The Art of Shooting, by C. Lancaster. The diagrams in this book are most valuable and practical, and there are many useful hints.
The Badminton Library, Shooting, 2 vols. The chapters dealing with Pheasant shooting are particularly good.
The Fur and Feather Series, The Partridge, a book as delightful to read as it is useful to study.
Hutchinson on Dog Breaking, a book which has never been approached, much less surpassed.
Daniel's Rural Sports, to be found in most country house libraries, a thoroughly useful and practical book from which many subsequent writers have borrowed. It deals of course with sport from an old-fashioned point of view, but is none the worse for that.
Tegetmeier's Pheasants, a first-rate standard work, by an expert.
Now let me give a few useful cautions to young shooters:
Don't point your gun at anything but the game you wish to shoot.
Don't risk a shot if you have doubts as to its safety.
