Berkshire and the state of New-Yor 
The latitude of the county of Berkshire was ascertained 
by Messrs. Ewing, Rittenhouse, and Hutchens, commis- 
sioners appointed to survey the boundary line between the 
states of Massachusetts and New-York. According to 
their Report,* the latitude of the S. W. corner of Massa- 
chusetts is 42° 3’ N., and of the N. W. corner, 42° 44’. 
The course of the boundary line is, according to their re- 
port, N. 15° 12’ 9” E., and the variation of the needle was 
at that time, (July, 1787,) 5° 3’ W. The mage of 
the N. W. corner is, from late observations, 78° 22’ 52.5” 
W. from Greenwich, and of the S. W. corner nearly 73° 
44’. The above mentioned survey gives the length = ca
