Reel and Slide (Mar-Dec 1918)

22 REEL and SLIDE Stereopticon Invades New Fields of Teaching {Continued .from page 20) The first and quite the most efficient of these is the projection of still pictures from lantern slides, and there are many sources of supply from which slides may be obtained. There are, first and foremost, distributed here and there over the country, several great commercial collections of lantern slides. These collections usually represent years of study and endeavor on the part of their compilers to assemble the most satisfactory pictures. As a rule, slides from these collections can be either purchased or rented. In the latter case, the renter is held responsible for any breakage which may occur and for transportation charges both ways, from and back to the source of supply. These collections are usually complete and right up to date. From the viewpoint of practical pedagogy, they offer a wonderful variety of selection. The source of supply which is becoming more general and efficient, is the state bureau or division of visual instruction. Not all states have such bureaus, but a number of them have, and they are becoming more general all the time. These bureaus are endeavoring to select from the above collections and from other sources shdes, arranged in sets, or in combinations, which they send out at a nominal rental charge to schools and educational institutions all over their respective states. KnUBUIUlIll Usually, the circuit plan is adopted in this distribution. In some instances, public libraries have collections of lantern slides to which they are constantly adding and which may be rented to churches and schools in the same town or county. Atlas Produces New Picture on Farm Help Problem THE Atlas Educational Film Company will soon release their new two-reel subject, "Solving the Farm Help Problem." This film is calculated to give practical information to the farmer so that he may introduce a greater degree of efficiency into his management and increase the production of crops — at the same time reducing the number of his helpers. The picture was directed by C. A. Rehm of the Atlas Company, in which work he has been benefited by the advice of expert agriculturists. Slide Service Now on Basis of Complete Efficiency By B. J. Knoppleman TEN thousand slides are produced in New York City alone every day of the year ! Eighteen thousand theaters are showing slides to 20,000,000 people throughout the land, and practically every school, church, community center and college in the United States either uses the stereopticon regularly or occasionally. Slide distribution service as now -offered by many leading slide makers is on a par with the most efficient film distribution. The problems of the slide advertiser are strikingly similar to those of the film advertiser. Each field aids the other. Hundreds of concerns use both, adopting each medium for its individual benefits. The problem of distribution on a lantern slide campaign has been solved very easily, and it offers not only a fully efficient, but also an inexpensive medium by which great masses of people can be reached. In the first place, lantern slide advertising differs from most other forms of advertising in that an audience must read the slides and concentrate on them. When a slide is thrown on the screen in _a darkened room, the screen is the center of interest. The truth of the matter is, lantern slide advertising is one of the most economical and effective forms of publicity known. The principle of slide advertising as employed by big national advertisers is this : Let us suppose that you are a manufacturer of automobile tires ; and you sold through garage men and accessory dealers. You would furnish each of your dealers with one or a number of lantern slides, which include their name and address and they in turn would pay for their projection on the screen in their local moving picture theaters. You do not have to trouble yourself with the shipping of the slides to your dealers. The slide maker takes care of that for you. Clients furnish the names and addresses of their dealers, and the -slide company mail the slides in specially prepared cartons, charging only for postage.
