One thinks Heidelberg by day--with its surroundings--is the last possibility of the beautiful; but when he sees Heidelberg by night, a fallen Milky Way, with that glittering railway constellation pinned to the border, he requires time to consider upon the verdict. One never tires of poking about in the dense woods that clothe all these lofty Neckar hills to their beguiling and impressive charm in any country; but German legends and fairy tales have given these an added charm. They have peopled all that region with gnomes, and dwarfs, and all sorts of mysterious and uncanny creatures. At the time I am writing of, I had been reading so much of this literature that sometimes I was not sure but I was beginning to believe in the gnomes and fairies as realities. One afternoon I got lost in the woods about a mile from the hotel, and presently fell into a train of dreamy thought about animals which talk, and kobolds, and enchanted folk, and the rest of the pleasant legendary stuff; and so, by stimulating my fancy, I finally got to imagining I glimpsed small flitting shapes here and there down the columned aisles of the forest. It was a place which was peculiarly meet for the occasion. It was a pine wood, with so thick and soft a carpet of brown needles that one's footfall made no more sound than if he were treading on wool; the tree-trunks were as round and straight and smooth as pillars, and stood close together; they were bare of branches to a point about twenty-five feet above-ground, and from there upward so thick with boughs that not a ray of sunlight could pierce through. The world was bright with sunshine outside, but a deep and mellow twilight reigned in there, and also a deep silence so profound that I seemed to hear my own breathings.
