234 J. D. Dana on Glacier movements along valleys. 
Reports by Wm. W. Mather, an assiduous laborer in this field 
of research. 
We learn, first, from the scratches on the rocks outside of the 
larger, valleys of New England—that is, over its higher lands— 
that the general course of the continental glacier covering New 
England was between S. 20° E. and 8. 50° E. The true course, 
_ deduced from the sation is to given, and so throughout the 
following payes. 
On the high region of western Connecticut (1000 to 1200 feet 
above the sea), about Warren and Litchfield, the author found 
the courses of the scratches S. 29° E.; more to the west, east of 
Kent, on Kent mountain, S. 19° E. ; to the south of Kent, about 
Newtown , >. 38° EH. Percival observes that over this western 
part of Connecticut the direction of the transfer of drift was to 
the S.S.E. (probably meaning S. 20°-25° E.); and he cites as 
ty, Conn., near r Norfolk, S. 20°-25° E., and Hitchcock, for that 
on Mt. Tom, the highest elevation near Litchfield, 8. 17°-92° E. 
West of the State of Connecticut, — it and the Hudson 
river in Dutchess county, not far t of Arthursville, I ob- 
tained for the course of scratches (tick were common over the 
region) S. 24° E. Mather found in Putnam county (south of 
Dutchess), near Patterson, S. 17° E. to S. 22° E.; in Dutchess 
county, mostly betwee n 8 15° E. and § 30° E., bits in some 
places S. 35° E.; and ‘hott oF Dutchess county, in Columbia 
any to S, 80° B, 
top of Tom Ball in Alfo na +: Sor north of Mt. Washingto®, =| 
S. 48° E.; on the east slope of the Taconic ridge near Pittsfi tisfield = | 
(in same latitude nearly with the Shaker village above alluded 2 
to) and at Egremont, on the west slope, about S. 50° E.; 4 7 
little south of the latter, on Lenox mountain, near the road from} 
Richmond to Lenox, 8. 38° E. Scratches observed by the we 
ter on Mt. Everett: tiended S. 27° E fs 
Again Dr. H. obtained for the course in middle Granville, 20 | 
miles west of the Connecticut, S. 38° E.; between Otis 4 and > | 
Becket, 30 miles west of the Connecticut, and farther north | 
as i the average directio tion S. 24° E. vite obtained in Royalstom 
y 20 miles west of the Connecticut, S. 18° E. to S. 88° E-
