Catechism on Field Training (Infantry). Revised and brought up to
date by Colonel H. O'Donnell. (Gale and Polden. 3s. net.) —New editions of the regulations have made necessary a complete revision of this Catechism. It is one of those handbooks which are indispensable to officers and non-commissioned officers, and might well prove serviceable to others besides regulars. Questions concerning field engineering, camps, &a, are practical—e.g., "how would you know whether a certain bridge could carry a field gun or ordinary vehicle ?" Or, " What should be done with water in which potatoes have been boiled ?" A. " Use it for washing up." —The Non-Commissioned Officers' Guide to Promotion (Gale and Polden, 3s. 6d. net) is another revised edition. Since this book is equally as valuable to Territorials as to Regulars, might not a better introduction be devised for it than a letter recom- mending it to garrison libraries from the late Duke of Cambridge ?
