Glacial Marks in Labrador.

feet above the water's edge, and below the line of lichens, which 

 are probably kept at a distance by the sea spray. 



Here on the polished and smooth shore, somewhat like that 

 represented in Plate in, we observed a number of remarkable 

 lunoid furrows (Fig. i). These crescent-shaped depressions ran 

 at exactly right angles to the course of the bay, and were from 

 five to fourteen inches broad by three to nine inches long, and 

 the depression was deepened in the hollow of the curve, for 



about an inch. Their inner, or concave, edge pointed south-west, 

 the bay running in a general S. W. and N. E. direction. They 

 were scattered irregularly over a surface twenty feet square. 

 Where several followed in a line, two large ones were often suc- 

 ceeded by a couple one-quarter as large, or vice versa. Also at 

 Tub island on the southern side of Hamilton bay, similar mark- 

 ings, though less distinct, occurred about the same distance above 

 the sea, and on a similar polished quartzite. 



These marks agree precisely with a number of lunoid^ furrows 

 which I have observed on a shoulder of rock near the summit of
