The swordfish, Xiphias gladius, ranges along the Atlantic coast of America from Jamaica (latitude 18° N.), Cuba, and the Bermudas, to Cape Breton (latitude 47° N.). It has not been seen at Greenland, Iceland, or Spitzbergen, but occurs, according to Collett, at the North Cape (latitude 71°). It is abundant along the coasts of western Europe, entering the Baltic and the Mediterranean. I can find no record of the species on the west coast of Africa south of Cape Verde, though Lutken, who may have access to facts unknown to me, states that they occur clear down to the Cape of Good Hope, South Atlantic in mid-ocean, to the west coast of South America and to southern California (latitude 34°), New Zealand, and in the Indian Ocean off Mauritius.

The names of the swordfish all have reference to that prominent feature, the prolonged snout. The “swordfish” of our own tongue, the “zwardfis” of the Hollander, the Italian “sofia” and “pesce-spada,” the Spanish “espada” and “espadarte,” varied by “pez do spada” in Cuba, and the French “espadon,” “dard,” and “epee de mer,” are simply variations of one theme, repetitions of the “gladius” of ancient Italy and “xiphius,” the name by which Aristotle, the father of zoology, called the same fish twenty-three hundred years ago. The French “empereur” and the “imperador” and the “ocean kingfish” of the Spanish and French West Indies, carry out the same idea, for the Roman Emperor was always represented holding a drawn sword in his hand. The Portuguese names are “aguhao,” meaning “needle,” or “needle-fish.”

This species has been particularly fortunate in escaping the numerous redescriptions to which almost all widely distributed forms have been subjected. By the writers of antiquity it was spoken of under its Aristotelian name, and in the tenth edition of his Systema NaturÆ, at the very inception of binomial nomenclative, Linnaeus called it Xiphias gladius. By this name it has been known ever since, and only one additional name is included in its synonym, Xiphias rondeletic of Leach.

The swordfish has been so long and so well known that its right to its peculiar name has seldom been infringed upon. The various species of Tetrapturus have sometimes shared its title, and this is not to be wondered at, since they closely resemble Xiphias gladius, and the appellative has frequently been applied to the family XiphiidÆ—the swordfish—which includes them all.

The name “bill-fish,” usually applied to our Tetrapturus albidus, a fish of the swordfish family, often taken on our coast, must be pronounced objectionable, since it is in many districts used for various species of BelonidÆ, the garfishes or green-bones (Belone truncata and others), which are members of the same faunas. Spear-fish is a much better name.

The “sailfish,” Histiophorus americanus, is called by sailors in the South the “boohoo” or “woohoo.” This is evidently a corrupted form of “guebum,” a name, apparently of Indian origin, given to the same fish in Brazil. It is possible that Tetrapturus is also called “boohoo,” since the two genera are not sufficiently unlike to impress sailors with their differences. Blecker states that in Sumatra the Malays call the related species, H. gladius, by the name “Joohoo” (Juhu), a curious coincidence. The names may have been carried from the Malay Archipelago to South America, or vice versa, by mariners.

In Cuba the spear-fish are called “aguja” and “aguja de palada”; the sailfish, “aguja prieta” or “aguja valadora”; Tetrapturus albidus especially known as the “aguja blanca,” T. albidus as the “aguja de castro.”

In the West Indies and Florida the scabbard-fish or silvery hairy-tail, Trichiurus lepturus, a form allied to the Xiphias, though not resembling it closely in external appearance, is often called “swordfish.” The body of this fish is shaped like the blade of a saber, and its skin has a bright, metallic luster like that of polished steel, hence the name.

Swordfish are most abundant on the shoals near the shore and on the banks during the months of July and August; that they make their appearance on the frequented cruising-grounds between Montauk Point and the eastern part of Georges Banks sometime between the 25th of May and the 20th of June, and that they remain until the approach of cold weather in October and November. The dates of the first fish on the cruising-grounds referred to are recorded for three years, and are reasonably reliable: in 1875, June 20th; in 1877, June 10th; in 1878, June 14th.

South of the cruising-grounds the dates of arrival and departure are doubtless farther apart, the season being shorter north and east. There are no means of obtaining information, since the men engaged in this fishery are the only ones likely to remember the dates when the fish are seen.

