I now proceed to apply the first principle of which I spoke, that of examining a single county in the same way as others have examined the maps of England as a whole. I doubt if any county would prove more instructive for the purpose than that of Sussex, of which the settlement was developed in isolation and determined by well-defined geographical conditions. Whatever may be said of other suffixes, Mr. Seebohm has shown us that, even allowing for a large margin of unavoidable error, the terminations _-ing_ and _-ham_ are not distributed at random, but are specially distinctive of that portion of England which was settled by the earliest immigrants and settled the most completely. As a broad, general conclusion, this is virtually established. Now, if we turn to the map of Sussex and ask if this general principle can also be traced in detail, the first point to strike us, I think, is the close connection existing between the _hams_ and the rivers. The people, one might say, who settled the _hams_ were a people who came in boats. Although at first sight the _hams_ may seem to penetrate far inland, we shall find that where they are not actually on the coast, they almost invariably follow the rivers, and follow them as far up as possible; and this is specially the case with the Arun and its tributary the Western Rother. Careful examination reveals the fact that, while to the south, round Chichester Harbour and Selsea Bill, we find several _hams_, and find them again to the north in the valley of the western Rother, there are none to be found in the space between, which shows that the men who settled them found their way round by the Arun and not overland. I need hardly observe that the rivers of those days were far larger than the modern streams, and their water level higher. It is anticipating somewhat to point out that the same examination shows us a large group of _tons_ covering this district away from the river, where we find no _hams_. Evidently these suffixes do not occur at random.
