erally of a sandy color, which makes them hardly dis- 

 tinguishable from their desert surroundings. The large 

 ones are swift strong runners, like the antelope and 



ostrich, or, like the 

 camel, are able to travel 

 for long distances with- 

 out water. 



In the colder regions 

 the plants have the 

 power of rapid growth 

 and germination during 

 the short season when 

 the snow has melted 

 away. Then, during 

 the long winter, they 

 lie dormant but un- 

 harmed under the snow 

 and ice. The animals 

 are either able, like the 

 reindeer, to live upon 

 the dry mosses, lichen 

 and stunted bushes, or 

 else upon other ani- 

 mals. Their color, like 

 that of the polar bear, 

 often blends with their 

 surroundings. 



Some animals have a 

 wide range of adapta- 

 bility, like the tiger, 

 which is found from 

 the equator -to Siberia.* 

 But usually the range 

 of an animal species is 



TIGER. 



One of the most widely distributed of 

 animals.
