Chip of the Flying U

"In Chip of the Flying U, James G. Whitmore's sister Della, who just became a doctor, is coming to stay for the summer. She causes a lot of uproar among Chip and the rough and tumble cowhands who work on the range in the badlands at the edge of the Rocky Mountains. All of the boys at the Flying U did a lot of grumbling among themselves. They didn't want a woman at the ranch! But if they -- particularly Chip -- could have had an inkling of what was really going to happen, they would have done more than grumble."--
