MAEION AND EAST MACHIAS. 85 



largely ruade up of granite, slates, and the harder sedimentary rocks, and 

 in both are mucli rounder than the stones of the streams of this region not 

 in the lines here indicated for the glacial gravels. These points had to be 

 carefully studied before it became evident that the plain of rounded gravel 

 situated in the valley of the east branch of tlie Mattawamkeag between 

 Smyrna and Haynesville, where the slope of the river coincided with that 

 of the glacial stream, was really an osar-plain and not ordinary valley drift. 



LOCAL KAMES IN MARION. 



A short kame is situated on the east side of Rocky Brook in the 

 northern part of Marion. Another is found near the southeast angle of 

 the northern division of Gardners Lake. It is a narrow ridge rising 15 to 

 20 feet above the luarine clay, and is about half a mile long from east to 

 west. It has the direction of a terminal moraine, but appears to consist 

 wholly of water-washed gravel. 



On the western side of the long point of land which projects from the 

 eastern shore of Gardners Lake, so far as almost to divide the lake into two 

 separate lakes, is a broad ridge or plain of rounded gravel and cobbles. It 

 has been eroded by the waves on its western side so as to form a prominent 

 beach cliff. 



These gravel deposits of Marion do not appear to have been formed 

 by a single glacial stream, and therefore they are not classed as a system. 

 There are many old beaches in Marion on hills that would be exposed to 

 the surf while the sea stood at higher level than now. 



EAST MACHIAS SYSTEM. 



This system begins abruptly in T. 18 near where the road from East 

 Machias to Crawford is intersected by the road leading west from Dennys- 

 ville. The gravel here takes the form of a single two-sided ridge 10 to 30 

 feet high. Going southward we here and there find two or more ridges 

 inclosing kettleholes, and then the gravel soon becomes discontinuous. 

 Still farther south the gaps become longer and the gravel ridges shorter, 

 until the system ends as a series of small rounded hummocks or cones, 

 separated by intervals of from one-eighth to one-half a mile. The last of 

 the gravel hillocks which I could find was a short distance south of East 

 Machias Village. South of this point were a low pass and a plain covered 

 by marine clay. Although the system ends several miles north of the open
