Upon the end of the “shank” fits the head of the harpoon, known by the names swordfish-iron, lily-iron, and Indian dart. The form of this weapon has undergone much variation. The fundamental idea may very possibly have been derived from the Indian fish-dart, numerous specimens of which are in the National Museum, from various tribes of Indians of New England, British America, and the Pacific. However various the modifications may have been, the similarity of the different shapes is no less noteworthy from the fact that all are peculiarly American. In the enormous collection of fishery implements of all lands at the late exhibition at Berlin, nothing of the kind could be found. What is known to whalers as a toggle-harpoon is a modification of the lily-iron, but so greatly changed by the addition of a pivot by which the head of the harpoon is fastened to the shank that it can hardly be regarded as the same weapon. The lily-iron is, in principle, exactly what a whaleman would describe by the word “toggle.” It consists of a two-pointed piece of metal, having in the center, at one side, a ring or socket the axis of which is parallel with the long diameter of the implement. In this is inserted the end of the pole-shank, and to it or near it is also attached the harpoon-line. When the iron has once been thrust point first through some solid substance, such as the side of a fish, and is released upon the other side by the withdrawal of the pole from the socket, it is free, and at once turns its long axis at right angle to the direction in which the harpoon-line is pulling, and this is absolutely prevented from withdrawal. The principle of the whale harpoon or toggle-iron is similar, except that the pole is not withdrawn, and the head, turning upon a pivot at its end, fastens the pole itself securely to the fish, the harpoon-line being attached to some part of the pole. The swordfish lily-iron head, as now ordinarily used, is about four inches in length, and consists of two lanceolate blades, each about an inch and a half long, connected by a central piece much thicker than they, in which, upon one side, and next to the flat side of the blade, is the socket for the insertion of the pole-shank. In this same central enlargement is forged an opening to which the harpoon-line is attached. The dart-head is usually made of steel; sometimes of iron, which is generally galvanized; sometimes of brass.
The entire weight of the harpoon—pole, shank, and head—should not exceed eighteen pounds.
The harpoon-line is from fifty to one hundred and fifty fathoms long, and is ordinarily what is known as “fifteen-thread line.” At the end is sometimes fastened a buoy, and an ordinary mackerel-keg is generally used for this purpose.
In addition to the harpoon every swordfish fisherman carries a lance. This implement is precisely similar to a whaleman’s lance, except that it is smaller, consisting of a lanceolate blade perhaps one inch wide and two inches long, upon the end of a shank of five-eighths-inch iron, perhaps two or three feet in length, fastened in the ordinary way upon a pole fifteen to eighteen feet in length.
The swordfish are always harpooned from the end of the bowsprit of a sailing-vessel. It is next to impossible to approach them in a small boat. All vessels regularly engaged in this fishery are supplied with a special apparatus called a “rest,” or “pulpit,” for the support of the harpooner as he stands on the bowsprit, and this is almost essential to success, although it is possible for an active man to harpoon a fish from this station without the aid of the ordinary framework. Not only the professional swordfish fisherman, but many mackerel-schooners and packets are supplied in this manner.
The swordfish never comes to the surface except in moderate, smooth weather. A vessel cruising in search of them proceeds to the fishing-ground, and cruises hither and thither wherever the abundance of small fish indicates that they ought to be found. Vessels which are met are hailed and asked whether any swordfish have been seen, and if tidings are thus obtained the ship’s course is at once laid for the locality where they were last noticed. A man is always stationed at the masthead, where, with the keen eye which practice has given him, he can easily descry the telltale dorsal fins at a distance of two or three miles. When a fish has once been sighted, the watch “sings out,” and the vessel is steered directly toward it. The skipper takes his place in the “pulpit” holding the pole in both hands by the small end, and directing the man at the wheel by voice and gesture how to steer. There is no difficulty in approaching the fish with a large vessel, although, as has already been remarked, they will not suffer a small boat to come near them. The vessel plows and swashes through the water, plunging its bowsprit into the waves without exciting their fears. Noises frighten them and drive them down. Although there would be no difficulty in bringing the end of a bowsprit directly over the fish, a skilful harpooner never waits for this. When the fish is from six to ten feet in front of the vessel it is struck. The harpoon is never thrown, the pole being too long. The strong arm of the harpooner punches the dart into the back of the fish, right at the side of the high dorsal fin, and the pole is withdrawn and fastened again to its place. When the dart has been fastened to the fish the line is allowed to run out as far as the fish will carry it, and is then passed in a small boat, which is towing at the stern. Two men jump into this, and pull in upon the line until the fish is brought in alongside; it is then killed with a whale-lance or a whale-spade, which is stuck into the gills.
The fish having been killed, it is lifted upon the deck by a purchase tackle of two double blocks rigged in the shrouds.
The pursuit of the swordfish is much more exciting than ordinary fishing, for it resembles the hunting of large animals upon the land and partakes more of the nature of the chase. There is no slow and careful baiting and patient waiting, and no disappointment caused by the accidental capture of worthless “bait-stealers.” The game is seen and followed, and outwitted by wary tactics, and killed by strength of arm and skill. The swordfish is a powerful antagonist sometimes, and sends his pursuers’ vessel into harbor leaking, and almost sinking, from injuries he has inflicted. I have known a vessel to be struck by wounded swordfish as many as twenty times in a season. There is even the spice of personal danger to savor the chase, for the men are occasionally wounded by the infuriated fish. One of Captain Ashby’s crew was severely wounded by a swordfish which thrust his beak through the oak floor of a boat on which he was standing, and penetrated about two inches in his naked heel. The strange fascination draws men to this pursuit when they have once learned its charms. An old swordfish fisherman, who had followed the pursuit for twenty years, told me that when he was on the cruising-ground, he fished all night in his dreams, and that many a time he has rubbed the skin off his knuckles by striking them against the ceiling of his bunk when he raised his arms to thrust the harpoon into visionary monster swordfishes.
The Spear-fish or Bill-fish
The bill-fish or spear-fish, Tetrapturus indicus (with various related forms, which may or may not be specifically identical), occurs in the western Atlantic from the West Indies (latitude 10° to 20° N.) to southern England (latitude 40° N.); in the eastern Atlantic, from Gibraltar (latitude 45° N.) to the Cape of Good Hope (latitude 30° S.) in the Indian Ocean, the Malay Archipelago, New Zealand (latitude 40° S.), and on the west coast of Chile and Peru. In a general way, the range is between latitude 40° N. and latitude 40° S.
