XvUMBERIvIJLlSI June, 1899 THE DEVELOPMENT OF WOOD-WORKING MACHINERY.* By Iohn Richards. As has been explained, forest sawing, or green sawing, as it is sometimes called, is in Europe a less important process in timber-coverting than it is in the United States. Log sawing is carried no further than the reduction of timber to merchantable shape by removing the surplus wood and waste, so that the balks and deals will be in suitable form for transportation and for re-sawing at the timber yards, where they are reduced to finished dimen- sions as wanted. This is, in several respects, a rational way of proceed- ing, which will, no doubt, be introduced into the Ameri-. Fig. 1.—The First Band-Saw Machine. (Patented by William Newberry in 1808.)

The advantages are that the timber is not injured in transportation by breakage or exposure, and can be handled at half the cost when proper tackle is employed ; there are no grit, dust, and season cracking to contend with, and the re- sawn timber can be furnished to customers bright and clean, and with accurate dimensions. Deals, which seems to be a name for any kind of squared pieces whose section is a parallelogram, form a unit from which two- thirds of common lists can be cut out with but little waste, as is proved by the small amount of debris found about saw mills in European cities. It is commonly assumed that any sharp wood-cutting implement driven by steam power will displace enough shavings or sawdust to supply fuel for the power con- sumed, but this depends in a great measure upon circum- stances.
