Occasionally, even when they hear no sound, some fancy or conviction prompts them to jump hither and thither past and through the same objects, mixing the tracks as they retreat. The longest runners are those that are found on bare land, because they are exposed to view; the shortest, those found in thick covers, since the darkness hinders their flight. There are two species of hare. The common hare and a smaller variety of the same; which is said to be more brindled in colour than the larger kind. See The Hare in Fur and Feather Series, p.5.
