The third in the series on prehistoric man, and perhaps the most interesting, in that it deals with that phase of development in which the taming of beasts began to be accepted as something not wholly strange and unnatural. A story of two youths, one a hunter, the other eager to capture and tame the wild dogs and oxen he encountered. An accident thrusts them for months into another group, farther advanced in civilization -- interesting evidence of the way levels of civilization were interchanged. These books, beginning with In The Stone Age, fill a definite need in supplementary reading, and are ""musts"" for libraries and school libraries. Should have some bookstore appeal, for fiction and adventure with good factual background.
