Fifteen minutes' driving brought them to the second halt, a big basin of water, from which steam issued in a myriad of vents. Aconite suggested that they stroll down to the beach and take a look at the water. They found it in a slow turmoil, the mud rising from the bottom in little fountains of turbidity, the whole effect being that which might be expected if some mud-eating giant were watching his evening porridge, expecting it momentarily to boil. "I don't care much for this," said the Bride. "I'm not crazy about it myself," assented the Artist. "What's the next marvel?" asked the Colonel. "Wedded trees," said Aconite. "Getting sated with 'em," said the Poet. "Apollinaris Springs, Sylvan Lake, fine views of Yellowstone Lake and the mountains, bully rocks and things clear to Cody." "And on the other hand," said the Professor, "what are the features on the regular road from which we have diverged?" "Everything you come to see," responded Aconite. "Mud Volcano, with a clear spring in the grotto right by it; Mud Geyser, off watch for a year or more; Trout Creek, doubled around into the N.P. trade-mark; Sulphur Mountain--we can camp right near there, and see it in the morning, when we ought to see it--and on beyond, the Grand Cañon and everything. Besides--unless we go that-a-way, we'll never git back unless we come by the Burlington around by Toluca and Billings. Of course, it's all the same to me--I don't keer if we never go back or git anywhere. I'm havin' a good time." "Turn the plugs around," said the Colonel. In half an hour or so they were back on the great north road again. The horses seemed to feel the pull of the stable--still days ahead, for they trotted briskly along, while the tourists gazed with sated eyes on the beautiful Yellowstone River on the right hand, its pools splashing with the plunges of the great trout; and on their left the charming mountain scenery. Even the grotesque Mud Volcano, with its suggestions of the horrible and uncouth, failed to elicit the screams from the Bride, or the ejaculations of amazement from the men which characterized their deliverances earlier in the journey. Entering Hayden Valley, they were delighted at the sight in the middle distance of a dozen or more buffaloes, which held up their heads for a long look, and disappeared into the bushes. Not ten minutes later, fifty or sixty elk walked down to the Yellowstone to drink, crossing the road within a minute of the tourists' passage. Aconite pulled up in the shadow of Sulphur Mountain, the Hired Man, with the assistance of the party, soon had a fine fire blazing, and presently a pan of trout, hooked by the Bride, the Groom, the Artist and the Poet, and dressed by the skilful Aconite, were doing to a turn on the skillet.
