Should the reader be interested in the various ways in which the dehiscent fruits discharge their seeds, he will do well to collect a number of species, as yet unopened, and expose them to the sun in a dry place. He will then be able to note not only the directions and extent of the dehiscence, but also to observe the forcible ejection of seeds by those which split elastically, or which, by other mechanical contrivances, have the power of throwing their seeds a considerable distance. We may find still another subject for study in the beautiful autumn tints assumed by the leaves of many plants. Such tints are, of course, most conspicuous in the foliage of our forest trees and shrubs; and, when speaking of these, we shall have a word or two to say with regard to the nature of the internal changes that give rise to the beautiful display of colours; but not a few of the hedgerow herbs and shrubs exhibit tints equally rich and varied. Note, for instance, the pretty Herb Robert, still in flower in sheltered places, its blossoms standing out beyond a background of richly-coloured leaves. The vigorous summer growth of flowery banks and hedgerows is often closely trimmed with the sickle for the greater convenience of pedestrians and vehicular traffic, all the flowers and overhanging twigs being closely cut, and the wayside thus destroyed from the Nature-student's point of view; but the ground so denuded has recovered itself by the autumn, and a second crop of flowers, arising from the old stocks, often later than their normal season, is frequently the result. A considerable number of summer flowers continue to bloom during the autumn months, while a few are truly autumnal, and are not to be found till the summer has nearly or quite passed. In corn-fields we may still meet with the beautiful Pheasant's-eye (_Adonis autumnalis_), and in fields the Hairy Buttercup (_Ranunculus hirsutus_), the Daisy (_Bellis perennis_) and the Red Hemp-nettle (_Galeopsis Ladanum_) are yet in flower, while the Annual Meadow Grass (_Poa annua_) continues to produce new flowers to the end of the year. On sunny banks in chalk districts we still see the delicate Rock Rose (_Helianthemum vulgare_); and on banks almost everywhere the Wild Clary (_Salvia Verbenaca_), and the still more hardy Milfoil (_Achillea millefolium_), Knapweeds (_Centaurea nigra_ and _C. Scabiosa_), Field Scabious (_Knautia arvensis_), Dark Mullein (_Verbascum nigrum_) and the Toadflax (_Linaria vulgaris_).
