144 ANOTHER VISIT TO THE ANDAMANS 



been turned loose there, and have already become 

 feral. There is on the island a sufficiency of coarse 

 grass, bamboo, and fresh water for the support of a 

 small herd of them. What will these cattle become 

 like? 



The next relates to the domestic (pariah) dogs 

 which have become wild there. For them there is 

 plenty of miscellaneous feeding on the reefs and in 

 the jungle, and so they should not die out. But what 

 modifications will they undergo ? 



The third inquiry is connected with the fauna of 

 the freshwater lake on Little Coco. There is abun- 

 dant evidence that this lake was, not very long ago, 

 a mangrove creek in open connection with the sea, 

 and there is no evidence that man had anything 

 whatever to do with its conversion. There is no 

 other fresh water on the islet, so that here we seem 

 to have a perfectly clear sheet upon which to record 

 the manner of colonisation of a freshwater territory 

 newly won from the sea.
