one-half mile long and fully 1,000 feet wide. The photographs 
give a better idea of the appearance of the mountain top than 
words can convey. The low trees all lean towards the southeast 
from the influence of the prevalent northwesterly winds, and this 
combined with the parallel striations in the same direction, give the 
beholder a very curious sensation of motion, as if he were stand¬ 
ing on the edge of a rapidly moving flood. East of the summit, 
as soon as one is fairly under the lee of the mountain, one finds 
occasional boulders, but no planed ledges. The east side of the 
mountain is densely timbered, and has, as yet, not been thoroughly 
explored. 
On Ragged Mountain the timber extends almost to the summit, 
so that the planed ledges appear there on a much smaller scale. 
They would be considered, nevertheless, fine examples of ice action 
were not Kearsarge so near. There is one noticeable groove on 
Mount Ragged, cut into the ridge at the northeastern side of the 
summit, which is some twelve or fifteen inches wide and at one 
point nearly the same depth. Its section is a U. This groove 
gradually shallows out in following it southeastward, but, if I re¬ 
member rightly, it is easily traced for twenty-five or thirty feet. 
Although not very large the boulders on Kearsarge are very 
noticeable, for they are composed of a white porphyritic gneiss 
which contrasts vividly with the gray schists upon which they 
often directly rest. 
The porphyritic gneiss when fresh has a slightly bluish tinge of 
color, but the large feldspar crystals, which make up nearly the 
entire mass of the rock, weather to a milky whiteness. There is 
a fragment of one of the boulders on the table. 
A belt of porphyritic gneiss borders the Kearsarge schists on 
the west, the line of contact running along the base of the moun¬ 
tain. The belt is only a few miles wide and it contains, besides 
Mount Cardigan, situated near its northern extremity, no elevation 
greater than 1600 feet. Boulders from Mount Cardigan would 
probably have passed some distance to the north of Kearsarge, 
and it seems probable, therefore, that the boulders found near the 
summit of the latter mountain were elevated over 1000 feet, and 
this while traversing a distance of about seven miles. The boul-
