The new 15in dynamite Zalinski coast defence gun which the Gorernment of Victoria have purchased from the Pneumatic Dynamite Gun Company of New York was tested at Cold Spring, up tie Hudson river, on the 9th ult., writes the ■"Argus'" London correspondent. It we *<*hs 40 tons, is 50ft in length, with an inside diameter of 15in M and its carnage weiche another 40 tons. The contract under wWch the gun was constructed require* that it should be able to throw a charge of 1001b of dynamite in an 8m shell a distance ,of 3200 yards, with compressed air as a wotive power. The Pneumatic Company wm forbidden to throw shells loaded with dynaimte, and consequently substituted a composition of equal weight made up of sand and ashes. The following particulars ot the trial have been cabled over :—■ After two or three preliminary trials four shots were made #p * distance of 3200 yards up the river, 'fhree levers worked by an engineer standing on p. high platform fired the gun, raised wad lowered the breach, and moved the carriage. A motor supplied the power, and an air compressor stored the Hi' m a series of 16in iron pii**, the air being *t £ pressure of 20001b to tlie square inch, Th£ air is passed from this reservoir to a rseooftd one, and then allowed to pass to •the fcwech of the gun behind the shell by : a complicated system of valves. In the ■first. sfctft;t?je projectile revolved consider-1 ably after -reaching its greatest height, and in ii?e inrtrd., owing to some mistake in fillin" the sheft, ft broke when near the end of "its flight- The :^cond shot was made with a lOin shell, fl«H» long, and weighing 5291b,5. This riieii ww intended to contain 2001ns of dynamite, *nd made a beautiful tfight of about two I miles. Its course was straight, and there was not a single revolutions pf the shell. As it ir-rived at the highest point «f the curve, it turned and fell perpendicularly into the river in 21±sec. The initial and Anal pressure 10001b and 8501b x-^pectwdy, Ll fcho elevation 33 deg 44 win. The last tshot was Diftde with ani 8m fchell. The projectile sailed gracefully upward at an angle of 30 deg. 43 jam. When at a point about two miles and « fcajf from the muzzle it turned and fell stiyvig :*fc fts an arrow into the river. The untaalpwsjww on the cylinder of the gun was found to be only 8761b, and the final pressure 7451b. The representative of the manufacturing company «,wl that the gw« would be sold for alHiut 50,W0 dot. He added that five more guns of tliW kind were in process of construction lm the L uitecl States Government.
