A few mills consider that such pre- liminary sorting is feasible from an eco- nomic standpoint, on account of the greater facility with which such stock can be billed out. From a pathological stand- point the practice is highly commendable. Uneven lengths allow rains to beat in, and also offer convenient and favorable lodging places for fungous spores. Likewise, marked disparities in length permit considerable warping of the ends, which often project out several feet from the main body of the pile. Figure 29 shows this condition in an exag- gerated form. To protect the ends of the lumber from beating rains as far as possible, the cross strips should be placed at least flush with the ends, both in front and behind. There still remains the question of roof- ing the piles. The commonly accepted pitch for lumber piles is 1 inch to the foot, and with a loose roof of lapped boards the greater part of the rainfall will drain away. The roofs must necessarily extend somewhat beyond the piles, in order to carry the drip clear of Pig. 2G.—Lumber piled in even lengths in a southern mill yard.
