IN: THE WHITE MOUNTAINS. 265 
surface of the reddish sienite had here been polished 
smooth as porcelain, as seen in little patches which had 
survived the centuries of weathering by frosts and snows, 
which has effaced most of the slighter traces of glacial 
action in our mountain regions. Here the marks point- 
ed north 30° east. There were also strange marks in 
the rocks, called lunoid furrows, which are crescent-shaped 
depressions in the rock, with the concavity looking to- 
wards the north. The origin of these lunoid furrows 
have been thus explained. It is known that the glacier 
is in constant motion, advancing a few inches in sum- 
mer, and then contracting in winter. Now imagine a 
stone frozen into the ice, and thus acting as a gouge. 
Pushed onward and then withdrawn by the powerful 
hand of the ice-king, it soon wears this peculiar 
shaped hole, then turns over out of the rut, and catches 
again in some inequality of the rock, and makes another 
lunoid furrow, or perhaps a series of four or five, often 
very regular in form, though the distance between them 
may vary. : 
Crossing over the range of mountains north of Mount 
Kearsarge into Stowe, Maine, we descend into the 
charming valley of the Cold River. This is a branch of 
the Saco, and, though now comparatively unknown, it 
must in future attract many travellers. We pause at 
the entrance of Evang Notch, a mountain pass of great 
interest, and far surpassing Pinkham Notch in grandeur, 
reminding us rather of the White Mountain Notch. The . 
gate of the pass is guarded on the west by Mount Royce, 
on the east by Speckled Mountain, whose nine spurs ra- 
into the towns of Stowe, Albany, and Stoneham. 
On the broad, flattened, glaciated summit of Speckled 
tain ice-marks abound, pursuing a course north 15°
