"Sperm whale try out de bes' oil," the garrulous old whaleman went on. "Bowhead and right whale got thicker blubber and make more oil, but sperm whale oil de bes'. He got big cistern--what dey call a 'case'--in de top ob his head and it's full o' spermaceti, sloshing about in dere and jes' as clear as water. His old head is always cut off and hoist on deck to bale out dat case. Many times dey find ambergrease (ambergis) floating beside a dead sperm whale. It's solid and yellowish and stuck full o' cuttle feesh beaks dat de whale's done swallowed but ain't digest. Dey makes perfume out o' dat ambergrease and it's worth its weight in gold. I've offen seen it in chunks dat weighed a hundred pounds. "You see a sperm whale ain't eat nothin' but cuttle feesh--giant squid, dey calls 'em, or devil feesh. Dey certainly is terrible fellers--is dem devil feesh. Got arms twenty or thirty feet long wit' sucking discs all over 'em and a big fat body in de middle ob dese snaky arms, wit' big pop-eyes as big as water buckets and a big black beak like a parrot's to tear its food wit'. Dose devil feesh. Dey certainly is terrible fellers--is dem sperm whale nose 'em out and eat 'em. Some time dey comes to de top and de whale and de cuttle feesh fights it out. I've hearn old whalers say dey seen fights between sperm whale and cuttle feesh but I ain't never seen dat and I reckon mighty few fellers ever did. But when a sperm whale is killed, he spews out chunks o' cuttle feesh and I've seen de water about a dead sperm thick wit' white chunks of cuttle feesh as big as a sea ches' and wit' de suckin' disc still on 'em. "Blow!" said Gabriel again with his eyes on the whale. "Dat feesh certainly some traveler." We were hauling closer to the whale. I could see it distinctly by this time and could note how square and black its head was. Its appearance might be compared not inaptly to a box-car glistening in the sun under a fresh coat of black paint. It did not cut the water but pushed it in white foam in front of it. "Sperm pretty scarce nowadays," Gabriel resumed. "Nothing like as plentiful in Pacific waters as dey used to be in de ole days. Whalers done pretty well thinned 'em out. But long ago, it used to be nothin' to see schools of a hundred, mostly cows wit' three or four big bulls among 'em." "Any difference between a bowhead and a right whale?" some one asked. "O good Lord, yes," answered Gabriel. "Big difference. Right whale thinner whale dan a bowhead, ain't got sech thick blubber neither. He's quicker in de water and got nothin' like such long baleen. You ketch right whale in Behring Sea. I ain't never see none in de Arctic Ocean. You ketch bowhead both places. Right whale fightin' feesh, too, but he ain't so dangerous as a sperm."
