It was May, in the heart of the Idaho prairie and Joss Melbourne was intent upon raising five hundred precious dollars for his father's operation. Many ideas cross his mind, the most likely of which is to sell his father's hog herd. But Dad won't hear of it. Like a gift from Heaven, a herd of wild hogs appear in a canyon and Joss and his cousin Sterling decide to drive them to Prairie Town themselves. The trip is most eventful, strewn with such obstacles as complicated river crossings, a minimum of water and some ornery animals. But what saves the day and in the end brings home the bacon is Sterling's courageous feat in roping a wild hog before a critical audience in Prairie Town. Joss' adventures with his dog run a parallel plot. This is a colorful and picturesque tableau of droving in the old West as well as an example of man's dependence on animals as a source of livelihood.
