hulls of the breaking-ground, and sometimes spreads to 

 the beans, which it completely destroys. All diseased 

 fruits, the old husks, and also the prunings should be 

 burned or buried in order to prevent the spread of the 

 disease. 



The disease is now known in Jamaica, St. Lucia, 

 Vincent, Martinique, Granada, Trinidad, Barbadoes, 

 St. Thome, Ecuador, San Domingo, Brazil, West Africa, 

 Cameroons, French Congo, East Federated Malay States, 

 East Indies, Ceylon, Java, and the Philippines. It also 

 attacks the Para rubber, mango, papaw, tea, sugar-cane, 

 and many other tropical plants. 



In Trinidad it is said to be associated with Nectria 

 theobromae, Massee, and this may also be true in other 

 places. A similar disease is said to occur in Brazil, 

 but may prove to be identical. This disease should not 

 be confused with the rusty or mahogany colour of the 

 fruits, which is said to be due to thrip injuries, but 

 which does not penetrate beyond the rind. 



Dieback. This disease is due to the same fungus 

 as the brown rot. It causes the young twigs, and 

 frequently the larger branches, to die in both directions 

 from the point of infection. The first evidence of the 

 disease is in the dying of the tip, but the disease con- 

 tinues to work backward, and may eventually reach the 

 trunk. The progress of the disease on the trunk is 

 accompanied by the death of other branches due to the 

 interference of the fungus with the conduction of water. 

 New shoots are put out back of the disease, and in case 

 the disease is checked by natural or other causes one of 

 these shoots may produce a branch. Although infection 

 usually occurs in the branches, the trunk and lateral 

 roots may also serve as points of infection. When 

 several of the top branches are infected the disease is 

 frequently spoken of as " stag head," but this condition 

 may be due to other causes. The progress of the disease 

 depends upon the general health of the trees and the 

 care to which they have been subjected. When the 

 progress is slow cankers are frequently formed. In
