Whales are sometimes captured, with a single harpoon, in the space of fifteen minutes. Sometimes they resist forty or fifty hours, and at times they will break three or four lines at once, or tear themselves clear off the harpoons, by the violence of their struggles. Generally the capture of a whale depends on the activity of the harpooner, the state of the wind and weather, or the peculiar conduct of the animal itself. Under the most favourable circumstances, the length of time does not exceed an hour. The general average may be stated at two hours. Instances have occurred where whales have been taken without being struck at all, simply by entangling themselves in the lines that had been used to destroy others, and struggling till they were drowned or died of exhaustion. The fishery for whales, when conducted at the margin of those wonderful sheets of ice, called fields, is, when the weather is fine, and the refuge for ships secure, the most agreeable, and sometimes the most productive of all other ways. When the fish can be observed "blowing" in any of the holes of a field, the men travel over the ice and attack it with lances to turn it back. As connected with this subject, Captain Scoresby relates the following circumstance, which occurred under his own observation. On the eighth of July, 1813, the ship Esk lay by the edge of a large sheet of ice, in which there were several thin parts, and some holes. Here a whale being heard blowing, a harpoon, with a line fastened to it, was conveyed across the ice, from a boat on guard, and the harpooner succeeded in striking the whale, at the distance of three hundred and fifty yards from the verge. It dragged out ten lines, (2400 yards,) and was supposed to be seen blowing in different holes in the ice. After some time it made its appearance on the exterior, and was again struck, at the moment it was about to go under the second time. About an hundred yards from the edge, it broke the ice where it was a foot thick, with its head, and respired through the opening. It then pushed forward, breaking the ice as it advanced, in spite of the lances constantly directed against it. At last it reached a kind of basin in the field, where it floated on the surface without any incumbrance from ice. Its back being fairly exposed, the harpoon struck from the boat on the outside, was observed to be so slightly entangled, that it was ready to drop out. Some of the officers lamented this circumstance, and wished that the harpoon might be better fast; at the same time observing that if it should slip out, either the fish would be lost, or they should be under the necessity of flensing it where it lay, and of dragging the blubber over the ice to the ship; a kind and degree of labor every one was anxious to avoid. No sooner was the wish expressed, and its importance explained, than a young and daring sailor stepped forward, and offered to strike the harpoon deeper. Not at all intimidated by the surprise manifested
