not possible definitely to interpret the areas in which certain crops may 

 be produced, yet it is possible to point out that information obtained by 

 study and experience in either zone is applicable to other portions of the 

 same zone and in this way interjjret the region of most probable success 

 in new districts. 



The aims of agricultui-e in all parts of the Archipelago are practically 

 the same, but there are many differences iu crops and in agricultural 

 practices. Perhaps these should be essentially different in the two rain 

 zones, but in general in the same zone the best crops grown and the best 

 methods used by any province should be extended to every other district 

 possessing the same soil characteristics. 



It is an established fact that alterations of wet and dry periods often 

 will show correspondingly marked differences in vegetation and fre- 

 quently, if not always, the prevalence of any particular t^^pe is directly

This theory is remarkably substantiated by Table Til which shows

 of rainfall.
