It should not be understood that the length of time required to traverse the distance between the Missouri and the Sacramento was wholly consumed in traveling. Nobody appeared to be in a feverish haste to finish the journey; and it was necessary to make occasional stops on the trail, where conditions were favorable, for the purpose of resting and refitting. A pleasant camping-place, with wood, water, and grass in plenty, was an invitation to halt and take a rest. This was called a "lay-by," and the halt sometimes lasted several days, during which wagon-tires were reset, ox-yokes repaired, clothes mended, and a general clean-up of the entire outfit completed preparatory to another long and uninterrupted drive toward the setting sun. If the stage of the journey immediately before us was an unusually difficult one, the stop was longer and the overhauling more thorough. A day's march averaged about twenty miles; an uncommonly good day with favorable conditions would give us twenty-five miles. The distances from camping-place to camping-place were usually well known to all wayfarers. By some subtle agency, information (and sometimes misinformation) was disseminated along the trail before us and behind us, and we generally knew what sort of camping-place we should find each night, and how far it was from the place of the morning start. So, when we halted for the night, we knew pretty accurately how many miles we had covered in that day's tramp. Of course riding was out of the question. We had one horse, but he was reserved for emergencies, and nobody but a shirk would think of crawling into the wagon, loaded down as it was with the necessaries of life, unless sickness made it impossible for him to walk. In this way we may be said to have walked all the way from the Missouri to the Sacramento. Much walking makes the human leg a mere affair of skin, bone, and sinew. We used to say that our legs were like chair-posts. But then the exercise was "good for the health." Nobody was ever ill. Grass, wood, and water were three necessities of life on the trail. But these were sometimes very difficult to find. Usually one or two of the party went on ahead of the rest and looked out a suitable camping-place where those essentials could be found. Fuel was sometimes absolutely unobtainable, possibly a few dry weeds and stalks being the only combustible thing to be found.
