What the journal records: Pittsburgh to Marietta

Meriwether Lewis pushed off from Pittsburgh at ten in the morning on August 31, 1803, in a 55-foot keelboat built too late in a dry summer, with his Newfoundland dog Seaman aboard. His so-called Eastern Journal — first published in Milo Quaife’s 1916 edition, and transcribed among this site’s journal entries from August 30, 1803 onward — records the miserable first weeks: dragging the boat over riffle after riffle, hiring horses and oxen from riverbank farmers to haul it through, and losing his first experiments to leaky canoes. In the first week of September the party worked past Georgetown and Steubenville, and spent September 7–9 at Wheeling taking on a pirogue and supplies.

The silent stretch: September 19 – November 10

Lewis’s journal breaks off after September 18, 1803, and no daily record by any hand survives for the next seven and a half weeks. The party’s movements are known instead from letters and later documents. They certainly passed the mouth of the Big Sandy — today’s Ashland, Kentucky — and the mouth of the Scioto at Portsmouth, Ohio in the last week of September, because the river was the only road; Lewis was in Cincinnati by September 28, where his October 3 letter to President Jefferson survives, full of the fossil bones he had just examined at Big Bone Lick.

The Falls of the Ohio: the Corps is born

Lewis reached the Falls of the Ohio on October 14, 1803, and there the expedition became a partnership: William Clark came aboard at Clarksville with York, the man he enslaved, and the recruits history remembers as the Nine Young Men from Kentucky — among them Charles Floyd and Nathaniel Pryor. On October 26 the enlarged party pushed off from the Falls into a stretch of river where, once again, no journal survives.

The first camp below the Falls: West Point, Kentucky

Where did the Corps of Discovery spend its first night together on the river? No journal records it. Local and trail-community tradition — consistent with a day’s travel from Clarksville — places that first camp of October 26, 1803 at the mouth of the Salt River, where the town of West Point, Kentucky stands today beneath the bluff later crowned by Civil War–era Fort Duffield. We present it as exactly that: a well-rooted tradition on an undocumented stretch, not a journal fact.

The record resumes: Fort Massac to the Mississippi

Lewis’s journal picks up again on November 11, 1803 at Fort Massac, where the party engaged George Drouillard — the hunter and sign-language interpreter who would become one of its most valuable members. From November 14 the captains spent days at the Ohio–Mississippi confluence taking celestial observations before turning upstream for Camp Dubois. From here forward, the record on this site runs nearly unbroken to St. Louis in 1806.

Sources and method

Documented statements above rest on Lewis’s Eastern Journal (published in Quaife, 1916; public domain), the surviving 1803 journal entries transcribed on this site, and Lewis’s correspondence of the descent. The Salt River first-camp attribution is identified in the text as tradition. Undated passages within September 19 – November 10 are inferred from the geography of the river and the documented endpoints, and are worded accordingly.

The expedition connection is direct. In April 1803, Meriwether Lewis traveled to Ellicott’s home in Lancaster, Pennsylvania, to learn celestial navigation and the practical field surveying he would need in the West, staying about three weeks. Ellicott — himself once a student of Robert Patterson, another of Lewis’s tutors — taught him to fix latitude and longitude with sextant and chronometer. Ellicott’s earlier mapping of the Ohio–Mississippi confluence also informed Nicholas King’s compiled map carried by the Corps of Discovery.

That anxiety is the throughline to Lewis and Clark. The same political drive to bind East and West — pressed by Jefferson’s treasury secretary Albert Gallatin — produced the National Road, which Jefferson signed into law in 1806, extending the improved corridor from Cumberland toward the Ohio River. The roads described here are the eastern arteries along which the expedition’s people, supplies, and correspondence moved.

For Lewis and Clark, the road matters as the realization of the East–West link Jefferson and Albert Gallatin pushed for in the very years of the expedition — and because its precursor, Braddock’s Road, was the route Meriwether Lewis himself took from Harpers Ferry to Pittsburgh in the summer of 1803.

Read alongside four related 1803 letters (including the “Portable Soup” letter to General William Irvine), it reconstructs Lewis’s spring-to-summer travels and introduces the cadre of quartermasters, purveyors, and armory officers — Israel Whelan, Thomas Cushing, Joseph Perkins, George Ingels, and Irvine — who outfitted the expedition. The find reveals Lewis at his logistical best: not only an explorer, but a meticulous quartermaster and project manager.

The Corps did not travel through Shawnee towns on the Missouri. The journals still name the Shawnee twice, and both mentions are worth keeping straight.

On 16 November 1803, after crossing the Mississippi, Meriwether Lewis found Shawnee and Delaware people camped at the upper habitation on the opposite shore:

we found here som[e] Shawnees and Delewars incamped; one of the Shawnees a respectable looking Indian offered me three beverskins for my dog with which he appeared much pleased

That is an Ohio–Mississippi encounter, not a Missouri-river council. Lewis refused the trade. The dog is Seaman.

The second mention is only a comparison. In the long Shoshone ethnography of 19 August 1805 Lewis wrote that Shoshone complexion was “much that of the Siouxs or darker than the Minnetares mandands or Shawnees.” No Shawnee person is on that hillside. The name is a yardstick in Lewis’s head.

A synthesis that claimed the Shawnee were absent from the corpus was describing an empty tag set, not the journals.

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.

In August 1803, while waiting for the keelboat to be completed at Pittsburgh, Meriwether Lewis acquired a large Newfoundland dog for twenty dollars—a substantial sum reflecting both the breed’s reputation and Lewis’s deliberate choice. The dog, named Seaman (long misread in transcriptions as “Scannon”), would become the only animal to travel the full route of the expedition from the Ohio River to the Pacific Ocean and back to St. Louis. Newfoundlands were prized as working dogs: webbed feet, water-resistant double coats, immense strength, and a docile temperament. All of these qualities would be tested over the next three years.

