Photographic Cage By Ernest THompson SETON While the ideal photographs of mammals are made from wild specimens free in their native surroundings, the difficul- ties of such photography are so great and the opportunities so few, the majority of photographs and the best of them on the whole, are made from captive animals. Most of the cages in Zoological Gardens are constructed as though it were intended to make photography impossible. They are ill-lighted and have hideous backgrounds. They have square floors, instead of uneven ground to give variety of pose. They are without provision for eliminating the bars; and it is by luck rather than by management that the animal comes within the range of the camera. After a dozen experiments, I have at length evolved a photographic cage that meets all the difficulties for animals or birds of any size up to a fox or goose. Its plan 1s shown here. To make it, take two pieces of 2 x 2, each 10 feet long; and two pieces of 2 x 4, each 12 feet long; with other pieces of 2x 2, enough to make a box or tube, as in the diagram ABCD. This is Io feet long, with the two lower pieces projecting for a camera shelf DE; 3 feet by 3 at the large end, and 1 foot by 1% at the small end. The sides are boarded up solid with %4-inch boards, from AD to FG on both sides. The whole cage should be floored with inch boards. GFHI is a wire door 2 feet high by 1% feet wide, through which the animal enters, and the acces- sories arranged. The opposite side is covered with wire net- ting. | The side IHBC and its mate on the other ‘side, are of plate glass, as also is the top from H to B. These pieces of plate glass are costly if ordered from the glass dealer; but I find that five or six old wind shields, or door glasses from a “car graveyard” answer very well. If these are too long and
