Miss Lucass was co-author with W. Maxwell Reed in Animals on the March. This lively new book in the field of science for younger readers, traces the history of man, as revealed through excavation and discoveries, and the study of fossils and bones. The record goes back to the ape man of Java, then the Pekin man and the Piltdown man. Clues to his way of life through the implements and weapons he used. Then, almost to modern times, with the Neandertal man, the first indications of social organization; the invaders, Grimaldi and Cro-Magnon and the art records on the caves. Finally, with the retreat of the glaciers, the world began to change and man with it. Where the other book followed the evolution of animals, this follows the human race.
