those given in the map^). It is not until we reach the districts 

 examined by the Danish Expedition that the facts relating to 

 the eastern frontiers grow clearer, though still a good deal is 

 left to be done. In the extreme E. we have Archaean rock. 

 On this, at C. Fletcher, rest Paleozoic strata. Then, if we follow 

 the boundary southward, we shall find that in the contact to 

 the Archaean rock more and more recent rocks appear. This 

 may partly be connected with faults and with the erosion which 

 was at work in connection with the origin of Hurry Inlet; be- 

 sides, this circumstance depends on a general though very slight 

 inclination of the rock towards the S. It looks as if the same 

 dip should assert itself on the W. frontier towards the Archaean 

 rocks of the central mass, since even here furthest south the 

 older formations seem to be lacking on the boundary between 

 Jurassic and Archaean rocks. But here the real facts are too 

 little known to allow of any conclusion being drawn. 



Above the С Fletcher formation, at Fleming Inlet, lie 

 strata of the Triassic system, and between the two the forma- 

 tion at Cape Brown, which in age should be nearest the latter. 

 How the Triassic strata appear to the west, we do not know, 

 no observations having been made; possibly they are covered 

 by Jurassic, but still farther west we should most probably come 

 to older and older strata, dipping to the E., as Nathorst' s 

 map also shows. In the interior of Hurry Inlet, between Jur- 

 assic and Archaean, we find formations which should correspond 

 to the strata at C. Brown and Fleming Inlet, which were classed 

 as Triassic.
