The Riders. By A. Russ= and Frederick Boyle. (Frederick Warne

and Co.)—This is, in a way, a continuation of "The Orchid-Seekers in Borneo." Ludwig Hertz is one of the prin- cipal characters, and he goes to look for the Cattleya, a peculiarly splendid specimen of the tribe, in the country of Costa Rica. With him go the hero or heroes of the story, and there they meet the great filibuster, Walker, if filibuster he was. Some people thought him more of a crusader, only that the symbol of his faith was the Stars and Stripes, as signifying liberty. In or out of Walker's company, but always influenced by his plans and pro- ceedings, the adventurers encounter not a few perils. The intro- duction of a very remarkable man, who went through some strange experiences, and who is still an unsolved problem, gives to this book a special interest.
