After London by Richard Jefferies

At first Felix rode quickly, but his horse stumbling, though accustomed to the woods, warned him to be more careful. The passage of so many horsemen in the last few days had cut up and destroyed the track, which was nothing but a green path, and the covered wagons had of course assisted in rendering it rough and broken. He therefore rode slowly, and giving his horse his head, he picked his way of his own accord at the side of the road, often brushing against the underwood.

Still, indeed, absorbed by the feelings which had almost mastered him in the arbour, and thinking of Aurora, he forgot where he was, till the dismal howling of wood-dogs deep in the forest woke him. It was almost pitch dark under the tall beeches, the highest of the trees preventing the beams of the moon from illuminating the path till later in the night. Like a curtain the thick foliage above shut out the sky, so that no star was visible. When the wood-dogs ceased there was no sound beyond the light fall of the horse's hoofs as he walked upon the grass. Darkness and silence prevailed; he could see nothing. He spoke to his horse and patted his neck; he stepped a little faster and lifted his head, which he had held low as if making his way by scent.
