Historic Highways of America/Volume 6/Chapter 2

CHAPTER II

THE FIRST EXPLORERS

THE first real explorations of the great territory secured by Virginia at the Treaty of Fort Stanwix were made by Dr. Thomas Walker, who later so skilfully managed Virginia's part of that treaty, and Christopher Gist, in the early years of the second half of the eighteenth century, 1750 and 1751.

The brief journals[1] written by these men are the sources of our first information concerning the vast territory west of the Appalachian mountain system—the eastern half of the Mississippi basin south of the Ohio River. They are meager records of hard day's pilgrimages, an outline of the routes pursued, and a description of the lands which were traversed. Both were explorers for two newly-formed land companies. Walker represented the Loyal Land Company of London, and Gist was the representative of the Ohio Company. The company for which Walker acted had secured a grant of eight hundred thousand acres in the territory now embraced in Kentucky north of 36° 30′. The Ohio Company had a grant of five hundred thousand acres between the Kanawha and Monongahela Rivers. These men were sent to search out favorable lands and report on the giants and grapes. They found both.

Little suggestion of the romance and daring of these historic journeys can be found in either of the journals of them; they make slight books. But volumes can be written on what can be read by the most careless reader between their few lines. The long climbing over the almost pathless mountains, the nights spent in discomfort, the countless trials, fears, dangers of which they knew so much and told so little—all this should make a story if it never has, that could not by any means find an uninterested reader. No youth's history is of moment until we know the man and know that he is a man among men. Our nation is still a boy. Only with the passing of the years will its boyhood be studied and known as it should be known; when that time comes, the brief stories of such men as Walker and Gist will appear of priceless value.

"Having, on the 12th of December last, been employed for a certain consideration to go to the Westward in order to discover a proper Place for a Settlement, I left my house on the Sixth day of March, at 10 o'clock, 1749–50, in Company with Ambrose Powell, William Tomlinson, Colby Chew, Henry Lawless & John Hughs. Each man had a Horse and we had two to carry the Baggage. I lodged this night at Col. Joshua Fry's, in Albemarle, which County includes the Chief of the head Branches of James River on the East side of the Blue Ridge." Thus begins Dr. Walker's journal. At this time England and her colonies were dating by the old calendar, each new year beginning on the twenty-fifth of March. Accordingly they started nineteen days before the beginning of the year 1750.

It was a brave little company of adventurous men. Walker had attended William and Mary College, and then had joined the ranks of that distinguished army of representative Virginians who, with saddle-bags and surveying instruments, proved to be the vanguard of the army which was to achieve the real conquest of the West. His home was Castle Hill, near Charlottesville, Albemarle County, Virginia, where his companions had rendezvoused for the present expedition and from which point they began their historic journey. Powell was of the best Virginian stock, and has left his name to one of the great valleys through which the highway to the West ran. His son became a Revolutionary officer and his great-grandson was General A. P. Hill, the famous Confederate leader. Chew was from Orange County, Virginia, and belonged to the Maryland branch of the Chew family. Two Presidents of the United States, Madison and Taylor, could claim him as a relative. Seven years later he served in Washington's regiment in Forbes's expedition against Fort Duquesne, and was killed in Grant's wild attack on that fort. As the journal states, this company spent the first night out with Colonel Joshua Fry. Fry too was one of them in spirit, though he did not accompany them westward. He was a graduate of Oxford University, joint author with Jefferson of Fry and Jefferson's celebrated Map of Virginia, and a commissioner for the crown in establishing the boundary line between North Carolina and Virginia. He was killed by being thrown from his horse while taking command of Washington's expedition against Fort Duquesne, four years later. These statistics show plainly that the best brain and blood of Virginia was foremost in attempting to realize Virginia's dream of conquest and expansion.

But it was a time for brave men to show themselves. Ambitious Virginia had been slow to claim the West, where even at this early date Frenchmen had gone so far into the wilderness. Céloron, bold emissary of the humpbacked Canadian Governor Gallissonière, was now burying leaden plates at the mouths of the rivers which emptied into the Ohio, as a sign of French possession of the West. One of these was placed at the mouth of the Great Kanawha "at the mouth of the river Chinodahihetha, this 18th day of August," claiming for the Bourbon crown the entire territory in which the grant of land to the Ohio Company was located. There was not a moment to lose if the West was to be saved to England. A settlement must be made quickly, and Walker and his band pushed on immediately to find a "proper Place for a Settlement."

