Chalk is viscous and spongy when it is wet. It is never so marshy as to lose all impression made upon it. It is never so hard as to resist the wearing down of feet and of vehicles. Moreover, those who are acquainted with chalk countries must have noticed how a road is not only naturally cut into the soil by usage, but forms of itself a kind of embankment upon a hillside from the plastic nature of the soil. The platform of the road is pressed outward, and kneaded, so to speak, into an outer escarpment, which would make such a track, for generations after it was abandoned, quite plain along the hillside. Finally, there are, or were until lately, no forces at work to destroy such a record. The chalk was little built upon; it had no occasion to be largely traversed by modern roads; it stood up in steep hills whereon no one would have dreamt of building, until the torture of our modern cities drove men to contrast. How these hills invited, and almost compelled, the primitive traveller to use them has been already described. Once he began to use their soil, better than any other soil in England, it would retain his memory. * * * * * Now since some considerable portion of the Old Road has been preserved, a basis for knowledge is afforded. Patches aggregating in length to just over eighty miles are certain and fixed. It is possible to work from that known thing to the unknown, and the gaps where the Road is lost can be recovered by the consistent pursuit of a certain method; this method when it is described will be seen to lend to a first vague and tentative examination a greater value than it seemed to promise. It permitted us to establish by converging lines of proof so much of what had been lost, that one may now fairly call the full course of the Road established from the north gate of Winchester, whence it originates, to the west gate of Canterbury, which is its goal. A description of our method is a necessary preliminary to that of the journey upon which it was put to the test. The reconstitution of such a road is essentially the filling up of gaps. The task would be impossible if a very large proportion did not remain evident to the eye, or recorded by continuous history. The task would be much more difficult if the gaps in question were of very great length, succeeded by equally long unbroken pieces of the existing road. Luckily, the record or preservation of the Pilgrim's Way has not fallen upon these lines. There is no continuous gap throughout the whole of these 120 miles of greater length than seven miles, and we have in what may be called the 'known portions,' stretches of ten, thirteen, and even fifteen miles, almost unbroken.
