﻿Explorations in tlie Labrador Peninsula. 429 



stones, argillites, shales and limestones along with bedded 

 traps and other volcanic rocks and enormous deposits 

 of excellent iron ore, whose mode of occurrence is closely 

 analogous to that of the iron ores of Michigan and 

 Wisconsin. 



The surface of the country is mantled with drift, 

 and there is distinct evidence that the whole Labrador 

 Peninsula, except a narrow strip of very high land along 

 the North Atlantic coast, was completely buried in ice, 

 during a portion, at least, of the glacial period. The 

 movement of this ice was outward in all directions from a 

 central gathering ground. The position of this Neve field 

 was about midway between the east and west coast of the 

 peninsula and between latitudes 53° and 55°, and the area 

 is now characterized by the presence of partially rounded 

 boulders and angular blocks of rocks scattered over hill 

 and hollow. Most of these repose on rocks of the 

 same character as themselves, and have evidently been 

 transported but very short distances from their original 

 positions. They probably; represent boulders of decom- 

 position, but slightly modified by subsequent ice action. 



The various sorts of drift and the forms assumed by the 

 drift are described, although a detailed study of these was 

 impossible owing to the dense forest growth which covers 

 the greater part of the area. 



There is distinct evidence of a post glacial uplift which, 

 however, it is believed was not equal all around the coast, 

 being about three times as great on the south and west 

 marcrins as alono; the north and east coast, where two 

 hundred feet appears to be the limit of raised marine 

 terraces and beaches. 



Appended to the report are lists of the Mammalia, 

 Birds, Food Fishes and Plants found in Labrador, as well 

 as an appendix by Mr. Ferrier on the microscopical 

 structure of some of the rocks collected, and one by 

 Mr. Eaton on the meteorology of the Peninsula.
