"Earth" of the Fox
Mother fox bringing food to its young. The fox is a well-known burrower, its "earth" being familiar to many by by sight, and to all by name. Few persons, who do not know the history of the fox, would believe it to be capable of forming excavations of such extent. The fore feet of the mole are clearly formed for digging, their sharp claws penetrating the earth, their broad palms acting as shovels, and their powerful muscles giving the needful force. These limbs are essentially used for digging, and are but little employed as means of locomotion. But the fox is an admirable runner, as any hunter can avouch, and its fore limbs are formed for speed and endurance, their length enduing them with the one quality, and their muscular lightness with the other. Yet, just as the digging limbs of the mole are used fr locomotion, and enable the animal to proceed at no contemptible speed, so the running limbs of the fox are used for digging, and e nable the creature to excavate burrows of no contemptible dimensions.
Fortress of the mole
Of all the mammalia, the Mole is entitled to take first place in our list of burrowers. This extraordinary animal does not merely dig tunnels in the ground and sit at the end of them, but forms a complicated subterranean dwelling-place, with chambers, passages, and other arrangements of wonderful completeness. It has regular roads leading to its feeding grounds; establishes a system of communication as elaborate as that of a modern railway, or to be more correct, as that of the subterranean network of metropolitan sewers; and is an animal of varied accomplishments.
A prairie dog town
The burrows are of considerable dimensions, and evidently run to no small depth, as one of them has been known to absorb five barrels of water without being filled. They are dug in a sloping direction, forming and angle of about forty-five degrees with the horizon, and after descending for five or six feet, they take a sudden turn and rise gradually upward. The prairie dog has not the privilege of possessing a home exclusively devoted to its own use, for the Burrowing Owl, and the terrible rattlesnake, take forcible possession of the burrows, and devour the inmates, thus procuring board and lodging at very easy rates.
