Demonstrates non-sinkable ship to members of Congress. Adam T. Drekolias, of New York, demonstrating to members of the House Naval Affairs Committee, February 24th, his invention which he claims will keep any ship from sinking, no matter how badly damaged. The invention is a collapsible chamber designed to ? air in the hull of a disabled vessel, even if a ship were completely filled with water. He claims the device would keep its upper deck above the surface, giving the crew a chance for their lives until rescuers arrived. Mr. Drekolias is shown on the left in the photograph

Uncle Sam spending $3,000,000 to make one map. Washington D.C. July 28. A huge photographic map which when completed will have cost $3,000,000, is being put together by the Agriculture Adjustment Administration, Department of Agriculture, in Washington. Approximately one-thrid of the entire land surface of the United States is being photographed from the air from a distance of three to five miles up. The idea behind this gigantic job is to determine compliance in the Agricultural Conservation Program, plan soil conservation or Public Works projects, lay out roads, forests and public parks, drainage ditches, dams and lakes and also to seek to improve National Defense.

West Mine, West Frankfort, Illinois. Now abandoned. This mine has been down about a year. General caption: Many of the miners displaced by machinery in the larger mines are left stranded after mines are abandoned; have opened shallow primitive workings on the coal seam where it occurs close to the surface. The output of these shallow mines, known locally as gopher holes, is processed by a crude method and sold to truckers at about half the price of deep-vein coal. Many of the gopher holes have no storage in the tipple, and the miners underground are idle when no truck is waiting at the chute to load coal. Wages of gopher hole miners run from seventy-five cents to five dollars per day, and many miners earn less than WPA (Works Progress Administration) workers. Some of the larger gopher holes, such as Blue Ribbon Number 2 at Spillertown, Williamson County, are better equipped, pay better wages, and produce as high as 40,000 tons a year

Conversion. Copper and brass processing. Drawing seamless copper tube. Rough cast tubes tapered at one end to fit through a die are gripped in the tongs of the electric motor-driven vehicle on the drawbench and pulled or "drawn" through the die to reduce them to the desired size. Tubes usually are redrawn many times; each successive "draw" reduces the diameter, and increases the length. Brass tubes need to be annealed or softened between each draw, but copper tubes can be drawn several times without intermediate annealing. The tapered nose of the tubes may be seen just behind the drawbench operator. The tube is checked with a micrometer after being drawn, to make sure it is the right diameter. The man looking through the short section of tube is inspecting the inner surface for flaws. The Chase Copper and Brass Company, Euclid, Ohio
