“Both ships' companies were at it next morning rafting water, and made the old hills resound to the chorus of the merry song as they bent back to the tugging oar.” [p.223]

“Large hawsers are then rove through these blocks, then through similar ones, on deck, to the windlass, in the forward part of the ship. To the lower blocks are attached ponderous iron hooks, weighing over one hundred pounds each. These hooks are for the purpose of "hooking on" to the blubber, and can be put on and taken off the blocks at pleasure. And now, suspended in stages over the side, the first and second mates, armed with their long spades, begin cutting a hole in the body for the insertion of the hook just above one of the fins. This done, a broad semicircular line is cut round the hole, the hook is inserted, and the main body of the crew, striking up a wild chorus, now commence heaving at the windlass…..

...The heavers forward now resume their song and their work, and, while the one tackle is peeling and hoisting a second strip from the whale, the other is slowly slackened away, and down goes the first strip through the main hatchway right beneath, into an unfurnished parlor called the “blubberroom.”” [pp.59-61]
