reputable and stoutly maintained by precisely the same authorities, to wit, that the shells of which the Chalk Downs are composed are those of marine animals and were laid down under the sea. If this was the case it is impossible to see how the little rivers can have continued their erosion while the chalk hills were rising upon either side, for no rivers run along the bottom of the sea. The fact is that this, like ninety-nine out of a hundred other geological theses, reposes upon mere guesswork; we have no evidence worth calling evidence to tell us how the contours of the land were moulded. The last of the Sussex rivers stands quite outside the scheme of those with which we have been hitherto dealing. It is the Eastern Rother, which rises, indeed, on the same Wealden heights as the others, but does not encounter the chalk hills, for these come to an end west of it in the cliff of Beachy Head. The Eastern Rother runs, therefore, not through a gap but a wide plain, which is marked off on the coast-line by the flats of the marshes before Dunge Ness. This little river nourishes no considerable town, but a great number of very charming villages stand either upon it or above it; others also less charming, as for instance the somewhat theatrical village of Burwash, whose old church tower, avenue of trees, and Georgian houses, have bred a crop of red-brick villas. Robertsbridge, however, is a paradise for any one, and contains or did contain in the cellars of its principal inn, the George, some of the best port at its price to be found in England. Within the drainage area of this river also stands (upon the Brede, a tributary) the height which was known until the Norman invasion as “Hastings Plain,” but has, since the great conflict, supported the abbey and the village of Battle. The harbour mouth of this river is the town of Rye, a haven which it is still possible to make, though with difficulty, but which was until quite the last few generations a trading-place of importance. With the mention of the Eastern Rother our survey of the river system of Sussex must close, for, though tributaries of the Wey rise within the political boundaries of the county, while the source of the Mole is also within those boundaries, their systems properly belong to the Thames valley and to Surrey. We have now some idea of the general configuration of the county, of the nature of its [Illustration: RYE] [Sidenote: GENERAL VIEW OF THE COUNTY]
