board foot contents,since true quartering is a wasteful process often causing the loss of 20per cent or more of the log content as compared to the yield fromplain-sawing. The choice of the method of quartering usually is based upon thepurpose for which the product is to be used. The chief reasons forquartering lumber are to show the figure in the wood; to secure a hardwearing surface which will not sliver; and to secure material whichwill hold its shape and be subject to minimum shrinkage and
