Thismethod has proved entirely satisfactory. In laying sticks careful attention should be paid to placing thesuccessive strips vertically one above the other. If they are placedhit or miss, certain ones may fall in the span of the next tier below,thus producing much unnecessary warping of the lumber, due tothe pressure of the overlying layers. In all cases of flat piling of green lumber care should be taken toleave a space of at least half an inch between the edges of the gives a vertical air circulation, which is particularly P88F Fig. 25.—Piling sticks placed on wet ground beneath the skids. In order to keep themfree from infection, such sticks should never be placed in contact with the soil. Two other methods of piling 2 to 3 inch stock are used to someextent with good results. 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.
