By mid-July 1806 the Corps of Discovery had fractured into detachments scattered across hundreds of miles of country. The journal entries for July 18 read like four separate expeditions, and the contrast in voice, scale, and subject matter offers an unusually clear window into how each narrator understood his role as a record-keeper.
Lewis the Geographer, Clark the Naturalist
Lewis, ascending the Marias River with a small party, writes in the register of a topographer surveying contested ground. He names mountain ranges visible from an elevated plain — “the North mountains, the South mountains, the falls mountains and the Tower Mountain” — and frames the day’s march in terms of drainage divides and reconnaissance objectives. His closing sentence is unusually candid about the anxiety of his northern excursion:
I keep a strict lookout every night, I take my tour of watch with the men.
Clark, descending the Yellowstone, writes in a different mode entirely. Where Lewis abstracts the country into ranges and watersheds, Clark accumulates incident: two buffalo bulls swimming the river and dying on the far bank, Charbonneau thrown when his horse stepped “into a Braroe hole,” Gibson impaling his thigh on a burnt snag while mounting. Clark’s entry alternates between such accidents and connoisseurial appreciation of the landscape’s resources — currants “of an excellent flavour” with the purple variety “Superior to any I have ever tasted,” and rocks “well Calculated for grindstones.” His is the journal of a working captain assessing what the country can give and what it can take.
The Sergeants’ Registers
Ordway and Gass, traveling with Clark’s Yellowstone detachment and the portage party respectively, produce entries of markedly different character from the captains and from each other. Ordway’s prose has the loose, additive rhythm of a daily log: “Saw large gangues of buffaloe… Collins killed three deer. Saw great numbers of beaver and otter.” Where Clark generalizes, Ordway counts. And where the captains keep their own bodies out of the record, Ordway lets his in:
the Musquetoes and Small flyes are verry troublesome, my face and eyes are Swelled by the poison of those insects which bite verry severe indeed.
This is one of the few first-person bodily complaints in any narrator’s entry for the day — Clark dresses Gibson’s wound but does not mention his own discomfort; Lewis registers vigilance but not fatigue.
Gass’s entry, by contrast, is the shortest and most procedural of the four. Stationed near the Great Falls portage, he records a brief errand:
down with three of the men to the lower end of the portage to examine the periogue and deposit there, and found all safe. We took some tobacco out of the deposit, covered up all again, until the party should arrive with the canoes, and returned to camp.
The detail about tobacco is characteristic Gass: a small, practical fact (the cache was opened, partially used, and resealed) that neither captain bothered to record because neither was present. For the logistical history of the expedition’s caches, Gass’s terse sentences are often the only source.
Cross-Narrator Patterns
Several patterns emerge when the four entries are read together. First, none of the four narrators on this day appears to be copying or consulting another — a reminder that the famous overlaps between Lewis and Clark, or between Ordway and the captains, depend on physical proximity. With the party split four ways, each journal becomes genuinely independent.
Second, the register differences sharpen. Lewis interprets: when he sees smoke he would speculate, as Clark does, about its meaning. Clark, observing a smoke column rising “to the S. S. E in the plains,” offers two competing hypotheses — that the Crow have mistaken the party for Shoshone trading partners, or that they have taken them “to be their Enemy.” This kind of reasoned ethnographic speculation is largely absent from Ordway and entirely absent from Gass on this date.
Third, the captains and the sergeants divide cleanly on the question of the body. Clark records Gibson’s snag wound and Charbonneau’s bruises clinically, as injuries to subordinates. Ordway records his own swollen face. Gass records nothing of himself at all. Lewis admits only that he stands watch. Read together, the four entries demonstrate how rank, role, and audience shaped what each man considered worth setting down — and how much of the expedition’s daily texture survives only because four different pens were at work.
