Agriculture; Agriculture. the kiln drying of the stock wherever possible and whenever the cost will permit; and in special cases steam treatment or the use of anti- septic dips, followed by proper piling to insure ample ventilation. It must be continu- ally borne in mind that none of these is by itself a sovereign remedy. Preservative dips or steam treat- ment were not in themselves, under the emergency manufac- turing conditions in- cident to the war, by any means sufficient to control molding of green stock when close piled in storage ware- houses or while in transit in box cars. In connection with this investigation, it should also be borne in mind that we are dealing with three distinct groups of fungi, namely, the molds, staining organisms, and true wood-destroying organisms, the antiseptics being more efficient against the last two groups than the first. As far as is known, neither molds nor staining fungi cause any ap- preciable diminution in the strength of timber and hence are Fig. 26.—Zigzag method of piling rim strips in box cars. unimportant in ve- hicle manufacture from the standpoint of strength and probably durability. The staining fungi can be controlled to a certain extent by the intelligent use of antiseptics and possibly by steaming, and it seems reasonable, in the light of experience, to suppose that the development of wood-destroying fungi can also be prevented.
