aneroid readings made by myself in traversing some of the roads 

 and the railroad shown on the map. The elevation of the top of 

 Covey hill has been furnished me as noted by Dr Gilbert. 



The crest of Cove} 7 hill is devoid of marks of water action 

 attributable to waves or glacial streams. Toward the base of the 

 northern slope of the hill, unmistakable evidence of water action 

 begins to appear at about 570 feet, and from that level down to 

 the rather rolling low ground at its base there is first a succession 

 of benches and then of distinct beaches. These are encountered 

 in going from Covey Hill postoffice to Vicars, from the top of 

 Covey hill to the main road west of Stockwell, and in descending 

 the hill by the northwest road which enters Franklin Center. 



On the road to Franklin, just; beyond the fork in the roads, 

 there is a small sand flat or delta on a little stream at an elevation 

 of 720 feet (aneroid) ; and again, on the same road just south of 

 Franklin and above the point where. a/' dug road " comes in from 

 the northeast, there are low, flat ridges sloping westward at an 

 elevation between 700 feet and 800 feet (aneroid reading dis- 

 credited). These are the only exceptions I noted to the general 

 absence of water levels on this hillside above 570 feet, and these 

 cases are of the discontinuous kind which may be attributed to 

 temporary conditions attending the drainage along the margin of 

 the ice sheet as the front retreated from the northern slope of the 

 hill. 



Dr Gilbert, in his manuscript notes, records a well marked beach 

 on the road from Covey hill to Vicars at an elevation of 450 

 feet. He states that he noted ridges above that level, but that 

 they lacked the element of horizontality and were hence thrown 

 out of the evidence he sought for the determination of the upper 

 marine limit. 



In going over the hill to the west and down the road toward 

 Stockwell, a shelving terrace is encountered at 580 feet which 

 drops off in the form of a low cliff to a shelving flat, which joins 

 the cliff base at 570 feet. No signs of water action in the way of 

 waterworn pebbles are noticeable, but some form of erosion has 

 evidently taken place at this level. Going farther down this road, 

 the till is cut back in the form of a good bench with a cliff. The 

 road from Stockwell to Franklin Center runs on this bench at
