When exhibiting the pictures, place the box on a table with its front well lighted, turned toward the audience, and turn the pictures slowly, by an even motion of the cranks, pausing slightly at each scene, at the same time giving, if possible, a brief description of the thing illustrated, as this will add considerably to the enjoyment of the little folks. I forgot to add, in its proper place, that for a final finish the whole thing should be covered with any pretty paper at hand. Nice wall-paper or even common brown wrapping-paper gives it a neat appearance.
Having thoroughly mastered the construction of the simpler form of the panorama, a more elaborate one can be made by simply devoting to it considerably more time and attention; but as this is greatly superior to the other in every respect, it is well worth the extra trouble.
This will necessarily require a much larger box than the one previously described. For convenience in description, suppose we have a soap-box two feet long, twelve inches high, and eighteen inches wide. We shall first take away both top and bottom, then standing it upon its side, we have the frame-work of our structure, which is still two feet long, but now eighteen inches high, and twelve inches deep, that is from front to back; next, we cut from the discarded top a false bottom, or shelf, like Fig. 2, which, if your box is of seven-eighths inch material, will measure twenty-two and a quarter, by eight inches. Mark the point _a_, four inches from one side of the board, and equidistant from the ends; through this draw the line _b c_, five inches long on each side of _a_, or ten inches in all; mark at three and one-half inches from the ends of the board the points _d_ and _e_, and draw the lines _b d_ and _c e_; then cut out the piece thus marked off.
The holes at the bottom for the rollers are four and one-half inches from the back _f g_, in order to insure that the line of pictures when in motion shall not fall back from the line _b c_, and are equidistant from the ends of the board and the oblique lines _b d_ and _c e_, to secure as much room as possible for the roll. Make corresponding holes in the top of the box, taking particular care that they are exactly above those in the shelf, when that is in position. The rollers are made from sections of broomstick, with holes bored in the ends, and the wooden pins glued firmly in place. Remember that the upper set of pins are to be much longer than the lower to allow for the insertion of the crank. These rollers are about eleven and one-half inches long, and when the glue has thoroughly dried, should be put in place and kept there by inserting the shelf, and fastening it in place by nails driven through the sides as at _i i_, in Fig. 3.
