The expedition’s pause at the Three Forks of the Missouri produced a revealing cross-section of journal styles. With Captain Clark recovering from illness and the men occupied dressing skins, the day’s events were modest — but each narrator filtered them through a distinct lens. Reading Lewis, Clark, and Whitehouse against one another exposes how the same camp could yield a single sentence, a paragraph of routine, or a small essay in zoology.
Three Registers, One Camp
Clark’s entry is the briefest he could plausibly write. He notes the weather, his own convalescence, the latitude derived from two meridian altitudes, and the men’s labor:
A fair morning wind from the North I feel my Self something better to day, made some Celestial observations took two Merdn. altitudes which gave for Latd. 45° 22′ 34″ N men all dressing Skins &c.
The terseness reflects both his weakened state — Lewis confirms he is “perfectly clear of fever but still very languid” — and Clark’s general preference for the cartographer’s economy: position, weather, condition of the party.
Whitehouse, writing as an enlisted man, expands Clark’s skeleton with the practical detail of camp life. He echoes the latitude reading almost exactly (“45°, 22″, 34″ 5/10 North”), suggesting he had access to the captains’ figures or copied them from a shared source. He then supplies measurements absent from both officers’ entries — the widths of the three forks at sixty, sixty, and forty yards — and closes with the hunters’ return: two fat buck deer and “a curious long leged redish couloured crain.”
The Sandhill Crane: Whitehouse’s Curiosity, Lewis’s Specimen
That crane is the day’s most telling cross-narrator artifact. Whitehouse sees it as a curiosity, worth a single descriptive line. Lewis devotes a full paragraph to it, identifying the bird, observing its behavior, and staging a small drama of capture and release:
the hunters brought in a living young sandhill crane it has nearly obtained it’s growth but cannot fly; they had pursued it and caught it in the meadows. it’s colour is precisely that of the red deer.
Lewis’s eye for comparative coloration — matching the juvenile crane’s plumage to the long-tailed red deer he has just described — is characteristic of his naturalist’s habit of cross-referencing species within a single entry. He continues:
this young animal is very ferce and strikes a severe blow with his beak; after amusing myself with it I had it set at liberty and it moved off apparently much pleased with being releived from his captivity.
The anthropomorphic flourish (“much pleased”) is uncharacteristic of Lewis’s usually clinical descriptions and hints at the affection the captain felt for the bird after “amusing” himself with it. Whitehouse, by contrast, registers no such interaction — the crane in his account is simply brought into camp with the venison, an item of game rather than a subject of observation.
Lewis’s Catalogue of the Plains
Where Clark records position and Whitehouse records yield, Lewis records ecosystem. The same entry sweeps from deer to crane to fish (“some of which we take to be trout but they will not bite at any bate we can offer them”) to kingfishers, summer ducks, mallards with their young, grasshoppers, crickets, and finally a remarkable note on the prairie ant:
there is also in these plains a large ant with a redish brown body and legs, and a black head and abdomen; they construct little perimids of small gravel in a conic shape, about 10 or 12 inches high without a mixture of sticks and with but little earth.
Neither Clark nor Whitehouse mentions the ants, the kingfishers, or the absent summer duck. Lewis even back-corrects his own record, noting that the mallard ducklings were “first seen with their young on the 20th inst. and I forgot to note it.” This impulse — to retroactively repair the natural history of the journey — is entirely his own and finds no parallel in his companions’ entries for the day.
Patterns of Borrowing and Independent Detail
The shared latitude figure between Clark and Whitehouse confirms what scholars have long observed: the enlisted journalists drew on the captains’ navigational data. Yet Whitehouse’s river-width measurements and his color description of the crane (“redish couloured”) are independent contributions, not derivable from either captain’s entry as preserved. The day at the Three Forks thus shows the expedition’s documentary apparatus working in three modes at once — Clark’s positional shorthand, Lewis’s encyclopedic field notebook, and Whitehouse’s hybrid of borrowed figures and firsthand camp reportage.
