see if the canoes had come up that far, and came upon the
north branch about 2 miles above it. Here we discovered
that the people in the canoes had not found the note, and with
great difficulty, had proceeded 5 or 6 miles up the north
branch. In their return down one of the canoes was over-
turned ; a knapsack, shot-pouch and powder-horn lost, and
all the rest of the loading wet. We got down to the forks
about 12 o’clock, put all our baggage out to dry, and en-
camped for the night. Some hunters went out and killed 3
deer.
