Abstract: Brashness, internal stresses, and hidden checks produced by poor drying may be passed undiscovered in the most rigid inspection, since they cannoit always be determined by direct examination of the material. The drying process itself is, therefore, of prime importance, not only for the saving of material through the avoidance of due waste from injuries, in drying but even more so for the assurance that the material which passes inspection shall be free from subtle defect or possible weakness. For this reason it has become necessary to draw up very careful specifications for the drying operations them selves, and to place inspectors at the kilns to see that the operations are conducted in accordance with the specifications. The need for this was realized when the airplane program was undertaken at the beginning of the war, and the Forest the safety of the drying conditionsas recommended in the specifications, but the second part has not yet been completely solved, and the experiments are still under way.
