September 30. The wind was this morning very high from the southeast, so that we were obliged to proceed under a double-reefed mainsail, through the rain. The country presented a large low prairie covered with timber on the north side; on the south, we first had high barren hills, but after some miles it became of the same character as that on the opposite side. We had not gone far when an Indian ran after us, and begged to be carried on board as far as the Ricaras, which we refused: soon after, we discovered on the hills at a distance, a great number of Indians, who came towards the river and encamped ahead of us.
