August 10, 1806, finds two detachments of the Corps of Discovery descending the Missouri toward their planned reunion. The day’s tasks are routine — finishing repairs to the white pirogue, dressing and smoking deer skins, loading the craft, and pushing on downriver before nightfall. What makes the date worth examining is not the events themselves but the striking divergence in how four narrators choose to record them.
A Shared Narrative of Departure
Three of the four journals — those of Lewis, Ordway, and Gass — track the day’s progress along nearly identical lines, agreeing on the sequence of repairs, the afternoon weather, the hour of embarkation, and the misery of the evening’s insects. Lewis writes that the repairs "were compleated by 2 P.M." and that "at 5 P.M. got under way," while Gass records that the party "got the periogue completed, loaded our craft, and at four o’clock proceeded on." Ordway splits the difference: "about three P. M. we put the canoes in the river, and loaded up and about 4 we Set out."
The pattern of agreement extends to the campsite. Both Lewis and Gass identify the location with reference to White-earth River. Gass adds a detail Lewis omits — that this was "the same bottom, where we encamped on the 21st April 1805" — suggesting Gass either consulted his earlier notes or had a strong memory of the outbound journey. Ordway, characteristically, gives only the bare directional fact: "Camped on Sd Side."
On the mosquitoes, the three converge in tone but vary in intensity. Lewis calls them "more than usually troublesome." Gass escalates: "the musquitoes here were very bad indeed." Ordway, who often reserves his most feeling prose for personal discomfort, surpasses both:
the musquetoes verry troublesome indeed, we could not all this night git a moment quiet rest for them.
The register difference is telling. Lewis maintains the captain’s measured tone; Gass, the carpenter-sergeant, speaks plainly; Ordway, the sergeant whose journal frequently registers the enlisted men’s bodily experience, gives the night a sleepless human texture the officers’ entries lack.
Clark Apart: A Botanist’s Day
William Clark, encamped with the separate Yellowstone detachment, writes a journal entry of an entirely different character. Where the others document a journey, Clark documents a place. He notes only briefly that the elk meat was hung to dry, that the wind "blew hard from the East all day," and that Shields killed "a black tail deer & an antilope." He then turns to natural history and stays there for the bulk of his entry.
Clark’s description of an unfamiliar cherry occupies the heart of the day’s record. He observes the plant with a careful taxonomist’s eye:
the Stem is compound erect and subdivided or branching without any regular order. it rises to the hight of 8 or 10 feet Seldom putting out more than one Stem from the Same root not growing in cops as the Choke Cherry does.
He notes leaf shape, serration, color, the absence of pubescence, the "globular berry about the Size of a buck Shot of a fine Scarlet red," and the distinctive swelling peduncle. He admits the limits of his observation — "I have never Seen it in blume" — a scholarly caution worth noting. Clark also records that the men dug "the root which the Nativs call Hankee and the engagees the white apple," preserving both an Indigenous and a French-Canadian voyageur term for what is almost certainly the prairie turnip (Psoralea esculenta).
What the Comparison Reveals
The August 10 entries illustrate a dynamic recurrent throughout the expedition’s later journals. When Lewis and Clark are physically separated, their entries cease to mirror one another and reveal their distinct preoccupations: Lewis tracks the logistics of movement, while Clark, freed from the daily duties of joint command, develops the descriptive natural-history passages for which his later journals are valued. Meanwhile, Gass and Ordway — whose entries on this date plainly track Lewis’s party — provide the corroborating enlisted-man’s perspective, with Gass tending toward terse summary and Ordway toward felt experience.
That three of four narrators on the same date produce essentially the same paragraph, while the fourth produces a botanical monograph, is itself a piece of evidence about how the expedition’s documentary record was constructed: by parallel observers in shared circumstances, and by separated observers whose journals diverge in proportion to the distance between them.
