"this being the part of the Missouri the Kanzas nation resort to at this season of the year for the purpose of robbing the perogues passing up to other nations above, we have every reason to expect to meet with them, and agreeably to their common custom of examining every thing in the perogues and takeing what they want out of them, it is probable they may wish to take those liberties with us, which we are deturmined not to allow of and for the Smallest insult we shall fire on them. ... we met three large boats bound to the Yanktons and Mahars ... those young men received us with great friendship and pressed on us Some whisky for our men, Bisquet, Pork and Onions, & part of their Stores, ... our party received a dram and Sung Songs untill 11 oClock at night in the greatest harmoney.
