Sir: The Board of Engineers has submitted a report presenting records collected from time to time of practice abroad with the heavy Armstrong, Woolwich, and Krupp ri?ed guns. The results are tabulated for easy reference, and exhibit a large range in powder charges, initial velocities, and striking energies of the projectile from the earlier to the latest trials.
The paper contains valuable information for the officers of the Corps of Engineers and for the Army generally, and I respectfully recommend that authority be granted to have it printed, with its accompanying plates, at the Government Printing. Office, as a Professional Paper of the Corps of Engineers, and that copies be obtained for the use of the Engineer Department upon the usual requisition.
In view of the permanency of its value, and to save expense of composition, in case that future editions are called for, I further recommend that the work be stereo typed.
The report, with accompanying tables and plates, is submitted herewith.
