There is a deep combe at Holybourne Down, two more on either side of Froyle, a fourth beyond Bentley, a fifth—smaller—before Farnham. All these gullies cut up into a hopeless tangle what in Surrey and Kent will become one unbroken bank of chalk. Any path attempting these hillsides would either have doubled its length in avoiding the hollows, or would—had it remained direct—have been a succession of steep ascents and falls; all the dry slopes which bound the vale to the north are a succession of steep and isolated projections, thrust out from the distant main chain of the chalk; many of them are crowned with separated summits. The road is therefore compelled to follow the valley floor with all the consequences I have noted. As far as Froyle, two and a half miles from Alton, it never leaves the river by more than a quarter of a mile, but the valley is here dry, the soil gravelly and sandy, the height considerable (above three hundred feet), and there is no reason why it should go further from the stream than it did in the valley of the Itchen.
