The Broom-Squire by Sabine Baring-Gould

Mehetabel ran, neither along the way that led in the direction of Portsmouth, nor along that to Godalming, but to the Moor.

"The Moor," is the marsh land that lies at the roots of the sandstone heights that culminate in Hind Head, Leith Hill, and the Devil's Jumps. As already said, the great mass of Bagshot sand lies upon a substratum of clay. The sand drinks in every drop of rain that falls on the surface. This percolates through it till it reaches the clay, which refuses to absorb it, or let it sink through to other beds. Thereupon the accumulated water breaks forth in springs at the base of the hills, and forms a wide tract of morass, interspersed with lagoons that teem with fish and wild fowl. This region is locally known as "Moor," in contradistinction to the commons or downs, which are the dry sandy upland.
