Conclusions. 



1. Jamaica must be divided up into districts and each considered as 

 an agricultural entity on its merits. 



2. There are large areas of land in Jamaica upon which sugar cane 

 can be cultivated successfully, and which are not at present in ade- 

 quate cultivation. 



3. Sugar cane cultivation has survived on some 120 estates owing 

 to the extraordinary fertility of the soils and the natural advantages 

 of certain districts for sugar production. 



4. The sugar-cane is successfully grown in Jamaica on soils varying 

 from light, gravelly sands to stiff clays ; on soils consisting of 50 per 

 cent of chalk, as well as on lands in which this ingredient is almost 

 absent. 



5. Irrigation and climatic conditions affect the results obtained to 

 an extraordinary degree. An increase of the irrigable area under su- 

 gar cane is higly desirable. 



6. All the sugar soils herein reported on, upon which the cultiva- 

 tion is normally successful, present on the whole a very high 

 standard of fertility. The proportion of phosphoric acid is particu-
