Protection of its natural enemies (weasel, stoat, polecat, fox, hedgehog, owls, buzzards, kestrels, the smaller sea- gulls). Catching in traps, etc., in the spring, when the voles are only present in small numbers. (b) Destructive measures, which should be as gene- rally used as possible in infested districts. If a field has been completely devastated, or the crop is over; (1) Working the soil with a spiked roller; (2) Partial inundation of the lower-lying fields. If it is desired to kill the voles and spare the crop as well, the fol- lowing means may be recommended: (1) The digging of cylindrical holes six inches across and two feet deep, especially at the margins of the fields and in the furrows, as well as—at harvest time—on any foot- paths that may be found. The voles fall into these holes, cannot get out again, and are starved. (2) The employment of poisons. (Care must be taken that no children or domestic animals are poisoned.) Phos- phorus paste is Fig. 25.—The Soiitliern Field Vole [Aroicdla, arvalis). The Sonthem Field Vole (A. arvalis) plays the same destructive part on the Continent that the preceding form does here (Fig. 25).
