SCIENCE AND INVENTIONS.

C. J. Lynde, Macdonald College, Quebec, Canada. AUTOMOBILE ATTACHMENT. The wheels of the automobile here are replaced by sleigh runners, and the rear axle has at each end a sprocket wheel

Winfer .Auto, / r ** which drives a heavy spur wheel by means of the sprocket chain. This turns the car into a motor sleigh.—Thomas E. Pattereon, Athabaska, Alberta, Canada. (U.S. Patent 1,247,571).

SAW SET. This is a saw set of the plier type, and the improvement lies in the set screw. This is readily adjusted with the help of

the pointer, and gives each tooth the same pitch.—Walter G. Herman, Raymond, Washington. (U.S. Patent 1,242,348). HALTER LEAD. The hook-shaped piece here is made of malleable iron. It clamps the locking ring to the halter rope and also prevents the

Halter. Lead halter ring from wearing the rope.—Joseph W. Hall, Virginia, Illinois. (U.S. Patent 1,239,591). CANADIAN MILK PLATFORM AND ICE HOUSE.
