122 JUNGLE ISLAND 



light enough on the forest floor for a good picture. 

 The photograph given (Fig. 52) is the best of a 

 poor lot. 



In the pool were several fish, eight inches long 

 or less, on which I suspect he depended for food. 



The caimans are related to our Florida alli- 

 gators. Like the alligators, they lay their eggs 

 in heaps of rotting leaves and twigs, which serve 

 to keep the eggs moist and at about the same 

 temperature. Crocodiles bury their eggs in the 

 ground. Caimans are found as far north as 

 southern Mexico, and they spread far into South 

 America, where they live in great numbers along 

 warm, quiet rivers and swamps of the rainy 

 tropics.
