The Manly Boys, Roy and Teddy, are the sons of an old ranchman, the owner of many thousands of heads of cattle. The lads know how to ride, how to shoot, and how to take care of themselves under any and all circumstances.

The cowboys of the X Bar X Ranch are real cowboys, on the job when required but full of fun and daring—a bunch any reader will be delighted to know.
