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.
