266 ICE-MARKS AND ANCIENT GLACIERS 
east, following the course of the valley at this point, 
and pointing PeT a | higher peak situated a little to 
the northward. 
In one place a beautiful beryl, in fine crystals of which 
the coarse granite abounds, has been sliced off by the 
abrading agent, and polished even with the surface of the 
feldspar matrix. There are broad surfaces of rock planed 
down by ice, both on the north-western and north-eastern 
slopes, showing that the ice must have slid down in both 
directions from the reservoir of snow which rested on the 
water-shed between the two valleys. Here, also, occur 
numerous lunoid furrows, pointing in the same general 
direction as the straight fine grooves. In the fields, at 
_ the bottom of the mountain, are several parallel trains of 
boulders, formerly lateral moraines, which lie ten or fif- 
teen rods apart. We were informed that these windrows 
of boulders stop the plough, and it is only possible to 
turn the sod in the intervals between them, which are 
entirely free from boulders. 
On Mount Baldface, which lies about three miles 
west of Speckled Mountain, and is composed of a pale 
fine sienite, with an unusually perfect rift, enabling it 
to be split into long thin slabs for building purposes, 
the glacial marks assume quite a different direction, run- 
ning north 10° to 15° west. On the north-east face, per- 
haps five hundred feet below the summit, may be seen 
strie and lunoid furrows in abundance, running over 4 
smoothly glaciated spur, on which the striæ run north 10° 
west. Here the lunoids were quite abundant. Some 
were ve large, oe from one to three feet in 
aia dell of the mountain saab covert angular 
boulders of a peculiar porphyritic sienite, containing
