In those waters there are also many of those species of whales which we have already described. It is claimed that there are all sorts of seals, too, in those seas, and that they have a habit of following the ice, as if abundant food would never be wanting there. These are the species of seals that are found there. One is called the “corse seal;” its length is never more than four ells. There is another sort called the “erken-seal,”[222] which grows to a length of five ells or six at the very longest. Then there is a third kind which is called the “flett seal,” which grows to about the same length as those mentioned above. There is still a fourth kind, called the bearded seal, which occasionally grows to a length of six ells or even seven. In addition there are various smaller species, one of which is called the saddleback;[223] it has this name because it does not swim on the belly like other seals but on the back or side; its length is never more than four ells. There remains the smallest kind, which is called the “short seal” and is not more than two ells in length. It has a peculiar nature; for it is reported that these seals can pass under flat ice masses four or even five ells thick and can blow up through them; consequently they can have large openings where-ever they want them. Footnote 222: This is called _haverkn_ in modern Norse and seems to be the same as the grey seal: _Halichoerus gryphus_. See Nansen, _In Northern Mists_, II. 155. Footnote 223: Also called the harp seal: _Phoca Grœnlandica_. There still remains another species which the Greenlanders count among the whales, but which, it seems to me, ought rather to be classed with the seals.[224] These are called walrus and grow to a length of fourteen ells or fifteen at the very highest. In shape this fish resembles the seal both as to hair, head, skin, and the webbed feet behind; it also has the swimming feet in front like the seal. Its flesh like that of other seals must not be eaten on fast days. Its appearance is distinguished from that of other seals in that it has, in addition to the other small teeth, two large and long tusks, which are placed in the front part of the upper jaw and sometimes grow to a length of nearly an ell and a half. Its hide is thick and good to make ropes of; it can be cut into leather strips of such strength that sixty or more men may pull at one rope without breaking it. The seals that we have just discussed are called fish because they find their food in the sea and subsist upon other fishes. They may be freely eaten, though not like the whales, for whale flesh may be eaten on fast days like other fish food, while these fishes may be eaten only on the days when flesh food is allowed. Now I know of nothing else in the waters of Greenland which seems worth mentioning or reporting,—only those things that we have just discussed. Footnote 224: This observation accords with modern scientific classification.
