Scarcely have the first men scrambled out of the conning tower before a pursuit-speed, single-engined giant drops out of the clouds. The plane opens its capacious belly bomb bay; out tumble depth charges, and the erstwhile wolf of the sea becomes just another oil slick.

JAPAN sits astride the most unstable piece of crust on the earth’s surface. It has 30 active volcanoes, to say nothing of hundreds that jut skyward in uneasy slumber. Earthquakes are as numerous as shooting stars in August. Hardly a day passes without some of Hirohito’s dupes feeling the earth wobble beneath their feet.

A CROSS-SLIDE SHIELD on a lathe may help to prevent damage to the cross-feed screw. On certain lathes, advancing the cross slide eventually uncovers this screw and thereby exposes it to chips which may work into the threads. Protection against this may be secured by a celluloid shield which is held by a bolt to the cross slide.
