As the Indians who were on their way down the Missouri had a number of spare horses with them, I thought it probable that I could obtain some of them and therefore desired the chief to speak to them and inform me whether they would trade. They gave no positive answer but requested to see the goods which I was willing to give in exchange. I now produced some battle axes which I had made at Fort Mandan, with which they were much pleased. Knives also seemed in great demand among them. I soon purchased three horses and a mule.
