1. On Glacial Movements in Northern New York ; by R. P. 
Srrvens. (Editorial correspondence, dated New York, June 
17, 1873.)—I have just come back from a trip into the moun- 
tains west of Westport, Lake Champlain, returning via White- 
hall through the northwest corner of Saratoga Co. On my trip, ! 
kept constantly in mind the subject of glacial movements, and 
made many observations confirmatory of the view, that the 
ob i in the valleys corresponded to the direction of these

1. Along the valley of Lake Champlain, in the lower lying 
rocks, the general direction of the strie corresponded to the 
longer axis of the valley or north and south, though there was 4 
variation of 20°. 
2, On the higher hills and mountains the strie are more from 
the northwest to southeast. This is very apparent at Split Rock 
Mt., just north of Westport, also in the mountains west toward 
Elizabethtown, and at Mt. Moriah. It is a striking feature of 
the landscape to see the struck side of mountains and the stream- 
ing through the gaps of drift, change as we ascend from the lake. 
3. At Luzerne, Warren Co., on the Hudson River, the dri 
moved down the stream or southward, conforming to the trend 
of the valley, and forms long and high sandy ridges with or wi 
out large boulders, In the town of Corinth, it occurs piled into 
large hills and filling up an ancient valley. 
ut, in Hadley, Saratoga Co., just opposite the village of 
Luzerne, the Sacanadaga River flows from the west, the valley 
opening into the Hudson at almost right angles. The drift flowed 
down’ this valley or eastward, even in some bends having a north 
of east direction.
