Major Lefebure, scientist and engineer, was active in the Chemical Warfare Service throughout the First World War. After the war he visited the German Chemical factories. He made every effort to bring his findings clearly before the peace delegates. He came to America to be in complete understanding with our War Department.  He then wrote this book, which is of vital importance to all peace loving citizens.
