A New Armor Plate

A LIEUTENANT attached to the Ordnance Bureau has produced an armor plate which was recently tested at the armor-proving grounds with such success that naval officials at Washington believe that the armor has again overtaken the gun in the race for supremacy. The plate is perfected by a novel process by which carbon is driven directly into the face of the hot plate through the agency of a powerful current of electricity. The carbon is driven into the plate to any desired depth, the result being that the plate is made as hard as glass, and this, supported by a tough back, renders penetration almost impossible.
