July 15th Sunday 1804.    a heavy fog this morning which Detained us untill 7 oClock, put Drewyer Sgt.

This evening I discovered that my Chronometer had stoped, nor can I assign any cause for this accedent; she had been wound up the preceding noon as usual. This is the third instance in which the instrument has stopt in a similar manner since she has been in my possession, tho' the fi[r]st only since our departure from the River Dubois.    in the two preceding cases when she was again set in motion, and her rate of going determined by a series of equal altitudes of the ☉ taken for that purpose, it was found to be the same precisely as that mentioned in the preliminary remarks [i.e., July 22, 1804, below] to these observations, or 15 s & 5 tenths too slow in 24 h—as her rate of going after stoping, and begin again set in motion has in two instances proved to be the same, I have concluded, that whatever this impediment may procede from, it is not caused by any material injury which her works have sustained, and that when she is in motion, her error on mean time above stated, may be depended on as accurate. In consequence of the chronometer's having thus accedentally stoped, I determined to come too at the first convenient place and make such observations as were necessary to ascertain her error, establish the Latitude & Longitude, and determine the variation of the nedle, in order to fix a second point of departure.    accordingly on [see Lewis's observation for July 16 below, where this note continues]


Sunday July 15th 1804.    a foggy morning which Detained us untill 7 oClock, Drewyer & Sgt. Floyd went on Shore.    we proceded on till Breakfast    af[ter] I went on Shore with Capt. Clark on the South Side    we Saw fresh Sign on bank of Elk.    crossed a creek named faun Creek [10] which came in on the South Side of Missouris.    we walked on over a Ridge    came to high large praries & hills.    we walked on    found Some cherries near a handsome Spring River named cherry Run, at which we drank at    the forks then followed it or one branch to the head which came out of a ridige which joined the praries, and went up on a high R. Ridge of prarie where we could See all around for a long distance in the open praries or as far as our eyes could behold, and on the opposite Side of the Missouris we Saw a large & extensive prarie which looked verry handsome, we walked along the hill prarie    came to a large Creek called ne-ma-haw Creek whic is about 30 yds. wide    we delayed their till the boat came in Site then crosed & went on to a point where the Boat came & Camped, the flanking party who were with the horses did not join us this night, Jo. Fields went out on the North Side & killed a Deer.—    we found plenty of ripe grapes along the Bottoms.


Sunday July 15th 1804    Set out at Six oclock A. m    pased a Creek on the South〈e〉 Side Called Plumb Run    water verry Strong    passed a Creek on the South Side Called Nemahaw Creek    it is about 30 yards wide    the Land is High and Good.    encamt on the South〈e〉 Side


Sunday 15th.    We got under way at six o'clock; passed a creek [11] on the south side; and gathered some ripe grapes. There is high land and prairies on this side. Captain Clarke and two men went by land. At the head of an island, called Elk island, we found some pummice stone among the drift wood. We passed a creek on the south side, called Na-ma-ha, and encamped on the same.


Sundy 15    the Morning was foggy    had to wait Untill it went off    Passd. the River namd. Nishnay Baton [12]    at 3 Oclock passd. the little Mohaugh    Got to Camp [13] on the Mohaugh prarie.    Roed. 11 Miles

Sunday July 15th    The morning being foggy, we had to waite 'till it cleared away, at 9 o'Clock A. M. we set off, and passed a River called Nishna Balon, at 3 oClock P. M. passed the little Mahaw River; and encamped at the Mahaw Priari, having rowed 11 Miles this day—    The little Mahaw River lies on the South side of the Mesouri.—

1. The first course is in Clark's hand; the remainder of these July 15 courses and distances are by Lewis. This is probably because Clark was ashore much of the day. The second entry, S. 75 W., disagrees with the Codex A course, given as N 70° W. There are also other variations. (back)
2. One of them was Ordway. (back)
3. In southeastern Nemaha County, Nebraska. Two of the streams were probably later Beadow Creek and Deroin creeks. MRC map 20; MRR map 56. (back)
4. The Little Nemaha reaches the Missouri River in Nemaha County, a little below the present town of Nemaha. MRC map 20; MRR map 56. (back)
5. This last sentence is written at right angles to the rest of the entry, over the rest, but appears to be part of the entry. Clark ran out of space at the bottom of the page. The camp, according to the present course of the Missouri, would be in Nehama County, somewhat above the present town of Nemaha. Opposite is Atchison County, Missouri. MRC map 20; MRR map 56. (back)
6. The "pea Vine" may refer to Amphicarpa bracteata (L.) Fern., hog peanut, which is a common species with a vining habit typically found in the area described. "Rich weed" is observed correctly in its appropriate moist, shaded streamside habitat. Steyermark, 953. (back)
7. They were now seeing the eastern margin of the Great Plains; the characteristic treelessness was new to them and worthy of comment. The area along the Missouri is more wooded today because prarie fires have been controlled. (back)
8. Lewis's observation from Codex O. (back)
9. Probably later Morgan Island. MRC map 20; MRR map 56. (back)
10. Clark mentions but does not name Ordway's two creeks; Floyd calls one (perhaps Ordway's second) "Plumb Run," which may be either Beadow or Deroin creeks, in southeastern Nemaha County, Nebraska. (back)
11. Perhaps either Beadow or Deroin creeks, southeastern Nemaha County, Nebraska, noticed but not named by Clark. (back)
12. The Nishnabotna River, which everyone else says they passed the previous day. (back)
13. In Nemaha County, somewhat above present Nemaha. (back)
