INCIDENTS AT THE 
we hastened to get our wagons, mules, tents, camp 
equipage, provisions, etc., ready in order to take the 
field as soon as possible. 
While these arrangements were in progress, I sent 
a messenger to Santa Fe, with a letter to Colonel Sum- 
ner, commanding the troops in- that military division, 
with a request that another company might be fur- 
nished me for an additional escort. This, on consul- 
tation with the army ofiicers, was deemed actually 
necessary. Our present escort had been greatly 
reduced by desertions and sickness, so that there were 
less than forty effective men. We were now about to 
enter into the particulars of the serious difficulties which took place 
between the Principal Astronomer, Colonel Graham, and myself, imme- 
diately on his arrival, growing out of his extraordinary and inexcusable 
delay of more than nine months from his appointment, in reaching tire 
field of operations, and of his assumption afterwards. Never, in the 
whole course of my life, have I been placed in so trying a position. But 
such were my instructions, and such my responsibilities as head of the 
Commission, that I must either maintain this position, or, in succumbing 
to the demands of Colonel Graham, make myself and the Chief Surveyor, 
Mr. Gray, subordinate to him, resign all power and control on the mem- 
bers of the Commission, and become a mere nullity. I preferred 
the former alternative; and in order to lay the matter before the 
Government, and abide its approval or disapproval, I sent Mr. Charles 
Radziminski, the Principal Assistant Engineer, to Washington with my 
dispatches. These unfortunate difiBculties with Colonel Graham, most 
of which was owing to contention for rank and position between Mr. 
Gray and himself, greatly retarded the progress of the Survey, and caused 
much suffering to the parties engaged on the Gila portion of the work. 
The Government sustained me in my position, and removed Colonel 
Graham, appointing Major W. H. Emory in his place. The Correspon- 
dence on this subject maybe found in Senate Document No. 119, 32d 
Congress, 1st Session — and particularly in my Dispatch to the Hon. Sec- 
retary of the Interior, No. 21, page 433 of the same document.
