Nore.—The pugnacity of the sword-fish and its wonderful strength 
have been shown on many occasions. The yacht Red-Hot, of New Bed-

same year, and the cargo had to be discharged in consequence. The 
ship Fortune was pierced in 1827, the sword penetrating copper, an 
inch board under-sheathing, a three-inch plank of hard wood, twelve 
inches of solid white-oak timber, and, lastly, the head of an oil-cask.