The swordfish comes into our waters in pursuit of its food. At least this is the most probable explanation of its movements, since the duties of reproduction appear to be performed elsewhere. Like the tuna, the bluefish, the bonito, and the squiteague, they pursue and prey upon the schools of menhaden and mackerel, which are so abundant in the summer months. “When you see swordfish, you may know that mackerel are about,” said an old fisherman to me. “When you see the fin-back whale following food, there you may find swordfish,” said another. The swordfish also feeds upon squid, which are at times abundant on our banks.

To what extent this fish is amenable to the influences of temperature is an unsolved problem. We are met at the outset by the fact that they are frequently taken on trawl lines which are set at the depth of one hundred fathoms or more, on the offshore banks. We know that the temperature of the water in these localities and at that depth is sure to be less than 40° Fahr. How is this fact to be reconciled with the known habits of the fish, that it prefers the warmest weather of summer and swims at the surface in water of temperature ranging from 55° to 70°, sinking when cool winds blow below? The case seemed clear enough until the inconvenient discovery was made that swordfish are taken on bottom trawl lines. In other respects their habits agree closely with those of the mackerel tribe, all the members of which seem sensitive to slight changes in temperature, and which, as a rule, prefer temperature in the neighborhood of 50° or more.

The appearance of the fish at the surface depends largely upon the temperature. They are seen only upon quiet summer days, in the morning before ten or eleven o’clock, and in the afternoon about four o’clock. Old fishermen say that they rise when the mackerel rise, and when the mackerel go down they go down also.

Regarding the winter abode of the swordfish, conjecture is useless. I have already discussed this question at length with reference to the menhaden and mackerel. With the swordfish the conditions are very different. The former are known to spawn in our waters, and the schools of young ones follow the old ones in toward the shores. The latter do not spawn in our waters. We cannot well believe that they hibernate, nor is the hypothesis of a sojourn in the middle strata of mid-ocean exactly tenable. Perhaps they migrate to some distant region, where they spawn. But then the spawning-time of this species in the Mediterranean, as is related in a subsequent paragraph, appears to occur in the summer months, at the very time when the swordfish are most abundant in our own waters, apparently feeling no responsibility for the perpetuation of their species.

The swordfish, when swimming at the surface, usually allows its dorsal fin and the upper lobe of its caudal fin to be visible, projecting out of the water. It is this habit which enables the fisherman to detect the presence of the fish. It swims slowly along, and the fishing-schooner with a light breeze finds no difficulty in overtaking it. When excited its motions are very rapid and nervous. Swordfish are sometimes seen to leap entirely out of the water. Early writers attributed this habit to the tormenting presence of parasites, but this theory seems hardly necessary, knowing what we do of its violent exertions at other times. The pointed head, the fins of the back and abdomen snugly fitting into grooves, the absence of ventrals, the long, lithe, muscular body, sloping slowly to the tail, fits it for the most rapid and forceful movement through the water. Prof. Richard Owen, testifying in an England court in regard to its power, said:

Many very curious instances are on record of the encounter of this fish with other fishes, or of their attacks upon ships. What can be the inducement for it to attack objects so much larger than itself is hard to surmise. We are all familiar with the couplet from Oppian:

It surely seems as if temporary insanity sometimes takes possession of the fish. It is not strange that when harpooned it should retaliate by attacking its assailant. An old swordfisherman told Mr. Blackman that his vessel had been struck twenty times. There are, however, many instances of entirely unprovoked assaults on vessels at sea. Many of these are recounted in a later portion of this memoir. Their movements when feeding are discussed below as well as their alleged peculiarities of movement during breeding season.

It is the universal testimony of our fishermen that two are never seen swimming close together. Captain Ashby says that they are always distant from each other at least thirty or forty feet.

The pugnacity of the swordfish has become a byword. Without any special effort on my part, numerous instances of their attacks upon vessels have in the last ten years found their way into the pigeonhole labeled “Swordfish.”

Ælian says (b. XXXII, c. 6) that the swordfish has a sharp-pointed snout with which it is able to pierce the sides of a ship and send it to the bottom, instances of which have been known near a place in Mauritania known as Cotte, not far from the river Sixus, on the African side of the Mediterranean. He describes the sword as like the beak of the ship known as the trireme, which was rowed with three banks of oars.

