The whole story would fail if the fire did, as novelists never like to have their heroines left out in the cold. But it is as impossible for flames as it is for human beings to exist on air alone. It is scarcely less so for them to feed, as they are supposed to do, on such scanty grass. The truth is, that what the bison, with his close-cropping teeth, is enabled to grow fat on, makes but poor material for a first-class conflagration. The grass which covers the great plains of the Far West is more like brown moss than what its name implies. Perhaps as good an idea of it as is possible to any one who has never seen it, may be obtained by imagining a great buffalo robe covering the ground. The hair would be about the color and nearly the length of the grass, at the season in question. In the spring the plains are fresh and green, but the grass cures rapidly on the stalk, and before the end of July is brown and ripe. It will then burn readily, but the fire is like that eating along a carpet, and by no means terrifying to either man or brute. The only occasion when it could possibly prove dangerous is when it reaches, as it sometimes does, some of the narrow valleys where the tall grass of the bottom grows; but even then, a run of a hundred yards will take one to buffalo grass and safety. This latter fact we learned from actual experience, later on our trip. What a wild land we were in! A few puffs of a locomotive had transferred us from civilization to solitude itself. This was the "great American desert" which so caught our boyish eyes, in the days of our school geography and the long ago. A mysterious land with its wonderful record of savages and scouts, battles and hunts. We had a vague idea then that a sphynx and half a score of pyramids were located somewhere upon it, the sand covering its whole surface, when not engaged in some sort of simoon performance above. No trains of camels, with wonderful patience and marvelous internal reservoirs of water, dragged their weary way along, it was true; yet that animal's first cousin, the American mule, was there in numbers, as hardy and as useful as the other. Many an eastern mother, in the days of the gold fever, took down her boys discarded atlas, and finding the space on the continent marked "Great American Desert," followed with tearful eyes the course of the emigrant trains, and tried to fix the spot where the dear bones of her first-born lay bleaching. As a people, we are better acquainted with the wastes of Egypt than with some parts of our own land. The plains have been considered the abode of hunger, thirst, and violence, and most of our party expected to meet these geniuses on the threshold of their domain, and, while Shamus should fight the first two with his skillet and camp-kettles to war against the third with rifle and hunting-knife.
