of this volume: that the divide 14 to 2 miles north of Meriden, 
is on the borders of the Hartford river-region: that the highest 
part of the divide is near the Hartford flood-level, about 160 feet 
above modern high water in the river; and that over 20 feet of 
terrace sands and gravel, that is, stratified drift, underlies the 
summit plain. The red sandstone outcrops in some places over 
the top and rises into ledges. The overflowing waters eroded the 
sandstone surface, and descended to the Quinnipiac, just below 
Meriden, to swell the stream and increase the height of its 
terrace depositions. 
2. Overflow from Westfleld, Mass., over the Southwick divide, into 
the Farmington Valley.—The village of Westfield is situated 
nine miles west of Springfield, on Westfield River, a large an 
rapidly flowing stream tributary to the Connecticut. The river 
emerges from its confined valley of metamorphic rocks, about 
twelve miles west of the Connecticut River, at “Mt. Tekoa,” 
and there enters the open Red-sandstone area in which Westfield 
is situated. Five to six miles west of the Connecticut, it passes 
through a gap in the Mt. Tom or Divide Range, and enters the 
present Connecticut Valley. The Westfield region is hemmed 
in on the north by the Westfield divide, between it and North- 
ampton, and on the south by the Southwick divide, separating 
it from the Farmington Valley—both made of red sandstone, 
ae ne over the sandstone, levelled deposits of stratified
