Injury from Seventeen-year Locust. A Western Missouri correspondent writes: "What are called the seventeen-year locusts are hatching out here in great numbers and we would enquire whether they do much damage to nursery stock or not, and if so, if there is anything that can be done ? We think you had them East, a year or so ago, but we paid no attention to reports of them at the time. Any information you can give will greatly oblige." [This insect comes to the surface of the earth for the purpose of depositing its eggs, and then dying. It has a short, but merry life as a perfect insect. The eggs are deposited in the young branches. The young larva feeds on the branch, and by the time it is large enough to go into the ground, the twig breaks off, and in this way deforms the tree. Then the stock looks bad by the scar made on the bark by the act of oviposition. This is the chief injury. Where there are large forest trees, they often prefer the heights, to lower nursery trees. - Ed. G. M].
