Voice
Patrick Gass writes like a man balancing a ledger at the end of a long day. His entries are short, declarative, and structured around a small set of recurring categories: distance traveled, side of the river encamped on, weather, game procured, and notable terrain. The opening of nearly every voyage entry follows a near-identical formula — proceeded on, passed a creek, killed a deer, encamped on the south side. On 1804-07-10 the entire entry reads:
“fair day and fair wind. There is a handsome prairie on the south side opposite an island. We encamped on the north side.”
This is the Gass register at its purest: the prose of a non-commissioned officer trained to render the day legible at a glance.
Yet Gass is not without literary touches. He occasionally reaches for the picturesque (“a beautiful country and the land excellent,” 1804-06-09) and is willing to risk a wry editorial flourish. Describing Chinookan women’s bark fringe skirts on 1805-11-17, he writes:
“These tassels or fringe are of some use as a covering, while the ladies are standing erect and the weather calm; but in any other position, or when the wind blows, their charms have but a precarious defence.”
This is one of the few moments when Gass the man steps out from behind Gass the recorder — and it is characteristic that the joke is dry, observational, and structural rather than sentimental.
Omissions
What Gass leaves out is as telling as what he includes. He rarely names individual men. Captain Lewis and Captain Clarke appear constantly; “one of the hunters,” “one of the men,” “three of the party” do almost all the rest of the work. Sacagawea is referenced obliquely (“our interpreter’s child has been very sick,” 1806-05-25); York is essentially invisible; Charbonneau scarcely registers as an individual.
Emotional life is also largely absent. Gass mentions fear or hardship only when they affect the work: men “poor and uncomfortable enough” with nothing to eat in the Bitterroots (1805-09-02), the boat “in great danger” on 1804-06-09, the Experiment boat being finished and christened (1805-07-08). Where Lewis would philosophize and Clark would plot, Gass simply notes outcomes. The Shoshone reunion of Sacagawea and Cameahwait — high drama in other journals — passes through the Gass record (1805-08-24) almost entirely as a logistical problem about whether the river is passable.
Theological and patriotic reflection is nearly nonexistent. There are no apostrophes to Providence, no meditations on empire. The continent in Gass’s pages is a series of bottoms, bluffs, and creeks to be measured, not a destiny to be claimed.
Patterns
Several recurring preoccupations distinguish Gass from his fellow journalists.
Construction and craft. Gass was the expedition’s chief carpenter, and his journal lights up whenever building is involved. His description of the Arikara earth lodges on 1804-10-10 is essentially a builder’s specification, written with a tradesman’s eye for sequence:
“In a circle of a size suited to the dimensions of the intended lodge, they set up 16 forked posts five or six feet high, and lay poles from one fork to another. Against these poles they lean other poles, slanting from the ground…”
The same eye appears at Fort Clatsop on 1805-12-14, where he notes the discovery of split-cedar puncheons “10 feet long and 2 broad, not more than an inch and an half thick” with the satisfaction of a man who has just found good lumber.
Measurement. Gass is obsessed with dimensions. The brown bear killed on 1805-05-05 is rendered almost entirely as a tape-measure exercise:
“three feet five inches round the head; three feet eleven inches round the neck; round the breast five feet 10 1-2 inches; the length eight feet 7 1-2 inches; round the middle of the fore leg 23 inches; and his talons four inches and three eights of an inch.”
The Celilo falls (1805-12-23) get the same treatment: “The whole height of the falls is 37 feet 8 inches, in a distance of 1200 yards.” Gass quantifies the world.
Game accounting. Almost every entry tallies what was killed. The journal functions as a continuous quartermaster’s report on calories. When game is scarce, he says so flatly (“a small quantity of dried salmon… is almost our whole stock of provisions,” 1805-09-02); when it is abundant, he counts (“in a short time killed five buffaloe,” 1806-07-11; “killed fifteen of them,” 1806-07-31).
Side of the river. No journalist is more faithful to the cardinal-direction encampment note. “Encamped on the north side,” “encamped on the south side” close hundreds of his entries. For Gass, the day is not over until the camp’s bank is recorded.
Comparisons and Change Across the Journey
Gass’s prose evolves subtly. The early Missouri entries (1803-10-31 through summer 1804) are the most formulaic — a metronome of creeks, prairies, and deer. Once the expedition reaches the Mandan winter of 1804–05, his entries lengthen as he is given a stationary subject: hunting parties, building Fort Mandan, the theft of horses (1805-02-20), the construction of the canoes (1805-03-01). Stationary work suits the carpenter.
Crossing the Bitterroots in September 1805 produces some of his most vivid writing — vivid by Gass standards, which is to say, the formula bends under stress. On 1805-09-02 he abandons his usual brevity:
“the worst road (if road it can be called) that was ever travelled… in some places we were obliged to go up the sides of the hills, which are very steep, and then down again in order to get along at all. In going up these ascents the horses would sometimes fall backwards, which injured them very much.”
The parenthetical (“if road it can be called”) is the closest Gass comes to a cry of complaint.
At Fort Clatsop, the journal contracts again. Rain dominates: “There is more wet weather on this coast, than I ever knew in any other place; during a month we have had but 3 fair days” (1805-12-05). Winter at Clatsop is a litany of skin-dressing, salt-making, and elk-hunting parties — the carpenter without timber to work, falling back on inventory.
On the return journey, Gass loosens slightly. He records ethnographic details with more confidence (the Walla Walla returning a steel trap, 1806-05-02, prompts him to call it “perhaps one of the greatest instances of honesty ever known among Indians” — a rare evaluative judgment). He notices birds and squirrels with something like curiosity (1806-06-12), describing a new woodpecker by feather-tip color. The traveler has begun, however cautiously, to look up from the ledger.
Compared to Lewis’s literary aspirations, Clark’s commanding navigational prose, Ordway’s steady middle register, and Whitehouse’s awkward earnestness, Gass occupies a distinctive place: he is the working sergeant whose journal could double as a daybook for a construction crew. His was the first of the expedition journals to be published (1807, in a heavily edited David McKeehan version), and one suspects part of its early appeal was precisely this clarity — a continent rendered in the plain syntax of mileage, weather, and game, by a man who measured a bear’s talon to the eighth of an inch and noted, every night, which bank he slept on.
