smooth, but not striated, in the sounds." — Short American Tramp, 

 pp. 68, 107. 



Cape Charles and Battle Harbour : — " But though these har- 

 bours are all frozen every winter, the rocks at the water-line are 

 not striated" {y. 68). 



At St. Francis Harbour : — ". The water-line is much rubbed, 

 smooth, but not striated" (p. 72). 



Cape Bluff: — " Watched the rocks with a telescope, and failed 

 to make out striae anywhere; but the water-line is everywhere 

 rubbed smooth" (p. 75). 



Seal Islands : — "No stria are to be seen at the land-wash in 

 these sounds or on open sea-coasts near the present water-line " 



(p- 76 )- 



He only mentions having here found striatums in the three 

 following places along the entire coast of Labrador visited by 

 him ; and in regard to two of these, it seems very doubtful that 

 the markings were made by modern icebergs. 



Murray's Harbour : — " This harbour was blocked up with 

 ice on the 20th of July. The water-line is rubbed, and in some 

 places striated" (p. 69). 



Pack Island: — "The water-line in a narrow sound was po- 

 lished and striated in the direction of the sound, about N.N.W. 

 This seems to be fresh work done by heavy ice drifting from 

 Sandwich Bay ; but, on the other hand, stages with their legs in the 

 sea, and resting on these very rocks, are not swept away by the ice" 

 (p. 96). If these markings were modern, why did not the " heavy 

 ice " remove the small fir poles supporting the fishing-stages ? 



Red Bay : — " Landed half-dressed, and found some striae per- 

 fectly fresh at the water-level, but weathered out a short distance 

 inland" (p. 107). The striations " inland " could not have been 

 made by modern icebergs ; and it does not follow that because 

 the markings at the water-level were not weathered they were 

 produced by modern ice. 



These are the evidences which he found that icebergs striate 

 rocks, on a coast of which he says that, during the year he visited 

 it, " the winter-drift was one vast solid raft of floes and bergs 

 more than 150 miles wide and perhaps S000 feet thick at 

 spots, driven by a whole current bodily over one definite course, 

 year after year, since this land was found " (p. 85). 



But Mr. Campbell himself freely admits that the floating 

 ice which comes aground along the shores does not produce 

 strise. " It is sufficiently evident," he says, " that glacial stria 

 are not produced by thin bay-ice" (p. 76). And in e Frost and 

 Fire/ vol. ii. p. 237, he states that, "from a careful examination 

 of the water-line at many spots, it appears that bay-ice grinds 

 rocks, but does not produce striation,"
