The first traces of man appear in the later geologic times 

 after the end of the Tertiary. Human bones have been found 

 in caves together with those of the cave-lion, cave-bear, and 

 other extinct animals. In certain lakes in Switzerland and 

 Austria have been found remains of peculiar dwellings, to- 

 gether with ancient fishing hooks and a variety of imple- 

 ments of stone and bronze. These houses were built on piles 

 in the lakes, and connected with the shore by piers or bridges. 

 The extinct race of men who lived in them is known as 

 Lake-dwellers. Relics of man, especially rough stone tools 

 and flint arrow and axe heads, and skulls and other bones,

have been found under circumstances which indicate with 

 certainty that man has existed long on the earth. But with 

 these relics very few bones are found. This has been ac- 

 counted for by supposing that man existed in a few wander- 

 ing tribes scattered widely over Europe. In Java are found 

 some ancient bones of manlike animals (Pithecanthropus), dif- 

 ferent, however, from any species or race of men living to-day, 

 and showing traits which indicate a close relationship with the 

 anthropoid apes. 



The time of historic man i. e., the period which has elapsed 

 since the history of man can be traced from carvings or buildings 

 or writings made by himself is short indeed compared with 

 that of prehistoric man. Barbarous man writes no history 

 and leaves no record save his tools and his bones. Iron and 

 bronze rust, bones decay, wood disappears. Only stone im-
