I have thought it proper, in this my personal nar- 
rative, to relate briefly the principal events which con- 
stituted the main objects of the Commission, and, in

establishment of the initial point on the Rio Grande 
and the southern boundary of New Mexico. In so 
doing I have spoken merely of the mode of determin- 
ing this boundary, without, in any manner, going into 
the argument as to its conformity with the treaty. My 
readers can be the judges of this. My defence of the 
point and line established, with the argument of Mr. 
Gray in opposition to them, was presented to the Hon. 
Alexander H. H. Stuart, Secretary of the Interior, on 
the 7th of February, 1853, on my return from the Sur- 
vey, and ordered by the Senate to be printed. This 
forms Senate Executive Document No. 41. 3 2d Con- 
gress, 2d Session. 
After the establishment of this important point, I 
immediately made known the particulars connected 
with it to the Honorable Secretary of the Interior.
