|The Steamboat Dacotah|
The Dacotah was actually the 6th boat to arrive at the levee, and the date indicated on this way bill is not the day that it arrived, but rather the day the freight was unloaded. This boat actually belonged to the Coulson brothers, and was not a boat which belonged to T. C. Powers. My assumption is that some of the freight belonging to Powers was put on the landing at Coal Banks, and was then transported to Fort Benton on the Dacotah, thus explaining the reason why this is a Power way bill rather than a Coulson way bill.
Regardless of who this boat belonged to, this image was taken from the only extant photograph of the Dacotah.
