118 CONNECTICUT LAKE. 



clouds are now. As the wind has moved these clouds, we have at times almost fancied that these clouds 

 were the waves of the sea washing the summits, and that we saw the face of the country as it appeared in 

 former times. 



At the south end of the twentieth basin the highest terraces, No. 4, are the only ones in view, but they expand 

 so as to receive the lower ones within them before arriving at Colebrook, N. H. Here an old bed of the 

 river has interposed No. 3 between Nos. 1 and 2, and has produced other variations, which are represented 

 upon Plate III. Mt. Monadnock in the northeast part of Lemmington, extends to the river, and forms part 

 of the northern limit of this basin. The length of the basin is five and a half miles. Passing still farther 

 to the north, in the towns of Canaan and Stewartstown, N. H., we find still a fine country, with well 

 developed terraces, though the valley is not very wide. In the twenty-first basin of six miles extent, we 

 find great variety in the number, extent and position, of the terraces. Just below the village of Canaan, 

 a rocky barrier limits this basin. At Canaan commences the twenty-second basin, and it is finely developed- 

 A stream comes in from Canada, from Leach's Pond in Averill, uniting with the Connecticut at the village 

 of Canaan, and assisting in the formation of six beautiful terraces on the west bank of the Connecticut. 

 The highest of these is also found on the New Hampshire side. This is the last interesting portion of the 

 river for terraces, that we saw, though we went but a few miles farther. The Connecticut has now dwarfed 

 to a width of 150 feet, from 390 feet at Newbury and from 450 to 1050 feet in Massachusetts and Connec- 

 ticut, and its forces are divided into various tributary streams. We have represented the space of sixteen 

 miles intervening between Canaan and the head waters in Connecticut Lake, in New Hampshire, as 

 forming only one basin, because we have not examined the last twelve miles of its course, and therefore do 

 not know the character of the valley. But we presume, from appearances indicated at the limit of our 

 explorations, that the terraces are quite limited in size and number, in this district. We should have been 

 glad to have examined the shores of Connecticut Lake for any terraces or beaches about its waters. We 

 know by report that the country is very wild, and perhaps the extent of the unbroken forests would 

 prevent the easy acquisition of the desired information. 



We have now stated what facts we have learned respecting the terraces in the valley of the Connecticut 

 River, in Vermont and New Hampshire. Before leaving this valley it becomes us to say what we can 

 respecting the terraces upon its principal tributaries in Vermont : West River, Saxton's River, Williams' 

 River, Otta Quechee River, White River, Wait's River, Wells River and Passumpsic River. Our task 

 will be easy, because of the scarcity of observations. 



TERRACES UPON BROAD BROOK AND WEST RIVER. 



Broad Brook runs through the north part of the township of Guilford, and empties into the Connecticut 

 in the north part of Vernon. At Algiers, the highest terrace on the south side, or No. 3, attracts attention 

 by its size and great height. It constitutes quite a marked plain, and is 497 feet above the ocean. A 

 small stream flowing from the south by the slate quarries, unites with Broad Brook at the foot of this 

 terrace, and appears to have been largely concerned in the formation of these terraces. Other terraces less 

 marked may be seen upon Broad Brook, both above and below Algiers. 



West River rises inWinhall, Londonderry, and Weston, emptying into Connecticut River at Brattleboro. 

 It has had an important part in determining the number and outline of the terraces on the Connecticut, 

 north of the village of Brattleboro. The few glimpses we have had of its surface geology above 

 Brattleboro, have satisfied us that terraces are developed upon its banks in unusual profusion. We were 

 particularly impressed by a view of the valley of West River from the vicinity of the old court house of 

 Windham county. The whole valley for a great distance could be distinctly seen wending its way among 

 the mountains, like some of the fancied views in fairyland. 



Although we traveled three or four miles along the valley of West River, we have scarcely any specific 

 statements to make respecting its terraces. Between Black Mountain in Dummerston and Fayetteville, 

 they were certainly very numerous and well developed. No. 4 is represented upon the map on both sides of 

 the river in this section. Four terraces at the junction of West River with the branch from Williamsville
