The percentages of moisture recorded above are probably much 

 lower than the amounts actually presented in the balls, as the paper 

 in which the samples were wrapped had evidently absorbed a 

 considerable amount of liquid during transit. You will observe that 

 the percentage of resin is a little high in both specimens and that the 

 amount of proteid in No. I is greater than usual in plantation rubber, 



I shall be interested to learn the results of the sale of this small 

 consignment of rubber.

Sir, — In further reply to your letter of 2ist April, headed 

 "Economic" 035/09, and acknowledged on the 20th ult., I have now 

 received from our Works an analysis and report on the two samples 

 of rubber which you submitted. When I examined the samples I 

 formed an opinion of them which has been borne out by our Works' 

 report. They had an appearance which did not do them justice, 

 but even making allowance for this you will see that they are not 

 considered equal to Fine Para by 8 to 157,. Of the two, No. 2 is 

 the weaker and softer, which may be due to the latex being collected 

 from younger trees, because it seems strange that while the No. I 

 is undoubtedly overheated in the process of smoking, yet it is 

 superior to the No. 2 sample.