The London Daily News of December 11, 1868, contained the following paragraph, which emanated, I suspect, from the pen of Prof. R. A. Proctor.

The food of the swordfish is of a very mixed nature.

Doctor Fleming found the remains of sepias in its stomach, and also small fishes. Oppian stated that it eagerly devours the Hippuris (probably CoryphÆna). A specimen taken off Saconnet July 22, 1875, had in its stomach the remains of small fish, perhaps Stromateus triacanthus, and jaws of a squid, perhaps Loligo pealin. Their food in the western Atlantic consists for the most part of the common schooling species of fishes. They feed on menhaden, mackerel, bonitoes, bluefish, and other species which swim in close schools. Their habits of feeding have often been described to me by old fishermen. They are said to rise beneath the school of small fish, striking to the right and left with their swords until they have killed a number, which they then proceed to devour. Menhaden have been seen floating at the surface which have been cut nearly in twain by a blow of a sword. Mr. John H. Thompson remarks that he has seen them apparently throw the fish in the air, catching them on the fall.

Capt. Benjamin Ashby says that they feed on mackerel, herring, whiting, and menhaden. He has found half a bucketful of small fish of these kind in the stomach of one swordfish. He has seen them in the act of feeding. They rise perpendicularly out of the water until the sword and two-thirds of the remainder of the body are exposed to view. He has seen a school of herring at the surface on Georges Banks as closely as they could be packed. A swordfish came up through the dense mass and fell flat on its side, striking many fish with the sides of its sword. He has at one time picked up as much as a bushel of herrings thus killed by a swordfish on Georges Banks.

But little is known regarding their time and place of breeding. They are said to deposit their eggs in large quantities on the coasts of Sicily, and European writers give their spawning-time occurring the latter part of spring and the beginning of summer. In the Mediterranean they occur of all sizes from four hundred pounds down, and the young are so plentiful as to become a common article of food.

M. Raymond, who brought to Cuvier a specimen of aistiophorn four inches long, taken in January, 1829, in the Atlantic, between the Cape of Good Hope and France, reported that there were good numbers of young sailfish in the place where this was taken.

Meunier, quoting Spollongain, states that the swordfish does not approach the coast of Sicily except in the season of reproduction; the males are then seen pursuing the females. It is a good time to capture them, for when the female has been taken the male lingers near and is easily approached. The fish are abundant in the Straits of Messina from the middle of April to the middle of September; early in the season they hug the Calabrian shore, approaching from the north; after the end of June they are most abundant on the Sicilian shore, approaching from the south.

From other circumstances, it seems certain that there are spawning-grounds in the seas near Sicily and Genoa, for from November to the 1st of March young ones are taken in the Straits of Messina, ranging in weight from half a pound to twelve pounds.

In the Mediterranean, as has been already stated, the young fish are found from November to March, and here from July to the middle of September the male fish are seen pursuing the female over the shoals, and at this time the males are easily taken. Old swordfish fishermen, Captain Ashby and Captain Kirby, assure me that on our coast, out of thousands of specimens they have taken, they have never seen one containing eggs. I have myself dissected several males, none of which were near breeding-time. In the European waters they are said often to be seen swimming in pairs, male and female. Many sentimental stories were current, especially among the old writers, concerning the conjugal affection and unselfish devotion of the swordfish, but they seem to have originated in the imaginative brain of the naturalist rather than in his perceptive faculties. It is said that when the female fish is taken the male seems devoid of fear, approaches the boat, and allows himself easily to be taken, but if this be true, it appears to be the case only in the height of the breeding season, and is easily understood. I cannot learn that two swordfish have ever been seen associated together in our waters, though I have made frequent and diligent inquiry.

There is no inherent improbability, however, in this story regarding the swordfish in Europe, for the same thing is stated by Professor Poey as the result upon the habits of Tetrapturus.

