We ascended this day twelve miles, which is the utmost stretch of our exertions against the turbid and heavy tide of this stream. Our captain (Ensminger) looked in the evening as if he had been struggling all day in a battle, and his men took to their pallets as if exhausted to the last degree.

July 22d. I have seen very little, thus far, in the Mississippi, in the shape of fish. The only species noticed has been the gar; one of which I caught, as described, from the side of the boat, while lying at the mouth of the Ohio. Of all rivers in the West, I should think it the least favorable to this form of organized matter. Of the coarse species of the catfish and buffalo-fish which are found in its waters, I suppose the freshet has deprived us of a sight.

Of antiquities, I have seen nothing since leaving the Ohio valley till this day, when I picked up, in my rambles on shore, an ancient Indian dart, of chert. The Indian antiquities on the Illinois shore, however, are stated to be very extensive. Near the Kaskaskia river are numerous mounds and earthworks, which denote a heavy ancient population.

The limestone cliffs, at the place called Dormant Rocks, assume a very imposing appearance. These precipitous walls bear the marks of attrition in water-lines, very plainly impressed, at great heights above the present water-level; creating the idea that they may have served as barriers to some ancient ocean resting on the grand prairies of Illinois.

We were passed, near evening, by the little steamer Harriet, on her descent from St. Louis. This vessel is the same that was noticed on the 11th, on her ascent, and is the only representative of steam-power that we have observed.[5] Our ascent this day was estimated at thirteen miles.

July 23d. Passing the Platten creek, the prominence called Cornice Rock, and the promontory of Joachim creek, an ascent of five miles brought us to the town of Herculaneum. This name of a Roman city buried for ages, gives, at least, a moral savor of antiquity to a country whose institutions are all new and nascent. It was bestowed, I believe, by Mr. Austin, who is one of the principal proprietors of the place. It consists of between thirty and forty houses, including three stores, a post-office, court-house, and school. There are three shot-towers on the adjoining cliffs, and some mills, with a tan-yard and a distillery, in the vicinity. It is also a mart for the lead-mine country.

I had now ascended one hundred and seventy miles from the junction of the Ohio. This had required over twenty-two days, which gives an average ascent of between seven and eight miles per day, and sufficiently denotes the difficulty of propelling boats up this stream by manual labor.

At Herculaneum I was introduced to M. Austin, Esq.—a gentleman who had been extensively engaged in the mining business while the country was yet under Spanish jurisdiction, and who was favorably known, a few years after, as the prime mover of the incipient steps to colonize Texas. Verbal information, from him and others, appeared to make this a favorable point from which to proceed into the interior, for the purpose of examining its mineral structure and peculiarities. I therefore determined to leave my baggage here until I had visited the territorial capital, St. Louis. This was still thirty miles distant, and, after making the necessary preparations, I set out, on the 26th of the month, on foot. In this journey I was joined by my two compagnons de voyage from Pennsylvania and Maryland. We began our march at an early hour. The summer had now assumed all its fervor, and power of relaxation and lassitude on the muscles of northern constitutions. We set out on foot early, but, as the day advanced, the sun beat down powerfully, and the air seemed to owe all its paternity to tropical regions. It was in vain we reached the summit land. There was no breeze, and the forest trees were too few and widely scattered to afford any appreciable shade.

The soil of the Missouri uplands appears to possess a uniform character, although it is better developed in some localities than in others. It is the red mineral clay, which, in some of its conditions, yields beds of galena throughout the mine country, bearing fragments of quartz in some of its numerous varieties. In these uplands, its character is not so well marked as in the districts further west; geologically considered, however, it is identical in age and relative position. The gullied character of the soil, and its liability to crumble under the effect of rain, and to be carried off, which was first noticed at Cape Girardeau, is observed along this portion of the river, and is most obvious in the gulfy state of the roads.

What added greatly to our fatigue in crossing this tract, was the having taken a too westerly path, which gave us a roundabout tramp. On returning to the main track, we forded Cold river, a rapid and clear brook; a little beyond which, we reached a fine, large, crystal spring, the waters of which bubbled up briskly and bright, and ran off from their point of outbreak to the river we had just crossed, leaving a white deposit of sulphur. The water is pretty strongly impregnated with this mineral, and is supposed to have a beneficial effect in bilious complaints. The scenery in the vicinity of the spring is highly picturesque, and the place is capable of being made a delightful resort.
