turn, covered by a minute network of still smaller veins. The Sycamore leaf does not present the variety or possess the attraction of many other leaves for the lover of Autumn. The change of colour is generally indicated by the advance upon the tops of the lobes of a very light brown or drab tintsometimes merging into brown and occasionally red enough-though only occasionally-to warrant Cowper's designation of scarlet. Set off against the dark green hue of the summer leaf the effect is often picturesque—the tinting penetrating the tissue, and although shown most prominently upon the dark, upper surface of the leaf, also, though less conspicuously, noticeable on its paler underside. As the discolouration advances it takes possession of the spaces between the principal veins, the lines of tissue however on either side along the course of the principal veins remaining green longer than any other portion of the surface and forming an effective contrast with the decaying brown. |
