702. Well at South Hadley Center, Hampshire County. 
[Well begun November 15, 1904; completed March 6, 1905T Authority, Ernest Lyon, driller. 
Samples preserved. Geologic correlations by S. Sanford.] 
After passing through the sand and hardpan of the drift (Pleistocene) this well struck the 
brown, gra} T , and red sandstones and thin beds of shale that have been classified as the 
Longmeadow sandstone formation. This is one of the four formations into which the rocks 
of the Triassic (Newark) system in Connecticut River Valley have been divided in Massa- 
chusetts and is the best water bearer of the four. An account of some of the wells drilled 
in the Triassic rocks of Connecticut River Valley and a consideration of these rocks as water 
bearers are contained in Water-Supply and Irrigation Paper No. 110, "Contributions to 
the hydrology of the eastern United States," by M. L. Fuller.
