laterals should be dug out and burnt as old rubber butts have 

 proved one of the most fruitful sources of UstuUna sonata and 

 other fungus gi'owths. 



My suggestions are based on the supposition that directors have 

 in view an average yield of say 450 lbs. diy per acre. Possibly 

 they may hope for 500 lbs., but it must be remembered that with, 

 say, 50 ti-ees per acre this would mean an average yield of 10 lbs. per 

 tree. The highest yield which 1 have records of for a section of 

 over 100 acres is 8.33 lbs. per tree for a section of 110 acres of 13 to 14- 

 year old rubber This is still some way from the legend ascribed to 

 a well-known planter of a single ti'ee per acre connected with the 

 factory by a pipe.
