SCIENCE AND INVENTIONS.

RECENT INVENTIONS OF INTEREST TO AGRICULTURE. (C. J. Lynde, Macdonald Collego, Quebec, Canada.) SPRAY BETRAYS SUBMARINES. This invention deals with a su'bjeot -which interests us all at this time. Tho floats are so attached that they throw up a spray

Sub JJstectar when the net is moved, and betray the submarine to the patrol boats. The boats then destroy the submarine by depth bombs.—William A. Stewart, East Orange, New Jersey. U.S. Patent, 1,242,386. SIMPLE ANIMAL POKE. This poke is made from three lengths of stout wire bent as shown. Make a model out of light wire to get the proper

lengths and then make one for use out of stout wire.—Edgar G. Goff, Chattanooga, Oklahoma. U.S. Patent, 1,241,842. THE LAMP PREVENTS FREEZING. The metal box of this heater opens and closes at the bottom and is made watertight by means of a gasket and thumb

Borews; It has pipes for, the inlet and outlet of air, also one for oil, and one for the wick regulator. The oh\ pipe has a float indicator to show when the lamp is ; full. —N. D. Riemenschneider, State Center, lowa. U.S. Patent, 1,241,555. HAND PROTECTOR FOR STEERING WHEEL. The pad here is made preferably of tanned sheep skin with the wool side out. It is sewn to a thin sheet metal frame, which

prevents it from sliding, and it is attached to the rim by straps.—Elmer Clarence Burrows, Basin, Wyo. U.S. Patent, 1,235,549. SUPPORTS THE STRAINER IN TWO POSITIONS. • The object of this invention is to provide a support which will hold the strainer above the top of the separator bowl when the

bowl is to be entirely filled, or below the top when this is not the case. —John Trond Svaren. Fayette, N. D. U.S. Patent, 1,241,573. STORM DOOR WITH CANVAS SIDES AND ROOF. The new feature of this storm door is that it has sides and roof of canvas or other cloth. Tho advantages claimed are

that it is easily taken down and put up and that it is cheap.—Burton Herbert Gedgo, Anderson, Indiana. U.S. Patent, 1,230,148. You may never use one of these ideas in exactly the way described hero each week, but you will certainly use many of v them in your own way, to make farm work easier.
