THREE NEW MINES BUREAU SUBJECTS I TWO new motion picture films have recently been produced under the direction of the United States Bureau of Mines, in cooperation with industrial organizations, and are , ready for distribution for educational purposes in con- i nection with the mineral industry. The Story of Heavy Excavating Machinery, produced in co- operation with the Bucyrus Company, depicts in a vivid way the many types of steam, gasoline, and electric shovels and other heavy excavating apparatus that are used in mining operations. This picture shows scenes in the iron mines of northern Michigan and the quarries of New England, and illustrates coal stripping operations in Ohio, and also drag-line and tower work in the con- servation work along the Mississippi river. The second film, Mexico and Its Oil, produced in cooperation with the Sinclair Consolidated Oil Corporation, carries the audience from Tampico, Mexico, to the great oil fields of that country. While illustrating the technical operations of petroleum production, the film gives interesting insights into the domestic life of the Mexican people and affords many picturesque scenic views of that country. The film shows clearly the sequence of operations in the actual drilling and bringing in of an oil well. The United States Bureau of Mines has another picture owned by the Sinclair Company, for which they have obtained wide distribution. The film shows the importance of the oil industry and the story of its magic development in four reels ■ entitled The Story of Petroleum. The opening scenes show the geological survey, and when the location }{ the well has been decided upon, a. derrick is built, the drilling equip- uent is put in place, this is called by the workmen "rigging up." The drilling metliod shown in the picture is known as the rotary, the bit being lowered in the well bores through the various strata or layers of earth's crust, water reducing the residue into liquid form and forcing it out of the well. After the oil sands have been reached, the well is 'shot" unless it "comes in" as a large flowing well. The quantity of Jitro-gjfcerine used in shooting a well varies. The well "shot" in the film required ten shells, each holding twenty quarts of nitro-glycerine. When tlie well starts to flow, the oil is carried through pipes to temporary ield storage tanks. There are few geysers, contrary to general belief, jnd the oil is generally pumped to the surface. In 1919 there were 225,000 producing oil wells in the United States. The discovery of new oil fields makes rapid pipe laying a necessity, is temporary field tanks will not long serve to save the oil in a pro- iflc producing field. When it is necessary to clean the pipe-line, a ievice called the "Go Devil" is placed in the line. The "Go Devil" which s forced through the pipes by the oil scrapes them clean and pushes the •efuse ahead of it, travels from one pumping station to another. It is ocated in its course by a workman who by listening at the pipe is en- ibled to find the location of the "Go Devil" as it buzzes and whirls in its •nsh through the pipe-lines. On the most modern pipe line systems he pumps are run by internal combustion engines. The pumping station n the picture is the center of a system 2,800 miles in extent.

"FROM COCOON TO MILADY'S DRESS" -TlROM COCOON TO MILADY'S DRESS is a two reel picture X which shows the manufacturing process of silks and velvet* and their adaptability in designitig the fashionable costumes of today. The film contains many fashion drawings by Hy Mayer of beautiful women who fade into living models displaying the wonderful art of the costume designer. The source of supply of the silk industry is shown in close-ups of silk worms in Japan and the process of spinning and treating the raw silk so that it will be the high grade required for the American market. When the shipment of raw silk arrives at the looms it is soaked in water and dried by centrifugal machines. It is then ready for the intricate process of throwing, winding, reel- ing, which is depicted in the film. It is then ready for the looRis and the picture shows the manufacture of many materials in- cluding plush and velvet. Block printing, roller printing, and embossing on plush and tapestry are particularly interesting, as the camera has given close-ups of the methods used to produce these results. The picture was made by William Ganz and Hy Mayer for Sidney Blumenthal & Company, New York, who control the Shelton Looms, one of the largest plush and velvet manufacturing plants in the country.
