been commenced by Colonel Graham, at the Initial 
Point, and prosecuted as far as the Paso del Norte, and 
an observatory partially erected at Frontera, and infor- 
mation given me by Colonel Graham that Frontera, 
a cardinal point in the survey, had not yet been deter- 
mined. J also found it necessary to resurvey the river 
down to Frontera.” * 
Deducting, therefore, the re-survey which Major

hham’s arrival, another survey was made under his imraediate direction, 
and afterwards rejected by his successor Major Emory. The latter 
placed the work in the hands of Mr. Radziminski, Principal Assistant 
Surveyor, by whom it was execuied in a highly satisfactory manner, and 
mocopted as the official Survey.
