No defects, such as checking, etc., were occasioned by the kiln drying, the only variation from the normal experienced being that the timber, as shown by a pronged section, was slightly case-hardened. The prongs, turning in as they did, indicated that the outer core of the timber had dried more rapidly thai! the inside and become set, The.