Hunter and Retriever on the Ohio

Within weeks of Seaman’s purchase, Lewis was already recording the dog’s working capabilities. During the descent of the Ohio in September 1803, the party encountered the seasonal mass migration of gray squirrels swimming the river. Lewis described how Seaman seized the opportunity:

My dog was of the newfoundland breed very active strong and docile, he would take the squirels in the water kill them and swimming bring them in the boat.

Lewis noted that the squirrel meat, fried, made “a pleasant food.” From the outset, then, Seaman functioned not as a pet but as a contributing member of the party.

Across the Plains: A Working Dog

References to Seaman accumulate as the expedition pushed up the Missouri. On 25 August 1804, Clark’s overland march to the Spirit Mound included the dog, but the August heat proved too much: “at 7 ms. the dog gave out & we Sent him back to the Creek.” The episode is a small but humanizing detail—even a Newfoundland had limits on the open prairie.

Above Fort Mandan in spring 1805, Seaman wandered off overnight, and Lewis’s journal records genuine alarm followed by relief. On 25 April 1805 Clark wrote that “the Dog which was lost yesterday, joined us this morning,” while Lewis confessed:

my dog had been absent during the last night, and I was fearfull we had lost him altogether, however, much to my satisfaction he joined us at 8 Oclock this morning.

By 5 May 1805 Seaman was again working actively in the food economy of the expedition; throughout the upper Missouri Lewis repeatedly notes him catching geese that, mid-molt, could not fly. On 21 July 1805, ascending toward the Three Forks, Lewis wrote: “my dog caught several today, as he frequently dose.”

The Beaver Bite

Among the dangerous moments of Seaman’s career occurred in May 1805 along the Missouri in present-day Montana, when the dog was bitten by a beaver. The bite severed an artery in his hind leg. Lewis stopped the bleeding with difficulty and wrote, “I fear it will yet prove fatal to him.” Seaman recovered, and the concern in Lewis’s entry reveals the depth of his attachment.

Sentinel at Camp: The Buffalo Stampede

Seaman’s most consequential service may have come on the night of 29 May 1805, when a buffalo bull charged through the sleeping camp, narrowly missing the men’s heads and crashing over the pirogue. Lewis wrote that “my dog saved us by causing him to change his course a second time.” Clark says a man sitting up alarmed the animal. The journals do not say the dog barked the camp awake, or then drove the bull off.

Suffering on the Portage

The summer of 1805 brought torments shared equally by men and dog. During the eighteen-mile portage around the Great Falls, prickly pear thorns drove deep into Seaman’s paws as they did into the men’s moccasins. Then came the mosquitoes. On 15 July 1806 Lewis recorded one of his most poignant lines about the animal:

My dog even howls with the torture he experiences from them.

The remark, set against Lewis’s usual restraint, registers the cumulative misery of the upper Missouri summer.

Pacific Winter and the Whale Blubber Comparison

At Fort Clatsop, Seaman appears less directly in the journals, but the dog—singular, beloved—coexisted there with another reality of the winter: the Corps had become almost wholly dependent on dog flesh purchased from Columbia River nations. Lewis admitted on 3 January 1806:

our party from necessaty having been obliged to subsist some lenth of time on dogs have now become extreemly fond of their flesh … for my own part I have become so perfectly reconciled to the dog that I think it an agreeable food.

Two days later, tasting whale blubber for the first time, he compared it to “the beaver or the dog in flavour.” The juxtaposition is striking: Seaman, the cherished individual, traveled within a culture in which dogs as a class were food. The journals never bridge this contradiction.

The Theft on the Columbia

On the return up the Columbia in April 1806, a group of Native men took Seaman from camp. Lewis’s reaction—recorded by Ordway and reflected in the supplementary expedition tradition—was uncharacteristically violent: he dispatched three armed men with orders to recover the dog or destroy the village. Seaman was returned without bloodshed. Throughout the expedition, several nations had offered horses to purchase him, and Lewis had always refused. The theft incident clarified the limit of his patience.

Hunting Companion to the End

Seaman continued working into the homeward summer. On 8 May 1806 along the Clearwater, Lewis recorded that Collins “wounded another [deer] which my dog caught at a little distance from the camp.” On 23 May 1806 Sergeant Pryor wounded a deer near a lick: “my dog pursud it into the river,” Lewis wrote, and the deer was driven back to shore where Pryor killed it. Crossing the Bitterroots in mid-June, Lewis noted on 7 July 1806—amid the harsh marches and beaver-dam meadows—simply that “my dog much worried.” It is the last clear, intimate glimpse of Seaman in the journals as preserved in this set.

Diplomatic Curiosity

Throughout the journey Seaman drew the attention of Native peoples, many of whom had never seen a dog of his size. The synthesizing entries (18 April 1805) note that Shoshone, Nez Perce, and Plains nations expressed astonishment, and that some offered three horses for him—offers Lewis consistently refused. His presence alongside Sacagawea and her infant also signaled, however unintentionally, that the party was not a war expedition.

The Limits of the Record

The journal record of Seaman is uneven. Lewis is by far the most attentive narrator; Clark mentions the dog only in passing (notably the lost-and-found episode of 25 April 1805 and the deer chase of 23 May 1806). After mid-July 1806 Seaman effectively disappears from the surviving entries in this corpus—his ultimate fate is not documented in the journals included here. What the record does preserve is unmistakable: a working animal who hunted, guarded, suffered, and accompanied Meriwether Lewis from the Ohio to the Pacific and most of the way home, mentioned with an affection Lewis rarely extended in writing to anything else.
