“The tail is horizontal, from 20 to 30 feet in breadth, indented in the middle, and the two lobes pointed and turned outwards. In it lies the whole strength of the animal. By means of the tail, the whale advances itself in the water with greater or less rapidity; if the motion is slow, the tail cuts the water obliquely, like forcing a boat forward by the operation of sculling; but if the motion is very rapid, it is effected by an undulating motion of the rump.
“The skin in some whales is smooth and shining; in others, it is furrowed, like the water-lines in laid paper, but coarser.
“The colour is black, gray, and white, and a tinge of yellow about the lower parts of the head. The back, upper part of the head, most of the belly, the fins, tail, and part of the under jaw, are deep black. The fore part of the under jaw, and a little of the belly, are white, and the junction of the tail with the body gray. Such are the common colours of the adult whale. I have seen piebald whales. Such whales as are below size are almost entirely of a bluish black colour. The skin of suckers is of a pale bluish colour. The cuticle, or scarf-skin, is no thicker than parchment; the true skin is from three-fourths to an inch in thickness all over the body.
“Immediately beneath the skin lies the blubber, or fat, from 10 to 20 inches in thickness, varying in different parts of the body, as well as in different individuals. The colour, also, is not always the same, being white, red, and yellow; and it also varies in denseness. It is principally for the blubber that the Greenland fishery is carried on. It is cut from the body in large lumps, and carried on board the ship, and then cut into smaller pieces. The fleshy parts, and skin connected with the blubber, are next separated from it, and it is again cut into such pieces as will admit of its being passed into casks by the bung-hole, which is only three or four inches in diameter. In these casks it is conveyed home, where it is boiled in vessels capable of containing from three to six tons, for the purpose of extracting the oil from the fritters, which are tendinous fibres, running in various directions, and containing the oil, or rather connecting together the cellular substance which contains it. These fibres are finest next the skin, thinnest in the middle, and coarsest near the flesh.
“The whales, according to their size, produce from two to twenty tons of oil. The flesh of the young whale is of a fine red colour; that of the old approaches to black, and is coarse, like that of a bull, and is said to be dry and lean when boiled, because there is little fat intermixed with the flesh.
“The food of the whale is generally supposed to consist of different kinds of sepiæ, medusæ, or the clio limacina of Linnæus; but I have great reason to believe, that it is chiefly, if not altogether, of the squill or shrimp tribe; for, on examining the stomach of one of large size, nothing else was found in it; they were about half an inch long, semi-transparent, and of a pale red colour. I also found a great quantity in the mouth of another, having been apparently vomited by it. When the whale feeds, it swims with considerable velocity under water, with its mouth wide open; the water enters by the forepart, but is poured out again at the sides, and the food is entangled and sifted as it were by the whalebone, which does not suffer any thing to escape.
“It seldom remains longer below the surface than twenty to thirty minutes; when it comes up again to blow, it will perhaps remain ten, twenty, or thirty minutes at the surface of the water, when nothing disturbs it. In calm weather, it sometimes sleeps in this situation. It sometimes ascends with so much force, as to leap entirely out of the water; when swimming at its greatest velocity, it moves at the rate of seven to nine miles an hour.
“Its maternal affection deserves notice. The young one is frequently struck for the sake of its mother, which will soon come up close by it, encourage it to swim off, assist it by taking it under its fin, and seldom deserts it while life remains. It is then very dangerous to approach, as she loses all regard for her own safety in anxiety for the preservation of her cub, dashing about most violently, and not dreading to rise even amidst the boats. Except, however, when the whale has young to protect, the male is in general more active and dangerous than the female, especially males of about nine feet bone.”
To the above account of Mr. Scoresby’s, we shall add the following particulars:
The fidelity of whales to each other exceeds whatever we are told even of the constancy of birds. Some fishers, as Anderson informs us, having struck one of two whales, a male and a female, that were in company together, the wounded fish made a long and terrible resistance; it struck down a boat with three men in it, with a single blow of its tail, by which all went to the bottom. The other still attended its companion, and lent it every assistance; till, at last, the fish that was struck sunk under the number of its wounds; while its faithful associate, disdaining to survive the loss, with great bellowing stretched itself upon the dead fish, and shared its fate.
