July 17th Tuesday, we concluded to 〈Stay〉 lay by to day to fix the Longitude, and get the Cronometer right, (She run down Day before yesterday), Several men out hunting to day Capt. Lewis rode out to Neesh-nah-ba-to na Creek [1] which passes thro. the Prarie (on which there is Some few trees) within [blank] Mile of the Missoureis, wind from the S E. Several of the party have tumers of different Kinds Some of which is verry troublesom and dificuilty to cure. I took a meridian altitude (43° 27°) which made the Lattitude of this place 40° 27' 6" 4/10 North.— (The Ball Hills 〈run〉 bear N 25° W for 30 mes. The bend on L. S. passing the Isd. on the right Side is N. 28° W. 4 ms.) Took equal altitudes

Cap Lewers returned, Saw Some hand Som Countrey, the Creek near the high land is rapid and nearly as muddy as the river, & rising Gutrich [Goodrich] caught two verry fat Cat fish G Drewyer Kill'ed 3 Deer, & R Fields one, a puff of wind brought Swarms of Misquitors, which disapeared in two hours, blown off by a Continuation of the Same brees.
Bald Pated Prarie July 17th, Tuesday 1804 We Concluded lay by at this place to day to fix the Lattitude & Longitude of this place to Correct the cromometer run down Sunday) Several men out by day light hunting Capt. Lewis Concld. to ride out to Neesh-nah-ba-to-na Creek which passes under the ball hills near this place and at one place a little above this Camp is within 300 〈miles〉 yards of the Missouris on this Creek grows Some few trees of oake walnut & mulberry. I took Meridian altitude of ☉ L. L. (43° 27') which made the Lattitude 40° 27' 5"4/10 North— wind from the South E. Several of the party much aflicted with tumers of different Kinds, Som of which is verry troublesom and dificuelt to cure. Capt. Louis returned in the evening. he Saw Som hand Some Countrey & Says that the aforesaid Creek is rapid muddey and running— [NB: running] This Creek which is at 10 or 12 [NB: where he saw it] from its mouth, within 300 yds of the river [NB: Missi ] is at least 16 foot Lower than the river— The high Lands from our Camp in this Bald Pated Prarie bears N 25° W. up the R.
