The story of a boy shepherd who drives a huge herd across miles and miles of mountains, deserts and rough land with a wise and experienced herder as guide. It is an unusual and interesting study of the habits and peculiarities of flock psychology, of animal behavior. There's suspense and excitement too, for the flock is attacked by wolves, snow storms and other dangers and Toby's talks with the old shepherd and his decision to reach the Valley by the deadline blend well with the huge outdoor feeling of the Arizona country, the monotonous, slow movement and great responsibility of guarding two thousand sheep through Heber Sheep Pass. There isn't a great deal of plot, but Toby is a nice boy with a big job and readers will be curious how each new problem will be solved. It is a fine picture of life and activity that children are apt to know little about. Large type.
