The latest information on the I'leistocene of Labrador 

 is thai given in a paper by Dr. Packard in the memoirs of 

 the JJoston Society of Natural History for 1<S()7. The 

 deposits are said to consist of boulders, Leda clay and sand, 

 and raised beaches, which, on the authority of I'rof. Hind, 

 are stated to reacli an elevation of 1 ,200 feet above the sea. 

 The hills to a height <if 2,r»00 feet are rounded as if by ice 

 action. Some higher hills present a frost-shattered surface 

 at their summits. Xo directions of striae are given, and 

 they appear to ])e rare. Mr. (_'am[)bell, author of " Frost 

 and Fire," mentions examples with course X. -to K. in the 

 strait of Jielle-isle. It is remarkable that true boulder- 

 clay is rare in Labrador, thougli loose l»oulders are 

 abundant in the vallc^ys and on tlii^ inland tal»le-laiid. 

 Dr. Packard attributes the absence of boulder-clay to 

 denudation. This may be the case, but it is to be observed 

 that, on that view of the origin of boulder-clay which 

 attributes it to ice-laden Arctic currents, there must 

 always have been in tlie course of su'di currents arciis of 

 denudation as well as areas of deposition, and an elevated 

 table-land like; that of Labrador, in a high northern lati- 

 tude, may well have been of the former character, or may 

 have been a lain I area C(jvered wdth snow aiul ice at the 

 time -i' the deposition of the boulder-clay. In many 

 res[iects, though less elevated, it resembles the aspect of 

 the Cordillera region of the west as described bv Dr. (}. M. 

 Dawson.
