The former cease to perform their normal absorptive functions, and from the leaf are gradually withdrawn the substances which are readily made soluble. The cell walls and the less useful parts are left, and by the formation of a distinct corky layer across the leaf-stalk, where it is attached to the main stem, the plant cuts off its assimilatory organs by a natural process, so that no wound or injury except the well-healed leaf-scar shall mark its fall. 1ti tliis |in«-. ss tlic chlorophyll is oxidized and changes frcMii i .1. v. i(,| These colors also serve very likely as a proti-ctmn to shield twigs and trunks from the hot autumn sunshine. Likewise, the twigs themselves may be provided with color for the same purpose. The old leaves are dropped in the autumn, but al- ready a new set of modified leaves in the form of bud- scales have been formed, in turn to be defoliated the next spring, after serving a term of winter protection.
