able we made eighteen miles to-day. We
passed in the morning several islands, the largest of which is Buffaloe
island, separated from the southern side by a small channel which
receives the waters of Buffaloe creek. On the same side is Shepherd's
creek, a little beyond which we encamped on the northern side. The next
day we sailed along a large island called Otter island, on the northern
side, extending nearly ten miles in length, narrow but high in its
situation, and one of the most fertile in the whole river. Between it
and the northern shore, three small creeks, one of which has the same
name with the island, empty themselves. On the southern shore is a creek
twenty yards wide, called Ash creek. In the course of the day we met two
canoes loaded with furs, which had been two months on their route, from
the Mahar nation, residing more than seven hundred miles up the
river--one large raft from the Pawnees on the river Platte, and three
others from the Grand Osage river. At the distance of fifteen miles we
encamped on a willow island, at the entrance of the river Gasconade.
This river falls into the Missouri from the south, one hundred miles
from the Mississippi. Its length is about one hundred and fifty miles in
a course generally northeast through a hilly country. On its banks are a
number of saltpetre caves, and it is believed some mines of lead in the
vicinity. Its width at the mouth is one hundred and fifty-seven yards,
and its depth nineteen feet.

Here we halted for the purpose of hunting and drying our provisions, and
making the necessary celestial observations. This being completed, we
set sail on the 29th at four o'clock, and at four miles distance
encamped on the south-side, above a small creek, called Deer creek. The
next day, 30th, we set out early, and at two miles distant reached a
large cave, on the north, called Montbrun's tavern, after a French
trader of that name, just above a creek called after the same person.
Beyond this is a large island, and at the distance of four miles, Rush
creek coming in from the south, at eleven, Big-muddy river on the north,
about fifty yards wide; three miles further, is Little-muddy river on
the same side, opposite to which we encamped at the mouth of Grindstone
creek. The rain which began last night continued through the day,
accompanied with high wind and some hail. The river has been rising fast
for two days, and the country around appears full of water. Along the
side
