The story of Charles Goodnight's lead steer ... Old Blue
Sibyl Hancock. 1980. The child's version of the story about Charles Goodnight's legendary lead longhorn - Old Blue. It might be classed as historical fiction, but Old Blue was a real longhorn, and the stories (this is only one of them) as to how he kept Goodnight's cattle drives as close to orderly as a cattle drive can be. are just fun reading (used copies)
Good for most all ages;
