Carroll F. Chatham, who is a San Francisco research chemist, has mastered the secret of growing gem crystals I Written up in Colliers, various newspapers and trade papers, Carroll Chatham came up with a real classic for display at the 16th annual convention of the California Federation of Mineralogical Societies in San Francisco's Civic Auditorium July B-10. A two-ounce, 300-CARAT emerald, no less ! The emerald had been developing in Chatham's secret research laboratory in San Francisco for over a year, and if the stone were the product of nature, its value would be in the hundreds, of thousands of dollars. As a man-made gem, its value is whatever Chatham puts on it. He is the only man in the world known to have cultivated emeralds successfully.

The emeralds Chatham grows for sale to the jewelry trade average one to five carats. They also take a year to mature, but Chatham gave the 300-carat stone "special cultivation" because it was to be an exhibition piece. He turns out some 5,000 carats of his cultivated emeralds a month. Except for a few stones that go to local lapiclaries, all are sold to a firm in Geneva, Switzerland.

Good natural emeralds bring $1,000 a carat and upwardmore than diamonds. Chatham sells his for about $100 a carat... and he's currently over $1,000,000 behind in orders.

Weyerhqeuser Tells Future of Foresf Products lo L.A. Rofory

John P. Weyerhaeuser, Jr., president of Weyerhaeuser Timber Co., told members of the Los Angeles Rotary club at a noon luncheon at the Statler hotel, July 8, that Pacific Coast lumber company foresters are working u'ith nature to hasten the slorv process of gro'w'ing trees to useful maturity and that, 'ivith modern practices and research, the lumber industry can guarantee an uninterrupted flow of wood products to meet all future needs.

Every detail in lumlter production and remanufacture was covered by Mr. Weyerhaeuser in his complete address (highlights of which will be printed in an early issue) and his appearance was rvell received by members of the Los Angeles service club.

L. A. Lumbermen in Audience

NIany Southern California lumllermen, Hoo-Hoo and building material merchants were in the audience to hear I I the noted speaker. Included u,ere Bob Osgood, LeRoy H. Stanton, Sr., John Osgood, Jim Forgie, Les Lynch, Frode Kilstofte, George Fredrickson, John Lipani, Bert McKee, Ken Tinkler and Milan Michie.

California and Oregon norv lead the nation in lumber production, Weyerhaeuser said, and \\rashington is the top rvood pulp producer. Plywood, in 5O years, has become a regional phenomenon and does an annual $500 million business.

"I assure you that the nation is not running out of timber," the speaker stated. "Despite the gloomy predictions of some alarmists, our country is growing each year an amount of timber equal to that which is being harvested.

". . For the most part, our industry is deeply conscious of its stervardship," Weyerhaeuser continued. "Timber is renewable and rvith diligent research and intelligent management, its harvest tvill never end."
