I went straight on across the byway, the path continuing through High Scrubs for almost another half a mile to reach another lane. Across this a path continued just inside the right edge of Wick Wood, following the line of an ancient earthwork called Grim's Ditch. On leaving this attractive Beech wood, the path continued to follow the line of the earthwork for about another half mile, running more or less dead straight. Just after passing a line of gorse bushes, the path reached a hedgerow and turned right. Within a few yards I reached a path junction where I turned half-right (the other path went left, to reach a road on the edge of Wigginton).

The path crossed part of a large arable field, went through a small corner of a meadow, then continued in the same southerly direction across a very large meadow, aiming for a far corner where it entered Roundhill Wood. I went more or less straight on here, following the path through the wood, to reach a road running along the far side. I crossed the road and followed a bridleway along a farm track that after about half a mile reached Tring Grange Farm.
