Few Indians were found, and large flocks of prairie chickens, geese, ducks and sandhill cranes were frequently seen.
At the mouth of the Great Sioux River they were assured by the interpreter, M.

These pipe stone lands were by agreement among the Indians, far and near, declared to be neutral grounds, where hostile tribes often met peaceably upon the banks of Pipestone Creek to secure their caluments of peace.

It need only be stated that it was conducted with courage and judgment and was eminently successful in procuring a vast fund of information as to the character of our newly acquired possessions. The explorers ascended the Missouri River to its source in the Rocky Mountains and crossed the divide to the head waters of the Columbia, which empties into the Pacific Ocean in Oregon.
