forth beautiful crystalline shoots, as when the first thin delicate ice is just forming in water. A large whale’s case generally yields about five hundred gallons of sperm, though from unavoidable circumstances, considerable of it is spilled, leaks, and dribbles away, or is otherwise irrevocably lost in the ticklish business of securing what you can.
I know not with what fine and costly material the Heidelburgh Tun was coated within, but in superlative richness that coating could not possibly have compared with the silken pearl-coloured membrane, like the lining of a fine pelisse, forming the inner surface of the Sperm Whale’s case.
It will have been seen that the Heidelburgh Tun of the Sperm Whale embraces the entire length of the entire top of the head; and since—as has been elsewhere set forth—the head embraces one third of the whole length of the creature, then setting that length down at eighty feet for a good sized whale, you have more than twenty-six feet for the depth of the tun, when it is lengthwise hoisted up and down against a ship’s side.
As in decapitating the whale, the operator’s instrument is brought close to the spot where an entrance is subsequently forced into the spermaceti magazine; he has, therefore, to be uncommonly heedful, lest a careless, untimely stroke should invade the sanctuary and wastingly let out its invaluable contents. It is this decapitated end of the head, also, which is at last elevated out of the water, and retained in that position by the enormous cutting tackles, whose hempen combinations, on one side, make quite a wilderness of ropes in that quarter.
Thus much being said, attend now, I pray you, to that marvellous and—in this particular instance—almost fatal operation whereby the Sperm Whale’s great Heidelburgh Tun is tapped.
