above mean tide, where its base, more fully exposed several 
years ago during the construction of a railroad than at the 
present time, was observed by Mr. Dodge to be a somewhat 
arched bed of "loose, clean, rather fine gravel." This was 
seen to be overlain by till, which exhibited traces of an im- 
perfect stratification close to their line of separation but 
above is entirely unstratified. 
In the autumn of 1888 it was my good fortune to find two 
other sections of drumlins which more amply display this in- 
teresting structure, namely, the Third and Fourth Cliffs of 
Scituate, Mass.. about twentv-five miles southeast of Boston.

These drumlins, respectively about 70 and 60 feet in hight, 
consist of till upon their whole surface and to a depth that 
varies from If) to 25 feet and more, but below include beds of 
^t£ IG L 5, Action of Third Cliff: length, about ;.ooo feet: hight. 70 feet above the sea. 
( I he base of the section is at the top of the shore of boulders, 10 feet above the sea.) 
modified drift that attain in Third Cliff a thickness of at least 
:{<> to 40 feet, reaching to the boulder-strewn shore, and in 
Fourth Cliff a thickness of 10 to 20 feet, being seen there to be 
underlain by till and to be also in part interbedded with it.
