Two Registers, One River Bend
The entries from 4 August 1804 offer a striking demonstration of how differently the Corps of Discovery’s narrators handled a single day on the Missouri near the Soldier River. William Clark produces two overlapping accounts—a field draft and an expanded version—dense with topographic detail, hydrological observation, and ethnographic memory. Patrick Gass, by contrast, compresses the entire day into four sentences. Both men describe the same campsite, the same missing man, and the same deer; yet their entries function as nearly opposite documents.
Clark opens with weather, noting that
at 7 oClock the heavens darkened and a violent wind from the N W. Suckceeded which lasted about an hour, with a little rain.
Gass omits the storm entirely, beginning simply: “had a fair day.” The contradiction is not factual—Clark’s expanded version clarifies that the squall struck at seven o’clock the previous night, leaving the morning “clear Sereen and Cool.” Gass, writing retrospectively, has folded the meteorology into a single judgment about the day’s character. Clark, the cartographer-officer, treats weather as a discrete event requiring its own timestamp.
Cruzatte’s Trading House and the Three Ponds
Clark devotes considerable space to a landmark Gass ignores altogether: the ruins of an old trading post on the larboard side. In his first draft Clark notes briefly that “one of our Crew passed 2 years P. C tradeing with the Mahar; & Ponies.” The expanded version names the man explicitly:
the remains of an old Tradeing establishment L. S. where Petr. Crusett one of our hands Stayed two years & traded with the Mahars
This is Pierre Cruzatte, the boatman and fiddler whose Omaha-language fluency would prove valuable upriver. Clark’s two passes at the same sentence—first abbreviating “P. C,” then writing the name in full—suggest a working journalist refining his record for later readers. Gass, who certainly knew Cruzatte personally, records none of this. His role as sergeant did not require him to track ethnographic intelligence; Clark’s did.
Clark is similarly careful about hydrology. He identifies a creek as “the outlett of 3 ponds, which recved ther water from the Smaller Streams running from the hills,” and in revision elaborates that the ponds “are fed by Springs & Small runs from the hills.” Gass reduces the entire system to “a creek on the south side, which came out of ponds.” The information is technically equivalent; the precision is not.
The Missing Man
Both narrators register the day’s most significant human event: the absence of Private Moses Reed. Gass writes only that “One of our men went out this morning and did not return.” Clark, in both drafts, names him and explains:
Reed the man who went back to the Camp of last night for his Knife has not Come up this evening
The discrepancy is telling. Gass presents Reed as having simply wandered off in the morning. Clark records the cover story Reed offered—that he was returning to the previous night’s camp to retrieve a knife. Within days the expedition would conclude that Reed had deserted, and a detachment under Drouillard would be sent to bring him back. Clark’s version preserves the pretext that made the desertion possible; Gass’s version, perhaps written with hindsight, strips it away.
The arrival of fresh meat receives parallel but unequal treatment. Gass notes that “another came to us and brought a deer.” Clark logs simply: “1 Buck Killed to daye.” Neither narrator names the hunter. Both encamp at the same beaver lodge on the larboard shore.
Patterns of Attention
The 4 August entries illustrate a pattern visible throughout the journals: Clark records redundantly and revises in place, producing a layered manuscript in which the same observation appears in successive forms. Gass writes once and writes briefly. Clark notices pumice stone “of various Sizes” along the banks—a geological detail Gass does not mention. Clark counts wild geese; Gass does not. Where their accounts converge—on the camp, the deer, the absent man—Gass’s terseness functions almost as a checksum against Clark’s expansive log, confirming the bare facts while leaving the interpretive work to the captain’s pen.
