winds, however, have been very light. Advance Bluff 
is now shut in by ' Cape Rescue,' the westernmost point 
yet discovered of Cornwallis Island. This shows that 
we are nearing the shore. 
" Toward the north and a little to the west is a per- 
manent dark cloud, a line of stratus with a cumulated 
thickening at the western end. This is the same dur- 
ing sunshine and snow-storm, night and day. It is 
thought by Captain De Haven to he indicative of open 
water. It may he that Cornwallis Island ends there, 
and that this is a continuation of the present channel 
trending to the westward. Or this dark appearance 
may he merely the highland clouds over the mount- 
ains seen on Sunday ; hut De Haven suggests that it 
is rather a vacant space, or water free from ice ; the 
exemption being due to the island and adjacent west- 
ern shore (not more than seven miles from it), acting 
as a barrier to the northern drift of the present chan- 
nel."
