Note 21 — THE EXPLORATION OF THE ROAD

Though the valley is full of clay the road avoids it with remarkable success. Of the eight miles between Alton and Farnham the first three have chosen a narrow strip of good gravel, the next one and a half miles are on green-sand. At the entry to Bentley village the clay is unavoidable, but after a mile of it the road takes advantage of a patch of gravel as far as the Bull Inn. It has then to cross a quarter-mile belt of gault, but beyond this it uses a long, irregular, and narrow patch of gravel, and at the end of this, just east of the county boundary, it finds the narrow belt of sand which it keeps to all the way to Farnham. The whole is an example of how a primitive track will avoid bad soil.
