The boat is to be propelled with a single, double-end paddle. There is no danger of the boat capsizing or the water splashing into the barrel.
Homemade Wing Nuts
A handle taken from a worn-out faucet, drilled out and threaded for a bolt, makes a good wing nut. A discarded gas-bracket key, cut off on the line AA and with the part within the dotted lines filed out, then drilled and threaded, also makes a good wing nut.

A Spool-and-Ball Puzzle
Procure an empty basting-thread spool and make a hole in its side, at A, just large enough to receive a 1/4-in. steel ball. A piece of celluloid, B, is wrapped around the flanges, as shown, and fastened with small brads. An old negative film, well cleaned, is suitable for the celluloid. Be sure to put the steel ball in before fastening the celluloid in place.
The difficulty of the puzzle is to get the ball into the hole.—Contributed by R. C. Knox, Waycross, Ga.
