into its mouth and disappears down its throat; but not for long, for it again shoots up in four minutes, and is so regular in its action, that it has been christened "Young Faithful."

The plateau here spoken of—"The upper geyser basin"—is two or more miles long and of irregular width, probably averaging a third of a mile. It is all white with encrusted geyserite deposit often giving out a hollow sound to the tread. This deposit varies in thickness from a few inches to several feet. It is grayish white, resembling tarnished frozen snow.

THE SPLENDID—200 FEET HIGH.

But see that noble column spouting 200 feet high in a somewhat slanting stream not far from a quarter of a mile away. Close by a smaller jet shoots obliquely, mingling its spray with the larger one. The tourist is too far removed to see the brilliant rainbow formed in the mingling spray. But let him wait some hours and he may visit it again to witness another active eruption from the "Splendid Geyser," which pours four times a day from a simple hole in the rock, and has as yet builded himself no geyserite nozzle. A short walk brings one to the "Devil's Punch Bowl," where the old Fiend takes his nocturnal nip, from a basin a few feet in diameter, inclosed by an embossed rim a foot high and as regular as the raised edge of a Dresden punch bowl, and always boiling and seething to keep the tipple hot and ready.

In this plateau are hundreds of pools of exquisite colorings, and scores of geysers lifting more or less regularly and at shorter or longer intervals; some of the intervals being of hours, others of days and others still measured only by minutes. The geysers are all named in accordance with a supposed resemblance of their formation to some known thing, or to the character, size or quality of their eruptions; "The Queen," "The King," "The Bee-hive," "The Castle," "The Princess," "Old Faithful," "The Excelsior," "The Splendid" and so on. The pools take their names generally from the colorings of their rims or sides, or of the water held in them, as "The Emerald," "The Amethyst," "The Sunset," "The Rainbow" and "The Morning Glory." Some of the pools are named from the nature of their boilings, others from the rock formation in their throats and about their sides; "The Biscuit Bowl," "The Snow-ball," "The Spouter." Many of the names are by no means far fetched. The "Biscuit Bowl," for example, resembles a mass of well formed monster breakfast rolls, some in whitened dough, others in all stages of brown from the half done to the well baked.

The tourist approaches a flattened cone, with a base 600 or 800 feet in circumference, and fifty feet high, surmounted by the ruins of an old castle. The owner of the "Castle" has been growling all day and emitting an unusual amount of steam. He is evidently preparing to erupt, which he does at intervals of several days. His terrific growlings increase as the day wears on, and angry spurts of boiling water accompanied by steam show he is getting his temper up to white heat. He has been quiet for an unusual time of late and when aroused, like Othello, he will be fearfully moved. He makes a few angry premonitory belches and bellows. The noise is accompanied by a trembling of the earth for hundreds of yards. A mass of water is then ejected from 50 to 100 feet up, mixed with steam in dense mass. The flow of water is of short duration; but is of thousands of tons, and is followed by an emission of steam large enough to run an ocean steamer. This steam escape can be heard for a mile or more, and sounds like the roar made by a Long Island Sound steamer blowing salt from its boilers. The noise is continuous for an hour; it gradually lessens, however, until it ceases entirely. Steam is then lazily emitted continuously, and a loud gurgling noise is constant deep down in the Geyser throat. This is more or less the case with nearly all of the geysers. A few, however, become so quiet, that very close attention is necessary to catch any boiling noise. The "Castle" geyser blows off for hours before his steam generators are cleaned.

IT SCARES THE WHITE MAN.

Our red cheeked tourist has stoicism, but he cannot stay over this Devil's kitchen long enough to see half of the mighty vents in action. One, which but rarely plays, shakes the very earth. A good white man, who flatters himself that he is a child of God and believes in sovereign reigning grace, is struck by it with awe akin to terror.

But there is one geyser which becomes familiar to the civilized tourist and seems to win from him a sort of affection, because of his conscientious behavior. His very regularity, however, would strike the more terror into the heart of the untutored red man. He has built his home under a mound 300 yards in circumference and twenty or so feet high at its apex, upon which he has cast a geyserite chimney ten to fifteen feet high and six or eight in diameter. This chimney he has ornamented within and without with huge tufted beads, and painted those within with rose and white, orange and brown, red and grey. These adjuncts, however, do not compare to those of many others, for some of them seem to have wrapped their throats in great pillows, hard as gypsum, but looking as soft and tufty as if made of swans down, while others have painted their inside linings with all the tints of the rainbow; and their crystal clear water seems to have caught the cerulean blue from the heavens and are holding it in solution.

But to return to this geyser; for nearly an hour he has been as quiet as a lamb, just enough of steam arising from his throat to show he is gently breathing. The steam breath gradually grows and is exhaled with more vigor. Presently he belches up a barrel or so of water which falls back into his throat. Then in a minute come two or three such little spasms, when up lifts a rounded column two or three feet in diameter, rising higher and higher in exact perpendicularity 150 feet high. The jet breaks more or less as it rises into pointed sprays, which, when there is no wind blowing, fall with almost precise regularity about the up going column.

WATCHES ARE SET BY IT.

In about five minutes the jet of water ceases, but is followed by considerable steam emissions for a quarter of an hour, when one can look down into his throat and see the crystal water ten to fifteen feet below the apex, and all quiet and still. So regular is the action of this geyser that one could, by watching it, almost dispense with a watch. He never plays in less than sixty-three minutes, and never delays action longer than seventy. Indeed, some of his most constant admirers declare these variations are the fault of watches, not of "Old Faithful." Thus he is named, and as such is known far and near. There are several of these geyser-basins scattered over the park from ten to twenty-five miles apart, the principal ones being the "Norris," the "Lower Geyser Basin" and the "Upper Geyser Basin." These are reached in succession on the tourist road from "Mammoth Hot Springs."

The regular tourist, starting from Mammoth Hotel, dines at the "Norris" and sleeps at the "Lower Basin." The next day, if he prefers to go on with his coach, he passes the "Excelsior," which is the hugest of all the geysers, and has been for two or three years nearly quiet, but this year is in tolerable eruption. It is a vast pool, possibly over two hundred feet in diameter. When quiet, water about twenty feet below the pool rim boils, seethes and tosses in horrible motion. It erupted just as our party reached it, but not in one of its grand actions. A mass of water possibly many feet in diameter was lifted fifty or more feet in the air. It is said that when in full eruption the height of the column is from two to three hundred feet. This I doubt. The mass of steam enveloping the jet is so great that the water column is entirely hidden, and has given rise to exaggeration on the part of those who have seen it at its best. The basin of the Excelsior is called "Hell's half acre," and it is by no means a misnomer,
