continued their advance as before, This was in latitude be- 
tween 67° and 69° north; so the sun was visible all the 
twenty-four hours, and we travelled at night so as to have 
his light on our backs. Had we been travelling in the day 
time, we would not have seen one of our little friends, as they 
then hide themselves under the snow or stones. Having 
accidentally lost the small quantity of food we had with us, 
by the man carrying it falling when fording a rapid, our 
chief food for two or three days was these lemmings, which 
we found very good when roasted between two thin slabs 
of limestone, heated by andromeda as fuel. Our three 
dogs also picked up as many as they required. It is well 
known that the lemmings of Norway and Sweden fre- 
quently migrate in immense numbers, but I did not think 
that those of America did so. They are found very far 
north, as they were abundant where the Nares Expedition 
wintered, in latitude 82° north, up Smith’s sound. Here, 
as elsewhere, they formed a considerable portion of the 
food of the white fox. 
That beautiful animal, the arctic hare, has a rather artful 
dodge which it resorts to, evidently with the object of 
throwing his enemies off the scent. After feeding at night 
in the lower grounds, it generally resorts to some higher 
position to lie hid during the day, and the sportsman in 
following his or her track, is surprised to come to a place 
where there are several tracks one over another, causing 
confusion. On going further, he comes to the end of the 
track altogether, the animal having jumped off somewhere ; 
and on retracing his steps, carefully inspecting both sides, 
two little marks are seen in the snow at a distance of 
twenty feet or more from the track, always on the lee side, 
- so that a fox or wolf could not catch the scent. These 
long jumps are repeated three or four times,—the animal 
evidently either using only his hind legs, or putting all 
his four feet close together. Experience soon taught me 
that the hare was in his form at no great distance from 
these “ jumping off” places, and a sharp look-out had to be 
kept, as if you happened to walk directly for him he
