The above booklets are published at 10 cents each, and should be in the hands of every camp leader, also the latest guides in Baseball and Tennis.

At Home in the Water—George H. Corsan. Association Press, 75 cents. Twenty pages of this excellent book are devoted to water sports, and it also contains complete rules for Water Polo, a splendid game for adults, but unwise to play in a boys' camp.

The Birch Bark Roll—Ernest Thompson-Seton. Doubleday, Page & Co., 25 cents.

Two Little Savages—Ernest Thompson-Seton. Doubleday, Page & Co., $1.75.

These books give valuable hints on Archery, which is peculiarly adapted for camp life and sport.

The Witchery of Archery—Maurice Thompson. Charles Scribner's Sons, $1.50.
Fascinating and entertaining.
