was t lis* t the (license had possibly been introduced into Mysore from 

 South America. Of late years little has been heard of the disease in 

 cither hemispheres. It was at no period so virulent in its character as 

 the well-known coffee-leaf disease of Ceylon {/fe/tii/cia rasfatrir), and 

 with ordinary care on the part of cultivation it was not anticipated it 

 would become a formidable enemy to coffee cultivation. Interest in 

 this disease has now been revived, as it has been found by Mr. T. D. A. 

 Cockerell on coffee in Jamaica, where, however, it was suspected to have 

 existed for some time. Reference is evidently made to it in the follow- 

 ing words, which appeared in the Kew Report, 1876, p. 20: — " A some- 

 " what similar <li-ea-<- to the /', llicnlnriu. but described in too vasrue a 

 " manner to speak definitely upon, seems to have occurred in 1864 in 

 " Jamaica, the leaves of the coffee plants being covered 'with a white 

 " substance of a gelatinous nature.'" Further, in the Kew Report, 1877, 

 p. 27, it is stated, after showing the identity of the " Koleroga " of 

 Mysore with the " Caudelillo of Venezuela, that " it is possible that the 

 "disease which I mentioned last yar as having occurred in Jamaica 

 "may also be identical with the ' Caudelillo. '" In forwarding a specimen 

 to Kew Mr. Cockerell state- that the diseased leaves were found on 

 an estate in the neighbourhood of Mandeville. The disease was quite 

 local in its character though abundant in one spot. As it is external 

 in its habit it is needless to add that it may be oasilv treated in the early 

 stages with powdered lime and sulphur. The fallen leaves should be 

 carefully gathered and burnt at regular intervals. The latter treatment 

 is probably the more convenient to the planter, and if carried out with 

 cai-e and regularity it might be sufficient to keep the disease from 

 spreading to ether plantations. The coffee industry in Jamaica, is eon- 

 fined to two comparatively small areas, one in the "parish of Manchester 

 at an elevation of 1,500 ft. to 2,500 ft., and another in the Blue 

 Mountains at elevations up to 6,000 ft. The best qualities of Jamaica 

 coffee (for which the highest juices reach l.'io.*. to 1 I2.v. per cwt.) are 

 entirely produced in the Blue Mountains district. The occurrence of 

 the present disease in Jamaica coffee suggests that careful steps should 

 be taken to prevent it from spreading and that cultivators should be 

 keenly alive to notice the existence of any disease on their coffee trees, 

 in order that prompt and decisive action may be taken to prevent serious 

 injury.
