Some of our Oak-forests are older than history: such was the forest of the Weald—Anderides-leag—in which the aboriginal Britons so long withstood the attempts of Romans and English to conquer them, and which at a much later date supplied alike much iron from its quarries and the oak charcoal wherewith to smelt it; and of which to-day the pedestrian-tourist from London to the South Coast will cross many considerable fragments. How widely it was grown is evident from the vast number of place-names of which it forms part, such as Okham, Ockshott, Ockley, Acton, Acworth, Acrington, Okehampton, Oxted, etc.

Those bearing stamens are grouped on a long, slender and pendulous catkin; each consisting of a four- to seven-lobed calyx, within which are ten stamens. The females are solitary and erect, consisting of a cupule, within which is a three- to eight-lobed calyx, a three-celled ovary with three styles. The cupule becomes the familiar "cup" of the acorn, which again is the
