feature up to a height of 100 feet or more above the sea. They 
exist as strongly-marked and approximately horizontal and 
gy р] $ 
longitudinal scarps and terraces, frequently bearing bowlder 
g | l À g 
pavements and showing a general correspondence in height with 
the sand plains of the region. They have been observed in all 
] 8 M 
parts of the Boston Basin; but are, perhaps, most favorably 
exposed for study on several of the drumlins northeast of 
Boston, including Breed's Hill, Pleasant Hill, Mt. Revere, Mt. 
Washington, and Powder-Horn Hill. They are also a promi- 
nent feature of several drumlins on the South Shore, including 
Baker's and Otis Hills, in Hingham, and have been observed 
on some of the drumlins of the Nantasket-Cohasset area. These 
may be briefly deseribed, commencing on the north. 
On the southwest side of Telegraph Hill, in Hull, a sloping, 
bowlder-strewn terrace, from 20 to 30 feet above the sea and 
backed by a steep declivity, extends directly across from shore to 
shore. The only terraces on Point Allerton Great Hill are such as 
have probably been formed by the gradual accumulation of soil 
by rain-wash against stone walls at the lower edges of culti- 
vated fields. Three such artificial terraces may be readily 
traced along the southern slope at heights of from 55 to 75 feet. 
The 20- to 30-foot terrace is well developed on the south and 
southwest sides of Sagamore Hill, opposite the steamboat 
wharf, and it may be traced along the southwest side of the 
northern drumlin of World's End. A strongly marked terrace 
extends for a short distance on the northeast side of Planter's 
Hill, at a height of 55 feet. Occasional indications of terraces 
have been noted on the southwestern slopes especially of other 
drumlins in Nantasket and Cohasset, including Strawberry 
Hill, Bumkin Island, Turkey Hill, Scituate Hill, ete. But the 
only others requiring particular deseription are the series on the 
northeast side of Booth Hill, in Scituate. 
This great drumlin extends southeast from Bound Brook, 
near North Scituate, for about one mile. Its northern base is 
closely skirted by the railroad, and on this side it immediately
