HEAVY 3ELENIULI DEMAND FOR RECTIFIERS FORESEEN FOR 1942
Metallic selenium of the absolute purity which is required in electric current rectifiers is now being refined in the United States in increasing commercial quantities to meet the requirements of the International Telephone & Radio Manufacturing Corporation for the manufacture of I. T. & T. Selenium Rectifiers. Early this year the Company doubled its Varick Street space, where the rectifiers had been manufactured. Last month it started prodution of the rectifiers in its East Newark, N. J. factory.
Oeorge Lewis, Vice President of I. T. & T. I>/Ianufacturing Corp, , estimates that his requirements of ultra-refined selenium may be 10,000 pounds monthly next year compared with only 1,500 poinds monthly at present.
As for the raw material supply, selenium is found chiefly in copper ore and years ago it was tossed on the slag piles. Inas¬ much as the United States and Canada together normally produce two or three times more copper than the rest of the world combined, Mr. Lewis says that selenium is one metal of which a shortage seems un¬ likely in spite of its rapidly growing importance in the electrical industry.

CALLS IT ’’NATION'S BULLETIN BOARD OF AGRICULTURE"
"Whenever this department wants to send out facts nation¬ wide we think first of the National Farm and Home Hour. It’ s one of the Old Reliable in our business of taking information to the American people. I know we’d be lost without it, and I think that millions of farm and city homes would be lost too. "
This is a quotation from a letter written by Secretary of Agriculture Claude R. Wickard, of Indiana, to Niles Trammell, Presi¬ dent of the National Broadcasting Company, in commera.tion of the 4,000th broadcast of the Farm and Home Hour.
Vice President Wallace, who also wrote Mr. Trammell, said:
"These broadcasts have done much to add to the knowledge and enjoyment of the people throughout the country, and I wish the National Farm and Home Hour many more years of usefulness. "
The story of the National Farm and Home Hour has made radio history. Back in 1923 when radio was in its swaddling clothes, a young man named Frank E. Mullen came out of South Dakota to take a job with the "National Stockman and Farmer" to direct farm broad¬ casts for them over KDKA in Pittsburgh, and he went ahead and organ¬ ized his programs.
