Show CHAP. III. TEMPERATURE.-FIRST COME, FIRST SERVED. 159 feet wide. About three miles beyond it lay the " Foot of Ridge Station," near a willowy creek, called from its principal inhabitants the Muskrat.* The ridge from which it derives its name is a band of stone that will cross the road during to-morrow's ascent. Being a frontier place, it is a favorite camping-ground with Indians. To-day a war party of Sioux rode in, en route to provide themselves with a few Shoshonee scalps. We made a decided rise • to-day, and stood at least 6000 feet above the level, of the sea. The altitude of St. Louis being in roundnumbers 500 feet, and.reckoning the diminution of temperature at 1° F. = 100 yards, we are already 19° to 20° F. colder than before. The severity of the atmosphere and the rapid evaporation from the earth cause an increase of frigidity, to which the salts and nitrates :upbn the surface of the soil, by absorbing the hydrogen of the atmosphere - as is shown by the dampness of the ground and the absence of dust around the Saleratus Lakes- greatly add. Another remark made by every traveler in these regions is the marked influence upon the temperature caused by the presence and the absence of the sun. The day will be sultry and oppressive, arid a fire will be required, at night. In the morning, about 11 A.M;, the thermometer showed 80° Fahrenheit; at 4 P.M., the sky being clouded over, it fell 25°; before dawn, affected by the cold north wind from the snows about the Pass, it stood at 40°. The lowering firmament threatened rain, of which, however, the thirsty land was disappointed. Moreover, all were agreed that snow was to be expected in another fortnight, if not sooner. Glacial storms occasionally occur in July and August, so that in some years the land may be said to have no summer. In winter the sharpness of the cold is such that it can be kept out only by clothes of the closest texture; the mountain-men, like the Esquimaux, prefer to clothe themselves cap-a-pie in the prepared skins of animals. We were all animated with a nervous desire for travel, but there was the rub. The station-master declared that he had no driver, no authority to forward two wagonsful, and no cattle; consequently, that the last comers must be last served, and wait patiently at Rocky Ridge till they could be sent on. , They would find antelopes in plenty, perhaps a grizzly, and^plenty of plover, crows, and delicate little ground-squirrelsf by the burrow-ful, to " keep their hands in." We being the first comers, a title to preference rarely disputed in this law-and-rule-abiding land, prudently held ourselves aloof. The Judiciary, however, was * Fiber zibeiicus, a beaver-like animal that inhabits the banks of ponds and streams: it has a strong musky odor in summer only, and is greedily eaten by the Indians. t I had no opportunity of observing this clean, pTetty, and vivacious little animal, whose chirruping resembles that of a bird; but it appeared to be quite a different species from the common striped and spotted prairie-squirrel (Sperrnophilus tredecim-lineatus), or the chipmonk or chipmuk (S. striatus). |
