The book was donated to a library but checked out only 10 times.  The dust jacket is price clipped and in pristine condition as is the book itself.  

A fast-paced sequel to OLD YELLER and SAVAGE SAM.  Now 12 years old, Arliss is sick and tired of being told that he's too little to do grown-up things.  His father is trying to catch an outlaw horse, Salty.  So Arliss sets out to prove he can catch the horse by himself.
