2. I understand that the cotton worm occurs in Jamaica, but am 

 not informed as to the seriouness of its attack, nor as to its distri- 

 bution in different parts of the island. Also the Cotton Stainer, 

 Dysdercus andreae, is reported to occur in Jamaica, but very little 

 information seems to have reached this Department as to its pre- 

 valence. 



3. It would be interesting to learn whether the Leaf-blister mite 

 is known in Jamaica ; if not, great efforts should be made to keep 

 this out of the island. 



4. With regard to fungoid diseases, the only one recorded here 

 from Jamaica is the leaf-spot caused by Cercospora gossypina. I 

 should be glad to learn if any of the following diseases occur in 

 Jamaica : — leaf mildew, leaf rust {Uredo gossypii), anthracnose 

 {Colletotrichiwt gossypii), or black boll (a bacterial disease). These 

 are some of the diseases known to occur in other West Indian 

 Islands. 



5. I should also be glad to know if you have any cotton diseases 

 which so far have not been recorded from the other islands. These 

 are described in the •' West Indian Bulletin," the " Agricultural 

 News," and the " A. B. C. of Cotton Planting," issued by this De- 

 partment. 



6. I would add that it would be useful if members of your So- 

 ciety or Board could supply specimens of these diseases and pests 

 for study and information regarding them for the use of Cotton 

 growers generally in these Colonies.* 



I have the honour to be, 

 Sir, 

 Your most obedient servant, 



D. MORRIS, 

 Commissioner of Agriculture for 

 the West Indies.
