Show 312 than 200 yards from home. Their ravages begin as soon as the first green leaf of cereal or vegetable appears above tho ground, and cease only when the last kernel of grain has been carried away. With regard to their rate of increase I was informed by a farmer, though seven or eight was the usual number produced at a birth, he had in one instance on opening a female found no less than thirteen embryos. As they are known to produce two or more litters during the year, their excessive multiplication will thus not appear surprising. Poisoning by strychnine appears to be the only sure means for their suppression. This is neither easy nor always safe, since in exposing poisoned grain there is always danger of killing horses and cattle; and as the farmer and ranch succeed each other by turns, the extermination of these pests fails from lack of the necessary cooperation.
