Excerpt from An Economic Study of Field Mice (Genus Microtus)
The present paper deals with the habits of the common field mice of the United States, the conditions which often favor their enormous multiplication, the natural enemies which aid in their repression, and the agencies which farmers may employ to avoid losses by the animals. Small as these pests are, they inflict enormous injury upon the crops of the country. The aggregate loss to the farmers from this source averages not less than three millions of dollars annually, and in some years is much greater. The major portion of this loss is preventable, and the object of this bulletin is to acquaint farmers, orchardists, nurserymen, and others with the most practical pre ventive methods.
