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.
When I had stood ten minutes, thinking and imagining, and getting my spirit in tune with the place, and in the right mood to enjoy the supernatural, a raven suddenly uttered a horse croak over my head.
