The timber was piled in the open, and the section here shown was taken in 1906. It will be noted that the outer quarter of an inch of wood appears perfectly sound and that immediately inside this sound layer the wood has been completely decayed. There was absolutely no external sign on this timber which would indicate that it was not sound throughout. Instances of this kind are numerous and they naturally give rise to much ajjprehension on the part of the purchaser of timber, because it is not practicable to cut into timbers for the purpose of deter- mining whether they are sound on the inside. 149
