Many of the species are found as adults early in spring, while I have found others in September. None of them are known to be injurious. REMEDIES. The question of remedies against the "locust," or short-horned grasshopper, is an important one, not always easy of solution. As the country is brought into more complete cultivation the '' grasshopper'' pest will natu- rally decrease, injury from the migrating forms only remaining to be dreaded. In the general life history it was said that a large proportion of the eggs are laid in fall, remaining unhatched during the winter. The young nymph, or larva, is a feeble insect, able to dig to the surface through the way opened by the pod, or through loose soil, but scarcely otherwise. Fall-plowing the infested land is therefore a most effective remedy. If the pods are deeply cov- ered, the young die attempting to get to the surface ; if lightly covered or exposed, their natural enemies find them easily ; and when the pods are broken, rain and sunshine induce decay or disease, and the eggs never hatch. Where grasshoppers other than the migratory forms are troublesome, systematic fall-plowing will effect a prompt reduction in their numbers. Special or lim- ited localities, like cranberry bogs, are sometimes infested, and in such cases turkeys are effective. They prefer grasshoppers to almost any other food, and, if allowed to run where such abound, will eat nothing else. In some cases the arsenites may be used to protect crops which are easily sprayed, and occasionally '' driving'' will answer for the fledged insects. Larval forms in grass or short vegetation can be collected in large pans or "hopper-dozer
