The hum of this singular insect fills the woods and gardens of Maryland at the present time, and the country there is alive with them. Though the Seventeen year Locust only appears during this long interval, the people of the districts favored by the visitation, congratulate themselves that the visits are so few and far between - for neither the ceaseless drone of the insect, nor the havoc it causes in ploughing up the young branches of trees, are among the pleasant experiences of country life.

It is a mistake of many persons to suppose this insect feeds upon vegetation. It feeds upon nothing during its three or four weeks of existence above ground, but is occupied solely with paring, singing its song, (or more correctly beating its drum - which is really the way in which the sound is made,) and laying its eggs in the tender branches of the trees. These young branches, which finally strew the ground beneath the trees, fall from the trees, broken by the winds at the weak place made by the punctures of the female in laying her eggs - and are not eaten off by the insects as many suppose. The actual food of the Seventeen Year Locust is made long beforehand, and consists of the roots of trees, as it appears by the careful examination of naturalists. Miss Morris, of Germantown, well known for her investigation of insect habits, has well settled the point that these locusts are a busy devourer of the roots of trees when they descend and take up their long abode underground. She thinks, from examination of the roots of many trees in the locust districts, that the larvae do more

Fortunately the Cicada Septenderem does not occur all over the country at once - but in different portions upon different years. There is no longer any question, however, as to the fact that each brood remains seventeen years under the surface of the earth. The insect is not a true locust like our annual insect of that name, or those which ravage the East, devouring the herbage, but a Cicada or larvent fly - equally as large and a good deal resembling a true locust.

The Seventeen Year Locusts #1

Much has been said about the harmlessness of these Locusts, which we were disposed to put faith in. Their history, undoubtedly, is a wonder; one of the most striking, indeed, in the whole range of insect life; but recent observation has compelled us to put them in the same category with the curculio, the wheat fly, the cut worm, and other destructive pests, to be destroyed without mercy. The woods in some portions of New Jersey look as if a fire had passed over them. The ovipositing of the Locust is not confined to the young wood of the present year, as is generally thought; we have seen innumerable instances of it in wood two, three, and four years old; we have also seen hundreds of younug pears, applet, ornamental trees, shrubs, etc, completely cut of by them, the incisions, in many of the young trees, being carried down the body of the tree to within a foot of the ground. Many of the limbs were dead, others were dying, and the probability is that many young trees will be entirely destroyed. It is too soon yet to speak confidently of the extent of the injury sustained, but it will no doubt be considerable.

We hope that the trees, etc., in the breadth of country occupied by the Locust, will be carefully examined and the amount of injury noted, and that all the facts will be carefully put on record, so that the history of the insect may be more precisely known, and the necessary measures of protection taken when it makes its appearance again seventeen years hence.
