He will see from the heights even to-day the remains of the woodland which made the valleys and the wealds originally far more difficult to traverse. He will note the greater dryness of these heights, and he will remark, if he contrast his cross-country going on the hills with that of the valleys, that the geological formation of these heights, with their contours, fit them peculiarly for an original means of communication. Four out of the five are great dry, turf-covered ridges of chalk, steep towards the summer sun. The fifth range, the Cotswold, though oolitic and therefore greasy under foot, is at the summit of its western escarpment much drier than the valleys; for that escarpment is steep, and drains off well into the valley of the Severn. When one has once recognised the importance of these five radiating lines of hills and of their point of convergence, one will next see that of the five, one in particular must have had an especial value perhaps in the very earliest times, and certainly in all the centuries just preceding the historic period, during which Britain, from similarities in religion, language, and blood, was closely connected with the Continent. The passage westward from the Straits of Dover to the Hampshire centres must have been by far the most important line of traffic. We know that it has been so continuously in historic times, and it is easy to prove that long before the opening of our national history with the Roman invasions, some east-to-west road must have been the leading road of England. Few of the following considerations are new, but all are to the purpose: 1. The Straits of Dover are the natural entry into the country. The nature of that entry, and its very great effect upon the development of our island, I will discuss later in connection with the town of Canterbury. How far the Straits may have a rival lower down the Channel I will discuss in connection with the town of Winchester. For the present, the main point is that in the earliest times, whoever came in and out of the country came in and out most easily by the only harbours whence the further shore is visible. 2. When the Straits had been crossed and England entered, whither would the principal road lead? The conformation of Kent forced it westward, for the Thames estuary forbade a northern, the only alternative route. One track of great importance did indeed go north and west, crossing near London. It was later known as the Watling Street; it was the artery which drained the Midlands; it became the connection with sacred Anglesey, ultimately the northern door into Ireland.
