SUSSEX HILLS
THE CHALK-RANGES
The principal hill ranges of South England, the Chilterns, the Cotswold, the Mendips, the North and South Downs, the Dorset Downs, and the Berkshire Downs, roughly converge upon Salisbury Plain. Of the importance of that site in the history of our island there is no space to speak here, but it is necessary to remember the disposition of the ranges in order to appreciate how great a rôle the South Downs must have played in the early history of Britain; for they furnished, as did the other three great chalk ranges (the Dorset Downs, the North Downs, and the Chilterns, with their continuation in the Berkshire Downs), the main routes of travel in early times. They were bare of trees, dry, and fairly even along their summits, and, save in a few places, they afforded a good view upon either side, so that the traveller could in primitive times beware of the approach of enemies.
The great mass of chalk which forms the Hampshire Highland splits, before the eastern boundary of that county is reached, into two branches; the northern one of these runs through Surrey, straight to the Medway in Kent, crosses that river, and turns down to meet the sea at Dover. The southern branch enters the county of Sussex just beyond Petersfield, and thence eastward forms this range of the South Downs.
There is no other stretch of hills precisely like them in Europe; their nearest counterpart is that other northern range formed much upon the same model, and of the same material, which looks at them from thirty miles away across the Weald. They run in one straight wall for sixty miles, maintaining throughout that length a similar conformation with a similar escarpment turned perpetually to the north; a similar absence of water; a similar presence from place to place of groups of beech-trees which occasionally crown their highest summits; a similar succession of comparatively low passes, and a similar though rarer series of what the people of the county call “gaps,” that is, gorges, or rather rounded clefts, in which their continuity is completely broken by the passage of a river. They are the most uniform, the most striking, and the most individual of all the lower ranges to be discovered in this island or in neighbouring countries. They might be compared by a traveller to the line of the Argonne, or to the steep, even hills above the Moselle before it enters German territory. But they are more of one kind than are even these united ranges. Coming upon