But all this, seemingly, is neither here nor there—so far as Walker's Journal is concerned. There is not one mention of the political crisis then at hand; instead of French claims, Walker deals with tired horses or broken-legged dogs, and where one might suppose he would mention national boundary lines he tells only of cutting names on trees. And at the end, where the reader might look for a summary statement of the results of his tour he finds this: "I got home about noon. We killed in the Journey 13 Buffaloes, 8 Elks, 53 Bears, 20 Deer, 4 Wild Geese, about 150 Turkeys, besides small game. We might have killed three times as much meat, if we had wanted it." Yet, so far as human interest is concerned, the record is exceptionally entertaining, and to a student of the great thoroughfare from Virginia to Kentucky it is full of meaning; because of its many references to the difficulties of traveling at that early date, and to the varied experiences of explorers on the earliest thoroughfares westward. It is this story of experience in traveling west in 1750 that makes Walker's Journal of interest in the present study.

On the day after the party left Colonel Fry's, "We set off about 8," writes Dr. Walker, "but the day proving wet, we only went to Thomas Joplin's on Rockfish. This is a pretty River, which might at a small expense be made fit for transporting Tobacco; but it has lately been stopped by a Mill Dam near the Mouth to the prejudice of the upper inhabitants who would at their own expense clear and make it navigable, were they permitted." Virginia's great industry evidently flourished this far from tidewater even at this early date, though handicapped by these dams which were erected by the "Averice of Millers," on which Dr. Walker comments again in his next day's record. The record for Sunday, the eleventh, is appropriately brief: "11th. The Sabbath." In only one or two instances did the party travel on Sunday, and then the journey was occasioned by necessity. On the twelfth the party crossed the Upper James River above the mouth of the Rivanna, and lodged with one Thomas Hunt.

"13th. We went early to William Calloway's and supplied ourselves with Rum, Thread, and other necessaries & from thence took the main Waggon Road leading to Wood's or the New River. It is not well clear'd or beaten yet, but will be a very good one with proper management." Wood's River—or New River, as we know it today—was discovered in 1671 by Colonel Abraham Wood, who explored along the line which later became the boundary line between North Carolina and Virginia. He crossed the Alleghenies through "Wood's Gap" (now Flower Gap) and, going down Little River, found New River not far from Inglis Ferry, where Walker's party crossed three days later. This mention of the road Walker traversed is his first reference to the great road westward toward Cumberland Gap; he remarks its roughness, but before he returned to Virginia he learned new lessons on rough roads. "This night we lodged in Adam Beards low grounds. Beard is an ignorant, impudent, brutish fellow, and would have taken us up, had it not been for a reason, easily suggested." When thus brought in contrast with the hospitality usually tendered Walker's party, the deportment of this churlish mountaineer is conspicuous. Travelers on these first highways were ever in need—if for nothing more than a camping-place. The people who settled beside the frontier roads were trained by bitter experience to a generous hospitality. This hospitality was particularly marked, throughout the colonies, among those who could afford it, especially on the frontiers; and here it was often bestowed upon travelers when it could be ill-afforded. The modern hotel has in a large measure relieved the general public from the burden of continual and promiscuous hospitality, and it has been found that where hotels are least known this prime requisite of an expanding civilization may still be found. On the frontier, men were dependent on those who lived beside the road, not only in time of accident and sickness, but at all times—for little food and forage could be carried. At times travelers nearly perished when once beyond the frontier line. Walker's party, though they killed the large amount of game mentioned, were once compelled to kill and eat one of their dogs. Captain Estill, who lost his life in Kentucky in the engagement which bears his name, is said to have done a great service for emigrants from Virginia by killing game and leaving the meat beside the road, in order to "pass on and notify incoming trains where they might find a supply of meat."

Instances of vile treatment of travelers are not often cited, but the few that exist are the exceptions that prove the rule of generosity which was common to the time.

