deep-sea fish called “bergylt,’’ which only lives between 
those depths, has been found in his stomach. 
The last and largest of our seals is the gray seal (Hali- 
cherus grypus). We measured one eleven feet long, with 
a girth of eight feet. No doubt, however, larger ones have 
been killed. These seals are practically devoid of hair, 
make the best possible material for covering kayaks, and 
for the manufacture of water-tight feet for boots. The 
skin of the harp seal is used for the legs and for the bottoms 
as well, when the boots are to be used in the coldest weather, 
because this skin is so much softer, and allows freer move- 
ment; but the gray sealskin is much more resistant to 
water. The gray seal is generally shot as he plays along 
the ice edges, but is occasionally meshed in sunken nets.
