is very satisfactory, affording three times the enjoyment of a simple one-story affair. Fold a three-inch square of stiff red paper diagonally across from corner to corner, making two folds, which cross at the centre of the paper. Unfold and cut the square along the folds almost to the centre (Fig. 269); then pierce the alternating corner flaps with a long, stiff hat-pin, allowing each point threaded on the pin to remain there; run the pin through the centre of the paper (Fig. 270) and shove the red pin-wheel up close to the large round head of the hat-pin. Push a small cork on also, to prevent the pin-wheel from slipping. Work up another cork on the pin, about an inch or so below the first one; then make a larger pin-wheel of white paper and slide it on the same hat-pin, holding it in place with a third cork. Cut the last pin-wheel still larger and make it of blue paper. Shove up a fourth cork on the pin, and below, against it, thread on the blue pin-wheel. No cork will be required under the last pin-wheel; the hat-pin being now pushed firmly into the end of a stick, the blue pin-wheel cannot slide out of place (Fig. 271).
When ready, run with the toy, or whirl rapidly around, holding it in your hand, and see how beautifully the three parts spin, the whole appearing like a whirling red, white, and blue pyramid.

has a button as a foundation. Take a large cup and trace two circles on yellow paper measuring three and a half inches in diameter; make two smaller circles of red paper, two still smaller of green paper, two others—decreasing in size—of yellow paper, and the two smallest circles of blue paper (Fig. 272). Separate the disks into two groups exactly

Select a large button and place it between two vari-colored disks. Be sure to have it in the centre; then with a large pin or needle punch two holes through the disks, covering the corresponding opposite holes in the button. Thread a string through the two holes and tie the ends together (Fig. 273); join the edges of the two disks and the pin-wheel will be ready for action. Place the first two fingers of the right hand in one loop, and of the left hand in the other; give the string a twirl and pull the hands apart. The motion causes the string to twist, allowing the hands to come nearer together; another outward motion of the hands and the pin-wheel will revolve rapidly in another direction. By alternately bringing the hands together and pulling them apart, the pin-wheel can be kept spinning as long as you like. In making the pin-wheel, the paper may be either pasted or sewed; it is firmer when pasted.
