In offering the following pages, it has been my aim to show the necessity for the establishment of steel gun factories in the United States; to extend the information collected, and the conclusions reached, by the Gun Foundry Board; and to provide a book of easy reference to the details of the manufacture of modern ordnance.
In thanking all who have assisted me in the preparation of this work, I wish especially to acknowledge the benefit of my association with Rear-Admiral Edward Simpson, U. S. Navy, and the other members of the Gun Foundry Board.
In addition to those authorities cited by name, as well as by the establishments with which they are connected, I desire to thank
Brig-General S. V. Benét, Chief of Ordnance, War Department,
Captain Montgomery Sicard, Chief of Ordnance, Navy Department,
Mr. James M. Swank, Secretary of the American Iron and Steel Association,
Lieut-Commander F. E. Chadwick, U. S. Navy, Naval Attaché, London, England,
