The bogs of Denmark the examination of which by Steenstrap and Vaupell has presented such curious results with respect to the natural succession of forest trees appear to have gone through this gradual process of drying, and the birch, which grow freely in very wet soils, has contributed very effectually by its annual deposits to raise the surface above the water level, and thus to prepare the ground for the oak.
