The journal entries for December 11, 1805 present one of the starkest register contrasts in the expedition’s documentary record. Both Patrick Gass and William Clark are camped on the south side of the Columbia estuary, raising the log cabins that will become Fort Clatsop. Both men experience the same weather, the same labor, the same roster of injured comrades. Yet their entries differ by an order of magnitude in length and ambition.
Gass writes a single clause:
we continued at our hut-building.
Clark, by contrast, produces two parallel entries — a field note and an expanded version — both of which itemize the sick list and the weather with the precision of a quartermaster’s report.
Gass’s Compression
Gass’s entry is so brief that it barely registers as a sentence. The verb “continued” does almost all the work, signaling that the previous day’s labor is ongoing and that nothing about it has changed enough to warrant comment. The phrase “hut-building” — Gass’s preferred term throughout this stretch — is utilitarian carpentry vocabulary from a man who was, in fact, the expedition’s most experienced carpenter. Where Clark uses the more formal “Cabins for our winter quarters,” Gass uses the workman’s word.
This is characteristic of Gass’s December register. As a sergeant rather than a co-commander, his journal often treats a day’s labor as self-evident and not requiring elaboration. The entry should not be read as indifference; it should be read as a tradesman’s shorthand. The hut is going up. That is the news.
Clark’s Catalogue
Clark, writing in two versions, is doing something entirely different. His field entry and his expanded entry both inventory the same four casualties, with the expanded version naming them:
Sergeant Pryor unwell from a dislocation of his Sholder, Gibson with the disentary, Jo. Fields with biles on his legs, & Werner with a Strained Knee.
The field version is anonymized — “one man with Turners, one with a Strained Knee, one Sick with Disentary” — and only Pryor is named in both. The progression from field to fair copy shows Clark filling in identifying detail as he revises, a habit visible across his Fort Clatsop entries. The captains needed to know who could swing an axe and who could not, and Clark’s bookkeeping reflects that command-level concern.
The weather, too, gets doubled treatment in Clark: “rained all last night moderately” opens the entry, “rained at intervales all day moderately” closes the field note, and the expanded version repeats both observations almost verbatim. This redundancy is not careless — it brackets the working day and confirms that the rain, while constant, was not severe enough to halt construction.
What the Comparison Reveals
Read together, the two narrators show how rank and purpose shape the journal record. Gass writes for a future reading audience that wants to know the expedition’s progress in broad strokes; Clark writes partly for himself, partly for Lewis, and partly for the eventual official account, and he therefore records the granular data — names, ailments, weather intervals — that a leader must track.
The cross-narrator silence is also instructive. Neither man mentions the Clatsop or Chinook neighbors on this day, neither describes the site itself, and neither reflects on the symbolic weight of building permanent shelter at the western terminus of the continental crossing. The entries are operational. The fort is not yet a fort; it is a worksite in the rain, with four men on the sick list and the rest swinging axes.
For researchers, December 11 is a useful baseline date. It demonstrates that the brevity of any single Gass entry should be checked against Clark before being read as evidence of an uneventful day, and that Clark’s medical roster — sometimes the only surviving record of who was injured when — frequently fills gaps the other journals leave open.
