STORIES OF BASEBALL

The Redheaded Outfield

STORIES OF THE GREAT WEST

The Last of the Plainsmen

"He'd rope the devil and tie him down--if the la.s.so didn't burn," it was said of "Buffalo Jones," one of the last of the famous plainsmen who trod the trails of the old West. Killing was repulsive to him and the pa.s.sion of his life was to capture wild beasts alive.

A real hunting trip--with constant danger threatening from wild beasts, Indians and the hazards of wild country untouched by civilization.

Roping Lions in the Grand Canyon

A true story of Zane Grey's experiences capturing lions alive, which makes ordinary hunting with guns seem, in contrast about as exciting as a Sunday-school picnic. The account of how they captured six of the tawny, fiery-eyed demons which infest the bottom of the Grand Canyon, and got them into camp alive and growling, will enthrall the great host of Zane Grey's boy readers.

HELEN CODY WETMORE

_With Foreword and Conclusion by Zane Grey_.

"Buffalo Bill"--scout, pathfinder, hunter and Indian fighter is the most famous of all that great company of frontiersmen who opened up the West for civilization. Indeed no character in history makes a stronger appeal to the imagination than this daring hero of the old west.