Leaving Beard's, Walker and his men went, on the fourteenth, to Nicholas Welch's, "where," the Doctor writes, "we bought corn for our horses, and had some Victuals dress'd for Breakfast." From here they climbed the Blue Ridge through Buford's Gap, in Bedford County, through which the Norfolk and Western Railroad now passes. "The Ascent and Descent is so easie," writes Walker, "that a Stranger would not know when he crossed the Ridge." On the day after, they reached "the great Lick" near the present city of Roanoke, and continued up the trail on the following day to near the historic Inglis Ferry, not far from the present village of Blacksburg, Montgomery County, Virginia.

From this on, Walker's route is not of importance to our study, as he missed the great trail which would have taken him to the pleasant meadows of Kentucky—though he struck it again at Cumberland Gap but did not follow it—and wandered over a circuitous route thus outlined by Daniel Bryan: "They started from low down in Virginia, traveled westwardly across Alleghany Mountains to Chissel's Lead Mine, on New River; thence into the Holston Valley, thence over Walden's Ridge and Powell's Mountain into Powell's Valley. . . They then continued down the valley, leaving Cumberland Mountain a small distance on their right hand, until they came to Cumberland Gap. . . At the foot of this mountain they fell into an Indian path leading from the Cherokee towns on Tennessee River to the Shawnee Indian towns on the Ohio, which path they followed down Yellow Creek to the old ford of Cumberland River. . . Thence they went on the path down the river to the Flat Lick, eight miles; here they left the river, continued on the path, turning more north, crossing some of the head branches of the Kentucky River over a poor and hilly country, until they concluded there was no good country in the West. They then took an easterly course over the worst mountains and laurel thickets in the world. . . They crossed the Laurel or Cumberland Mountain and fell into the Greenbrier country, almost starved to death . . and reached home with life only to pay for all their trouble and suffering."

Regretting that this opinion of the final value of Walker's journey cannot be gainsaid, it is yet of interest to follow his footsteps and learn what were some of the experiences of such early explorers as these.

On the twenty-sixth they "left the Inhabitans," as Dr. Walker called the line of civilization, and were at last within the wild land where no settlers had yet come. On the night of the twenty-ninth the "Dogs were very uneasie," and the next day, on Reedy Creek, a branch of the South Fork of the Holston, the tracks of a party of Indians were discovered, which explained the restlessness of the dogs. It is probably little realized in this day how valuable dogs were to explorers and immigrants. They were not only of service in giving warning of the approach of strangers, but were well-nigh indispensable in securing game and in searching for lost horses. Dr. Walker's love for dogs is a tradition in the family, and his care of them on this journey is typical of the gentleman and the wise frontiersman. At the junction of Reedy Creek and the Holston—an historic spot in Tennessee—Walker found a gigantic elm tree, which measured twenty-five feet in circumference at a distance of three feet from the ground. Pioneers and explorers considered the study of trees a fine art. By this means they always judged the quality of the soil, and knew at a glance by the growth that stood on it the character of any piece of land. The diaries of all that old school of western adventurers contain frequent mention of trees which were an almost infallible criterion of the soil beneath. Washington had keen eyes for trees—as for everything else—as illustrated in the journal of his trip down the Ohio River in 1770. On the fourth of November he found a sycamore on the Great Kanawha, in comparison with which this first elm of Walker's was insignificant. It measured, three feet from the ground, forty-five feet in circumference, and near by stood another measuring thirty-one feet around. Upon hearing about this larger tree, some one remarked that Washington might have told the truth about the cherry tree but he told a "whopper" about the sycamore. But it was not guess-work, for the record states clearly that the girth of the larger tree lacked two inches of being the complete forty-five feet. Trees along the Ohio grew to an immense size; an old Ohio River pilot affirms that in his boyhood a burned trunk of a sycamore stood on his father's farm on the Little Muskingum, into which he has frequently driven a horse, turned it about, and come out again. General Harmar found on the Ohio a buttonwood tree forty-two feet in circumference, which held forty men within its trunk.

On the seventh of April Dr. Walker writes: "It snowed most of the day. In the Evening our dogs caught a large He Bear, which before we could come up to shoot him had wounded a dog of mine, so that he could not Travel, and we carried him on Horseback, till he recovered." On the thirteenth the party reached "Cave Gap," which Walker named Cumberland Gap in honor of the "bloody Duke," the hero of Culloden. "Just at the foot of the Hill is a Laurel Thicket. . . On the South side is a plain Indian Road. on the top of the Ridge are Laurel Trees marked with crosses, others Blazed and several Figures on them. . . This Gap may be seen at a considerable distance, and there is no other, that I know of, except one about two miles to the North of it, which does not appear to be So low as the other. The Mountain on the North Side of the Gap is very Steep and Rocky, but on the South side it is not So. We called it Steep Ridge."

