If you have falconers among your clientele they will welcome this book. There are a surprising number of books on the subject, but, as the author puts it, they all leave out the same things. So he has written his book around the omissions of others, and they seem the basic elements of falconry, including the various kinds of hawks, their habits, capacity for training and hunting ability; false impressions of the havoc they create are corrected, and their value emphasized. Traps and lures are described, study of the country to be hunted over is indicated, and the adaptation of hawk to quarry analyzed. Capture, hooding and training are explicitly described. Kindness in treatment is stressed and throughout the book there is the recurrent plea for falconry as a humane sport, a sport which kills painlessly and quickly.
