Let us note, too, how the really habitable strip of Sussex, from the point of view of an early people, was quite naturally cut off from all other parts of England by obvious limits. This habitable strip consists, of course, of the coastwise belt from Brighton to the Hampshire border (which belt I shall henceforward take the liberty of designating as Sussex Proper), together with the seaward valleys and combes of the South Downs. To the west, the great tidal flats and swamps about Hayling Island cut off Sussex from Hampshire; and before drainage and reclamation had done their work, these marshy districts must have formed a most impassable frontier. From this point, the great woodland region of the Weald, thickly covered with primaeval forest, and tenanted by wolves, bears, wild boars, and red deer, swept round in a long curve from the swamps at Bosham and Havant to the corresponding swamps of the opposite end at Pevensey and Hurstmonceux. The belt of savage wooded country, thick with the lairs of wild beasts, which thus ringed round the greater part of the county, shut off the coastwise strip at once from all possibility of communication with the rest of England. So Sussex Proper and the combes of the Downs were naturally predestined to form a single Celtic kingdom, a single Saxon principality, and a single English shire. It will be observed that this description leaves wholly out of consideration the strip of country about Hastings, Rye, and Winchelsea. It does so intentionally. That strip of country does not belong to Sussex in the same intimate and strictly necessary manner as the rest of the county. It probably once formed the seat of a small independent community by itself; and though there were good and obvious reasons why it should become finally united to Sussex rather than to Kent, it may be regarded as to some extent a debateable island between them. For an island it practically was in early times. At Pevensey Bay the Weald ran down into the sea by a series of swamps and bogs still artificially drained by dykes and sluices. On the other side, the Romney marshes formed a similar though wider stretch of tidal flats, reclaimed and drained at a far later period, partly through the agency of the long shingle bank thrown up round the low modern spit of Dungeness. Between them, the Hastings cliffs rose high above marsh and sea. In their rear, the Weald forest covered the ridge; so that the Hastings district (still a separate rape or division of the county) formed a sort of smaller Sussex, divided, like the larger one, from all the rest of England by a semicircular belt of marsh, forest, and marsh once more. These are the main elements out of which the history of the county is made up.
