Cardboard Spiral Turned By Heat

A novel attraction for a window display can be made from a piece of stiff cardboard cut in a spiral as shown in Fig. 1. The cardboard should be about 7 or 8 in. in diameter. Tie a piece of string to the center point of the spiral and fasten it so as to hang over a gas jet, Fig. 2. A small swivel must be put in the string at the top or near the cardboard, if it is desired to have the spiral run for any length of time. The cardboard will spin around rapidly and present quite an attraction. --Contributed by Harry Szerlip, Brooklyn, N. Y. Spiral Cut from Cardboard

Staining Wood

A very good method of staining close-grained woods is to use muriatic acid. The acid is put on with a brush like any ordinary stain. The colors thus obtained are artistic and most beautiful, and cannot be duplicated by any known pigment. The more coats applied the darker the color will be. This method of staining has the advantage of requiring no wiping or rubbing. --Contributed by August T. Neyer, One Cloud, Cal.

How To Remove Paper From Stamps

Old stamps as they are purchased usually have a part of the envelope from which they are taken sticking to and in removing this paper many valuable stamps are torn or ruined. Place all the stamps that are stuck to pieces of envelopes in hot water and in a short time they can be separated without injury. Dry the stamps between two white blotters. Stamps removed in this way will have a much better appearance when placed in an album. --Contributed by L. Szerlip, Brooklyn, N. Y.

The Rolling Marble

Take a marble and place it on a smooth surface, The top of a table will do. Ask someone to cross their first and second fingers and place on the marble as shown in the illustration. Then have the person roll the marble about and at the same time close the eyes or look in another direction. The person will imagine that there are two marbles instead of one.

Taking Button From A Child's Nostril

A three-year-old child snuffed a button up its nostril and the mother, in an attempt to remove it, had caused the button to be pushed farther up the channel. Doctors probed for the button without success. The distracted mother happened to think of snuff, and, as there was some at hand, took a pinch of snuff between the thumb and forefinger and held it close to the child's nose. The violent sneezing caused the button to be blown out. Such an accident may come under the observation of any parent, and if so, this method can be used to relieve the child when medical assistance is not at hand. --Contributed by Katharine D.

How To Chain A Dog

A good way to chain a dog and give him plenty of ground for exercise is to stretch a clothesline or a galvanized wire between the house and barn on which is placed a ring large enough to slide freely. The chain from the dog's collar is fastened to the ring. This method can also be used for tethering a cow or horse, the advantage being the use of a short tie rope eliminating the possibility of the animal becoming entangled.

A Plant-Food Percolator

Obtain two butter tubs and bore a large number of 1/4-in. holes in the bottom of one, then cover the perforated part with a piece of fine brass gauze (Fig. 1), tacking the gauze well at the corners. The other tub should be fitted with a faucet of some kind -a wood faucet, costing 5 cents, will answer the purpose. Put the first tub on top of the other with two narrow strips between (Fig. 2). Fill the upper tub, about three-fourths full, with well packed horse manure, and pour water on it until it is well soaked. When the water has percolated through into the lower tub, it is ready to use on house and garden plants and is better than plain water, as it adds both fertilizer and moisture. -Contributed by C. O.

Repairing A Cracked Composition Developing Tray

Fill the crack with some powdered rosin and heap it up on the outside. Heat a soldering-iron or any piece of metal enough to melt the rosin and let it flow through the break. When cool, trim off the surplus rosin. If handled with a little care, a tray repaired in this manner will last a long time. The chemicals will not affect the rosin. -Contributed by E. D.
