"This title, illustrated in realistic, appealing oil paintings and spare, well-paced prose, conveys a sense of the Old West—not the rush for riches but the open trail and the warm details of daily activity. ...[C]hildren will eagerly follow Dorsey as he travels the trails alone, with mailbags buckled onto his furry back."
