My dear Wetmore: 
I am forjvarding herewith a letter which in a way explains 
itself. It appears that Mr. tiartin is interested in a large 
citrus fruit plantation and that the oranges particularly suf- 
fer from the attack of a beetle. I do not know v/here this plan 
tation is in relation to your present whereabouts, but would 
urge upon you the importance, v/hen practicable, of investigatin 
the matter here mentioned. It is iii^ortant, of course, to know 
just what beetle he refers to, and you will no doubt find on 
this place every facility for your work as su^ested by him. 
Very truly yours, 
LL Chief, Biological Survey. 
N.B.I do not mean that you necessarily confine your investiga- 
tion of the citrus fruiL pest to this particular plantation, as 
it may be more convenient to invcsti^ue it elsewhere. Indeed, 
you may already have collected birds in citrus fruit orchards 
and may even know something of the green beetle he alludes to 
as so destructive.
