Glacial Action on the Coast of Greenland. — Barton. 381 
However, when seen from farther south, in a direction trans- 
verse to the direction of the ice-motion, if it passed toward 
the sea, rounded outlines are sufficiently distinct to justify 
tlie conclusion that probably the ice did override this as well 
as the other portions of the Labrador coast. 
At Big Savage island, on the north side of Hudson strait, 
lying off the south shore of Meta Incognita, the southeastern 
part of BafHn land, the summits are well rounded and a mo- 
rainelies directly upon the highest point above Ashe inlet, at 
a hight of 250 feet above sea. There were also observed here 
a large series of elevated beaches which were carefully studied 
by members of the Cornell party. The erratics here are of the 
same type as the underlying gneiss, with the exception of 
scattering fragments of a limestone that we did not find //( 
.situ. 
On the mainland of Meta Incognita the general rounding is 
very pronounced, the motion of the ice having been nearly, or 
quite, parallel to Hudson strait, and passing outward toward 
Davis strait. The underlying rock here is a coarsely banded, 
highly garnetiferous gneiss, containing many beds of a coarse- 
ly crystalline limestone. The erratics are of the same rocks 
as those below, except occasional small fragments of a fine 
grained limestone or dolomite, similar to those on Big island. 
In Cumberland sound, on the south side, at Black Lead is- 
land and Niantilik, there is the same general rounding, though 
the surface of the rock is highly disintegrated and VQxy rough, 
retaining no appearance of glaciation except upon the large 
scale. Here also the motion of the ice was toward Davis 
strait. Erratics are very numerous here, much more so than 
at other places on the west side of Davis strait. 
On the east or Greenland side of Davis strait, Disko island 
was the most southern point visited. At the south end of the 
island directly back of (iodhavn. the cliffs are very precii)i- 
tous, rising at once to a hight of more than 2,000 feet. As 
seen from one of the higher summits at this southern margin, 
the upper surface of Disko presents the appearance of an old 
peneplain with rounded domes and some sharp peaks rising 
above the general level. The rounded domes are apparently 
covered by local ice-caps while the sharper peaks carry only 
narrow areas of ice in their small valleys. In this part of the
