But the wonders of nature which the camera unveils to us are not limited to those which the naked eye can follow. The technical progress led to the attachment of the microscope. After overcoming tremendous difficulties, the scientists succeeded in developing a microscope kinematography which multiplies the dimensions a hundred thousand times. We may see on the screen the fight of the bacteria with the microscopically small blood corpuscles in the blood stream of a diseased animal. Yes, by the miracles of the camera we may trace the life of nature even in forms which no human observation really finds in the outer world. Out there it may take weeks for the orchid to bud and blossom and fade; in the picture the process passes before us in a few seconds. We see how the caterpillar spins its cocoon and how it breaks it and how the butterfly unfolds its wings; and all which needed days and months goes on in a fraction of a minute. New interest for geography and botany and zooelogy has thus been aroused by these developments, undreamed of in the early days of the kinematograph, and the scientists themselves have through this new means of technique gained unexpected help for their labors. The last achievement in this universe of photoknowledge is "the magazine on the screen." It is a bold step which yet seemed necessary in our day of rapid kinematoscopic progress. The popular printed magazines in America had their heydey in the muckraking period about ten years ago. Their hold on the imagination of the public which wants to be informed and entertained at the same time has steadily decreased, while the power of the moving picture houses has increased. The picture house ought therefore to take up the task of the magazines which it has partly displaced. The magazines give only a small place to the news of the day, a larger place to articles in which scholars and men of public life discuss significant problems. Much American history in the last two decades was deeply influenced by the columns of the illustrated magazines. Those men who reached the millions by such articles cannot overlook the fact--they may approve or condemn it--that the masses of today prefer to be taught by pictures rather than by words. The audiences are assembled anyhow. Instead of feeding them with mere entertainment, why not give them food for serious thought? It seemed therefore a most fertile idea when the "Paramount Pictograph" was founded to carry intellectual messages and ambitious discussions into the film houses. Political and economic, social and hygienic, technical and industrial, esthetic and scientific questions can in no way be brought nearer to the grasp of millions. The editors will have to take care that the discussions do not degenerate into one-sided propaganda, but so must the editors of a printed magazine. Among the scientists the psychologist may have a particular interest in this latest venture of the film world.
