Jones Sound, increasingly so with increasing distance to the 
west. Forty miles orso from the entrance, navigation became 
difficult. South of Jones Sound, little ice was encountered until 
latitude 72° 30’ was reached. Here it became more plentiful, 
and further south, in latitude 71° or thereabouts, a very extensive 
pack was encountered, the east-west extent of which could have 
been little less than 200 miles. Its extension southward was not 
determined, but southwest of Disco, in latitude 66° 30’, the east 
edge of a considerable pack was touched, which may have been 
continuous northward with that which had been encountered in 
latitude 71°. If so, the north-south diameter of the pack must 
have been as much as 300 miles. 
L:vidences concerning recent changes of level. On the whole, the 
evidence gathered concerning recent changes of level along the 
northern coasts is rather meager. This is not to be interpreted 
as meaning that such evidence is necessarily wanting, but merely 
that it is not usually so obtrusive as to be detected upon cursory 
inspection. Even the absence of topographic evidences of 
changes of level would not necessarily mean that such changes 
have not taken place. The study of the coastal lands here, as 
elsewhere, led to the conviction that a region may be submerged 
and reélevated, without preserving very distinct topographic 
evidence of the change. 
The topography of most of the land front seen, both on 
Greenland and on the continent, is without any notable horizontal 
clement that is tertaces, beaches, ete. presentuat ally are 
generally, though not always, so inconspicuous that they were 
not detected in passing, even when the course was so close to 
the coast as to afford excellent opportunity for studying the 
details of its topography. 
At Jakobshayn stria were seen on the gneiss down virtually 
to the level of the water. Their presence at this low level is 
perhaps not especially significant so far as changes of level are 
concerned. If the land has risen since they were formed, the 
shore line probably did not remain long at the level at which 
they occur. Their presence at the sea level, and at all higher
