Route. The observations recorded in this paper were made 
by the writer during the summer of 1896, while a member of 
the Peary expedition to Greenland.* The steamer Hope, 
which carried the party, passed near the land along the entire 
eastern coast of Labrador, and an almost continuous view of 
this coast was obtained. Only one stop was made, ut the 
island of Turnavik, in lat. 55° 15' . A landing was also made 
at Big island, in Hudson's strait, in lat. 63" and long. 71*, 
and several stops on the main Baffin Land coast, just north 
and northeast of Big island. On the return from Greenland, 
a stop was made at Niantilik harbor, on Black Lead island, 
in lat. 65*^, long. 67*^, on the 'south shore of Cumberland 
sound. 
Turnavik Island, Labrador. As seen from the steamer, 
nearly the entire eastern margin of the Labrador peninsula 
has the rounded contour which is so characteristic of glaci- 
ated lands. This is particularly well shown on the hills near 
Turnavlk,which is an island oif tl^e Labrador coast. The eleva- 
tion of Turnavik is only two or three hundred feet in its high- 
est point, and like most of these northern lands, the surface is 
for the most part bare rock, with very little covering except- 
ing in the protected valleys, where, in some places, there is a 
deposit of till, and frequently a covering of peat. The rock is 
a porphyritic gneiss crossed by igneous rocks, and especially 
by diabase dikes. 
Upon Turnavik island signs of glaciation are ever^'^where 
present; the rock surfaces are roches moutonnees forms, with 
very perfect outline, and upon these, glacial grooves and striae 
abound. The perfection with which these delicate scratches 
are preserved in exposed places tells of the recency of the ice 
withdrawal; but perhaps not so much as would at first ap- 
pear. Since the ice left this regit)n, the lower portions of the 
coast have been submerged beneath the sea, and hence for 
*Besides myself, the members of the Cornell party were Prof. A. C. 
Gill, E. M. Kindle, J. O. Martin, T. L. Watson, and J. A. Bonstell. 
Prof. G. II. Barton was with us much of the time in this part of the 
expedition. (See Am. Geol., xviii, 189G, 379.)
