Army Worm Moths entrapped in a Spider's Web. (Original). To the action of these various natural checks is doubtless due the seemingly strange appearance and disappearance of this vexatious pest. Nature strives ever to keep a balance in her affairs, and when an insect becomes too abundant, she mar- shals her various forces to bring it into subjection. I REMEDIAL AND PREVENTIVE MEASURES When an outbreak of army worms is first noticed, if it is con- fined to a limited area it is generally well worth while to cut down the grass or grain infested. The worms will remain beneath its shelter for two or three days, and as soon as the cut grass or grain is dry enough it should be burned, thus destroying the pests and preventing the invasion of neighboring fields. The worms may also be destroyed by spraying them with strong.
