The commentator. Munro Leaf, points out some of the advantages of such farm camps as evacuation centers for citj- children under war conditions. Committee Appraisal: This film provides unusual demon- strations of basic methods, specific techniques, and equip- ment which can be easily obtained or made for the organ- ization and operation of centers for the care and training of children from two to seven. It should be useful in training courses for nursery school, kindergarten, and pri- mary teachers, camp and playground supervisors, and vol- unteer workers in childrens' groups. It should be especially valuable to stimulate interest in, and provide guidance for programs now under way for community care of children whose normal pattern of life has been and will be disar- ranged increasingly by the war. Fighting the Fire Bomb (Transfilm, Incorporated, 9 Rockefeller Plaza, New York City) 14 minutes, 16 mm. sound. Sale price, black and white $38.00, Kodachrome $68.00. Guide furnished. This official training film of the Office of Civilian De- fense tells the story of the fire bomb, what it is, how it is used against civilian populations in war, and how to con- trol it. The common magnesium incendiary bomb is shown, to- gether with actual fires resulting from an incendiary air attack. A burning fire bomb in the living room of a house is brought under control with a home fire extinguisher. The construction of the bomb and the chemical reactions of its burning which require special treatment to control are shown in animation. Proper procedures for controlling magnesium incendiaries and the fires started by them with various types of home equipment; sand, soda-acid, foam- type and pump tank extinguishers are demonstrated under actual conditions in the home. How to make homes less vulnerable to fire bomb attack is shown in detail—the removal of flammable material from attics—sand treatment of attic floors—and installa- tion of proper fire-fighting equipment and training in its use. A series of flashbacks review the facts and skills pre- sented to support the conclusion—the fire bomb can be con- trolled by an informed and trained citizenry. Committee Appraisal: Both the pictorial content and the commentary are convincingly used to show that the fire bomb can be fought and to teach how to fight it effectively and with reasonable safety. Information required for intelli- gent action is introduced in a functional fashion and the necessary skills and proper procedures are demonstrated by members of an average family. An excellent film for teaching the control of the fire bomb to students from intermediate grades through college, to general adult groups, and to special classes in civil pro- tection. Science teachers will be particularly interested in the chemical processes demonstrated in this film. School Made Motion Pictures (Concluded from l^age 235) 6. Why isn't 16mm negative film more widely used in school film production? Any school that has ever tried to work with 16mm negative film can answer that question very quickly. Briefly, the ad- vantages of the negative-positive process for the school are: (1) at no increase in film cost, it permits the original to be pre- served, and (2) it permits the printing of additional copies of the film at about half the cost of reversal dupes. For the school production, however, the disadvantages will weigh much heavier: (1) the negative is extremely difficult for the in- experienced amateur to edit, and (2) it has a substantial ten- dency toward graininess which can become objectionable on the screen. All things considered, the ease of editing makes the reversal films more popular in the amateur field. G. E.
