All whale-boats carry certain curious contrivances, originally invented by the Nantucket Indians, called druggs.  Two thick squares of wood of equal size are stoutly clenched together, so that they cross each other’s grain at right angles; a line of considerable length is then attached to the middle of this block, and the other end of the line being looped, it can in a moment be fastened to a harpoon.  It is chiefly among gallied whales that this drugg is used.  For then, more whales are close round you than you can possibly chase at one time.  But sperm whales are not every day encountered; while you may, then, you must kill all you can.  And if you cannot kill them all at once, you must wing them, so that they can be afterwards killed at your leisure.  Hence it is, that at times like these the drug, comes into requisition.  Our boat was furnished with three of them.  The first and second were successfully darted, and we saw the whales staggeringly running off, fettered by the enormous sidelong resistance of the towing drugg.  They were cramped like malefactors with the chain and ball.  But upon flinging the third, in the act of tossing overboard the clumsy wooden block, it caught under one of the seats of the boat, and in an instant tore it out and carried it away, dropping the oarsman in the boat’s bottom as the seat slid from under him.  On both sides the sea came in at the wounded planks, but we stuffed two or three drawers and shirts in, and so stopped the leaks for the time.

It had been next to impossible to dart these drugged-harpoons, were it not that as we advanced into the herd, our whale’s way greatly diminished; moreover, that as we went still further and further from the circumference of commotion, the direful disorders seemed waning.  So that when at last the jerking harpoon drew out, and the towing whale sideways vanished; then, with the tapering force of his parting momentum, we glided between two whales into the innermost heart of the shoal, as if from some mountain torrent we had slid into a serene valley lake.  Here the storms in the roaring glens between the outermost whales, were heard but not felt.  In this central expanse the sea presented that smooth satin-like surface, called a sleek, produced by the subtle moisture thrown off by the whale in his more quiet moods.  Yes, we were now in that enchanted calm which they say lurks at the heart of every commotion.  And still in the distracted distance we beheld the tumults of the outer concentric circles, and saw successive pods of whales, eight or ten in each, swiftly going round and round, like multiplied spans of horses in a ring; and so closely shoulder to shoulder, that a Titanic circus-rider might easily have over-arched the middle ones, and so have gone round on their backs.  Owing to the density of the crowd of reposing whales, more immediately surrounding the embayed axis of the herd, no possible chance of escape was at present afforded us.  We must watch for a breach in the living wall that hemmed us in; the wall that had only admitted us in order to shut us up.  Keeping at the centre of the lake, we were occasionally visited by small tame cows and calves; the women and children of this routed host.
