Two men were now told off as “blubber-room men,” whose duty it became to go below, and squeezing themselves in as best they could between the greasy masses of fat, cut it up into “horse-pieces” about eighteen inches long and six inches square.  Doing this they became perfectly saturated with oil, as if they had taken a bath in a tank of it; for as the vessel rolled it was impossible to maintain a footing, and every fall was upon blubber running with oil.  A machine of wonderful construction had been erected on deck in a kind of shallow trough about six feet long by four feet wide and a foot deep.  At some remote period of time it had no doubt been looked upon as a triumph of ingenuity, a patent mincing machine.  Its action was somewhat like that of a chaff-cutter, except that the knife was not attached to the wheel, and only rose and fell, since it was not required to cut right through the “horse-pieces” with which it was fed.  It will be readily understood that in order to get the oil quickly out of the blubber, it needs to be sliced as thin as possible, but for convenience in handling the refuse (which is the only fuel used) it is not chopped up in small pieces, but every “horse-piece” is very deeply scored as it were, leaving a thin strip to hold the slices together.  This then was the order of work.  Two harpooners attended the try-pots, replenishing them with minced blubber from the hopper at the port side, and baling out the sufficiently boiled oil into the great cooling tank on the starboard.  One officer superintended the mincing, another exercised a general supervision over all.  There was no man at the wheel and no look-out, for the vessel was “hove-to” under two close-reefed topsails and fore-topmast-staysail, with the wheel lashed hard down.  A look-out man was unnecessary, since we could not run anybody down, and if anybody ran us down, it would only be because all hands were asleep, for the glare of our try-works fire, to say nothing of the blazing cresset before mentioned, could have been seen for many miles.  So we toiled watch and watch, six hours on and six off, the work never ceasing for an instant night or day.  Though the work was hard and dirty, and the discomfort of being so continually wet through with oil great, there was only one thing dangerous about the whole business.  That was the job of filling and shifting the huge casks of oil.  Some of these were of enormous size, containing 350 gallons when full, and the work of moving them about the greasy deck of a rolling ship was attended with a terrible amount of risk.  For only four men at most could get fair hold of a cask, and when she took it into her silly old hull to start rolling, just as we had got one half-way across the deck, with nothing to grip your feet, and the knowledge that one stumbling man would mean a sudden slide of the ton and a half weight, and a little heap of mangled corpses somewhere in the lee scuppers—­ well one always wanted to be very thankful when the lashings were safely passed.
