WE are soon to lose the celebrated geysers of the Yellowstone Park, reports the New York Herald. These marvels of nature, which for many generations have excited the wonder of visitors and formed one of the extraordinary natural phenomena of the United States, are rapidly becoming extinct. The Roaring Mountain geyser, altho still emitting steam, has ceased to spout; the Black Growler is showing only the feeblest signs of life, and the renowned Fountain geyser, in the lower basin of the Yellowstone, and the Splendid and the Beehive, in the upper basin, are at the present time practically extinct. Thus five of the world's renowned geysers of the Yellowstone have gone out of business without any new hot springs appearing. The other geysers in the neighborhood, including the magnificent Old Faithful, the Devil's Inkpot, and the Minute geyser, all show that their power is rapidly diminishing and that their days are numbered. The celebrated European scientific paper entitled Ciel et Terre, in considering these facts, predicts that the geysers of the Yellowstone will exist for only a few more years, during which their activity will steadily diminish. Thus the Yellowstone Park, which has attracted visitors from all parts of the world, must needs be visited during the next few seasons if the most uncommon features of that wonderland, among the most celebrated geysers of the world, are to be seen at work.
