influence of the range which backs them and by which they live. From these villages proceed the principal flocks of sheep; in one of them, Findon, is the principal sheep fair of the country. Their plough lands are commonly poor, from the admixture of the last slopes of the chalk; their wealth is in flocks and in folds. In the Middle Ages they added to this the pannage which the beech mast of their woods afforded to swine. Right along from the Hampshire border to where the Downs fall into the sea beyond Brighton, from Goodwood that is, through Halnaecker, Eartham, Slindon, Arundel, Angmering, Lancing, to Rottingdeane--or rather to what Rottingdeane used to be before the æsthetes turned it pure Cockney twenty years ago--runs this row of little ancient places which are the typical Sussex homes of all. They grew up, as did those others of which we have spoken, where water could be found, and also, it may be presumed, where there was some local opportunity for defence now forgotten; the growth of Arundel certainly depended upon these two factors, to some extent probably that of Slindon (which centres round its great pond), and it may be supposed that of Lancing as well. In their architecture these villages are, as it were, a physical outgrowth of the Downs. The oak, which one sees so commonly in the Weald, is but rarely present here; the roofs are of thatch, the walls of flint. Flint is, of course, the stone of the chalk, and the supply is unfailing because, by a curious phenomenon which has never been thoroughly explained, no matter how many flints are taken from the surface of the soil, others continue to “sweat up” through the chalk and to take the places of those that have been removed; there is never for very long a lack of surface flints in the fields adjoining these villages. There are some such villages in which every old building without exception, even the squire’s house and the church, are entirely built of flint, as are the boundary walls of the parks and of the farms. The material has, however (at least in the constructions of the last few centuries), one great defect, which is that the mortar does not bind it as strongly as it will bind brick or stone. This defect has been explained as being due to the extremely hard nature of the silex, for to bind material together it is essential that the binding flux, the mortar, should penetrate more or less into the pores of that which it binds, and for this reason brick and stone are [Sidenote: FLINT-BUILDING]
