The journals of 29 July 1806 capture the Corps of Discovery in two widely separated parties, each pressing toward the planned reunion below the confluence. Meriwether Lewis and his men, including Patrick Gass and John Ordway, are descending the Missouri through the white-cliff country above the Marias. William Clark, with a separate detachment, is far to the south on the Yellowstone (the Rochejhone), arriving at the mouth of the Tongue River. Reading the four entries side by side reveals how a single date fractures into distinct experiences — and how the enlisted men’s accounts orbit Lewis’s authoritative narrative.
The Bighorn Hunt and the Specimens for Washington
The Missouri-party narrators converge on one event: the killing of bighorn sheep in the broken clay country and the preservation of specimens for shipment east. Lewis records the scientific particulars with characteristic precision:
on our way today we killed 9 bighorns of which I preserved the skins and skeletons of 2 females and one male; the flesh of this aninmal is extreemly delicate tender and well flavored… the eye is large and prominant, the puple of a pale sea green and iris of a light yellowish brown colour.
Gass, writing in his more compressed sergeant’s register, reports the same hunt but rounds the totals differently and emphasizes the destination of the specimens:
Captain Lewis had four of these animals skeleton-ized, to take with him to the seat of Government of the United States.
Ordway, notably, uses nearly identical phrasing — “Capt Lewis had them Scallintinized [skeleton-ized]… to take to the Seat of government” — and even repeats the action a second time for the females. The verbal echo between Gass and Ordway, both rendering the technical verb phonetically, suggests either shared conversation around the evening fire or a common reliance on Lewis’s stated intention as the framing fact of the day. Where Lewis writes as naturalist, his sergeants write as chroniclers of the captain’s program.
Two Rivers, Two Weathers
The most striking divergence is meteorological and geographical. Lewis opens with a miserable night:
Shortly after dark last evening a violent storm came on from N. W. attended with rain hail Thunder and lightning which continued the greater part of the night. no having the means of making a shelter I lay in the water all night.
Clark, hundreds of miles south, records the same weather system from its eastern edge: “a Slight rain last night with hard thunder and Sharp lightening accompanied with a violent N. E. wind.” The compass directions differ — N.W. for Lewis, N.E. for Clark — but the storm appears to be a shared continental event, a rare moment when the sundered captains feel the same sky. Gass and Ordway, traveling with Lewis, mention only the resulting rain and muddy water, missing the captain’s drenched, shelterless night entirely. Lewis’s private suffering does not reach the enlisted record.
Clark alone documents the Yellowstone landscape, identifying what he calls the Lazeka or Tongue River and noting its undrinkable water:
finding that its water So muddy and worm as to render it very disagreeable to drink, I crossed the rochejhone and encamped on an island close to the Lard. Shore. The water of this river is nearly milk worm very muddy and of a lightish brown Colour.
His attention to coal seams in the bluffs, the width of the channel, the catfish and soft-shell turtle taken that evening, and the inferred character of the upstream country (“an open one where the water is exposed to the Sun which heats it”) shows the geographer-captain working alone, without the cross-checking presence of a second journalist.
Register and Redundancy
Lewis declines to redescribe the white cliffs, citing his outbound entry: “as I have been very particular in my discription of the country as I ascended this river I presume it is unnecesssesary here to add any-thing further.” Ordway, by contrast, supplies precisely the picturesque detail Lewis omits — “the white walls resembling ancient towns & buildings” — preserving for the return voyage an image Lewis felt he had already exhausted. Gass, ever the pragmatist, reduces the same terrain to “a range of high rough hills.” The three Missouri-party voices thus distribute the descriptive labor: Lewis the scientist, Ordway the scene-painter, Gass the bookkeeper of distances and kills. Clark, working without that ensemble, must do all three jobs himself — and his Yellowstone entry, dense with hydrology, geology, and ichthyology, shows him doing exactly that.
