" When the ivy has found its tower, when the delicate creeper has found its strong wall, we know how the parasite plants grow and prosper. They were not created to stretch forth their branches alone, and endure without protection the summer’s sun and the winter’s storm. Alone they but spread themselves on the ground and cower unseen in the dingy shade. But when they have found their firm supporters, how wonderful is their beauty; how all-pervading and victorious! What is the turret without its ivy, or the high garden wall without the jasmine which gives it its beauty and fragrance? The hedge without the honeysuckle is but a hedge. "
