THE Norwegian expedition to the Antarctic under Mr. L. Christensen which aims at mapping from the air the partially known coast-line of Antarctica between long. 100° W. and 10° E. is reported by The Times to have discovered one of the missing stretches of the coast. Mr. Wideroe, flying from the Thorshavn, found land between Queen Maud Land to the east and Princess Ragnhild Land to the west in about lat. 69° 30′ S. and long. 38° E. Even more interesting than this completion of the coast-line south of the Indian Ocean was the discovery by another flight of a mountain range extending westward for at least two hundred miles from lat. 71° 30′ S. and long. 26° E., with peaks rising to 6,000 ft. and 10,000 ft. This range would appear to lie in Princess Ragnhild Land and to extend into the new land. Farther east, it may be remembered that in 1930 Sir Douglas Mawson found mountain ranges in the interior of Enderby Land. In all probability, these ranges will prove to be fault ranges along the edge of the plateau of the eastern Antarctic.
