202 THE THRESHER. 



on backing as soon as it feels the obstruction, is cauylit by the tightening of tlie noose. Tlie 

 natives then go oif in their canoes, chasing the bewildered Shark, who is unable to dive 

 on account of the floating log, and who is so lustily battered about the head with the heavy 

 clubs so admirably made by those ingenious natives, that it is soon killed and hauled ashore 

 in ti-iumi)h. 



The color of tlie White Shark is ashen-brown above, and white below. 



The Great White Shark is named in America Man-eater, and Atwood' s Shark, though the 

 latter tei'm, applied in honor of the sea captain of Province town, Mass., who assisted greatly 

 in contributing to Dr. Storer's report on the Fishes of Massachusetts, is now dropped, as the 

 species is regarded as identical with the European. It is found in all temperate and tropical 

 seas, and is one of the largest of Sharks, reaching a length of fifteen feet, and the weight 

 of nearly a ton. 



This Shark is especially abundant on the Florida Reef. AVhile resident there, at Fort 

 Jefferson, our lads of the garrison had much sport in capturing them. On one occasion, 

 one measui'ing ten feet in length, and very l)ulky, as this species is, was hooked off shore. 

 The boys had one of the fiat pontocm l)oats of the engineers, otherwise they would have been 

 taken oft' seaward. As it was, they had enough to do. Several soldiers went to their 

 assistance, and rowed the paity in, while the prize, hauled "shoi't up" to the gunwale, made 

 savage resistance. On gaining the moat of the fort jilanks were laid, and the monster hauled 

 over into the confined water of the ditch. Here he remained, restlessly swimming its length 

 of watei's, steadily refusing any food. In about two months he died, seemingly exhausted. 



The Basking Sharks, or Whale-nosed, are represented in American waters by the Great 

 Basking Shark {CetorMnus maxiTmis.) It is thought to be the largest existing Shark, being 

 nearly forty feet in length. It is quite notable, among other things in being a resident in 

 Arctic waters, from whence it strays as far as the latitude of Portugal, and of Virginia. It is 

 also strange in being so enormous in bulk, and at the same time quite harmless, as it has but 

 a small month and quite insignificant armament of teeth. It is called in Europe Sun-fish, 

 Sail-fish, and Hoe-mother, from the habit of basking in the sun on the surface of the sea ; 

 from the sail-like appearance of its high dorsal fin when near the surface, and from the fact 

 that the fishennen affect to believe it to be the Mother of the Hoe, or Piked Dog-fish, 

 respectively. 



It seems to be of a rather dull and listless character, allowing itself to l)e approached quite 

 closely by a boat, without giving any signs of ahirm until the bow of the boat actually touches 

 its person. 



The gill apertures of the Basking Shark ai'e extremely long, reaching almost across the 

 neck. The head is conical, the muzzle short, and the eyes near the snout. Tlie skin is very 

 rough to the touch, whether the hand be passed from head to tail or vice versa, and the color 

 is blackish-bi'own, glossed with a bluish tint. 



Among our fisheruien it is known as Bone Shark and Elephant Shark. A specimen 

 drifted asliote at Provincetown, Mass., which afforded six barrels of oil. taken from the liver 

 alone, which sold for §10.'?. The food of this Shark is probably small mollusks and crustaceans, 

 and, according to some authors, marine alg?e. 



A WELL-KNOWN species, familiar under the names of Thresher {Alryjrias mdj^es), Fox 

 Shark, Sea Fox, Sea Ape, Swingle-tail, Long-tail, etc., is at once to be recognized by the 

 peculiar form of the head and the wonderfully long upper lobe of the tail, which equals 

 in length the body from the tij) of the snout to the base of the tail. The lower lobe is quite 

 short, and in no way conspicuous. 



This fish is appropriately called the Thivsher on account of its habit of using its long and 

 flexible tail after the fashion of a quarter-staff, and dealing the most tremendous blows on or 

 nenr any object that may excite its ire. Sometiuies it seems to employ its tail in playing off a 

 practical joke or frightening away dolphins or other creatures that are disporting them- 

 selves in apparent security. The following short account by Captain Crow will give a
