ORNAMENTAL PALMS 239

 marketable fruit, and study of the palm that has 

 been undertaken in this connection will doubt- 

 less lead to important results. Even now it has 

 been demonstrated that just as good dates can 

 be grown here as in the Sahara. 



It appears that the palm, notwithstanding its 

 relative fixity, is subject to considerable vari- 

 ation, and that this is particularly true of the 

 date palm fruit, as might be expected consider- 

 ing that this tree has been under cultivation from 

 prehistoric periods, and because it has been 

 selected for the fruit alone. 



The most delicate and delicious date fruits are 

 not the ones that can be secured for export, so

 American market until they are grown here. All 

 the best date palms, unlike most other palms, are 

 grown from suckers which come up from about 

 the roots of the tree. 



To be sure, the Oriental peoples, for whom

 Still the broad general fact that "like produces

 from remotest antiquity, and it can hardly be
