HOME MOVIES FOR AUGUST PACE 343 with cork linings and yanked out the insulation. From their work, the servicemen formulated remedies. One of the best solutions to the moisture problem was found to be the dry, hot room or "hot locker" for storing equipment. Now in most tropical areas, the servicemen have constructed small buildings of light board, and installed rows of electric light bulbs or other type of electric heaters in the rooms. Rooms are kept as air-tight as possible, with a vent in the roof, and by holding the humidity at less than 40 per cent, the corrosion, rust and fungus are cut to a minimum. This procedure is now regularly recommended for storage of all optical equipment in the tropics. On the basis of the field men's reports, base plates and heating surfaces of camera magazine, which used to be of bare aluminum and magnesium, are now anodized and dichromated. Steel plates are cadmium plated wherever possible. Only the most critical heat-treated parts are not cadmium plated because of the impossibility of machining them to the proper tolerance when plated. These parts, however, are in the minority, and can be carefully watched for rust formation. Tested glues are now being used in place of the old animal glues, and heavy felt padding has been eliminated from carrying cases and trunks to prevent retention of moisture and the growth of fungus. Cork linings have been eliminated from heated cameras, and an outer jacket constructed of fiber glass and tested for its fungus-resistance properties, has been substituted. Experiments are being conducted in the University of Pennsylvania's "jungle laboratory" by Dr. W. G. Hutchinson, and he has submitted a fungicide which the Fairchild company is giving further tests in the field by incorporating it with glues and lacquers. This fungicide showed "very promising" results after exposing the equipment coated with it in the tropical jungle room. * ★ ★ Setting a precedent which may well be followed by other philanthropically inclined individuals, is the gift of visual aids materials recently presented the Los Angeles Board of Education by Tom May, department store executive. Four sets of 16mm. prints of the 15 "Chronicles of America" photoplays; 1 1 sets of lantern slides; and numerous sets of historical volumes comprised the gift. "The May Company makes this gift to the children of Los Angeles city and county so they more fully understand the greatness of their heritage," May stated in making the presentation.

A small amount of experimenting will be found necessary to determine exactly how heavy the weight (A) should be to give the desired pressure. — Arthur Pv. Mcllor, Pawtucket, R. 1. Faded Coloi Film If you have any faded Kodachromc containing valued scenes or shots, here is a method by which you can preserve the record, restoring it to its original worth, although not in color. Provided the film has not too great a brightness range or is not too dense, a satisfactory copy of it can be made in black and white, using positive film. Because the positive emulsion builds up high contrast, the faded appearance in the original will be removed in the black and white copy. — Stanley Jcpsou, Bombay India. Remedy For Error Here is an idea for scenes which have been over-exposed but cannot be refilmed, and where it is not desirable to tint or dye them. Just in front or in back of the film gate insert a piece of colored celluloid of sufficient density to equalize the extra amount of light resulting from over-exposure. If the film appears best without this added color, neutral density instead of color filters or celluloid of a gray or neutral tone can be used ahead of the lens. — Fred Robertson, Jr., Pouqhkeepsie, N. Y. • Safe Wiring Addi tional safety as well as convenience is afforded when all the wiring in the photographic darkroom goes through one conveniently located master switch. This can be placed near the door or entrance to the dark room and so wired as to control the electric current in all parts of the room. When the switch is turned off, all the little pilot lights, safelight, printers, and all electrical apparatus is likewise turned off simultaneously. None is left on to burn out, cause trouble through short HEAP GOOD /9 „ TRADE wiih Get off the reservation and come down to my store for a real pow-wow and trade. Or write me.
