rumblings, its hollow echoing of our horses' trampling, its hissing craters, and its bubbling springs (lying sometimes within a few feet of the track), we entered the Upper Basin towards evening. Imagine the head of a valley walled in by pine-clad hills, and threaded by a stream that rushes through a bottom of desert white, dotted by clumps of pine-trees, from amidst which dense columns of steam rise on all sides and tower into the heavens. All evidences of the storm had cleared, and sinking amidst gold and purple clouds, the sun shed a fiery glow through the trees upon the ridges, that caused each twig—almost I had said each pine-needle—to stand out clearly against the sky. As we crossed the stream and mounted the opposite bank, a vast body of steam, followed by a jet of water 160 feet high, shot up into the air at the further end of the basin.

"There goes 'Old Faithful'!" exclaimed Dick; "the only reliable geyser in the Park. You can always bet on seeing him every sixty-five minutes."

Already encamped here, we found a large party of ladies and gentlemen from Boston, who were travelling through the Park. They informed us that the "Giantess" (perhaps the finest, but certainly the most capricious geyser of all) was expected to play in the morning, and the "Castle" to perform the next evening. There are nine principal geysers, namely, the Giant, Giantess, Castle, Grand, Beehive, Comet, Fan, Grotto, and Old Faithful. With the exception of the Grotto (which simply churns and makes an uproar), one or other of these tremendous fountains may be expected to cast a stream of water from one to two or even three hundred feet high into the air at any moment.

All geysers have not the same action, and most of them, in style of action, in the duration of their eruptions, and in the intervals that elapse between them, are apt individually to vary. Some play with laboured pumping, others throw a steady jet, some wear themselves out in a single effort, others subside only to commence again repeatedly. Thus an eruption may extend from two to twenty minutes—the approximate time occupied by the Grand—or even to one hour and twenty minutes, a period that the Giant has been known to play.

The colours that tinge the edges of some craters, and stain the courses of the streams which they send forth, are indescribably beautiful. The snowy whiteness of the grounding is relieved by dainty buffs, pale pinks, and softest écrus, deep yellows shot with brown, orange streaked with vermilion, or straying into crimson, chocolate merging into black, and interlined with lemon—by colours, in fact, run riot, and all glistening wet beneath the clearest crystal water, that in the centre of the crater deepens into a heavenly blue. From such brilliancy it is a relief to turn to the sullen pines upon the hills.

Extinct domes and craters overgrown by flourishing trees, or mounds still bare, and even steaming, with otherwise only their immense size to attest the mighty power that formed and has capriciously deserted them, are found here and there amongst those known still to be active. Some of the more modern craters are surrounded by the skeleton trunks of trees that their eruptions have killed, and which, under the action of their mineral waters, are rapidly becoming petrified; whilst in the conflict betwixt desolation and verdure, which, owing to the frequent variation of the centres of action, is constantly in progress, the lowly bunch-grass steals ground wherever it dared draw a blade.

Of the geysers whose eruptions we witnessed, the Grand was, I think, one of the most interesting. It played each evening at a regular hour. We were thus enabled to get comfortably into front seats, focus our glasses, and discuss the programme, as it were, before the performance commenced. This it did very abruptly, although the activity displayed at a small vent-hole, and the furious bubbling in another orifice connected with it, might be accepted as premonitory symptoms. Suddenly, with a single prefatory spurt, a vast column of water, over 200 feet high, was shot into the air. For a few minutes the pressure was maintained with unrelaxed vigour, then as suddenly it ceased, and the waters shrank back out of sight in the crater. Meanwhile the vent and cauldron were still furiously labouring, and subterraneous thunder shook the ground on which we stood. After a minute's cessation, the water burst forth again without warning, and with even greater violence. This continued until nine successive pulsations had occurred, the later efforts, however, perceptibly diminishing in grandeur.

It was a marvellous sight. The maddened rush of scalding water breaking free for a moment from its mysterious captivity, the gigantic columns of dense vapour, the showers of wreathed spray and crystal darts, forming, as they fell, screen upon screen of dazzling trellis-work, the lance-like jets pennoned with puffs of steam, the underground reports, the wondrous effects of the evening sun upon the silver spears that with lightning rapidity flashed forth and were shivered, broke and reformed again, the rainbow that shone through the slowly drifting masses of gauzy mist, the glitter and softness, passion and repose, formed a scene in which majestic fury was oddly mingled with the frailest loveliness. The packers and teamsters were right: "The Yellowstone Park and them geysers were jest indescribable." Over and over again was the admission forced from us, and not least heartily when, in the dim valley at night, the ghostly columns of vapour were seen winding from amidst impenetrable shadows and invading the silent heavens, whilst the rush and splashing of those mighty fountains from time to time broke the stillness of the breathless hours.

Slightly removed from the main group here is one of minor importance, containing, nevertheless, objects of considerable interest. Chief amongst these is the Golconda spring. In some respects this is one of the most striking features in the Upper Basin. It lies in the hollow of banks that form an exact representation of an inverted horse-hoof. By tiny terraces (the creation of deposits contained in its heavily charged waters) the stream issues from the frog of the hoof, and spreads over a large surface on its shallow course to the river. There is a strange fascination in striving to pierce the profound, pellucid, and brilliant depths of this extraordinary spring. Somewhat akin the feeling is to that which impels us to gaze and gaze into some deep ravine. One could stand for hours here, tracing the ivory cliffs bathed in what seems to be a pool of melted sapphires—down, down, down to where the gleaming waters grow black and awesome, and the creamy rocks contracting, lose their fantastic imagery, and mass in mystery to form the gloomy portals of a lower world.

As a game country the Yellowstone Park is a mistake. You may kill a few antelope, an occasional elk, or deer; it would not be impossible to happen on a stray bear or bison; but to go there merely for game is to court disappointment. Besides which, hunting is restricted in the Park. Beyond its boundaries, good game countries are easy of access; within them, summer tourists have scared away all the game.[3] Nevertheless, it is always possible to kill enough birds and antelope to vary the camp fare. It is a delightful climate there in summer, and a glorious country for gipsying. He must be hard to please who would tire soon of those cool, dim pine woods and grassy glades, where the chipmunk and squirrel curiously reconnoitre
