Outline maps of states or countries may be made with India ink for use in classes in geography, history, or social sciences. Then they may be projected upon large sheets of manila paper fastened on the blackboard or wall. While the image is projected upon the paper, an outline of the map may be made with crayons or paints. Products, cities, points of interest, life of the people depicted by freehand drawings or clips may be located by different pupils, or the entire map may be painted with calcimine to show valleys, mountains, etc. A detailed master slide might then be used for checking the accuracy of the work of the pupils.
In primary activities, in the study of "Farm Animals" or "Animals of the Circus," the same procedure may be followed. This type of work is particularly valuable in training pupils of these grades in the use of the larger arm muscles. There is no limit to the uses of the India ink lantern slide. Both teacher and pupils will find new occasions for making them each year. The slides may also be preserved from year to year. A library of inked slides which have been made by both teacher and pupils may soon be accumulated for use in each of the different subjects.
