THE CHORUS OF MAN’S STAGE 
To whichever species the Java fossil remains may be as- 
signed, the next period, the Pleistocene, indubitably brings 
in the dawn of the day of man. His advent 1s demon-

Fic. 1. Woolly rhinoceros of the Pleistocene in Europe. A mural drawing in 
red in the cavern of Font-de-Gaume, Dordogne, France. After Capitan, Breuil, 
and Peyrony 
Pleistocene animals is proved by his drawings of spirited 
likenesses of some of these creatures in the caves of south- 
ern Europe, as well as by the association in European 
fossil beds of primitive human skeletons and artifacts with 
bones of the mammoth, the woolly rhinoceros, and other 
animals now extinct. The Pleistocene, or Glacial period, 
was remarkable for the several advances and retreats of 
arctic and antarctic glaciation. In North America the ice 
sheets pushed as far south as the junction of the Ohio and 
Mississippi rivers, while in Europe ice sheets invaded the 
plains of France. Thus in the infancy of the race, man 
struggled against odds. 
Beginning with the dawn of life, we have surveyed 
animal and vegetable development through the early 
Paleozoic, the age of the invertebrates; the Devonian, the 
age of fishes and of the rise of vertebrates; the Carbonifer- 
ous, or heroic age of vegetation; the Triassic, Jurassic, and 
Cretaceous, embracing the long dominance of the giant
