Among the wonders of Yellowstone Park the geysers are the most noted. One of them is called Old Faithful, because he always spouts on time. He gives a grand exhibition every hour, whether he has an audience or not. He spouts, and sputters, and hisses and throws a huge column of hot water into the air, and then quiets down and gets ready for another performance. Another geyser in Yellowstone Park is called the Beehive, being cone-shaped like the old-fashioned beehive. It throws up a column of water more than two hundred feet. Castle Geyser is another that throws up a larger column of hot water than either of the above. The falling water has built up a huge crater that resembles a castle, hence its name. But the largest geyser in Yellowstone Park is called the Giantess. The well or orifice through which it sends up its column of water is more than twenty feet in diameter. The steam arises after the water has been ejected. A body of water more than twenty feet in diameter ascends in one gigantic column to the height of ninety feet. Then from the apex of this column five jets shoot up, radiating slightly from each other to the height of two hundred and fifty feet from the ground. The earth trembles under the descending deluge of this vast column of water, a thousand hissing sounds are heard in the air, rainbows encircle the summits of the jets with a halo of celestial glory. The falling water plows up and bears away the shelly strata, and a seething flood pours down the slope into the river. It is the grandest and most terrible fountain in the world. Visitors have to wait hours and sometimes days before the geyser will entertain them with an exhibition of its power and beauty. Commander Ford, of the British Navy, says that one of the geysers of Iceland, called the Stroker, can be excited to action by throwing stones and turf down into the pit, and that the geyser resents the insult by throwing them up. He found that it usually took about forty minutes after throwing in the stones before they were thrown up. It occurred to him that he might send his dinner down and have it sent back to him well cooked. So he wrapped a leg of mutton and a fowl in a cloth and threw them into the boiling caldron, where he would never see them again unless they were thrown up. After waiting the usual forty minutes he began to regret his venture, but the geyser was only seven minutes behind time, and up came his leg of mutton and fowl done to a turn. Aside from the beauty of the columns of water, vapor and steam geysers send up, the waters are all the time depositing carbonate of lime and silica, and building up craters of many interesting forms.
