THE ESKERS OF NOVA SCOTIA. PREST. 373 



should be. On an elevated plateau south of AVcntwor^h 

 Lake it is broken up and meanders in a curious way com- 

 pletely independent of water-sheds, drainage slopes, and 

 streams. Fuither west at the foot of a lake at Hectanooga 

 it reaches its greatest development; sixty or seventy feet 

 high it dams back a lake, and along its crest is built a highway. 

 South west of this I did not trace it, but it is said to extend 

 nearly to the sea-shore. Its eastern extension crosses some 

 of the highest land in the western part of the province near 

 the head-waters of the Liverpool, Tusket, Sissiboo, and Bear 

 Rivers, where it is often 30 to 50 feet high. Its height and 

 regularity makes it one of the most noteworthy natural 

 features in the province. Its total length must be 60 or 70 

 miles. The eastern end of this esker is seen crossing the 

 watershed and descending easterly to the Liverpool River 

 at Kejimkujik. A more northern branch of it crosses 

 the lake called the Frozen Ocean by a string of islands and 

 gravel banks. Advancing up the next slope it crosses to 

 Annapolis-Liverpool road north of Maitland. From thence 

 it goes eastward, and 25 or 30 miles east of this a like ridge 

 crosses the Nova Scotia Central Railway on or near the 

 same latitude. 



West Brook Esker. — A short ridge crosses the West Brook 

 of the Liverpool River at the point where the higher level 

 lands bieak off into the slope that descends to the river. 

 Like may others, it marks a change in the angle of descent. 



Middlefield Esker. — To the east of this and on the same 

 course, a well developed ridge crosses the Annapolis-Liverpool 

 road at Middlefield, This may possibly be the extension 

 of the West Brook esker. It is a well defined ridge of gravel, 

 rising and descending with the slope of the land on the 

 watershe d across which it runs. Like most of the others it 

 crosses the general course of drainage as well as the direction 

 of the glacial movement.
