But with the whale dead, we still had a big problem on our hands. In some way the giant bulk had to be hauled out of the ice. This was a difficult matter even with plenty of time in which to do it. Night was coming on and it was the brig's custom in the hours of darkness to sail far away from the great ice pack with its edging of floating bergs and floes in order to avoid possible accident and to sail back to the whaling grounds on the morrow. This Captain Shorey prepared to do now. As a solution of the dilemma, an empty bread cask or hogshead was brought on deck and the name of the brig was seared in its staves with a hot iron in several places. This cask was towed to the floe, hauled up on the edge of the ice, and the long line of one of the harpoons sticking in the whale was made fast to it by means of staples. Thus the cask marked the floe in which the whale was lying. It was growing dark when the brig went about, said good-night to the whale, and headed for open water to the south. We sailed away before a stiff breeze and soon cask and floe and the great white continent beyond had faded from view. When morning broke we were bowling along under light sail in a choppy sea with nothing but water to be seen in any direction. The great ice cap was somewhere out of sight over the world's northern rim. Not a floe, a berg, or the smallest white chunk of ice floated anywhere in the purple sphere of sea ringed by the wide horizon. Being a green hand, I said to myself, "Good-bye, Mr. Whale, we certainly have seen the last we'll ever see of you." Let me make the situation perfectly clear. Our whale was drifting somewhere about the Arctic Ocean embedded in an ice floe scarcely to be distinguished from a thousand other floes except by a cask upon its margin which at a distance of a few miles would hardly be visible through strong marine glasses. The floe, remember, was not a stationary object whose longitude and latitude could be reckoned certainly, but was being tossed about by the sea and driven by the winds and ocean currents. The brig, on the other hand, had been sailing on the wind without a set course. It had been tacking and wearing from time to time. It, too, had felt the compulsion of the waves and currents. So throughout the night the brig had sailed at random and twenty miles or so away the whale in its floe had been drifting at random. Now how were we going to find our whale again? This struck me that morning on the open sea with neither whale nor ice in sight, as a problem certainly very nice, if not hopeless. The way it was solved was as pretty a feat of navigation as I ever saw. When Captain Shorey came on deck after breakfast, he "shot the sun" through his sextant and went below to make his calculations. In a little while he came on deck again and stepped to the man at the wheel. The helmsman was steering full and by. "How do you head?" asked Captain Shorey. "Northwest," answered the sailor.
