The strata h here crop out on the slope of the chalk hills, and the rainfalling upon them, unless rapidly absorbed, tends to drain at once from their surface into theadjacent valleys. V, L shows the line of valley level. This arrangement is not unfrequent between Kingsclere and Inkpen, and also between Guild -ford and Leatherhead.
