which crowded far up, and even overflowed the sides of this 
valley, and when all had melted away, left as witnesses 
of the floods these placid lakes. These sheets of water, 
however, are not scattered at random over the face of 
New England. In this valley and the neighboring parts 
of Maine, they are arranged in a general north-west and 
south-east course, following that of the rivers. This 
direction is probably due to the fact that the valleys 
cut across the general north-east and south-west course 
of our mountain ranges, which compose the Appalachian 
chain. 
We had no time to search for glacial scratches in the 
Ossipee valley, but cannot doubt that on examination they 
will be found pointing towards Mount Chicorua, where, 
according to Dr. C. T. Jackson,* they follow the gene- 
ral north-west course of this valley. 
Riding up the Conway valley, with Kearsarge on our 
right, and the Mote Mountains on our left, up through 
Bartlett to Jackson, we observe moraines innumerable 
rising high up the sides of the valley, and covered 
with boulders, revealed more distinctly in all the cleared 
lands. Above these moraines rise rounded and embossed 
rocks, while the evenly terraced valley, over which the 
' road passes, shows that at a former period (though long 
after the close of the glacial epoch) the river, then a se- 
ries of broad lakes, rearranged and resorted the confused 
materials composing the mounds left by the melting 
glacier, into finely, evenly stratified fresh-water deposits, 
which now form the arable land of the plains, over which 
are scattered the picturesque villages and hamlets so fa- 
miliar to the White Mountain tourist.
