The day after arriving for their third summer on the Five Bard Ranch, twelve-year-old Kip and thirteen-year-old Scootie ride out with Uncle Bill to round up horses. They find the bunch they want, but three renegade horses stir up trouble and lead Uncle Bill on a wild chase. Kip and Scootie try to keep up through the rough hills but end up lost and on foot. Over the next few days, they learn plenty about resourcefulness and self-reliance for, as Uncle Bill says, Old Mother Nature and necessity sure don't stinge on education. Join Kip, Scootie, and Uncle Bill for some wild adventures as they follow each other's tracks and find -- among other things -- the three renegade horses.In the Saddle with Uncle Bill is Will James's second book with Kip, Scootie, and the wily cowboy, and the fourteenth title in the Tumbleweed series. James's illustrations of these memorable characters capture the energy and excitement of life in the wide open West.
