sperm whale-line measures something over two hundred fathoms. Towards the stern of the boat it is spirally coiled away in the tub, not like the worm-pipe of a still though, but so as to form one round, cheese-shaped mass of densely bedded “sheaves,” or layers of concentric spiralizations, without any hollow but the “heart,” or minute vertical tube formed at the axis of the cheese. As the least tangle or kink in the coiling would, in running out, infallibly take somebody’s arm, leg, or entire body off, the utmost precaution is used in stowing the line in its tub. Some harpooneers will consume almost an entire morning in this business, carrying the line high aloft and then reeving it downwards through a block towards the tub, so as in the act of coiling to free it from all possible wrinkles and twists.
In the English boats two tubs are used instead of one; the same line being continuously coiled in both tubs. There is some advantage in this; because these twin-tubs being so small they fit more readily into the boat, and do not strain it so much; whereas, the American tub, nearly three feet in diameter and of proportionate depth, makes a rather bulky freight for a craft whose planks are but one half-inch in thickness; for the bottom of the whale-boat is like critical ice, which will bear up a considerable distributed weight, but not very much of a concentrated one. When the painted canvas cover is clapped on the American line-tub, the boat looks as if it were pulling off with a prodigious great wedding-cake to present to the whales.
Both ends of the line are exposed; the lower end terminating in an eye-splice or loop coming up from the bottom against the side of the tub, and hanging over its edge completely disengaged from everything. This arrangement of the lower end is necessary on two accounts. First: In order to facilitate the fastening to it of an additional line from a neighboring boat, in case the stricken whale should sound so deep as to threaten to carry off the entire line originally attached to the harpoon. In these instances, the whale of course is shifted like
