The animals share the same fate as the plants. Domes- 

 tic animals replace the wild denizens of the country. 

 Only in inaccessible and waste places are a few lone rem- 

 nants of the native fauna left. If the area which man 

 enters is limited and bounded by impassable barriers, as in 

 the case of islands, certain animals may be entirely exter- 

 minated, as wolves and bears have been in England. If 

 the animal is a unique species, its extermination from its 

 native island may mean its total destruction, as in the 

 case of the dodo of Mauritius.

 extensive areas where the growth of forests had been 

 checked by fires set by the Indians. The prairie regions 

 were probably much enlarged by the annual grass fires.
