It began in the early 1920's with a one-man seasoning department designed to give seasoning consultation to member mills. Today its laboratory facilities and 11-man stafi direct their energies to the exploration of the'rvorld of wood and its further possibilities in utilization, preservation and beauty.

Among the developments in which the laboratory played a large role are the knot sealers (WP-578 and WP-578-P) and Permatol (pentachlorophenol) wood preservative.

The knot sealers have helped in attaining higher utllization for knotty grades of lumber, doing so by providing a method whereby knots may be sealed to prevent their resins from bleeding through the paint. The early, clear sealer stimulated the use of economy (knotty) siding and other knotty lumber with pairlted surfaces. Last year, the pigmented sealer was released for manufacture, and in a sense has "put more economy in economy siding" by combining the sealing and primer-coat applications into one step.

Permatol, second only to creosote in use in this country as a wood preserver, helped the woodwork in-
