some places they almost darken the sea as they rise above water to take breath; they not only 

 seek for prey near the surface, but often descend to the bottom in search of sand-eels and sea- 

 worms, which they root out of the sand with their noses, in the same manner as hogs when 

 suing their food in the field. In fine weather they leap, roll, and tumble in the most joyous 

 manner, principally in the spring and summer, which is supposed to be their pairing season. As 

 they are seen on the surface at such times they appear like black pigs, and hence are often called 

 Hogs and Hog-Fish. They go up the rivers in pursuit of the salmon, as well as other fish. The 

 oil of this Species is of the purest kind. Their flesh is now very rarely eaten among civilized people, 

 but formerly it was esteemed a great delicacy, and all the arts of the cook were lavished upon it for 

 the tables of the great. The Greenlanders quaff the oil and devour the flesh with high relish.
