vessels, and in the banner year of the industry, 1846, 735 ships engaged in it, the major part of the fleet hailing from Nantucket.  The cruises at first were toward Greenland after the so-called right whales, a variety of the cetaceans which has an added commercial value because of the baleen, or whalebone, which hangs in great strips from the roof of its mouth to its lower jaw, forming a sort of screen or sieve by which it sifts its food out of prodigious mouthfuls of sea water.  This most enormous of known living creatures feeds upon very small shell-fish, swarm in the waters it frequents.  Opening wide its colossal mouth, a cavity often more than fifteen feet in length, and so deep from upper to lower jaw that the flexible sheets of whalebone, sometimes ten feet long, hang straight without touching its floor, it takes a great gulp of water.  Then the cavernous jaws slowly close, expelling the water through the whalebone sieve, somewhat as a Chinese laundryman sprinkles clothes, and the small marine animals which go to feed that prodigious bulk are caught in the strainer.  The right whale is from 45 to 60 feet long in its maturity, and will yield about 15 tons of oil and 1500 weight of whalebone, though individuals have been known to give double this amount.

Most of the vessels which put out of Nantucket and New Bedford, in the earliest days of the industry, after whales of this sort, were not fitted with kettles and furnaces for trying out the oil at the time of the catch, as was always the custom in the sperm-whale fishery.  Their prey was near at hand, their voyages comparatively short.  So the fat, dripping, reeking blubber was crammed into casks, or some cases merely thrown into the ship’s hold, just as it was cut from the carcass, and so brought back weeks later to the home port—­a shipload of malodorous putrefaction.  Old sailors who have cruised with cargoes of cattle, of green hides, and of guano, say that nothing that ever offended the olfactories of man equals the stench of a right-whaler on her homeward voyage.  Scarcely even could the slave-ships compare with it.  Brought ashore, this noisome mass was boiled in huge kettles, and the resulting oil sent to lighten the night in all civilized lands.  England was a good customer of the colonies, and Boston shipowners did a thriving trade with oil from New Bedford or Nantucket to London.  The sloops and ketches engaged in this commerce brought back, as an old letter of directions from shipowner to skipper shows, “course wicker flasketts, Allom, Copress, drum rims, head snares, shod shovells, window-glass.”  The trade was conducted with the same piety that we find manifested in the direction of slave-ships and privateers.  In order that the oil may fetch a good price, and the voyage be speedy, the captain is commended to God, and “That hee may please to take the Conduct of you, we pray you look carefully that hee bee worshipped dayly in yor shippe, his Sabbaths Sanctifiede, and
