These beds curve upward from observation that such grounds become soon dry after heavy on both sides, and, therefore, form a kind of trough or basin showers and long wet weather. Such soils and rocks are called at c, where the water, from the porous soil running on each arenaceous, or sandy, and easily “drink in" the water that side of the inclined planes B B, meet and gush out as a large falls upon them.
