from the dustjacket:
LONG long ago, in what we now call prehistoric days, Britain was inhabited by various tribes of people who were quite unlike one another and who lived in very different ways. Little Ruadha, or Red Head, for instance, was the daughter of a very fine fisherman, who became chief of the River People. And Yeru was the son of a head man among the Flint People, who lived in hut-circles on the hillsides, and his mother, Tua, came from the Tree People. Then there were the Ploughing People, the Shepherd People, the Marsh People, the Cave People, and the Horse People. All these tribes came to trade at the Stone of Covenant, and gradually grew to know and understand each other.
This book is about the children of these various strange tribes. They had to know about things of which boys and girls of to-day never need to learn and their whole lives were full of excitement and adventures, often of the most dangerous sort. They were what we should call wild, but they were quick of sight and keen of hearing; they moved as swiftly and as silently as shadows, and they were very strong and brave. They had their work and their play, and children of to-day cannot fail to enjoy these stories about them and the Britain where they lived.
