What sweet things must the autumn winds whisper to the tiny knotweed as they sweep along the coast, to make it tint the sandy plain with its delicate blush! And what a keen appreciation the little plant must have of the beauty dear to Dame Nature's heart to give out its bloom so abundantly ! It seems loath to leave us, and often lingers well on into the autumn.
