I had not yet put my foot ashore, when a fellow-passenger brought me a message from one of the principal merchants of the place, desiring me to call at his store, and aid him in the examination of some drugs and medicines which he had newly received. On reaching his store, I was politely ushered into a back room, where some refreshments were handsomely set out. The whole thing was, in fact, designed as a friendly welcome to a professional man, who came neither to sell nor buy, but simply to inquire into the resources and natural history of the country. At this trait of hospitality and appreciation in a stranger, I took courage, and began to perceive that the West might be relied on.
I found the town of Cape Girardeau situated on an elevation of rich, red, marly soil, highly charged with oxide of iron, which is characteristic of the best arable soils of the mine country. This soil appears to be very readily dissolved in water, and carried off rapidly by rains, which furnishes a solution to the deep gulfs and gorges that disfigure many parts of the cultivated high grounds. If such places were sown with the seeds of grass, it would give fixity to the soil, and add much to the beauty of the landscape.
July 9th. We resumed our journey up the rapid stream betimes, but, with every exertion, ascended only seven miles. The river, in this distance, preserves its general character; the Missouri shores being rocky and elevated, while the vast alluvial tracts of the Illinois banks spread out in densely wooded bottoms. But, while the Missouri shores create the idea of greater security by their fixity, and freedom from treacherous alluvions, this very fixity of rocky banks creates jets of strong currents, setting around points, which require the greatest exertions of the bargemen to overcome. To aid them in these exigencies, the _cordelle_ is employed. This consists of a stout rope fastened to a block in the bow of the barge, which is then passed over the shoulders of the men, who each at the same time grasp it, and lean hard forward.
July 10th. To me, the tardiness of our ascent, after reaching the rock formations, was extremely favorable, as it facilitated my examinations. Every day the mineralogy of the western banks became more interesting, and I was enabled daily to add something to my collection. This day, I picked up a large fragment of the pseudo pumice which is brought down the Missouri by its summer freshets. This mineral appears to have been completely melted; and its superficies is so much enlarged by vesicles filled with air, and its specific gravity thereby so much reduced, as to permit it to float in water. We encamped this evening, after an ascent of seven miles, at a spot called the Moccasin Spring, which is contained in a crevice in a depressed part of the limestone formation.
