This little creature was noticed in several districts in Southern California. It lives in communities on the dry, sandy plains, where the herbage is of the scantiest kind. Its nature is shy and timid in the extreme, and so quick and agile are its motions that even when found some little distance from its hole it proves no easy task to shoot one. Usually their quick ears and roving eyes warn them of coming danger in time to secure an unimpeded retreat, and the glimpse of a white tail, which is held npright after the manner of an antelope, as its frightened owner disappears beneath the ground, is all one usually obtains.

They live together in large colonies, and in some portions of the State where their increase has been left unchecked, it seems, to one passing through, as if the country was one vast bnrrow, so rapidly do their colonies succeed one another. Ouce firmly established, the ireradicatioo is a matter of extreme difficulty. It is rarely possible to completely destroy a large colony, and if a few pairs are left they soon multiply to snch an extent as to make their ravages on corn- field or vegetable- patch serionsly felt; in sections where their numbers are greatest, I was informed that not infrequently the loss by these little indefatigable thieves had reached one- half the corn- crop. Their burrows are usually made in an uncultivated patch of ground, most often a pa store immediately adjoining cultivated ground, and their raids rarely extend more |
