BEACHES. 153 



bank upon the side of the hill. Upon the north side of the river, it extends back in the shape of an arc 

 of a circle, as if it were the shore of a small bay. Its height is estimated to be from 600 to 700 feet above 

 the ocean. 



On the west side of the Green Mountains, there are more decided cases of old beaches. At Shaftsbury 

 Center there is one quite distinct, which is 643 feet above the ocean. It may extend to Arlington upon a 

 ridge in the center of the valley, much like a terrace. At Shaftsbury depot the lithological character ot 

 the small sorted pebbles is so very marked, that not even the most inveterate opposer of our theory of their 

 formation could doubt that they were water-worn. We have not seen a finer example of a modern beach 

 on any part of the shores of Lake Champlain. 



On the map we have marked a beach from Cuttingsville to Kutland on the east side of the railroad, amid 

 which are some moraine terraces. 



Perhaps there is a beach commencing near the village of Pittsford, and continuing north to Forestdale in 

 Brandon ; being found along the west slope of the Green Mountains, and above the Champlain clays, fring- 

 ing their borders. We should estimate its height at diiferent places from 600 to 800 feet above the ocean. 



A still finer example may be found in the east part of Ripton, lying partly in Hancock, near Flint's 

 tavern upon the top of the Green Mountains. This beach is composed of stratified sand and gravel, and 

 has the proper form of a beach, approaching a terrace. It overlooks the whole valley west of the mountains, 

 .and is 1806' feet above Middlebury, 1696 feet above the Champlain clays, and 2196 feet above the ocean. 

 It is the highest beach that we have measured in Vermont. 



In the northwest part of Norwich there are two beaches at the heights of 1287 and 1337 feet above the 

 ocean. They are upon the same hill not more than half a mile apart. 



In Strafford at the Copperas Works there is another beach. It is situated upon the hill back of the 

 Copperas Works, 150 feet above them, and is 1340 feet above the ocean. It has a distinct terrace form, 

 and is 22 feet below the top of the hill ; the space above the beach being rocky, the cliffs against which 

 the waters may have dashed in former times, and worn off materials for this beach beneath. 



We are inclined to regard the deposits on Thetford hill as an ancient beach. The village is 878 feet 

 above the ocean. 



There is a beach on the east side of Connecticut Kiver in the northwest part of Lyme, N. H. 



In the southwest part of Newbury on the road to East Corinth, near the height of land, we measured 

 an ancient breach that was 1488 feet above the ocean. Another, half a mile west of this one, was 1239 

 feet above the same level. On the east side of the Connecticut, in Haverhill, N. H., there appeared to be 

 quite an extensive beach, as we saw the surface of the country from Mt. Pulaski. 



Passing up the Connecticut, in Ryegate, Barnet and Waterford, there are accumulations of water-worn 

 materials which have been referred to sea beaches. We are not sure but that a re-examination of them 

 would lead us to refer them now to old Sea Bottoms. 



East of Connecticut Kiver in New Hampshire are the highest beaches that have been measured in this 

 country. At Franconia Notch there are beaches at the heights of 2449 and 2665 feet above the ocean, 

 and at the White Mountain Notch at the height of * 1569 feet above the ocean. These were measured by 

 the Principal of the Survey. 



In Victory (west part) the materials are water-worn at a height of 1738 feet above the ocean, and may 

 be regarded as forming an old beach. 



In North Hardwick and Greensboro there was an old beach, the top of which is 1240 feet above the 

 ocean. Others of about the same height may be seen upon the south side of the La Moille River in Elmore 

 and Woodbury. 



In the west part of Fairfax, on the La Moille Eiver, above the terraces, are accumulations referable to a 

 former shore, either of Lake Champlain or the ocean, at least 350 feet above the lake. 



In the valley of Lake Memphremagog we have measured two or three beaches. One on the western side 

 of the lake in Newport is 365 feet above Memphremagog, or 1060 feet above the ocean. One or two 



* Said to have been measured by Prof. A. Guyot. It is at the same elevation as the White Mountain House.
