a two-rod surveyor’s Chain, which was carefully tested before and 
after the measurements, For a base line I selected a portion of 
the road-bed, 2255-66 feet long, in that portion of the town known 
we * Andover Plain.” The westers end of the base was 11°55 
south of, and in a line perpendicular to the central line of the 
northern rail of the main track, at a point 27°39343 from the 
southern terminus of the failroad 3 in Concord, N. H. The eastern 
end of the base was 12-21 feet north of the center of the northern yee

With these data and the horizon al angles chiattieed at the two 7 
stations, the altitude of the hight point of the mountain above

mouth, the Concord terminus of the Northern road was found to 
be 236: 0 feet above mean half tide. 
We make, therefore, the height of the mountain 2726°57 feet 
above the sea level. 
is mountain is an isolated peak, and has already become 
historic from the fact that it w was the namesake of the U. 5.
