When Burt Hawkins and his two friends left St. Louis, late in summer or early in the fall, each rode a mule or horse, besides having two pack animals to carry their supplies and peltries. They followed some faintly marked trail, made perhaps by the hoofs of their own animals, and did not reach their destination for several weeks. When they halted, it was among the tributaries of the Missouri, which have their rise in the Ozark range in the present State of Missouri.
