One of the most interesting animals to be found anywhere is the mole. Moles live in every part of the United States and there are about 30 different species. But they are so seldom seen by people that they have become a kind of mysterious creature.

You can find a mole by looking for the long ridges of cracked earth it makes across fields. This is the roof of its tunnel, for the mole spends its whole life in darkness under the ground.
