One of the richest and best of the smaller class of American cities is New Bedford; and the secret of its wealth and beauty is _oil_. It is but a few years since the immense fleet of vessels that made that thrifty port their home went out with certainty of success in their dangerous enterprises, and came back loaded down with spoil. All that beautiful wealth was won from the deep, and for years as many ships came and went as there were dwellings to give them speed and welcome. But the glory and the gain of the whale-fishery are past. The noble prey, too persistently and mercilessly pursued, has retired northward, and hidden among the icebergs. Now, when a ship's crew win a cargo, they win it from the clutches of eternal frost. It seems certain that the fishery will dwindle, year after year, until, at last, only a few adventurers will linger near the pole, to watch for the rare game that once furnished light for the civilized world. All this is very unpleasant for New Bedford; but are we to have no more oil? Is nature failing? Will the time come when people must sit in darkness? A few months ago a man in Pennsylvania took it into his head to probe the ground for the source of a certain oil that made its appearance upon the surface. Down, down into the bowels of the earth he thrust his steam-driven harpoon, until he touched the living fountain of oil, which, gushing up, half drowned him. Now, all the region round about him swarms with industry. Thousands of men are hurrying to and fro; the puff of the engine is heard everywhere; tens of thousands of barrels of oil are rolled out and turned into the channels of commerce; eager-eyed speculators throng all the converging avenues of travel, and a waiting world of consumers take the oil as fast as it is produced. Men in Virginia, New York, and Ohio are awaking to the consciousness that, while they have been paying for oil from the far Pacific, they have been living within three hundred feet of deposits greater than all the cargoes that ever floated in New Bedford harbor. For hundreds, and, probably, for thousands of years, men have walked over these deposits with no suspicion of their existence. Geologists have looked wise, as is their habit, but have given no hint of them. The simple truth appears to be that when, in the history of the world, it became necessary for these firmly-fastened store-houses of oil to be uncovered, they were uncovered. Nature had held them for untold thousands of years for just this emergency. When the whales ceased spouting, the earth took up the business; and "here she blows" and "there she blows" are heard in Tideoute and Titusville, while New Bedford sits sadly by the sea, and thinks of long absent crews to whom the cry has become strange.
