In the opinion of the writer, thor- ough preservative treatments would effect an ultimate saving ii] maintenance charges, a considerable part of the cost of application being offset by the use of cheaper grades of timber, which when treated properly will last longer than the highest grade of natural wood available. In very few lumberyards are the railway ties preserved in any way. In most cases they consist of inferior timber which readily decays. Many fruit bodies of dangerous fungi are usually present (PL III, fig. 2), so that it is important from the standpoint of sanitation to re- move this source of infection by the ap- plication of wood preservatives, such as creosote or zinc chlo- rid. A track in which the ties are creosoted is shown in figure 15. FOUNDATIONS. Probably no other factor involved in the storage of lumber in yards is open to more criticism from the sanitation stand- point than the foun- dations to the piles (figs. 16 and 34). Almost invariably these timbers are severely infected and often abundantly supplied with sporulating fruit bodies of serious wood-rotting fungi (PI. Ill, figs. 3 and 4). Various types of foundations are in use. The most primitive and most insanitary type consists in laying planks directly on the ground and stacking the lumber upon them. This procedure occurs at only a few of the smaller mills. A few of the mills make use of built-up plank foundations (PI. Ill, fig. 3), but the more usual method is to use 6 by 8 or 8 by 10 stringers, blocked up to a height of. Pig. 11.—A highly insanitary mill yard in South Carolina. Hundreds of thousands of feet of stored lumber have rotted in this yard as a result of these conditions. All this rotten debris should be removed and burned. 1.
