Mole.

"And here is a mole-trap," said Jimmy, "with a mole in it. What smooth glossy fur it has! It will set whichever way you rub it."

"Yes; and don't you see the use of that. It can run backwards or forwards along its narrow burrows with the greatest ease. It could not do that if the fur had a right and a wrong way."

"Can it see?" asked Jimmy, pointing to the tiny black specks which represented its eyes.

"Oh yes. Not very well, I dare say; but well enough for its own purposes. It can run along its passages at a great speed, as people have found out by putting straws at intervals along them, and then startling the mole at one end and watching the straws as they were thrown down."

During the autumn and winter the mole resides in a fortress, often at short distances from the burrow where it nests. This fortress is always placed in a position of safety, and is of a most complex construction. It is a hillock, containing two or three tiers of galleries with connecting passages, and from the central chamber it has passages, or rows, extending in different directions.
