Cowboy Small takes good care of his horse, Cactus. In return, Cactus helps Cowboy Small get work done on the range. Together they round up cattle for branding and live the good life. At night, Cowboy Small eats at the chuck wagon, sings with his friends, and sleeps under the stars.

In a new board book edition of the delightful story, Engineer Small at the throttle takes the little train on its run from Tiny Town to the big city.
