Observations. 



This soil will become lighterwithcultivation. The high amount of 

 fine silt is remarkable, making this soil a heavy one as first turned 

 up. The constants of fertility are normal. The humus is not very 

 high and might be increased to advantage. Lime is also needed ; 

 otherwise this soil presents all the factors for excellent cane land. 

 I recommend a ton of lime per acre and systematic use of green 

 dressings. I do not advise chemical manures for this soil. 



TOBACCO OF JAMAICA, III.* 



JAMAICA SHADE-GROWN TOBACCO FROM SUMATRA SEED. 



By WM. M. Cunningham, Assistant Superintendent and Agri- 

 cultural Instructor, Hope Experiment Station. 



The experiment in the growing and curing of wrapper tobacco 

 from Sumatra seed under shade cloth at the Hope Experiment 

 Station, has been successfully carried out. The texture and the 

 elasticity of the leaf are all that can be desired, while the colour 

 is perfect. 



The cigar manufacturers who have examined the leaf pronounce 

 it of a high quality, and the colour equal to that imported from
