21. Head of Coon Creek.--At five miles the road forks, one following the river, the other a "short cut" "dry route" to Fort Atkinson, where they unite on the river. The country rises for ten miles on the dry route, then descends to the river, and is covered with the short buffalo-grass. No wood at camp. 18. Arkansas River.--The road passes over an undulating and uninteresting prairie, with but little vegetation. The water in dry weather is in pools. 19. Arkansas River, at Fort Atkinson.--The road runs over a similar country to that of yesterday, with no wood near; plenty of buffalo-chips for cooking, and good grass. 18-3/4. Arkansas River.--At 4-1/2 miles the road ascends a bluff covered with thick buffalo-grass. On the river is heavy bottom-grass. At 17 miles pass a ford. Grass good at camp. 19-1/4. Arkansas River.--The road is sandy for 14 miles, but not deep except in places; thence to camp it is good. Good camp. 22. Arkansas River.--Country prairie, covered with short buffalo-grass. Good camp. 22. Arkansas River.--The road is fine, crossing several dry-beds of creeks, along which are seen a few scattering trees. Good camp on a dry creek near the river. 24. Arkansas River.--The road runs over a barren plain at the foot of the main plateau, and crosses two dry creeks near the camp, on which are cottonwood-trees. Plenty of wood at camp. 21. Arkansas River.--The road follows the base of the hills at from one to three miles from the river. Good camp. 20. Arkansas River.--At seven miles the road strikes the "Big Timbers," where there is a large body of cottonwood; thence for three miles the road is heavy sand. Good camps along here. 13. Arkansas River.--At one mile the road passes some old houses formerly used as a trading-post. Here terminates the "Big Timbers." Coarse grass at the camp. 15. Arkansas River.--At three miles the road passes the mouth of Purgatoire Creek. Camp is below Bent's Fort. Good grass here. 24. Arkansas River.--Pass Bent's Fort. The grass is excellent in the vicinity of the fort, but after this it is not so good. The road runs over a high and considerably broken country. Good camp. 11. Arkansas River.--Opposite the mouth of the Apishpa Creek; good camp. The Huerfano Mountains and Spanish Peaks are in sight from the camp. The "Cherokee Trail" comes in from Arkansas near Bent's Fort, and leads to the gold diggings at Cherry Creek. 9. Arkansas River.--Opposite the mouth of the Huerfano Creek. Good camp, and a ford opposite Charles Audebee's house.
