GLACIAL DRIFT. 245 



the meadow. This came from the cliff 500 feet above the plain a few- 

 years since, and after striking the meadow bounded a distance of 10 rods 

 to the spot where it now lies. A series of moraines occurs at the saw- 

 mill on Rocky branch, and for half a mile above. 



Ellis River Glaciers. A recent visit to the main Ellis river and the 

 Wildcat Branch in Jackson enables us to describe the markings left by 

 the ice in its descent. Dr. Packard has called attention to them in a 

 paper cited above. He gives scarcely any details, and relies upon the 

 course of the striae, mainly, for the proof of the existence of the local 

 glaciers. These have been credited to him in the table of striae. One 

 remark is of importance : " Riding up the Conway valley, up through 

 Bartlett to Jackson, we observe moraines innumerable rising high up the 

 sides of the valley, and, covered with boulders, revealed more distinctly 

 in all the cleared lands. Above these moraines rise rounded and em- 

 bossed rocks, while the evenly terraced valley shows that the river, then 

 a series of broad lakes, rearranged and re-sorted the compressed mate- 

 rials composing the mounds left by the melting glacier into finely, evenly 

 stratified fresh water deposits." I noted some of these moraines in Bart- 

 lett, or the edge of Conway, in the woods south of the Interval station. 

 Mr. Bigelow's fine summer residence is upon one of these moraines ; and 

 the blocks are quite numerous among the pine trees further south. The 

 striae S. 60° W., observed by Vose on the south side of Mt. Pequawket, 

 must have been made by a branch from the east. After reaching the 

 Ellis valley, there is a proper moraine of a local glacier just below Good- 

 rich falls. In the edge of Jackson is a ridge in the middle of the valley, 

 about an eighth of a mile long, with many large boulders upon its sur- 

 face. Small cuts in it show the presence of some boulder clay. This 

 reaches nearly to the bridge across the Ellis river, shortly below the en- 

 trance of the Wildcat Branch, and in a proper medial moraine. On 

 reaching the village of Jackson, the valley divides ; and I will first refer 

 to the glacial traces seen on the main stream. There are large moraines 

 upon both sides of the valley north and south of a large boarding-house, 

 perhaps an eighth of a mile west of the falls. Those south are at the 

 base of Cobb's hill, and are less important than those on the other side. 

 About two miles up the valley are lateral moraines. About opposite the 

 mouth of Miles brook the ledges show striae running down stream, and
