G. H. Stone — Drift Scratches in Maine. 149 



locally known as George's River) flows in a narrow valley 

 between steep ranges of hills. The ridge on the west side of 

 the valley rises from 200 to 500 feet above the river, that on 

 the east from 600 to 1100 feet above it. The last named range 

 chiefly lies in the towns of Hope and Union, and rises to an 

 elevation of 1240 feet above the sea. East of it is an irregular 

 clump of high peaks and ridges in Camden and Lincolnville. 



Near Union Village the observed direction of the drift 

 scratches is S. 15° W. Near the St. George River from the 

 north line of Union to the north line of Appleton, S. 25° to 

 30° "W., approximately parallel with the valley. Near North 

 Appleton the valley series of scratches is crossed by a later 

 series at an angle of about 75°. These later scratches were 

 found on the east side of the valley, about 100 feet above the 

 river, and run obliquely down the hill toward the bottom of. 

 the valley and almost due west. The limits of this area of 

 local ice-movement have not been determined. 



If we leave the valley of the St. George at Searsmont and 

 pass eastward, our course will lie two or three miles north of 

 the high hills of Hope and Lincolnville before referred to. 

 The westward deflection of the glaciation increases as we pro- 

 ceed. In the south part of Belmont, about five miles east of 

 Searsmont, the direction of drift striae is S. 35° to 37° W. 

 Yet this place is in the broad valley of a stream which flows 

 southeastward to Lincolnville Village, while to the south lies 

 a narrower low pass through Hope and West Camden. Here 

 then, although a natural drainage slope lay off to the southeast, 

 and a favorable pass to the south, yet the ice bore off over a 

 rolling plain to the southwest into the narrow valley of the St. 

 George. Three miles farther east in Belfast, the scratches fol- 

 low the valley of Little River, S. 10° to 20° E. Numerous 

 exposures of the rock in Belfast and Morrill show uniformly 

 an eastward trend of the drift-scratches, sometimes as much as 

 S. 40° E. 



About three miles N.W. of Belfast City there are several 

 places where are preserved portions of a system of drift- 

 scratches which has been nearly effaced by a later glaciation. 

 The local rock is a hard quartzitic slate, well adapted both for 

 resisting glacial corrasion and for preserving the scratches 

 under atmospheric exposure. Usually, when traceable, the 

 earlier scratches have been intersected and nearly obliterated 

 by the later, but at one place the earlier ones were perfectly 

 preserved in a depression of the rock at the southeastern base 

 of a little ledge or steep escarpment barely from half an inch 

 to two inches in height. The line or front of the little precipice 

 happened to lie parallel with the earlier ice-movement and 

 hence offered no resistance to it. The gentle depression was
