Charges that John L. Lewis 'saw to' the discharge of men to coerce workers. Washington, D.C., Dec. 13. Joe Ozanic, International President of the Progressive Mine Workers of America, testified before the Smith Committee investigating the National Labor Relations Board. He charged that John L. Lewis, as President of the United Mine Workers of America, caused the discharge of five men in the Progressive Union, to 'bring pressure' on other employees to leave the Progressive and join the United. 'The United Mine Workers--and if I've got to use the name of the dictator, John Lewis himself--brought pressure on the employees to force them to sign a petition. They refused. He then saw to it that the coal company discharged five men. The others then did sign the petition resigning from the Progressive Union and pledging loyalty to the United. They did it to save their jobs,' he told the committee

Bureau of Standards puts ruge insulator through pressure tests. Washington, D.C., Nov. 30. H.L. Whitemore, (left), chief of the Engineering Mechanics section, National Bureau of Standards, and Dr. A.H. Stand, make a final check of the huge 1600[?] pound porcelain insulator before subjecting it to 2,180,000 pounds pressure in the Bureau's hydraulic jack. The insulator, one of the few of its size in existence, will serve as a base for a 640 foot mast at Radio Station WGY, Schenectady, New York. One of the insulators successfully stood the pressure to 800,000 pounds while the second broke when the pressure was boosted to 2,180,000 pounds. The hydraulic jack is capable of exerting 10,000,000 pounds pressure

Ancient brain surgery. Miss Helen Hecker, secretary to Dr. [...] Curator of Physical Anthropology of the Smithsonian Institution, poses with an ancient trephined skull discovered in Alaska by Dr. Hrdlicka, which is believed to prove that brain surgery was practiced there as long ago as 2,000 years. Dr. Hrdlicka made his discoveries from the lower strata of an ancient settlement on Kodiak Island. He believes that trephining among the Indians was a practical surgical operation, designed to relieve pressure against the brain from a skull fracture, and to remove bone splinters. It also is believed possible that these holes were bored in skulls, at times, to let out evil spirits causing headaches, 11/23/35
