country. One of them is upon the hill south of Pollard's hotel in 

 Masardis. Another is near the height of land between Weld and 

 Wilton. This one is more or less connected with very high terra- 

 ces. Another is high up on Beech hill, of the Saddleback range, 

 io Franklin county. There is a great amount of detritus collected 

 about the small ponds at the head of Sandy river, perhaps referri- 

 ble to moraine terraces. Lastly, it seems as if there must be some 

 ancient beaches among the numerous sandy hills in Wayne and 

 Leeds, far above all existing streams. In Leeds one of these sandy 

 accumulations has been torn asunder by the wind, and the sand is 

 being blown south-easterly, much to the detriment of the cultivated 

 fields adjacent. A potatoe patch was covered up in this way to 

 the depth of thirty feet. These hills of moving sand are called 

 Dunes or Downs. 



We have not been able the past year to make any further obser- 

 vations upon the very interesting fossiliferous marine clays that 

 skirt the sea shore and the sides of the principal rivers for a con- 

 siderable distance inland. 



Terraces. 



Nor have we been able to observe or map many of the terraces 

 lining so many of the beautiful rivers and lakes of Maine. Kenne- 

 bec river, particularly above Skowhegan, exhibits these phenomena 

 very finely. We were able to map them carefully for about thirty 

 miles of the way below the Forks, and might have published a 

 map of them here, but preferred to defer its publication until we 

 should be able to give a map of them along the course of the whole 

 river. We will, however, state a few general facts concerning 

 the surface geology of this river, beginning at its source. 



The Kennebec river rises in Moosehead lake, not at the extreme 

 southern angle, as one would naturally suppose, but from the 

 south-west side several miles above Greenville. It rushes out of 

 the lake a large river from the very first. Until it reaches the 

 Forks, it is an exceedingly rapid stream, fiilling hundreds of feet. 

 This section of the route is probably deficient in terraces ; yet we 

 have not explored it, as there are no roads along the shores, and 

 navigation with canoes is impossible. The immediate banks we 

 understand are rocky, the river passing through a gorge. 



The Forks of the Kennebec derive their name from the junction 

 bf Dead and Kennebec rivers. Terraces are very abundant here.
