The educational screen (c1922-c1956])

330 The Educational Screen iblc advertising matter appears in the film, however, and the subject is one splendidly adapted for rural audiences. \ farm advisor, seeing the farmer about .o tack up a sign on his mail box, "Farm tor Sale." shows the owner what the trouble is. He tests the soil with litmus paper and acid, and the results show that the soil is both acid and sour. He ad- vises the farmer to use limestone, and to onvince him of the beneficial results vxhich would follow, the farm advisor takes him to visit a neighbor's farm. A machine is spraying pulverized limestone over the field, and the visitors inspect crops of clover and corn grown on land treated with lime before planting. The stock are also benefitted by the increased amount of nutrition in the feed. The farmer, convinced by what he has seen, conies home and takes down the sign, after ordering limestone for his worn- out soils. Land Clearing (3 reels) Distributed by alichigan Agricultural College, and the Department of Agriculture at the Univer- sity of Wisconsin. The reels can also be bought from the University of Wis- consin. Originally covered with white pine, these lands have been overgrown with brush which must be cleared. For larger growth, the scythe and ax are used, the brush is piled and cut and the waste burned. "Brushing" is sometimes done by pasturing on the lands to be cleared. Burned stumps are removed, and various methods of stumping are shown in detail. The stump-pulling machine is seen in operation, both on green stumps and on those which are old and partly rotted. In the case of the latter, a root-hook is sometimes necessary. The proper time for stumping operations is shown to be when the small roots have rotted but the main body of the stump is still solid. The second reel shows the use of dyna- mite in blasting, the sharp-pointed iron bar making a hole deep under the stump in firm soil, and the placing of the cart- ridges in the hole with the fuse cartridge on top. Animated diagrams indicate clearly the method of preparing the charge under the stump and the wiring. The two films above are typical I examples of films which are being used to enormous advantage in the field of rural education. Our great railroad companies, for example, are doing big things in developing more intelligence in agricultural methods throughout the vast tracts of country served by their lines. For the viewing of the above films we are indebted to Mr. W. H. Hill, Agricultural Agent of the New York Central Lines. MISCELLANEOUS Sketchographs (Educational Films Cot poration)—This one, called "What's th Limit?" is a cartoon history of war fror early times to the present. It shows th contests of the ancients, who glorifie war, in contrast with the way in whici war is waged today, judging by its result in the cases of the Lusitania and th Rheims cathedral. Cartoons follow, pic turing the cost of the World War to th belligerent powers, and the resulting loa< of debt. Not the least convincing is th cartoon sketched to show the large per centage of taxes (over 95%) spent fo war, and the small percentage in contras spent for education and health. A telling piece of visual argumeo against war, skilfully done in sketch styl< with some supplementary titles. MOVIES AND THE LIBRARY (Concluded from page 318) film is shown in the neighborhood.
