THE SUGAR CANE SOILS OF JAMAICA.-III.* 



By H. H. Cousins, Island Chemist. 



THE UPPER VERE PLAIN. 



A series of twelve samples of soil from the chief lands of Den- 

 bigh Estate has been analysed and after careful comparison with the 

 results from other soils and a consideration of the indications of 

 manurial experiments, advice as to the practical treatment of each 

 soil has been given. It will be noticed that every soil in the 

 series is deficient in carbonate of lime and in some cases it was 

 not possible to detect any carbonates at all. 



I have arranged with G. W. Muirhead, Esq., that an acre of land 

 on each piece shall be treated as recommended, so as to test the 

 practical utility of advice based upon analytical and experimental 

 data. The analytical work has been performed by Mr. H. S. 

 Hammond, F.C.S., and the mechanical analyses are mainly the 

 work of Mr. T. H. Sharp, Jr., B.S.A.
