Sept. 12th. Commenced our march at seven o'clock. Passed very ruff [rough] flint hills. My feet blistered and very sore. I stood on a hill, and in one view below me saw buffalo, elk, deer, cabrie, and panthers. Encamped on the main [Cottonwood] branch of Grand [Neosho] river, which had very steep banks and was deep. Dr. Robinson, Bradley, and Baroney arrived after dusk, having killed three buffalo, which, with one I killed, and two by the Indians, made six; the Indians alleging it was the Kans' hunting ground, therefore they would destroy all the game they possibly could. Distance 18 miles.[I-60]

Sept. 13th. Late in marching, it having every appearance of rain. Halted to dine on a branch of Grand river. Marched again at half past two o'clock, and halted at five, intending to dispatch Dr. Robinson and one of our Pawnees to the village to-morrow. Killed six buffalo, one elk, and three deer. Distance nine miles.[I-61]

Sunday, Sept. 14th. The doctor and Frank, a young Pawnee, marched for the village at daylight; we at half past six o'clock. Halted at one o'clock. On the march we were continually passing through large herds of buffalo, elk, and cabrie; and I have no doubt that one hunter could support 200 men. I prevented the men shooting at the game, not merely because of the scarcity of ammunition, but, as I conceived, the laws of morality forbid it also. Encamped at sunset on the main branch [Cottonwood] of White river, hitherto called Grand river. Killed one buffalo and one cabrie. Distance 21 miles.[I-62]

Sept. 15th. Marched at seven o'clock; passed a very large Kans encampment, evacuated, which had been occupied last summer. Proceeded on to the dividing ridge between the waters of White river and the Kans [more exactly, from basin of the Cottonwood to that of the Smoky Hill]. This ridge was covered with a layer of stone, which was strongly impregnated with iron ore, and on the W. side of said ridge we found spa springs. Halted at one o'clock, very much against the inclination of the Osage, who, from the running of the buffalo, conceived a party of Kans to be near. Killed two buffalo. Distance 18 miles.[I-63]

Sept. 16th. Marched late, and in about 4½ miles' distance came to a very handsome branch of water [Hobbs branch of Gypsum creek], at which we stopped and remained until after two o'clock, when we marched and crossed two branches [main Gypsum and Stag creeks]. Encamped on a third. At the second [Gypsum] creek, a horse was discovered on the prairie, when Baroney went in pursuit of him on a horse of Lieutenant Wilkinson, but arrived at our camp without success. Distance 13 miles.[I-64]

Sept. 17th. Marched early and struck the main S. E. [Smoky Hill] branch of the Kans river at nine o'clock; it appeared to be 25 or 30 yards wide, and is navigable in the flood seasons. We passed it six miles to a small branch to breakfast. Game getting scarce, our provision began to run low. Marched about two o'clock, and encamped at sundown on a large branch [Mulberry creek]. Killed one buffalo. Distance 21 miles.[I-65]

Sept. 18th. Marched at our usual hour, and at twelve o'clock halted at a large branch [Saline river] of the Kans [Smoky Hill], which was strongly impregnated with salt. This day we expected the people of the [Pawnee] village to meet us. We marched again at four o'clock. Our route being over a continued series of hills and hollows, we were until eight at night before we arrived at a small dry branch [of Covert creek]. It was nearly ten o'clock before we found any water. Commenced raining a little before day. Distance 25 miles.[I-66]
