This was another
mart of the lead mines.
I determined to land definitively at this point, purposing to visit the
mines, after completing my ascent by land to St. Louis. It was now the
23d of July, the whole of which, from the 1st, we had spent in a
diligent ascent of the river, by setting pole and cordelle, from the
junction of the Ohio--a distance of one hundred and seventy miles. We
were still thirty miles above St. Louis.
I have detailed some of the incidents of the journey, in order to denote
the difficulties of the ascent with barges prior to the introduction of
steam, and also the means which this slowness of motion gave me of
becoming acquainted with the physical character of this river and its
shores. A large part of the west banks I had traveled on foot, and
gleaned several facts in its mineralogy and geology which made it an
initial point in my future observations. The metalliferous formation is
first noticed at the little chain of rocks. From the Grand Tower, the
western shores become precipitous, showing sections and piled-up
pinnacles of the series of horizontal sandstones and limestones which
characterize the imposing coast.
