The edge piling of 2 by 4s (fig. 27),sticking the pieces in the usual way, has given good results at severalmills where flat piling produced an appreciable amount of deteriora-tion. The method of flat piling without the use of sticks, occasion-ally employed with 2 by 6s, in which horizontal circulation is pro-vided for by leaving wide spaces between the edges of the stock(fig. 28), would not appear to offer as good opportunities for dryinglumber in a moist climate as the more usual method which makes useof sticks. 26 BULLETIN 510, U. S. DEPARTMENT OE Besides the proper sticking and lateral spacing of lumber, a cen-tral flue one board wide running vertically through the middle ofthe pile is often of decided advantage. Many millmen recognizethis as good practice, but few of them consider they have sufficient yard space to carryout the method con-sistently. Another factorwhich enters into thestorage of lumber isthe piling of stock ineven or approximatelyuniform lengths (seefig. 26). A few millsconsider that such pre-liminary sorting isfeasible from • an eco-nomic standpoint, onaccount of the greaterfacility with whichsuch stock can bebilled out. From apathological stand-point the practice ishighly lengths allowrains to beat in, and also offer convenient and favorable lodgingplaces for fungous spores. Likewise, marked disparities in lengthpermit considerable warping of the ends, which often project outseveral feet from the main body of the pile. Figure 29 shows thiscondition in an exag-gerated form. Toprotect the
