Set in the silver-mining camps of California's Mojave Desert in 1885, this is the semi-factual story of Dorsey, a remarkable Border collie who carried the United States mail between Bismarck and Calico. Apparently, after following the mail burro between the towns the former stray knew the route; here, the postmaster's daughter Nellie acts as the initial motivation for the lonely dog to make the trek. Border collies are famous for their work ethic, and as a mail dog he conscientiously and expeditiously carried letters and small packages to the miners. Readers should enjoy—and be enlightened by—this delightful sidebar to California history. Gustavson's illustrations in oil convey topography, characters, settings and a fine canine. They are active and charming, and Dorsey leaps off the page, tail wagging, just waiting for pats, company and biscuits. One jarring note: All the miners and their clothing seem very clean considering their trade and the scarcity of water in the desert. An author's note provides a photo of Dorsey with his mail pouches and good historical information, including the fact that Nellie is fictional. (Picture book. 4-8)
