At Craig Pass, the cayuses were stopped so that all might feast their eyes on the little Isa Lake, frowned on by stern precipices, but smiling up into the blue, its surface flecked with water-lilies. "An' hyar," said Aconite, "we hev a body of water that at one end empties into the Atlantic Ocean's tributaries, an' at the other waters the Pacific slope." "Which is which?" asked the Colonel. "The east end runs into the Pacific, and the west into the Atlantic," replied Aconite, quite truthfully. "What's that!" exclaimed the Hired Man. "Do yeh mean to say we've got over on the coast by drivin' east--toward Ioway?" "You've said 'er," said Aconite. "I tell you," said the Hired Man, as the others began studying their maps to clear up this geographic anomaly, "I tell you that there ain't no way of understandin' the 'tother-end-toness of this place, except by sayin' that the hull thing is a gigantic streak of nature." "The most rational explanation," said the Groom, "that I've heard. Mr. Hired Man sets us all right. Drive on, Aconite!" Down Corkscrew Hill they volplaned, thrilled and somewhat scared by the speed of the cayuses, which flew downward in joyful relief at the cessation of the uphill pull to the pass. At the bottom there was a halt to afford a glimpse of Shoshone Lake, and far off to the south the exquisite Tetons, their summits capped with pearl. The visit to Shoshone Lake with its gorgeous geysers was to be postponed until after they should arrive at the thumb of Yellowstone Lake, and make camp. An hour of steady driving succeeded. They drowsed in their seats, torpid from the early start and the days of strenuous sight-seeing. The road ran through a quiet forest, and there was something not unpleasant in the fact that the curtain of trees shut off the view--until suddenly at a turn in the highway, there burst upon their sight that most marvelous of inland seas, Yellowstone Lake. Straight away extended its waters, for twenty miles, to the dim shores of Elk Point, where the pines carried the wonderful landscape upward, their gloom cutting straight across the view, between the mirror-like sheen of the lake, to timber-line on the azure Absarokas, standing serenely across the eastern sky, their serrated summits picked out with snow against the blue. A huge chalice lay the lake, reared to a height of a mile and a half above the dusty and furrowed earth where folk plow and dig and make their livings, the crown jewel of the continent's diadem, unutterably, indescribably lovely, filled with crystalline dew. The tourists caught their breaths. Aconite said nothing. For a long time they stood, until the horses began to move backward and forward, uneasy at the unwonted stay. The Bride was holding the Groom's hand, her eyes glistening with tears.