The only individual of which we have the exact measurements was taken off Saconnet, Rhode Island, July 23, 1874. This was seven feet seven inches long, weighing one hundred and thirteen pounds. Another, taken off No Man’s Land, July 20, 1875, and cast in plaster for the collection of the National Museum, weighed one hundred and twenty pounds and measured about seven feet. Another, taken off Portland, August 15, 1878, was 3,999 millimeters long and weighed about six hundred pounds. Many of these fish doubtless attain the weight of four and five hundred pounds, and some perhaps grow to six hundred; but after this limit is reached, I am inclined to believe larger fish are exceptional. Newspapers are fond of recording the occurrence of giant fish, weighing one thousand pounds and upward, and old sailors will in good faith describe the enormous fish which they saw at sea, but could not capture; but one well-authenticated instance of accurate weighing is much more valuable. The largest one ever taken by Capt. Benjamin Ashby, for twenty years a swordfish fisherman, was killed on the shoals back of Edgartown, Massachusetts. When salted it weighed six hundred and thirty-nine pounds. Its live weight must have been as much as seven hundred and fifty or eight hundred. Its sword measured nearly six feet. This was an extraordinary fish among the three hundred or more taken by Captain Ashby in his long experience. He considers the average size to be about two hundred and fifty pounds dressed, or five hundred and twenty-five alive. Captain Martin, of Gloucester, estimated the average size at three to four hundred pounds. The largest known to Captain Michaux weighed six hundred and twenty-eight. The average about Block Island he considers to be two hundred pounds.

The size of the smallest swordfish taken on our eastern coast is a subject of much deeper interest, for it throws light on the time and place of breeding. There is some difference of testimony regarding the average size, but all fishermen with whom I have talked agree that very small ones do not find their way into our shore waters. Numerous very small specimens have, however, been already taken by the Fish Commission at sea, off our middle and southern coast.

Capt. John Rowe has seen one which did not weigh more than seventy-five pounds when taken out of the water.

Capt. R. H. Hurlbert killed near Block Island, in July, 1877, one which weighed fifty pounds and measured about two feet without its sword.

Captain Ashby’s smallest weighed about twenty-five pounds when dressed; this he killed off No Man’s Land. He tells me that a Bridgeport smack had one weighing sixteen pounds (or probably twenty-four when alive), and measuring eighteen inches without its sword.

In August, 1878, a small specimen of the mackerel-shark, Lamna cornubica, was captured at the mouth of Gloucester Harbor. In its nostril was sticking a sword, about three inches long, of a young swordfish. When this was pulled out the blood flowed freely, indicating that the wound was recent. The fish to which this sword belonged cannot have exceeded ten or twelve inches in length. Whether the small swordfish met with its misfortune in our waters, or whether the shark brought this trophy from beyond the sea, is an unsolved problem.

Lutken speaks of a very young individual taken in the Atlantic, latitude 32° 50' N., 74° 19' W. This must be about one hundred and fifty miles southeast of Cape Hatteras.

For many years from three to six hundred of these fish have been taken annually on the New England coast. It is not unusual for twenty-five or more to be seen in the course of a single day’s cruising, and sometimes as many as this are visible from the masthead at one time. Captain Ashby saw twenty at one time, in August, 1889, between Georges Banks and the South Shoals. One Gloucester schooner, Midnight, Capt. Alfred Wixom, took fourteen in one day on Georges Banks in 1877.

Capt. John Rowe obtained twenty barrels, or four thousand pounds, of salt fish on one trip to Georges Banks; this amount represents twenty fish or more. Captain Ashby has killed one hundred and eight swordfish in one year; Capt. M. C. Tripp killed about ninety in 1874.

Such instances as these indicate in a general way the abundance of the swordfish. A vessel cruising within fifty miles of our coast, between Cape May and Cape Sable, during the months of June, July, August, and September, cannot fail, on a favorable day, to come in sight of several of them. Mr. Earll states that the fishermen of Portland never knew them more abundant than in 1879. This is probably due in part to the fact that the fishery there is of a very recent origin.There is no evidence of any change in their abundance, either increase or decrease. Fishermen agree that they are as plentiful as ever, nor can any change be anticipated. The present mode does not destroy them in any considerable numbers, each individual fish being the object of special pursuit. The solitary habits of the species will always protect them from wholesale capture, so destructive to schooling fish. Even if this were not the case, the evidence proves that spawning swordfish do not frequent our waters. When a female shad is killed, thousands of possible young die also. The swordfish taken by our fishermen carry no such precious burden.

