Mount Mansfield presents a long eonins ridge, which at- 
tains, in the Chin, its greatest clevation of 4430 feet, while the 
Nose, at the southern extremity of the ridge, rises to ‘the height 
of 4094 ft, ay the sea. The evidences of glacial action around 
the summits of this ridge are very decided. The grooves men- 
tioned in the final report of our State Geologists, in close 
proximity to great transported blocks under the Chin, at an ele- 
vation of about 4080 feet, are well preserved, and I was able to 
obtain the following co orrected readings of compass, indicating 
the direction of approach of the glacial mass, viz: N. 23° 
and N. 25° W.., (two readings on the same line), also N. 28° W. 
on another furrow. One of the transported blocks, 25 feet 
long, 15 feet wide, and 11 feet high, was doubtless torn from 
another portion of the mountain, and its present position, as 
it lies perched upon and supported by another smaller boul- 
der, indicates that it had been first lifted, and then had set- 
tled down into its resting place. The surface of the rock in 
situ, aay the great baleen, is rounded, so.as to denote an 
sea, and etic 2 in their general direction with the furrows 
observed on the western face of the mountain near the boulders 
described above. 
A very beautiful evidence of glacial action is furnished by 
the polished knobs of quartz, on the top of the Nose, at an
