FRESH-SHINGLED Doctors of Medicine commonly take the Oath of Hippocrates and thus subscribe to a code of medical ethics. There has been proposed a similar oath for scientists, whereby they would swear by whatever gods or immutable truths they hold sacred to work only for the welfare of mankind, and to avoid that scientific sin which is secrecy—military or national.

THIS LUMBERING MONSTER, the largest tank ever built for the U.S. Army, was designed to crack Germany’s West Wall — but American troops were behind that fortification before T-28 could fire a shot. Recently unwrapped at Aberdeen Proving Grounds, it weighs 100 tons, mounts a 105-mm. gun, is already obsolete for atomic warfare.

IN CHICAGO there is a steely-faced banker who would rather duck into his cellar on a sunny Saturday than shoot 19 holes of golf. In Hollywood there is a movie actor who prefers tinkering with old clocks to night-clubbing along the Strip. In Boston there is an auto mechanic who passes up the movies to sneak back to the shop and whittle bronze into chessmen.

To do this, two differentials are housed one within another; the first to drive the rear wheels, the second to level the tractor.

HERE is a ring-and-peg game for indoor play on rainy days. The base is ½" plywood, as is the glued or nailed center disk with the short peg. Mark the base radially and paint the spaces black and light blue alternately; then number the long outer pegs 1 to 4, the disk 5, and the short peg 10. Cut three rings from 14-ply show-card stock.

BETTER—and easier—weed-killing is promised by the new, three-foot-long weeder, above, made by the S K G Corp., of Minneapolis. It is operated by thrusting its forked blade under a weed to sever the roots. The spring-action trigger under the handle is then snapped and the claw closes on the weed to grip it when the blade is pulled out of the ground.
