The journals of July 23, 1805, offer an unusually rich opportunity for cross-narrator comparison. Captain Clark has detached with a small party to push ahead in search of the Shoshone, while Lewis remains with the canoes laboring up a swift, island-choked Missouri. Four pens — Lewis, Clark, Sergeant Gass, and Private Whitehouse — record the same day, and the divergences in detail and register illuminate how information traveled, and was filtered, within the Corps.
A Shared Skeleton, Four Levels of Detail
All four narrators agree on the day’s essentials: Clark’s departure overland, the rapid current, the multitude of islands, the wide valley flanked by mountains, and a day’s progress of roughly 24 to 25 miles. Gass, characteristically economical, compresses the day into a few sentences:
The course of the river all day was nearly from the south, through a valley of 10 or 12 miles wide. The mountains are not so high nor so rocky, as those we passed…. We encamped on an island, having made 24 miles.
Clark’s own entry is similarly spare, befitting a man writing on the trail after a long march:
I Set out by land at 6 miles overtook G Drewyer who had killed a Deer. we killed in the Same bottom 4 deer & a antelope & left them on the river bank for the Canoes proceeded on an Indian roade through a wider Vallie which the Missouri Passes about 25 miles & Camped on the bank of the river
Lewis, by contrast, expands the same events into an extended natural-history essay, cataloguing the geology (“low bluffs of yellow and red clay with a hard red slate stone intermixed”), the underbrush (“narrow & broad leafed willow rose and Currant bushes”), and the botany of thistles, wild onions, garlic, and flax. Whitehouse occupies a middle register — more expansive than Gass, more personal than Clark — and is the only narrator to confess physical misery: “the Musquetoes verry troublesome. I cannot keep them out of my face at this time.”
Whitehouse’s Creek: A Naming Recorded by Only One Pen
One of the day’s most striking asymmetries concerns the naming of a tributary. Lewis records the event with care:
passed a large creek on Lard. side 20 yds. wide which after meandering through a beautifull and extensive bottom for several miles nearly parallel with the river discharges itself opposite to a large cluster of islands which from their number I called the 10 islands and the creek Whitehous’s Creek, after Josph. Whitehouse one of the party.
Gass mentions “a small river on the south side” without name; Whitehouse himself notes “the mouth of a Small River which came in behind an Island on the South Side” — apparently unaware, at the moment of writing, that the stream had just been christened in his honor. Clark does not mention the creek at all. The episode is a useful reminder that the captains’ acts of nomenclature were not always communicated downstream to the enlisted men in real time, and that Whitehouse’s journal, though often paralleling Lewis’s in phrasing, is not simply a copy.
Shared Phrasing and Independent Observation
Several passages suggest Whitehouse had access to information from Lewis or to a shared oral briefing. Both men note the hoisting of flags as an Indian-recognition signal, the midday halt to dry wet cargo, the abundance of wild onions, the flax going to seed, and the thistles in bloom. Lewis writes that he “halted rearther early for dinner today than usual in order to dry some articles”; Whitehouse echoes, “we delayed to dry the articles wh[ich] is wet in the canoes.” Yet Whitehouse adds details Lewis omits — the fatigue of the party (“the party in general much fatigued”), the plenty of beaver, the pine on the hillsides at a distance — suggesting genuine independent observation rather than wholesale copying.
Gass, meanwhile, offers a detail neither captain records: that Clark’s party “killed four deer and a cabre, and left the skins and meat on the horse, where we could easily find them.” Clark mentions leaving the meat on the riverbank; Lewis confirms picking up four deer; only Gass specifies a horse as the cache marker, an example of the sergeant’s eye for logistical particulars.
The Search for the Shoshone
Underlying the day’s botanical and geographical observations is mounting anxiety. Whitehouse states the strategic purpose plainly: “Cap! Clark and 3 men Set out in order to go on to the 3 forks, expecting to find the Snake nation, near that place.” Clark himself, scanning the ground, notes pointedly: “I Saw no fresh Sign of Indians to day.” Lewis’s order to hoist the flags — so that any watching Shoshone “might discover that we were not Indians, nor their enemies” — belongs to the same preoccupation. Read together, the four entries trace a single thread of expectation running beneath the surface of an otherwise routine day of upstream labor.
