They all resemble in character the two I have described, the only difference being that they are infinitely smaller, and of much less power and importance. 'As our principal object in coming so far was to see an eruption of the Great Geyser, it was of course necessary to wait his pleasure; in fact, our movements entirely depended upon his. For the next two or three days, therefore, like pilgrims round some ancient shrine, we patiently kept watch, but he scarcely deigned to vouchsafe us the slightest manifestation of his latent energies. Two or three times the cannonading we heard immediately after our arrival recommenced--and once an eruption to the height of about ten feet occurred; but so brief was its duration, that by the time we were on the spot, although the tent was not eighty yards distant, all was over; as after every effort of the fountain, the water in the basin mysteriously ebbed back into the funnel. This performance, though unsatisfactory in itself, gave us an opportunity of approaching the mouth of the pipe, and looking down its scalded gullet. In an hour afterward the basin was brimful as ever. 'On the morning of the fourth day a cry from the guides made us start to our feet, and with one common impulse rush toward the basin. The usual subterranean thunders had already commenced. A violent agitation was disturbing the centre of the pool. Suddenly a dome of water lifted itself up to the height of eight or ten feet--then burst and fell; immediately after which a shining liquid column, or rather sheaf of columns, wreathed in robes of vapor, sprang into the air, and in a succession of jerking leaps, each higher than the last, flung their silver crests against the sky. For a few minutes the fountain held its own, then all at once appeared to lose its ascending energy. The unstable waters faltered--drooped--fell, 'like a broken purpose,' back upon themselves, and were immediately sucked down into the recesses of their pipe. 'The spectacle was certainly magnificent; but no description can give an idea of its most striking features. The enormous wealth of water, its vitality, its hidden power, the illimitable breadth of sunlit vapor, rolling out in exhaustless profusion--all combined to make one feel the stupendous energy of nature's slightest movement.
