As these can easily be made locally, I would suggest that the sec- 
retaries of the planters’ associations concerned should have them ready 
beforehand (by 15th March), with the necessary wire for affixing. 
The same number of bushes will also have to be selected in readiness 
beforehand and I would suggest that the secretaries or experimenters 
should have this done also by the same date. 
(vii) Observations of insects visiting coffee-flowers. 
“The experiments may usefully be supplemented by direct ob- 
servation of the insects actually visiting the coffee bushes whilst these 
are in bloom. ee 
I propose, that in each district, a representative collection of these 
tsects shall be made and as, for this to be done properly, continuous 
observation and collection from early morning until after dusk will be 
necessary, this work will take up one man’s whole time. For this 
therefore, I propose to send a member of my staff to each district ; but 
if this is done, arrangements will have to be made for their »ccommo- 
dation. They would of course provide for their own food. The men, 
I have available, are two assistants and two fieldmen. The assistants 
are Brahmins and University Graduates; the fieldmen are both Native 
Christians. I shall be glad to know whether districts have any 
particular preference for either class of men. 
Should I myself be free to visit Coorg (as proposed above) I shall 
propose to give my time chiefly to observation work of this kind, as a 
supplementary worker.”
