"Every year orchards and farm crops in many parts of the United States are injured seriously by meadow mice and pine mice. The damage will be even greater next winter unless prompt measures are taken as suggested in the following pages. Among the sections recently reporting damage from these pests are parts of Arizona, Montana, southern Ohio, Pennsylvania, Virginia, and West Virginia. In a single county of Virginia, apple growers report that during the winter of 1916-17 trees valued at $100,000 were destroyed by pine mice. Much of the loss is due to the shortsighted policy of destroying snakes, weasels, hawks, owls, and other natural enemies of mice... Various phases of controlling the ravages of meadow mice and pine mice are dealt with in this bulletin"--P.[2]
