New Artillery Company. – A specimen of the brass field pieces, intended for the use of Capt. Thos. T. Croppers' Artillery company, was exhibited on the Capitol Square yesterday, to a large number of interested spectators. It was made at the Tredegar foundry, of brass, and weighs, as the others will, 175 pounds each. On trial, first round, with twenty musket balls, scattered about twenty feet in 200 yards; with forty balls, about thirty feet, and with sixty balls, thirty seven feet. It would cut in infantry a perfect lane. Capt. Cropper expects to use ten of these guns. They shoot with a single ball, with accuracy, over one mile. Capt. C.'s office is opposite the Law Building, Franklin street.
