He whipped up his horse and glanced sideways again.

And then he saw quite distinctly where a ray from his lamp leapt a low stretch of hedge, the curved back of--some big animal, he couldn't tell what, going along in quick convulsive leaps.
He says he thought of the old tales of witchcraft--the thing was so utterly unlike any animal he knew, and he tightened his hold on the reins for fear of the fear of his horse.

Educated man as he was, he admits he asked himself if this could be something that his horse could not see.
Ahead, and drawing near in silhouette against the rising moon, was the outline of the little hamlet of Hankey, comforting, though it showed never a light, and he cracked his whip and spoke again, and then in a flash the rats were at him! He had passed a gate, and as he did so, the foremost rat came leaping over into the road.

The thing sprang upon him out of vagueness into the utmost clearness, the sharp, eager, round-eared face, the long body exaggerated by its movement; and what particularly struck him, the pink, webbed forefeet of the beast.

What must have made it more horrible to him at the time was, that he had no idea the thing was any created beast he knew.
