Educational films [Continued from page 379] reassuring of the complete possibilities of success in such a venture. ■ Making 16mm. records of eye cases under treatment, League member R. M. Peckham, optometrist of Rochester, N. Y., reports some very helpful and interesting studies have been completed. One film, that of the progress of a crosseyed patient, has been used with considerable benefit for lay showings. Another, a film story of a nearly blind child whose sight is being restored without an operation, has attracted considerable attention. At present, Dr. Peckham is interested in the use of animation to record certain aspects on care of the eyes. He believes 16mm. film offers a splendid medium to convey to the public the work specialists are doing in many different fields of health. Industrial ■ Comparing the swivel butt coupler, a new type, with the standard, rigid shank coupler, 16mm. films, produced by League member H. G. Swan, engineer of tests for the Symington Company, New York City, permit railway officials virtually to ride between the cars and see exactly how these different types of couplers behave under various conditions of strain. This ability to bring to view and permit evaluation by comparison of points of competitive products not otherwise easily demonstrated constitutes one of the many applications of 16mm. film in sales programs. The illustrations, below, enlarged from 16mm. frames, show, Scene 1, how a standard rigid shank coupler pulls through the nose when going around a Enlarged frames from a 16mm. industrial showing coupler performance curve and how such couplers turn separately, causing slippage and surface wear; Scene 2 shows how, in the Symington coupler, the pull is squarely on the full faces and that the coupler pair forms a single radial member between the cars; Scene 3 illustrates the Symington coupler pulling around a curve: Scene 4 shows this coupler holding back on a curve. ■ Woolen Manufacture, 1200 feet 16mm., tracing clearly for the layman all steps in this process from picking and sorting of wool through washing, carding and spinning to final weaving, has been produced at the New Jersey Worsted Mills, Inc., Passaic, N. J., by Richard Dawnay, League member. That fundamental processes of wool manufacture have remained unchanged through the ages while only the technique and machinery have altered is pointed out in this comprehensive subject by titles which are both full and concise. The film was not made for advertising purposes but as a complete recording of modern woolen manufacturing processes. B Featuring the use of organic colloids in scientific methods of water correction, a 600 ft., 16mm. film is now in production by League member L. I). Betz, chemical engineer of Philadelphia, Pa. The film will show how soft water in the course of its history dissolves mineral salts and becomes hard and how industrial use of this water does damage. Methods of softening water will also be presented in detail. It is to be shown before engineering societies preceding experiments demonstrating the use of organic colloids. School I The importance of visual methods in teaching, particularly use of the talking film, was stressed at the recent annual convention of the Childhood Education Associa
