e turns in them. A MECHANICAL PAPER BIRD. The art of making paper articles would necessitate along study on our part, and we do not intend to enter onthe various phases of it here. , We know that manythings can be made in paper, but the particular objectwhich we are about to explain is a mechanical birdintroduced by the Japanese jugglers—a bird which willflap its wings when manipulated. The illustration showsthe action of the hands, which, approaching arid separating I30 MECHANICAL TOYS, ETC. alternately, make the bird flap its wings. The otherdesigns indicate the progress of construction as follows :—Take a sheet of ordinary writing paper and cut it sothat it will form a perfect square. Fold this, as indicatedin No. I, by the middle and the angles, and then turndown the angles as in 2, emphasizing the fold strongly,following a b only, and operating in this way on bothsides of the four angles. You will then have turned downeight folds like a b, and your paper will have assumed the

Then fold the paper asNo. 4, so as to accentuate the folds, which can be pressedwith the nail; it will then be easy by fastening the foldsaround the centre c to obtain fig. 5 from 4. Then turnthe paper upside down, and bring up the two oppositefolds as in diagram 6, and proceed to raise the points rightand left, thus forming diagram 7. By extending thepoints d and / to right and left you will produce theappearance of the bird as in diagram 8.