“The small swordfish is very good meat,” remarked Josselyn, in writing of the fishes of England in the seventeenth century. Since Josselyn probably never saw a young swordfish, unless at some time he had visited the Mediterranean, it is fair to suppose that his information was derived from some Italian writer.

It is, however, a fact that the flesh of the swordfish, though somewhat oily, is a very acceptable article of food. Its texture is coarse; the thick, fleshy, muscular layers cause it to resemble that of the halibut in constituency. Its flavor is by many considered fine, and is not unlike that of the bluefish. Its color is gray. The meat of the young fish is highly prized on the Mediterranean, and is said to be perfectly white, compact, and of delicate flavor. Swordfish are usually cut up into steaks—thick slices across the body—and may be broiled or boiled.

The apparatus ordinarily employed for the capture of the swordfish is simple in the extreme. It is the harpoon with the detachable head. When the fish is struck, the head of the harpoon remains in the body of the fish, and carries with it a light rope which is either made fast or held by a man in a small boat, or is attached to some kind of a buoy, which is towed through the water by the struggling fish, and which marks its whereabouts after death.

The harpoon consists of a pole fifteen or sixteen feet in length, usually of hickory or some other hard wood, upon which the bark has been left, so that the harpooner may have a firmer hand-grip. This pole is from an inch and a half to two inches in diameter, and at one end is provided with an iron rod, or “shank,” about two feet long and five-eighths of an inch in diameter. This “shank” is fastened to the pole by means of a conical or elongated, cuplike expansion at one end, which fits over the sharpened end of the pole, to which it is secured by screws or spikes. A light line extends from one end of the pole to the point where it joins the “shank” and in this line is tied a loop by which is made fast another short line which secures the pole to the vessel or boat, so that when it is thrown at the fish it cannot be lost.

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.

The species of Tetrapturus which we have been accustomed to call T. albidus, abundant about Cuba, is not very usual on the coast of southern New England. Several are taken every year by the swordfish fishermen. I have not known of their capture along the southern Atlantic coast of the United States. All I have known about were taken between Sandy Hook and the eastern part of Georges Banks.

The Mediterranean spear-fish, Tetrapturus balone, appears to be a landlocked form, never passing west of the Straits of Gibraltar.The spear-fish in our waters is said by our fishermen to resemble the swordfish in its movements and manner of feeding. Professor Poey narrates that both the Cuban species swim at a depth of one hundred fathoms, and they journey in pairs, shaping their course toward the Gulf of Mexico, the females being full of eggs. Only adults are taken. It is not known whence they come, or where they breed, or how the young return. It is not even known whether the adult fish return by the same route. When the fish has swallowed the hook it rises to the surface, making prodigious leaps and plunges. At last it is dragged to the boat, secured with a boat-hook, and beaten to death before it is hauled on board. Such fishing is not without danger, for the spear-fish sometimes rushes upon the boat, drowning the fisherman, or wounding him with its terrible weapon. The fish becomes furious at the appearance of sharks, which are its natural enemies. They engage in violent combats, and when the spear-fish is attached to the fisherman’s line it often receives frightful wounds from the adversaries.

The spear-fish strikes vessels in the same manner as the swordfish. I am indebted to Capt. William Spicer, of Noank, Connecticut, for this note:

Mr. William Taylor, of Mystic, a man seventy-six years old, who was in the smack Evergreen, Capt. John Appleman, tells me that they started from Mystic, October 3, 1832, on a fishing voyage to Key West, in company with the smack Morning Star, Captain Rowland. On the 12th were off Cape Hatteras, the winds blowing heavily from the northeast, and the smack under double-reefed sails. At ten o’clock in the evening they struck a woho, which shocked the vessel all over. The smack was leaking badly, and they made a signal to the Morning Star to keep close to them. The next morning they found the leak, and both smacks kept off Charleston. On arrival they took out the ballast, hove her out, and found that the sword had gone through the planking, timber, and ceiling. The plank was two inches thick, the timber five inches, and the ceiling one-and-a-half-inch white oak. The sword projected two inches through the ceiling, on the inside of the “after run.” It struck by a butt on the outside, which caused the leak. They took out and replaced a piece of the plank, and proceeded on their voyage.