The party crossed the Cumberland River about four miles below the present village of Barbourville, Knox County, Kentucky, on the twenty-third of April. The river was named by Walker at this time. From this spot Walker, with two companions chosen by lot—Powell and Chew—went on a tour of exploration alone, leaving the others "to provide and salt some Bear, build an house, and plant some Peach Stones and Corn."

Walker and his two companions floundered about the neighboring region for five days, not getting out of the mountainous country and not finding any good land. They crossed the Cumberland again, on the third day out, about twenty miles below the first crossing-place, and then returned up the river to the main party and found that the work he had ordered to be done was completed. "The People I had left had built an House 12 by 8, clear'd and broke up some ground, & planted Corn, and Peach Stones."

Thus was raised, beside the tumbling Cumberland, on the farm now owned by George M. Faulkner four miles below Barbourville, Kentucky, the first house now recorded as built by white men in the fine territory between the Cumberland Mountains and the Ohio River, now the state of Kentucky. It was not an "improver's cabin"—a log pen without roof—but a roofed house, and instituted what the English Loyal Land Company could claim to be a "settlement" in the territory which they had been granted. This was completed by the planting of corn and peach trees. The formality of this "settlement" is evinced by the fact that, two days later, the entire party moved on for further exploration, never again to return to their house or to reap their crops. It was twenty years before a house was erected in Kentucky for the permanent dwelling.

From this on, Dr. Walker's journal is a long story of accidents and disappointments. One horse became lame, and "another had been bit in the Nose by a Snake." "I rub'd the wounds with Bear's oil, and gave him a drench of the same and another of the decoction of Rattle Snake root some time after." On the same day "Colby Chew and his Horse fell down the Bank. I Bled and gave him Volatile drops, & he soon recovered." On the first of May they reached Powell's River. This was named from Ambrose Powell. During the journey Dr. Walker gave the name of each of his companions to rivers he discovered; none were given his name, though a mountain range to the north of Fort Chiswell still bears the name of Walker's Mountain. On Powell's River the party this day again struck the Indian path which later became the great highway to Kentucky. Again he was on the route that would have taken him to the famous meadows below the foothills of the mountains, and again he left it as he did when he chose to explore on the south side of Cumberland Mountain, instead of crossing at Pineville and following the trail northward. He did not cross Rockcastle River. J. Stoddard Johnson says: "This was the farthest western point reached by Doctor Walker. He did not cross the main Rockcastle River, and, therefore, was never on the waters of Salt or Green rivers, as claimed by some. A day or two's travel to the west or northwest would have brought him to the fertile lands of Lincoln or Madison County, his description of which would have left no doubt of his having passed the watershed between the Rockcastle, the Salt, and the rivers to the westward."[2]

Shoes formed an important item in the catalogue of necessaries for the early traveler's outfit on the first traveled ways in America. Already Walker's party, though they traveled largely by horse, had worn out the shoes with which they started, and on the eleventh of May under one of the great cliffs near Rockcastle River they set to work to make themselves new shoes out of elkskin. "When our Elk's Skin was prepared," writes Dr. Walker on the fourteenth, "we had lost every Awl that we brought out, and I made one with the Shank of an old Fishing hook, the other People made two of Horse Shoe Nails, and with these we made our Shoes and Moccosons."

On the twenty-third the party was on the Kentucky River, where Walker found a sycamore which measured forty feet in circumference—almost, it will be seen, the size of the tree Washington found on the Great Kanawha—upon which he marked his initials, "T. W." On the day after, he found another sycamore thirty feet in circumference. These trees, it would naturally be inferred, marked the location of fertile soil. On the twenty-sixth the "Dogs roused a large Buck Elk, which we followed down to a Creek. He killed Ambrose Powell's Dog in the Chase, and we named the Run Tumbler's Creek, the Dog being of that Name."

