The following are the directions of the diluvial scratches in a 



number of localities in different parts of Nova Scotia : — 



Point Pleasant and other places near 

 Halifax, exposure south, very dis- 

 tinct stri^, . . . S. 20° E. to S. 30° E. 



Head of the Basin, exposure south, 



but in a valley, . . . E. & W. nearly. 



La IJave River, exposure S.E., . S. 20° W. 



Petite River, exposure S. . . S. 20° E. 



Bear River, exposure N., . S. 30° E. 



Rawdon, exposure N., . . S. 25° E. 



The Gore Mountain, exposure N., 



two sets of stri^, respectively, . S. 65° E. & S. 20° E. 



Windsor Road, exposure not noted, S.S.E. 



G-ay's River, ex^Dosure N., . Nearly S. & N. 



Musquodoboit Harbour, exposure S., Nearly S. & N. 



NearPictou, exposure E., in a valley. Nearly E. & W. 



Poison's Lake, summit of a ridge, . Nearly N. & S.

Sydney Mines, Cape Breton, expo-

The above instances show a tendency to a Southerly and South- 

 easterly direction, which accords with the prevailing course in 

 most parts of North-eastern America. Local circumstances have, 

 however, modified this prevailing direction ; and it is interesting 

 to observe that, while S.E. is the prevailing direction in Acadia 

 and New England, it is exceptional in the St. Lawrence valley, 

 where the prevailing direction is S.W. Professor Hind has given 

 a table of similar striation in New Brunswick, showinc: that the 

 direction ranges from N. 10° W. to N. 30° E., in all except a 

 very few cases. On Blue Mountains, 1650 feet above the sea, it 

 is stated to be N. and S. As in Nova Scotia, N. W. and S. E. 

 seems to be the prevailing course. In a paper published in the 

 Canadian Naturalist, Vol. VI., No. 1, Mr. Matthew gives a table 

 of striation in the southern part of New Brunswick, in which the 

 South-east direction is decidedly predominant, though there are 

 also some in the South west direction. In this paper will also be 

 found many interesting facts as to the Boulder-clay of NewBruns- 



* The above courses are magnetic, the average variation being 

 about 18° W.
