Air-Drying and Pests.

“Coming to the point of salvage of non-heart timbers, it has to be borne in mind that the time taken by air-seasoning relative to kiln-drying not only means money, but means also greater risk to such timbers from exposure, because sapwoods are susceptible to the attack of pests while being air-seasoned. It is expected that kiln-drying will altogether overcome that difficulty, and will provide a sufficiency of the standard finished product, while reducing timber stocks and storage space required for air-seasoning, and will be both better and cheaper for the Department, besides assisting an important New Zealand industry.”
