THE "KEN WARD" STORIES

The Young Forester
Kenneth Ward, a young eastern lad just out of preparatory school, goes west on his summer vacation to join a friend, Dick Leslie, a government forest ranger in Arizona. Ken, honest, loyal but hot-headed runs into plenty of excitement and trouble when he finds that a big lumber steal is going on.
The Young Lion Hunter
Ken Ward and his kid brother, Hal, spend a summer on a forest preserve in Utah with Ken's pal Dick Leslie. The government rangers are out after the mountain lions and the boys from the east are glad to share in the thrilling work. 		The Young Pitcher
When Ken Ward entered Wayne College to pursue his study of forestry he discovered that as a freshman he was on the bottom rung and had to fight to win his way to recognition. His first claim to fame comes when he pummels a prominent sophomore in self-defense.
Ken Ward in the Jungle
Ken Ward and his younger brother Hal take a trip into the wilds of Mexico—Ken to try his hand at field work in the jungle and Hal, who is ambitious to become a naturalist, to collect specimens. The boys set out to solve the mysteries of the Santa Rosa River, an unknown course of about a hundred and seventy-five miles through uncharted jungle.
STORIES OF BASEBALL
Zane Grey's baseball is as real, as dramatic and as thrilling as the western stories that made him famous.
The Redheaded Outfield
The Redheaded Outfield—three fiery-pated players who introduce a little boxing and plenty of comedy into the game will delight you. The Rube—who is all that a rube should be—appears in a whole series of these stories and is a character you won't forget.
The Short-Stop
Chase Alloway developed a mean curve that had the small town players buffaloed. They called him "Chaseaway", the "Hoodoo" and "crooked eye" and one small town team was all for having him tarred and feathered! A story crowded with hard and fast baseball—and a dash of romance!
STORIES OF THE GREAT WEST
The Last of the Plainsmen
"He'd rope the devil and tie him down—if the lasso 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 passion 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. 		The Last of the Great Scouts
The life story of "Buffalo Bill" by
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.
