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 strie. 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, redrranged 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 
striz 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
