Along this lane for half a mile through slightly rolling depressions the road runs on to Puzzley Run, and after fording the run passes with a distinct scar north of a vacant log house over a very difficult pass to a lane east of William Augustine's house, and thence along this lane for several rods to the house, which is built on the very roadbed itself and less than one hundred yards from the National turnpike. From Augustine's house the line runs parallel to the turnpike, but a few rods south of it, for over two miles to Coon Spiker's house, showing here and there traces of the road that are more or less distinct. Apparently passing south of this house and on through a lane to the south of Stephen Spiker's house, it presently, a little to the westward, enters a stretch of woods, through which it proceeds over Keyser Ridge, where, although there is a very luxuriant growth of underbrush, the trace of the road for a little over two miles is so distinct as to leave no doubt in regard to its course over this rocky and very difficult pass. From the woods it emerges into the bottom of the north fork of Mill Run, less than half a mile from the Pennsylvania and Maryland boundary line at Oakton, Maryland.[46] Here, in one of the most picturesque places for an encampment along the entire route, was Bear Camp.[47] Leaving Bear Camp, the road, after crossing Mill Run, intercepts the Pennsylvania boundary line, and a few rods farther on crosses the National turnpike less than one-fourth of a mile west of Oakton. It then continues its course over Winding Ridge, on which the traces of it are especially well marked. On the west side of this ridge the line passes north of an old milk house and of a stone house owned by William Miller. About half a mile westward it joins the National turnpike, which it follows for nearly six hundred feet, and then veers away in a northerly direction through some woods, crossing the headwaters of Laurel Run near an old chestnut tree, two hundred yards east of Edward J. Augustine's house. From this point to Addison, a little over a mile distant, the road parallels the turnpike less than quarter of a mile to the north of it.
