Ferrotype tins may be stored in the manner shown in the illustration, but ferrotyped prints can not be dried in this manner. The fan (with or without a heating element) is still used with satisfactory results, although there are some very good drying cabinets in use now. 23. Shelf-space is very valuable, and it is important to keep trays and containers in a familiar spot where they may be found readily. 24. If stock chemicals are stored in this manner, it is easy to find them and also easy to determine when they need replenishing. 25. Film Developing Chemicals should be kept in a separate place and the fixer should never be used for developing both prints and films. The drawers may be used for storing the things which are needed to complete tests or jobs. In this school laboratory, the drawers contain: print tongs diffusion discs litmus paper towels film filter paper lenses opaque printing paper stirring rods etching knife paper for scales pens Scotch tape labels for bottles brushes masking paper corks film clips formula books squeegee pencils ruler absorbent cotton erasers rubber bands tissue paper crayon sauce CAMERA ACCESSORY FOR WILD LIFE PHOTOGRAPHY The photography of wild life usually calls for extreme caution and care on the part of the cameraman. In most cases it is impossible for him to approach birds and animals sufficiently close to secure a reasonably large image on his film, hence some device which permits camera control from a distance has long been recognized as a definite and necessary aid to the nature photographer. E. Leitz, Inc., 60 East 10th St., New York City, announces that local dealers everywhere are in a position to furnish a special remote control device for the Leica camera. This equipment is simple, positive and accurate. It merely attaches firmly to the Leica camera in a few seconds, and is easily removed at will. The Leica remote control device consists essentially of a pulley arrangement of which two cords release the shutter and rewind the film and shutter for the next exposure. The length of the cords can be increased to any length required, and permit the cameraman complete and easy control over the action of the camera mechanism. The recommended method of using this equipment is to mount the Leica securely upon a tripod or similar sturdy support so that the camera lens — usually a telephoto lens — is focused directly upon the nest or other area where the subject is expected to appear. The cords controlling the remote control device are adjusted and carried back as far as is convenient or safe, where the photographer can manipulate them without disturbing the wary subjects he wishes to photograph. If your local dealer is not supplied with the new Leica remote control device, write to E. Leitz, Inc., for Circular 7587 which gives complete details.
