The first effort of a "fast-fish," or whale that has been struck, is to escape from the boat by sinking under water. After this, it pursues its course downward, or reappears at a little distance, and swims with great celerity, near the surface of the water. It sometimes returns instantly to the surface, and gives evidence of its agony by the most convulsive throes. The downward course of a whale is, however, the most common. A whale, struck near the edge of any large sheet of ice, and passing underneath it, will sometimes run the whole of the lines out of one boat. The approaching distress of a boat, for want of line, is indicated by the elevation of an oar, to which is added a second, a third, or even a fourth, in proportion to the nature of the exigence. The utmost care and attention are requisite, on the part of every person in the boat, when the lines are running out; fatal consequences having been sometimes produced by the most trifling neglect.--When the line happens to "run foul," and cannot be cleared on the instant, it sometimes draws the boat under water; on which, if no auxiliary boat, or convenient piece of ice, be at hand, the crew are plunged into the sea, and are obliged to trust to their oars or their skill in swimming, for supporting themselves on the surface. Captain Scoresby relates an accident of this kind, which happened on his first voyage to the whale fishery. A thousand fathoms of line were already out, and the fast-boat was forcibly pressed against the side of a piece of ice. The harpooner, in his anxiety to retard the flight of the whale, applied too many turns of the line round the bollard, which, getting entangled, drew the boat beneath the ice. Another boat, providentially was at hand, into which the crew had just time to escape. The whale, with near two miles length of line, was, in consequence of the accident, lost, but the boat was recovered. The average stay under water of a wounded whale is about thirty minutes. When it reappears, the assisting boats make for the place with their utmost speed, and as they reach it, each harpooner plunges his harpoon into its back, to the amount of three, four, or more, according to the size of the whale. It is then actively plied with lances, which are thrust into its body, aiming at its vitals. The sea to a great extent around is dyed with its blood, and the noise made by its tail in its dying struggle, may be heard several miles. In dying, it turns on its back or on its side; which circumstance is announced by the capturers with the striking of their flags, accompanied with three lively huzzas!
