Here we entered a stretch of territory not as yet brought before the reader's notice.
Passing on, a ride of between fifty and sixty miles brought us to a large grove of willows at the mouth of a sand-creek, where we remained the day following.
The vicinity contained the relics of three or four Indian forts, constructed of logs, —one or two of which were in an almost entire state of preservation, and afforded a correct illustration of Indian military genius. Their forms were oval, and the roofage so complete, we were amply sheltered in one of them from a heavy shower which fell during our stay.
From this point (properly denominated Fort Grove) to the forks, the country is rather sterile and rolling, with the exception of the river bottoms, which, as usual, are possessed of a rich soil and vary in width from one to five miles. There is scarcely a tree, worth naming, upon either bank of the river for the whole extent.
The expanse lying to the northward is quite broken and hilly, with some few pines and cedars at the heads of ravines.
Previous to leaving Fort Grove I experienced an attack of the fever and ague, which recurred, at intervals of once in two days, until we reached Fort Lancaster.
Resuming our journey, a ride of some ten miles brought us to the mouth of Pole creek, a large affluent of the right shore. This is a clear and handsome stream, running through a rich valley of considerable width. Its entire course affords but very little timber, and the prairie upon either side is generally sandy and barren.
Journeying on about seventy-five miles further, we came to a large stream called la Fouchett aux Castors, or Beaver Fork.
This creek heads in the highlands between the Platte and Arkansas, and traces its course through a sandy country, varied by diminutive hills of clayey soil, for a distance of nearly two hundred miles. — It presents many beautiful bottoms of a rich vegetable mould, with here and there small clusters of timber.
Some forty or fifty miles above Beaver creek, we crossed Bijou, another large affluent of the left shore. The water at the mouth of this stream was shallow, dispersing itself in several small channels, over a bed of gravel and quicksand, about four hundred yards wide, and enclosed by abrupt banks of clay and sand.
For several miles above its junction with the Platte no timber appears; but further on, many large groves relieve the eye, and invite the traveller to their shade, while broad meadows and rich bottoms, clothed with grass an flowers, cheer the beholder and delight his fancy.
Aug. 30th. A ride of ten or fifteen miles, from this point, brought us to a camp of whites, in the employ of Bent and St. Vrain, occupying a small island in the Platte. They were guarding a quantity of robes with which they had attempted to descend the river, but were unable to proceed further on account of low water.
I was much gratified at here meeting an old acquaintance, with whom I had passed a portion of the previous winter upon White river.