"31st. We crossed 2 Mountains and camped just by a Wolf's Den. They were very impudent and after they had twice been shot at, they kept howling about the Camp. It rained till Noon this day."

"June ye 1st. We found the Wolf's Den and caught 4 of the young ones." It was very common for frontiersmen to invade the dens of wolves without any opposition on the part of the old wolves. Wolf cubs have often been pulled away from their mothers, who would only snarl and show their teeth. Bears, on the other hand, would fight to the death any invader of their dens. Notions which commonly prevail today, about the dangers in the primeval forests of America from wild animals, undergo a great change after a careful reading of pioneer literature.

On the fourth of June "a very black Cloud appearing, we turn'd out our Horses, got tent Poles up, and were just stretching a Tent, when it began to rain and hail, and was succeeded by a violent Wind which Blew down our Tent & a great many Trees about it, several large ones within 30 yds. of the Tent. We all left the place in confusion and ran different ways for shelter. After the Storm was over, we met at the Tent, and found all safe."

On the fourteenth the party had gone east as far as the dividing ridge between the two forks of the Big Sandy; but within a few days the horses were spent, and the whole party floundered onward afoot. On the twentieth they reached Flat-top Mountain, Raleigh County, West Virginia. This day Dr. Walker's horse was bitten by a snake; " . . having no Bear's Oil," he wrote, "I rub'd the place with a piece of fat meat, which had the desired effect."

Passing the present site of Hinton, West Virginia, the party followed about the present line of the Chesapeake and Ohio Railway. They crossed the Allegheny divide July 8, and Hot Springs the ninth. They found "Six Invalides there. The Spring Water is very Clear & warmer than new Milk, and there is a spring of cold Water within 20 feet of the Warm one. I left one of my Company this day." They reached Augusta Court House (Staunton, Virginia) on the eleventh, and Castle Hill on the sixteenth, having been four months and seven days on the journey.

Walker's hard tour amounted to very little for the plain reason that he never got west of the mountains. He found no good land and his report was depressing.


It remained for another brave frontiersman to go further and bring back the welcome news of large areas of splendid land in the Ohio Valley. In 1748 John Hanbury, London merchant; Thomas Lee, President of the Council of Virginia; and a number of prominent Virginians formed the Ohio Company, elsewhere mentioned, and received a large grant of land in the West. The grant was made March 18, 1749: two hundred thousand acres between the Monongahela and Great Kanawha Rivers, and later three hundred thousand acres, to be located on the waters of the lower Ohio. In 1750 this company employed Christopher Gist, a hardy, well-trained frontiersman who lived on the Yadkin in North Carolina, to explore the Ohio Valley and make a report upon the land there found. For his arduous service he was to receive one hundred and fifty pounds sterling "and such further handsome allowance as his service should deserve." His instructions read as follows:

"You are to go out as soon as possible to the Westward of the great Mountains, and carry with you such a Number of Men as You think necessary, in Order to Search out and discover the Lands upon the river Ohio & other adjoining Branches of the Mississippi down as low as the great Falls thereof: You are particularly to observe the Ways & Passes thro all the Mountains you cross, & take an exact Account of the Soil, Quality & Product of the Land, and the Wideness and Deepness of the Rivers, & the several Falls belonging to them, together with the Courses & Bearings of the Rivers & Mountains as near as you conveniently can: You are also to observe what Nations of Indians inhabit there, their Strength and Numbers, who they trade with, & in what Comodities they deal.

"When you find a large quantity of good, level Land, such as you think will suit the Company, You are to measure the Breadth of it, in three or four different Places, & take the Courses of the River & Mountains on which it binds in Order to judge the Quantity: You are to fix the Beginning & Bounds in such a Manner that they may be easily found again by your Description; the nearer in the Land lies the better, provided it be good & level, but we had rather go quite down the Mississippi than take mean broken Land. After finding a large Body of good level Land, you are not to stop but proceed further, as low as the Falls of the Ohio, that we may be informed of that Navigation; And You are to take an exact Account of all the large Bodies of good level Land, in the same Manner as above directed that the Company may the better judge when it will be most convenient for them to take their Land.

"You are to note all the Bodies of good Land as you go along, tho there is not a sufficient Quantity for the Company's Grant, but You need not be so particular in the Mensuration of that, as in the larger Bodies of Land.

