DALY: GEOLOGY OF THE NORTHEAST COAST OF LABRADOR. 237 
light of their effects on the existing topography. Among the incentives 
which the writer had to join the expedition was the need of more detailed | 
observations than had yet been made on the general direction of ice-move- 
ment in glacial times ; on the question of the non-glaciation of the high 
northern mountains ; and on the “lunoid furrows” that were long ago 
found on the coast by Packard. The amount and character of post- 
glacial uplift, the elevated beaches and other shore-forms associated with 
that emergence likewise invited as close study as time and circum- 
stances would permit. 
GiactaL Markines ; Direction or Ice-MovEMENT. 
Several visitors to the coast have repeatedly emphasized the difficulty 
of discovering there the glacial striz and grooves which should normally 
appear on ledges so strongly ice-worn as those of Labrador. For this 
reason, it had been anticipated that our necessarily short halts at the dif- 
ferent anchorages would not permit of our adding many localities to the 
few where the course of ice-movement has been determined. It was there- 
fore an agreeable surprise to find ice-markings at nearly every landing 
place and often in great abundance. ‘The intense power of the frost has, 
in postglacial time, certainly caused some obliteration of such records ; 
but the non-discovery of these is much more likely to have been occa- 
sioned by the fact that search seems to have béen hitherto largely con- 
fined to the shore-zone recently emerged from the sea. The evidence 
and amount of this emergence will be considered in the sequel. In the 
southern part of the coastal belt, it is only the higher points which, dur- 
ing the maximum postglacial depression of the land, remained above the 
sea. As the land arose, wave-action, coast-ice and the exceptional power 
of frost in the zone of flying spray, have tended to cause the destruction 
of all glacial marks within the belt of land thus exposed. 
Selected readings of the directions followed by glacial striation are 
given in the following table (Table II.), and are plotted on the map. 
(Plate 13.) It will be seen that at all elevations, both in the valleys 
and on the hill-tops, the ice-movement was outward from the central 
part of the peninsula. The result is to confirm the conclusion which 
has been based on five recorded single observations made at Hamilton 
Inlet, Indian Island, Davis Inlet, Nain, and Nachvak.
