284 DOMESTICATED ANIMALS AND PLANTS 



wide-ranging races that may be, and likely are, subjected to 

 cultivation at very many independent centers. 



Added to these are many undeveloped possibilities in unculti- 

 vated fruits, like the huckleberry and the cranberry, which latter 

 is coming into semidomestication in order to furnish the demand 

 that goes with the Thanksgiving turkey. 



The tropics afford an almost endless variety of fruits, some of 

 them only just rescued from the wild. The forests and jungles 

 of such formative regions as the Amazon valley abound in fruits 

 as well' as nuts in the greatest profusion and of the greatest 

 variety. The world is being ransacked now for new and valuable 

 varieties, either cultivated or wild, and very much of the work 

 of domestication of plants is still going on even in our own day, 

 though it is a question whether a new animal will ever be added 

 by domestication. It looks rather as if in respect to animals we 

 should be restricted in our possessions to what we can achieve 

 out of the materials already in hand.
