Each Volume Complete in Itself. Thrilling tales of the great west, told primarily for boys but which will be read by all who love mystery, rapid action, and adventures in the great open spaces. The Manly boys, Roy and Teddy, are the sons of an old fanchman, 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.
