Chapter 11
A school of feeding bonefish came toward us. I counted eleven tails out of the water. They were around my bait. Now or never, I thought, waiting frantically! But they went on feeding--passed over my line--and came so near the boat that I could plainly see the gray shadow shapes, the long, sharp noses, the dark, staring eyes. I reeled in to find my bait gone, as usual. It was exasperating.
We had to give up then, as darkness was not far off. Sam was worried about the boat. He rowed while I stood up. Going back, I saw bonefish in twos and fours and droves. We passed school after school. They had just come in from the sea, for they were headed up the flat. I saw many ten-pound fish, but I did not know enough about bonefish then to appreciate what I saw. However, I did appreciate their keen sight and wariness and wonderful speed and incredible power. Some of the big surges made me speculate what a heavy bonefish might do to light tackle. Sam and I were disappointed at our luck, somewhat uncertain whether it was caused by destructive work of crabs or the wrong kind of bait or both. It scarcely occurred to us to inquire into our ignorance.
We found the boat hard and fast in the mud. Sam rowed me ashore. I walked back to camp, and he stayed all night, and all the next day, waiting for the tide to float the boat.
After that on several days we went up to the flat to fish for bonefish. But we could not hit the right tide or the fish were not there. At any rate, we did not see any or get any bites.
Then I began to fish for bonefish in front of my cottage. Whenever I would stick my rod in the sand and go in out of the hot sun a bonefish would take my bait and start off to sea. Before I could get back he would break something.
This happened several times before I became so aroused that I determined to catch one of these fish or die. I fished and fished. I went to sleep in a camp-chair and absolutely ruined my reputation as an ardent fisherman. One afternoon, just after I had made a cast, I felt the same old strange vibration of my line. I was not proof against it and I jerked. Lo! I hooked a fish that made a savage rush, pulled my bass-rod out of shape, and took all my line before I could stop him. Then he swept from side to side. I reeled him in, only to have him run out again and again and yet again. I knew I had a heavy fish. I expected him to break my line. I handled him gingerly. Imagine my amaze to beach a little fish that weighed scarcely more than two pounds! But it was a bonefish--a glistening mother-of-pearl bonefish. Somehow the obsession of these bonefishermen began to be less puzzling to me. Sam saw me catch this bonefish, and he was as amazed as I was at the gameness and speed and strength of so small a fish.
Next day a bonefisherman of years' experience answered a few questions I put to him. No, he never fished for anything except bonefish. They were the hardest fish in the sea to make bite, the hardest to land after they were hooked. Yes, that very, very slight vibration of the line--that strange feeling rather than movement--was the instant of their quick bite. An instant before or an instant after would be fatal.
It dawned upon me then that on my first day I must have had dozens of bonefish bites, but I did not know it! I was humiliated--I was taken down from my lofty perch--I was furious. I thanked the gentleman for his enlightenment and went away in search of Sam. I told Sam, and he laughed--laughed at me and at himself. After all, it was a joke. And I had to laugh too. It is good for a fisherman to have the conceit taken out of him--if anything can accomplish that. Then Sam and I got our heads together. What we planned and what we did must make another story.

SWORDFISH
_From records of the New York Bureau of Fisheries, by G. B. Goode_
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:
"It strikes with the accumulated force of fifteen double-handed hammers. Its velocity is equal to that of a swivel shot, and is as dangerous in its effect as a heavy artillery projectile."
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:
Nature her bounty to his mouth confined, Gave him a sword, but left unarmed his mind.
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.
Last Wednesday the court of common pleas--rather a strange place, by the by, for inquiring into the natural history of fishes--was engaged for several hours in trying to determine under what circumstances a swordfish might be able to escape scot-free after thrusting his snout into the side of a ship. The gallant ship _Dreadnought_, thoroughly repaired and classed A1 at Lloyd's, had been insured for £3,000 against all risks of the sea. She sailed on March 10, 1864, from Columbo for London. Three days later the crew, while fishing, hooked a swordfish. Xiphias, however, broke the line, and a few moments after leaped half out of the water, with the object, it should seem, of taking a look at his persecutor, the _Dreadnaught_. Probably he satisfied himself that the enemy was some abnormally large cetacean, which it was his natural duty to attack forthwith. Be this as it may, the attack was made, and the next morning the captain was awakened with the unwelcome intelligence that the ship had sprung a leak. She was taken back to Columbo, and thence to Cochin, where she hove down. Near the keel was found a round hole, an inch in diameter, running completely through the copper sheathing and planking.
As attacks by swordfish are included among sea risks, the insurance company was willing to pay the damages claimed by the owners of the ship, if only it could be proved that the hole had been really made by aswordfish. No instances had ever been recorded in which a swordfish which had passed its beak through three inches of stout planking could withdraw without the loss of its sword. Mr. Buckland said that fish have no power of "backing," and expressed his belief that he could hold a swordfish by the beak; but then he admitted that the fish had considerable lateral power, and might so "wriggle its sword out of the hold." And so the insurance company will have to pay nearly £600 because an ill-tempered fish objected to be hooked and took its revenge by running full tilt against copper sheathing and oak planking.
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.
