tinct between High street and the next street west, north of the 
grounds of the Wesleyan University, and has a maximum height 
of about 150 feet ; and these proinde excluding a portion in the 
southwest corner, are part of it. A terrace two miles east and 
southeast of Middletown, above where the river narrows, I 
found to have the same height—1650 feet. 
Immediately around the city of Hartford the plain is mostly 
40 to 60 feet above high flood-level in the river (70 to 90 above 
low-water); and in many places it consists of clay to the top. 
But beyond three or more miles there is a rise to higher levels. 
Northwest of Hartford, along the Connecticut Western Rail- 
road, the plain is extensive 6 to 7 miles out at a height near 180 
feet, and between 9 and 94 miles, at a height of about 160 feet.* 
Kast of Hartford, the terrace has a maximum height near 
Manchester, 7 miles out, of 155 to 160 feet. 
_ South-southwest of Hartford, the extended New Britain plain 
is 142 feet in height above the same base—high flood-level in 
Hartford.+ 
*I learn from Mr. W. H. Yeomans, the Superintendent of the Connecticut 
Western Railroad, that the height of the track 9} miles out, near Scotland, is 190 
€et above mean tide level, which is equivalent to about 160 feet above highest 
er as Hartford. 
+ Mr. 8. ©. Pierson, of Meriden, has informed me that the height of the New 
Britain plain is about 172-25 orton agencies Pome ce ne dh 
of Main street and the railroad in gave Mr. 8. ©. Pierson 43°

terrace, gives for the height of the divide above high tide, about 186 feet; or 168
