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."
