Submarine building will have to be revolutionised if the invention of E. A. Kritsch, of Sacramento, United States of America, accomplishes all he claims for it. A small model, in a recent test on the Sacramento Rker, trapped, bold, and destroyed a miniature submarine in less time than the inventor claimed tliat it would. Patents are now pending on his invention, and the Italian Ambassador atWashington, on behalf of the Italian Government, will make an offer for the invention if tests to be made are successful (reports the ' Sun Francisco Chronicle). The invention of Kritsch is a submarine trap. The device fastens to the undersea craft firmly. At a specified time, gauged by clockwork, the device will blow up the enemy vessel. It is so mechanically arranged that it clamps itself, to the boat, automatically shutting off its own power. The trap is constructed so that floating air chambers support a steel framework of bolt locks and clutches The framework contains the electric buttery devices opera* ting the alternating air chambers and explosive. The trap is inexpensive. It is self-propelling, and, once' started, will remain afloat an indefinite period,
