THE ESKERS OF NOVA SCOTIA. PREST. 375 



feet high, with a narrow top. Near Round Lake, Guysboro 

 County, is one about fifteen feet high and a half mile long; 

 it is very narrow and runs north-east. An interesting esker 

 is said to run North from the Northern boundar}-^ of Pictou 

 Town, across Acadia Farm and into the woods beyond. A 

 good section of it was made by the highway near its origin. 



Other eskers exist in the Province, but quoting from 

 memory, the above are all I can recall just now. 



Cross Drainage System. — The most noticeable feature 

 of these eskers is the fact that the most of them cross the 

 present drainage system of the country. Few of them 

 run parallel with the main streams. 



Eskers of Maine. — Turning to the eskers of the United 

 States, those of Maine are most worthy of notice. Mr. 

 George Stone, in Monograph XXXIV of the U. S. Geological 

 Survey, has reviewed the work of other geologists on this 

 subject. Because of this review, his conclusions on the 

 eskers of Maiiie are examined below. 



Cross Drainage System. — These eskers, like our own, 

 meander over hill, valley, and plain alike. They often 

 pass from one valley to the valley of another stream, crossing 

 a divide from 200 to 400 feet high. In level or swampy 

 land they form natural roadways, and have been used as 

 such. Quoting him, we read: "These great embankments 

 reaching from 20 to 140 miles, cross rivers, valleys, plains 

 and hills, skirting hill-sides far above the valleys, meandering 

 across plains where no obstructions exist to cause it to 

 meander." They are very variable in height and breadth, 

 a narrow ridge a few feet wide being succeeded by a portion 

 of the same ridge 100 to 200 feet wide. As in Nova Scotia, 

 they often divide and re-unite, are interrupted, or spread 

 out into lines of mounds.
