Dear Ur. 'Jetmore 
I am enclosing a letter which will authorize you to proceed 
to Idaho whenever conditions seem to he most favorable for the 
investigation. 
I hope that your work: is progressing satisfactorily. It 
will he of interest to find out whether very low water will in- 
crease or diminish the trouble among the waterfowl. Col. O’ Conor 
is very anxious tc secure the pintails, and I hope that before the 
season is over you will be able to furnish him with ten or more 
pairs. lie does not wish the birds pinioned but merely the primaries 
of one wing trimmed. 
1 am also enclosing a Form 4 voucher resubmitting your ex- 
pense account from Denver to Ft. Collins last November, so as to re- 
imburse you for this trip. You do not have to swear to the account.

It was originally submitted under the wrong letter, as stated in a 
recent letter from the business office* The only loss which you 
will iiKrur will be for extra fare due to stopping at Ilahhattan#
