from its conspicuous whitish color, and easily dealt with by destroy 
to? infected branches, and in the case of the trunk being affected by 
scraping it off and treating with copper sulphate and lime. 
Hitherto there has been no record of it in the Peninsula but Mr. 
R BURGESS sends a stick covered with it from Sunge p 
Perak He writes that he has seen a few trees suffering from it on 
Plang Estate. It attacks the upper branches of the tree which die if 
not attended to. The Manager, Mr. Philips says that a mixture of 
I ime and. Copper sulphate appears to kill the growth of the fungu. 
antT many trees have been saved thereby. It is by no means wide 
spread appearing only occasionally on a few trees, and no seriou 
damage Is done fany branches found to be affected are immediately 
cut off and burned. The tree from which the specimen was taken 
is about 3 years old, planted ten by ten on the side of a hill with 
coffee interplanted at the same distance looking perfectly health, 
and showing excellent growth. 
The close planting in this ca® confirms my suggestion made 
previously that this is really the cause of the development of the 
plant a somewhat similar pest occurring on bushes of Strobilanthes 
and Ramie in wet weather chiefly when overcrowded and is another 
reason for planting further apart if any additional reason were 
wanted. The treatment adopted by Mr. BURGESS is the best pos- 
sible under the circumstances and by means of this system it shou d 
not be difficult to prevent this fungus from becoming seriously 
injurious, but planters must of course keep an eye on any appearance 
of the plant and treat it promptly. In tall trees it may be difficult
