Window Anti-Frost Solution

A window glass may be kept from frosting by rubbing over the inner surface a solution of 55 parts of glycerine and 1,000 parts of 60 per cent alcohol. The odor may be improved by adding a little oil of amber. This solution will also prevent a glass from sweating in warm weather.

Using Sandpaper

Sandpaper may be kept from slipping under the hand by chalking the back.

Lay a Match on the Picture

A small chain composed of several links was cut from the wood that forms the match.

Varnish For Electric Terminals

A good varnish for electric terminals is made of sealing wax dissolved in gasoline. To prevent brittleness add a little linseed oil.

Arbor Wheels

Emery wheel arbors should be fitted with flanges or washers having a slight concave to their face.

Saving A Brush

If a round brush spreads too much, slip a rubber band over the upper part of the bristles.

Right Handed Engine

Standing at the cylinder end and looking toward the flywheel of an engine, the wheel will be at the right if the engine is right-hand.

Kitchen Knife Sharpener

A good serviceable knife sharpener may be made from a piece of steel cut as shown with two screw holes drilled for fastening it to a piece of wood or to a table. The knife is drawn through and sharpened on either side. Both positions of the knife are shown. The steel is hardened before fastening it in place. --Contributed by George Madsen, Chicago. Ill.

Adjuster For Flexible Electric Wires

The accompanying illustration shows an adjuster for changing the drop of an electric light. The main feature of this adjuster is that it can be removed from the cord at any time. The adjuster is made from a piece of wood, 3/8 in. thick, 2 in. wide and 3 in. long. A 1/4 in. hole is bored in the center near each end of the wood and a slot cut from the holes to the outside edge, as shown in Fig. 1. It is attached to the flexible cord as shown in Fig. 2. --Contributed by J.J. Voelcker; Decatur, Ill. Can Be Taken from the Cord

Home-Made Roller Skates

The rubber-tired wheels of an old carpet sweeper can be used to advantage in making a pair of roller skates. In Fig. 1 is shown how an iron washer or two may be fastened to the wood with a piece of sheet metal to support the short axles of the wheels. The wheels are oiled through the holes A and B, Fig. 2. These holes should be smaller than the axles. The two side pieces are fastened together with a board nailed on the top edges, as shown. This board also furnishes the flat top for the shoe sole. Two straps are attached for fastening the skate to the shoe. --Contributed by Thos. De Loof, Grand Rapids, Mich. Rubber Tired Roller Skate

Blue Dye

Prussian blue and Chinese blue are both the same chemically but they do not cut or look the same.

A Window Lock

Bore a hole through the sash of the lower window and halfway through the sash of the upper window, where they meet in the center, and insert a heavy nail or spike. This will fasten the sash together so well that nothing short of a crowbar can pry apart. The nail can be easily removed when the windows are to be opened.

How To Carry Books

Almost all school children carry their books with a strap put around and b u c k led very tight. This will make dents in the cover where the board overlaps the body of the book. If the strap is left loose, the books are liable to slip out. Place the cover of one book between the cover and fly leaf of its neighbor and the difficulty will be remedied. This will place the books in alternate directions. Books stacked in this manner do not require the strap buckled tight, or, they can be carried without any strap just as well. --Contributed by Thos.

Bottle Pushers [409]

Bottle Pushers

Bottle Pushers 727

BOTTLE PUSHERS. --This is a game in which the competitors push bottles on the ice with hockey sticks. All the bottles must be the same size and make. The persons participating must keep their bottles upright at all times. The bottles are lined up for the start and at the word "go," each person pushes a bottle across the field for a distance that is agreed upon.

A Phoneidoscope

The phoneidoscope has many and varied forms, but the simplest can be made by bending the forefinger and thumb so as to form a circle and then drawing a soap film across the opening. This is done in a manner similar to the blowing of soap bubbles. The angle with the direction of the light may be readily adjusted by turning the wrist, a motion of the elbow alters the distance from the mouth and the tension of the film can be regulated by moving the thumb and forefinger. Singing or speaking at the film when under proper tension will cause beautiful figures to appear, which may be reflected from the film directly on the screen. --Contributed by Robt. E.
