Another monster gun cast.
--Another monster gun was cast at the Fort Pitt works on Wednesday.
The ‘"
Floyd, "’ the heaviest piece of ordnance, we believe, that the world has ever seen, was fifteen inch bore and forty-nine inches in diameter at the breach.
Its weight in the rough was seventy-eight thousand pounds, and when finished, about forty-nine thousand.
The gun cast on Wednesday has a twelve inch bore, and the same exterior diameter of the ‘"
Floyd," ’ while it is six inches longer, and will weigh, when finished, twenty-five tons.
The total amount of metal used in the ‘"run"’ was seventy-eight thousand one hundred pounds. The new gun will be named ‘"Union,"’ and will, it is believed, throw a ball over six miles.--
