He claims that by thismethod his initial pressure does not need to be more thanhalf as great as that used by Captain Zaiinski. He doesnot have to use so much compressed air. nor does he re-quire that the barrel of his gun shall be of such greatlength. His highest pressure is about 4,000 lbs. to theinch, the first pressure being not more than one-tenth ofthat. His detonator is a very ingenious affair, and is in-serted through a small circular opening from the interiorof the gun. The ordnance ofiRcers are much interested inthis new form of the dynamite gun, which is first broughtto public notice, we believe, in this article. VOL.
