Tun

Nimble as a cat, Tashtego mounts aloft; and without altering his erect posture, runs straight out upon the overhanging mainyard-arm, to the part where it exactly projects over the hoisted Tun. He has carried with him a light tackle called a whip, consisting of only two parts, travelling through a single-sheaved block. Securing this block, so that it hangs down from the yard-arm, he swings one end of the rope, till it is caught and firmly held by a hand on deck.

Inserting this pole into the bucket, Tashtego downward guides the bucket into the Tun, till it entirely disappears; then giving the word to the seamen at the whip, up comes the bucket again, all bubbling like a dairy-maid’s pail of new milk. Carefully lowered from its height, the full-freighted vessel is caught by an appointed hand, and quickly emptied into a large tub. Then remounting aloft, it again goes through the same round until the deep cistern will yield no more.
