THE HISTORY OF LIFE 203 



table life still more approaches modern life forms. 

 The climate appears to have been similar to the climate 

 of to-day. The horse and ass have only one toe, as 

 they at present appear. The ox, cat, bear, fox, beaver 

 and mouse and other living animals existed in these 

 times. 



The Pliocene rocks are found in Britain, Belgium 

 and Holland, France, Italy, Germany, Greece, North 

 America, Australia, and New Zealand. 



Lying on the above and subsequently deposited are 

 found the rocks called by geologists the Post-Tertiary 

 or the Quaternary rocks. And here commences the 



FOURTH BOOK OF THE GREAT STONE BIBLE. 



At first the temperate parts of the northern 

 hemisphere became glacial, a condition similar to the 

 North Pole regions. The whole of Northern Europe 

 was buried under ice far south ; and, beyond the edge 

 of this huge sheet, every highland became a centre for 

 glaciers which spread far over the lowlands. This 

 occurred even in the heart of France, and the temperate 

 forms of life were destroyed or driven towards Africa. 

 It is estimated that the area of Europe thus buried in 

 ice was not less than 770,000 square miles. In some 

 parts the earth may have been buried beneath ice 6000 

 to 7000 feet thick. The same Ice age existed in North 

 America. The boulder clay formed during this epoch 

 has given rise to vast deposits. It is believed by 

 some that there were five distinct glacial epochs 

 between which temperate climate intervened. All 

 this information tends to the view that the earth's 

 axis has altered from time to time, so that some new 

 portion of the earth occupied the Arctic region, and
