198 THE PHENOMENA OF DRIFT, OR 



I have alluded to a few moraines, which I met in my excursion 

 to the White Mounlaiiis; l)nt ihey were not at all remarkable on 

 the route which I took. The irregular and tortuous ones are 

 somewhat common along the western shore of lake Winnipis- 

 eogee. But still better examples may be seen in the pine woods 

 on the west shore of lake Ossipee. Some of these are ridges of 

 considerable length : but they are not near any high mountain. 

 Two or three miles southwest from Adams' tavern in Conway, 

 on the road to Eaton, and in a narrow valley between high hills, 

 are some rather remarkal^le moraines, which need more exam- 

 ination than I was able to give them. The principal moraine is 

 a ridge running lengthwise of the valley, and half a mile long. 

 It appeared to me, in passing it, to be nearly straight. Near its 

 north end is a deep pond. 



The valley of Saco river, between Conway and the Notch, a 

 distance of thirty miles, presents fewer examples of moraines than 

 is usual in a mountain stream : though beds of detritus with steep 

 slopes, do sometimes occur. And in passing from the Notch 

 westward towards Connecticut river, we meet -with few traces of 

 moraines. At the distance of five miles from the Notch, however, 

 and a few rods before we reach Fabyan's tavern, I noticed the 

 remnant of a rather remarkable ridge of gravel, which has been 

 dug away at one end for a road. The sketch, PL VIII, fig. 10, 

 will give some idea of its appearance as we approach Fabyan's. 

 It lies on the north side of a wide valley, running longitudinally, 

 and seems to be the fragment of a lateral moraine. It is about 

 twenty feet high and several rods long. 



I followed the valley above-named fourteen miles from the 

 Notch House, yet saw no other marks of glacial action. But 

 upon, the Ammonoosuc, below the village of Lisbon, I noticed 

 several ridges of gravel and sand, strongly resembling moraines : 

 one of them appeared like that above sketched, though larger: 

 others seemed to have been terminal, and cut through by the 

 river. 



But of moraines in ridges, decidedly the most interesting and 

 instructive case which I have met with, occurs in Andover, in 

 Massachusetts. That region is primary, and somewhat uneven ;
