414. J. D. Dana—Depression of Southern New England 
passage is every where abrupt from the even plain to the rising 
hill-side, that is, from the terrace of stratified drift to the un- 
stratified drift of higher levels, and this is true quite to Savin 
Rock on the Sound. On the east side of this bay the same 1s 
true; but the terrace on that side is mostly wanting, and the 
cape is rocky, so that the fact is less significant. é 
_ The following are the elevations of the plain at different 
points between the Sound and Mt. Carmel village.
