Fort Wright, one of the military posts of the United States Government, is on the outskirts of the city on the bank of the Spokane River. Crossing the Cascade Range and passing down through the Green River Canyon, we reach Seattle or Tacoma, at the extreme south of Puget Sound. SHOSHONE CAVERN (NATIONAL MONUMENT) On the way to the Yellowstone National Park by way of the Wyoming entrance, at Cody, and three miles east of the great Shoshone Dam, a limestone cave has been set apart under the above title. The way in is rough and precipitous, and after entering the cave a descent by rope is necessary to reach the chambers, which are of unusual beauty and extend for more than a mile through galleries, some of which are heavily encrusted with crystals. THE YELLOWSTONE NATIONAL PARK The Yellowstone National Park is situated in the extreme northwest corner of Wyoming, extending a few miles into Montana on the north and into Idaho and Montana on the west. The reservation, set apart by act of Congress in 1872, is 5,500 square miles. From Salt Lake City or Ogden this park is reached by the Denver Rio Grande Railway or the Union Pacific in about 12 hours, but this trip, like so many others, can be arranged for you by whatever line you take. The Northern Pacific Railway offers a splendidly arranged tour to and through the park by way of Livingston, the Gate of the Mountains, and the Upper Yellowstone River to Gardiner, the original entrance to the park, and only five miles from Mammoth Hot Springs, the official headquarters of the park. The Yellowstone Park season is from June 15th to September 15th. It is not necessary to suggest what shall be seen here, for the trips are all arranged for one, and none should leave without making the complete tour. This park is unlike any other; it is unique in many ways. It contains geysers, mud volcanoes, mineral springs, and the most gloriously coloured pools. The Yellowstone Canyon can be compared with no other; here we have a riot of colour, said by many to rival the colours of the Grand Canyon, really so entirely different as to make comparison impossible. The walls of the Yellowstone Canyon are divided by a space of many miles at the top, which narrows down to three quarters of a mile at the base, where the foaming waters dash between them, and here the fragments of all the lost rainbows seem to have been collected.
