GLACIAL DRIFT. 2X1 



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 Coos flats from descending to Barnet. Certain striae 

 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. f 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 striae 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 striae. 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.
