GLACIAL DRIFT. 211 
to commence with the Passumpsic. The great westerly bend of this 
valley below Dalton, and the sudden fall of the land, may have prevented 
the ice of the upper Cods flats from descending to Barnet. Certain strize 
in West Littleton, near Milliken’s saw-mill, cross the Connecticut, and 
ascend Gardner mountain in preference to following around the lowland. 
Our numerous observations in Littleton, Lyman, and Monroe show that 
the prevailing course was a little west of south, conforming both to the 
longer axis of the Gardner range and the Connecticut valley. The whole 
area of this westerly course may be readily referred to the Connecticut 
Valley movement, of which more will be said beyond. 
Another area, showing a course west of south, is in the Lake District. 
We have on the south slope of Pequawket, S. 6° W. (misprinted in the 
table); Madison, S. 7° and 12° W., besides S. and S. 2° E.; Brownfield, 
Me., S. 18° W.; Eaton, S. 3° E. This area is essentially a valley sloping 
southerly; but there are no indications of this direction in its continua- 
tion in Ossipee or Wakefield, nor in the broad opening to the south- 
west between the Chocorua and Ossipee mountains. The striz point 
south-east in both these localities. Hence the reason for this course 
in the Lake District is not obvious. Probably extensive explorations in 
Maine will be required for the solution of this problem. 
Those nearer the coast might be referred possibly to iceberg agency, 
or to some connection with the ocean. They are at Cape Elizabeth, 
close to salt water, S. 8° W.; at Limington, Me., S. 33° W., numerous 
and well marked for half a mile’s distance, seen in crossing a hill; at 
Danville Junction, Me., a little west of south; and at Bow lake in Straf- 
ford, S. 31° and 58° W. The usual direction in this neighborhood is 
fairly at right angles with these. Is it possible that these are scanty 
relics of a once abundant south-west glaciation? Some of the lenticular 
hills, about to be described, are arranged in a line suggestive of a con- 
nection with a south-westerly current, much more extensive than is indi-. 
cated by the striz. The course of S. 59° W. in Sutton cannot easily be 
classed with either of the foregoing. 
We cannot properly appreciate the importance of this movement 
without reference to other observed examples obtained outside of New 
Hampshire. In Maine they are S. 8° W. at Saco, and about the same at 
Rockport. In Vermont they are S. 50° W. at Halfax centre; S. 28° W.
