Dickinson Tqlk Opens SCUiA Yecr

The first meeting of the Southern California Lumber Seasoning Assoiiation of the fall year was held October 4 after a fine meal of prime rib at Curries Santa Fe, Long Beach. The meeting was called to order by President Herb Geisenheyner at 8:15 p.m. He immediately introduced the guest speaker of the evening, Dr. Fred Dickinson, director, Forest Products Laboratory, University of California, Richmond.

Dr. Dickinson's talk was "The Effect of Time, Temperature and Relative Humidity on the Relief of Case-hardening Stresses.f' The talk included slides which illustrated the results of this study. It rvas most interesting to learn what efiect high heat will have in the relief of drying stresses. It can also be assumed that a combination of high heat plus the usual high humidity is even more effective in relieving these stresses. A lively discussion followed this talk.

Announcements were made that a Kiln-Drying Course will be held at the Oregon Forest Products Laboratory, Corvallis, December 3, and the same course will be held at the California Forest Products Laboratory, Richmond, l)ecember 10.

The next association meeting will be December 6 in the Los Angeles area and announcements will be forthcoming as soon as arrangements have been completed.

Those attending October 4 were: Jack Johnson, Cort Mason, Downey Dry Kiln and Milling Co.; Harland Walters, Penberthy Lumber Co.; Earl Simon, Hammond Lumber Co.; Frank Keuski, Associated Molding Co'; Charles
