Most boys and girls think of a park as a little plot of ground with a fountain in its center and neat little flower beds arranged primly around. The Yellowstone Park is almost as large as Connecticut, and Uncle Sam has given it to America so that no one can ever spoil its beauty by building factories or cities there. Think of a park containing mountains two miles high, cataracts higher than Niagara, great canyons, and geysers which are the wonder of the world. There are hundreds of these geysers which are huge natural fountains spouting mud, boiling water, steam, and minerals. They burst out of the ground and then sink back leaving pools where wonderful colors seem to be painted on the rock. Each geyser has its own name and its own habits. Old Faithful used to spout every sixty minutes to the very second, but lately takes a little more time. He is getting old, but he still sends up a column of boiling water and steam 150 feet high, which is "going some." The Giant deserves its name for it spouts 200 feet, while the Black Growler fusses and mutters a lot but does very little real work. The Constant sends up a spout every minute with only a few seconds for rest in between. You would not think that with all this boiling water there could be any lakes of cold water, but the Yellowstone Lake is as clear and cold and its fish as fine as any you could find in the world. People claim that they have caught fish in the lake and then without moving a foot have cooked them in a pool of boiling water. We could believe this only we do not think the soldiers would let anyone fish there. Soldiers are stationed all around the park to keep tourists from carrying off souvenirs. Some tourists would run away with everything but the geysers if they had a chance. A geyser would be pretty hard to carry in ones suitcase. This great park has plains where bison run wild, great cliffs where the eagles rear their young, and forests where Mr. Grizzly makes himself quite at home. He even comes up to the hotels and carries off garbage and though he seems quite tame, we boys did not feel like getting too familiar with him. [Illustration: View from Mt. Jackson _Lake McDermott—from Many Glacier Camp_ Blue Lake Blackfeet Indians _Chief "Three Bears"_ GLACIER NATIONAL PARK] Glacier Park is way up at the northern edge of Montana. If it were a little farther north, it would be a Canadian citizen instead of being subject to Uncle Sam. It was the favorite hunting ground of the Blackfeet Indians but about 27 years ago copper was discovered there and Uncle Sam thought that the mines should be properly opened so he bought the land. There was not enough copper to make mining pay, but there was a stock of scenery so large that it would last forever, so Uncle Sam gave the land to his big family for another playground and the Blackfeet Indians now live on a reservation east of the park.
