October -H 1911. 
Dear Professor Pittier: 
I bog to acknowledge the rocoipt of your com¬ 
munication of October 2d, enclosing your accounts for 
the months of July, August and September. Shoso have 
been examined by the Disbursing Officer, who reports 
that they are corroct, with the following exceptions: 
Shore is no indication in the statement as to 
what Sub-vouchor Ho. 17 is for, as the numbers go from 
Ho. 16 to Ho. 18. 
Sub-voucher 19 is noted in tho statement as 
"Aug. 25, Haros and freight to ?t. Obaldia, "23.50", 
but the sub-vouchor itself is missing. 
Sub-vouoher Ho. 30: "Aug. 25, Hotel Booh, 
$15.00", is at hand, but tho amount was omitted from 
the statement, so that instead of being credited with 
$526.77, you are in fact to be credited with $541.77.
