The banks consisted of dark alluvion ten to fifteen feet above the water, bearing a dense growth of trees and shrubbery.

The plunging of these banks into the stream often sounded like thunder.

With every exertion, we advanced but five miles the first day, and it was a long July day.

As evening came on, the mosquitos were in hordes.

It was impossible to perform the offices of eating or drinking, without suffering the keenest torture from their stings.
The second day we ascended six miles, the third day seven miles, the fourth day six miles, and the fifth eight miles, which brought us to the first settlement on the Missouri shore, called Tyawapaty Bottom.