"You are to draw as good a plan as you can of the Country You pass thro: You are to take an exact and particular Journal of all Your Proceedings, and make a true Report thereof to the Ohio Company."

Gist was the man for the business in hand. He came from an enterprising family and was well educated. His father was one of the Commissioners for laying off the city of Baltimore. "Little is known of his early life, but the evidences he has left in his journals, his maps, plats of surveys, and correspondence indicate that he enjoyed the advantages of an education superior to that of many of his calling in those early days. His signature and manuscript are characterized by the neatness and uniformity of a copy plate, while his plats and surveys are models in their mathematical exactness and precision of drawing. To this evidence of scholarly order and professional skill he added the hardy qualities of the pioneer and backwoodsman, capable of enduring the exposure of long journeys in the most rigorous weather. In him were combined the varied talents which made him at once an accomplished surveyor, an energetic farmer who felled the forest and tilled the soil, a skilful diplomat who understood the Indian character and was influential in making treaties, a brave soldier, an upright man, trusted by the highest civil and military authorities with implicit faith."[3]

The earlier portion of Gist's journey, which he began in October, 1750, is not of importance in the present monograph. He reached the Ohio River by way of the Juniata and Kiskiminitas Rivers. Crossing the Ohio he worked his way westward on the Great Trail to the "Crossing Place of the Muskingum" (Bolivar, Ohio), and from thence he traversed the Indian trail to the country of the Shawanese and Miamis.

It was not until Tuesday, the twelfth of March, that Gist again crossed the Ohio, and entered what is now the state of Kentucky. His first day's experience was typical—in a land so well known for great things and strong; for on the day after crossing at the Shawanese Shannoah Town, he found two men who had "Two of the Teeth of a large Beast. . . The Rib Bones of the largest of these Beasts were eleven Feet long, and the Skull Bone six Feet wide, across the Forehead, & the other Bones in Proportion; and that there were several Teeth there, some of which he called Horns, and said they were upwards of five Feet long, and as much as a Man could well carry."

Gist was now in Kentucky—the land of which thousands were waiting to hear, the home of the race that was to come and conquer and settle and hold the West. Of it Gist came to know only a little, but this little was the beginning of a revelation.

After crossing the Ohio, Gist journeyed over a hundred miles down the southern bank of the river, and on March eighteenth crossed "the lower Salt Lick Creek," the Licking River. Reports of Indians at the "Falls" and "the footsteps of some Indians plain on the Ground" made him desist from visiting that spot, but he took down descriptions of it. On the nineteenth he turned southward into the interior. On the twentieth he ascended Pilot Knob, near Clay City, Powell County, and writes of the view from that height from which he saw, as John Finley wrote later, "with pleasure the beautiful level of Kentucky."

With but a glimpse of the good lands of Kentucky, Gist, like Walker before him, journeyed into the mountainous country to the southeast. For a month he floundered around in the desolate laurel ridges where Walker had spent so many distressing days the year before. On Red River Gist crossed Walker's route and came on homeward between Walker's outward and homeward courses. From Red River he went through Pound Gap and eastward, down what is known as Gist's or Guesse's Fork of the Clinch in Wise County, Virginia, and then upon Bluestone, a tributary of New River. On the thirteenth of May he crossed Walker's route again at Inglis Ferry, near Draper's Meadows. On the seventeenth he passed into North Carolina through Flower or Wood's Gap toward his home on the Yadkin. He reached home on the eighteenth and found that his family had removed to Roanoke, thirty-five miles eastward, because of depredations of the Indians during the winter.

Gist's journey was far more successful than Walker's. He found the fine fertile valleys of the Muskingum, Scioto, and Miami Rivers north of the Ohio, and he caught a glimpse of the beautiful meadows of Kentucky. He singularly made a complete circle about the land between the Monongahela and Kanawha Rivers, where the Ohio Company's grant of land was made. As he did not approach it on any side it is probable that he knew that only rough land lay there. Had it not been for the sudden breaking out of the old French War, the Ohio Company would undoubtedly have settled on lands in the Ohio Valley according to Gist's advice. Hostilities on the frontier soon drove back the farther settlements, and rendered activities in the land Gist had discovered out of the question, either on the part of land companies or private individuals.
