Rh lows, and cedars, which are disappearing before the emigrant's axe. The cedar now becomes an important tree. It will not grow on the plains, owing to the dryness of the climate and the excessive cold; even in the sheltered ravines the wintry winds have power to blight all the tops that rise above prairie level, and where the locality is better adapted for plantations, firs prevail. An interesting effect of climate upon the cedar is quoted by travelers on the Missouri River. At the first Cedar Island (43° N lat.) large and straight trees appear in the bottom lands, those on the bluffs being of inferior growth; higher up the stream they diminish, seldom being seen in any number together above the mouth of the Little Cheyenne (45° N. lat.), and there they are exceedingly crooked and twisted. In the lignite formations above the Missouri and the Yellow Stone, the cedar, unable to support itself above ground, spreads over the hill-sides and presents the appearance of grass or moss.

Beyond the immediate banks of the Platte the soil is either sandy, quickly absorbing water, or it is a hard, cold, unwholesome clay, which long retains muddy pools, black with decayed vegetation, and which often, in the lowest levels, becomes a mere marsh. The wells deriving infiltration from the higher lands beyond are rarely more than three feet deep; the produce is somewhat saline, and here and there salt may be seen efflorescing from the soil around them. In the large beds of prêle (an equisetum), scouring rush, and other aquatic plants which garnish the banks, myriads of musquetoes find a home. Flowers of rich, warm color appear, we remark, in the sandy parts: the common wild helianthus and a miniature sunflower like chamomile, a thistle (Carduus leucographus), the cactus, a peculiar milk-plant (Asclepias syrivea), a spurgewort (Asclepias tuberosa), the amorpha, the tradescantia, the putoria, and the artemisia, or prairie sage. The richer soils and ravines produce in abundance the purple aster—violet of these regions—a green plant, locally known as "Lamb's Quarters," a purple flower with bulbous root, wild flax with pretty blue blossoms, besides mallow, digitalis, anemone, streptanthis, and a honeysuckle. In parts the valley of the Platte is a perfect parterre of wild flowers.

After satisfying hunger with vile bread and viler coffee—how far from the little forty-berry cup of Egypt!—for which we paid 75 cents, we left Kearney Station without delay. Hugging the right bank of our strange river, at 8 A.M. we found ourselves at Fort Kearney, so called, as is the custom, after the gallant officer, now deceased, of that name.

Every square box or block-house in these regions is a fort; no misnomer, however, can be more complete than the word applied to the military cantonments on the frontier. In former times the traders to whom these places mostly belonged erected quadrangles of sun-dried brick with towers at the angles; their forts still
