Wood piles, used for foundation, ave subject to deterioration by various causes. One of the most severe is done by fungi. It is said that if wood piles are kept under the subterranean water, they do not go to decay at all, but if not, they will decay very rapidly. Then we made survey of nine examples on their decay. The following results were obtained. 1) The five wood piles were kept above the subterranean water among nine wood piles. 2) In some of the wood piles kept above the subterranean water fungi and termite damages were found. 3) In some of the wood piles kept under the subterranean water change of properties were found. 4) The deterioration of wood piles can be judged by moisture content.
