WAYNB-MOISTMOUTH BRAIfCH. 193 



terrace are much rounder tliau those of the Androscoggin flood plain or 

 those in the bed of the river, and no continuous sheet of such drift is found 

 along the river. This plain is situated 2^ miles west of Brunswick Village, 

 and I have been able to find no similar gravels east or southeast of it. I 

 therefore assume this to be the end. 



In a few places this system is situated above the contour of 230 feet, 

 as, for instance, in Readfield and near East Monmouth. In several places 

 the tops of the ridges rise above that contoiir, though their bases are below 

 it. This system is discontinuous from one end to the other, and by this it 

 is meant that the gravels were originally so deposited. The forms of the 

 gravel masses var}^ much and the sj^stem can hardly be classified among 

 the discontinuous systems of lenticular masses. The deposits of this sys- 

 tem are more hummocky and irregular in shape. Nearly all of the plains 

 shoAv some of the characteristics of the delta, but not such deltas as would 

 be formed in the open sea, unless the plain near the foot of Sabatis Pond 

 be such a one. 



The length of the system is 25 miles. 



WAYNB-MONMOUTH BRANCH. 



This series begins a little more than 2 miles east of Wayne Village. 

 At the north end it is a small, rather straight ridge. The stones here pre- 

 serve their till shapes, and the mass is quite like till in appearance, having 

 a rather pellmell structure; yet close examination shows that the finest 

 detritus has been washed out of the mass and the stones are a little water- 

 worn. Farther south the ridge becomes very crooked and meandering and 

 the stones are much more worn and r<_iunded. There are man}^ water- 

 polished bowlders in the ridge. Within less than a mile the S5^stem becomes 

 double, consisting of a continuous low ridge in a valley and a parallel dis- 

 continuous series of domes or short plains forming low broad caps to a 

 series of hillocks lying along the west side of the valley. Just south of 

 Evergreen Cemetery there is a short gap in the series, and then another 

 gravel cap on top of a low rock ridge, which ends near a small stream that 

 flows southwest into Wilson Pond. No glacial gravel appeared along this 

 stream or pond. Right in front of the last-named gravel deposit is the 

 southwestern spur of Mount Pisgah, a higli hill situated in southwestern 

 Winthrop and northern Monmouth. Over this hill the road is made which
