President Ray Benson turned the me_eting.over tosecretary-Treasurer Bob Inglis of Associated Molding Co., Los Angeles, to lead the gen&al discussion on future plans of the association. All members present took part in the lively talks preliminary to action at the general election meeting in June.

The discussion centered around whether to keep the meetings small for kiln operators and technicians -only, or make the activities larger for all-industry participation with some non-technical meetings to be programmed.-

- Inglis also reviewed the photo slides he had had made up into a story feature for the annual conference of the West-

After dinner the meeting was called to order by the president, Ray Benson.

Dr. Robert Cockrell, professor of the School of Forestry at the Universitv of California. Berkeley. was introduced. His subject *"i "Stt.t.tural and Physiial Characteristics of Wood As Related to IJse."

"Out of over 800 soecies of U.S. trees. about 100 are used commercially but leJs than half of theie are employed directly in any quantity by the woodworking industries. To these, however, must be added a goodly number of exotics such as the mahoganies and many hardwoods; hence it is essential that manufacturers be familiar with kinds of woods in conducting their operations. Unlike man-made materials with relatively uniform properties, such as metals and ceramics, wood is a 4atural product with considerable variability, put together by trees to serve their particular purposes. In making use of wood, therefore, it is all the more necessary to understand well all of its properties and something of its natural variability so that difficulties in fabrication and performance will be minimized," the speaker said.

Dr. Cockrell used many slides to illustrate his very informative and interesting talk.

The remanufacturing and drying facilities of the Ralph L. Smith Lumber Company were inspected by members of the Central California Dry Kiln Club at their Tanuary 15 meeting. Of particular inteiest were the Laucks riroisture sentry operating on the dry chain and the extent of edge and end gluing used in remanufacturing operations to upgrade final products and to reduce residue. Luncheon was hosted by the Ralph L. Smith Lumber Company at Buzz Dyer's.

The business meeting was called to order by President Flavel D. Grubb at l:45 p.m. and staff members of the host company were introduced. President Grubb thanked the company for the luncheon and for the Anderson plant tour.

The annual Western Dry Kiln Clubs meeting was to be held at the Hotel Florence, Missoula, Mont., June 23 and 24, and it was proposed that the CCDKC present a paper on moisture content of dried lumber with particular reference to white fir, as detected by the Laucks moisture sentry, at that time. Harvey Smith and John Dittman (Winton Lumber Company) were to author the presentation. Mr. Smith outlined the project to the meeting and requested the assistance of those companies that are using Laucks sentires to carry out specific tests at their own plants in order that this material could be included with the Winton Lumber Company study. Plans were made to put the extended study into effect.

For the technical session, President Grubb introduced Ed Knight of the Western Pine Association, whose topic was "Brown Stairl Control in Sugar Pine." He reported that studies on brown stain in sugar pine commenced some 20 years ago when a group of kiln men met and considered means to overcome the problem. Several years later, Carl Rasmussen found that the period of log storage was an important factor causing stain. Dr. Stout subsequently found in a study at Collins Pine (Chester, California) that the time boards are held between sawing and drying was of more importance. Even a holding period of two days was sufficient to cause substantial stain. Dr. Stutz, in a study on mill-run material on all types of logs at Woodleaf, showed that logs opened to the air in the woods or storage caused stain irrespective of subsequent care in handling.

Other points of interest mentiontd by Mr. Knight were that yard-dried lumber (not dipped) did not appear to stain as badly as kiln-dried lumber. Also, in at least one for control of stain, there have been some instances of ill effects on workers, par,ticularly headaches; but these have been in enclosed situations where ventilation is poor. Some workers are also sensitive to pentachlorophenol, but no serious problems appear to have yet arisen with respect to toxicity.

In the discussion period which followed, several members indicated that dip trqatments were successful in their operations and that drying times were being reduced as schedules were stiffened up.

Claude Parker, plant superintendent of Ralph L. Smitl-r Lumber Company, said that ill effects to operators was causing them concern. Particular people affected were those on the green chain, and, at one stage, twelve men had had medical attention. Plant safety inspectors were, in general, suspicious of the process and tended to back operators' complaints. A very real problem exists, in his opinion, and prevents universal adoption of the process.

There was some discussion on preventative measures, which included adequate ventilation and supply of waterproof protective aprons, trousers, and gloves for workers. It was pointed out that, in hot climates, men would not or could not wear protective clothing.

President Grubb thanked Mr. Knight for a very informative presentation and the meeting adjourned at 3:37 p.m.
