extent. The promontories are closely .girt about by ice on 
their sides and in the rear, and lack only enclosure on the sea 
face to reduce them to typical nunataks. Indeed, many of the 
prominences that lie a little back from the coast are thus com- 
pletely surrounded, and present excellent types of islands in the 
ice, the Greenlander’s nunataks. 
From a vessel sailing some distance off the shore (and the 
broad foot of stationary bay ice rarely gives a ship any other 
privilege), a considerable tract of the upper slope of the glacier 
is visible. The sky line lies some miles inland. Only a few of 
the promontories on the coast rise high enough to be projected 
across this sky line and interrupt the otherwise continuous stretch 
of the glacial horizon. The ice does not meet the sky in a 
simple straight line. It undulates gently, indicating some notable 
departure of the upper surface of the ice tract from a plane. As 
the ice-field slopes down from the interior to the border of the 
bay, it takes on a still more pronounced undulatory surface. It 
is not unlike some of our gracefully rolling prairies as they 
descend from uplands to valleys, when near their middle-life 
development. The convexities are much broken by crevasses. It 
is not a few gaping fissures here and there, or even at regular inter- 
vals, but an intimate cracking open of the whole convex surface, 
so as to alter its entire expression. Asa result, the light reflected 
from the crevassed portions is brighter than that from the 
smoother parts, and the undulations are thus set forth delicately 
Eut very expressively by the varying tones of the nearly white 
light. The intimacy and extent of the crevassing on the swell- 
ing surfaces is quite remarkable when the relative slightness of 
their convexities, the breadth and freedom cf the sheet, and the 
evident slowness of motion are considered. The slowness of 
motion is safely inferred from the limited amount of surface 
wastage during the short season, and the very moderate iceberg 
product in proportion to the vast frontage. The undulations are 
undoubtedly due to the inequalities of the rock surface below. 
The first impression is that the ice sheet is quite thin and alto- 
gether subservient to the basal irregularities. And this is doubt-
