Admiral ONeil urged that only the bestarmor that could be manufactured should be procured,and concluded his report (Congressional Record, March1, 1899, pp. 2,835, 2,836, and 2,837) thus: The Bureau of Ordnance desires to be placed on record as recom-mending to the Department that only the best quality of armor thatcan be obtained in this country shall be placed on vessels of the Uni-ted States Navy, regardless of price.

ARMOR PLATE FOR THE NAVY. 25 IMPROVEMENTS IN QUALITY OP ARMOR. Admiral ONeil recently submitted a table of ballisticvelocities, showing that the proposed tests for Kruppizedarmor would be such as are now applied to Harveyizedplates of 25 per cent, greater thickness; that is, the sametest will be applied to a six-inch Krupp plate that hasheretofore been applied to a Harveyized plate of seven andone-half inches; to an eight-inch Krupp plate that whichhas been applied to ten-inch Harveyized armor; to a ten-inch Krupp plate that which has been applied to Har-veyized armor of twelve and one-half inches; and to atwelve-inch Krupp plate that which has been applied toHarveyized armor of fifteen inches; the difference in re-quirements being illustrated in the following table of min-imum velocities of feet per second for the Harveyized andthe Kruppized armor—one shot at the Harveyized plateand three shots at the Kruppized plate at given velocity.The test of Harveyized plates also provided for
