Bag Worm--remedies

How often does the simple knowledge of an msect'a habits and transformaron give the clue to ts easy destruction ! - By plueking and burning the cases of tbe bag worm in the winter time, the trees can be easily rid of them. If this is done whenever the first few bags ars observcd, the task of plucking is light; bot whero not so done, the wonns still continue to inerease, and parïly dufoliating tbe tree each year, slowly, but sureJy, sap its life. For many years this insect had been multiplying in the city of St. Louis, until in 1868 it had becoine exceedingly abundant aod destructive, espeoially in the older portions of tbe city. So many trees were unhealthy, and dwiodlod or died, that treo planters frequeutly became disconraged. Very few persons, however, suepected that the bag worm was tho cause, and still fewer were aware how easily its ravages wei e checked, until last winter, the junior editor ciillcd atteution to the matter through the colamus of one of the daily papers, and urgcd the destruotioo of tbe bags and their contenta bet'oro the trees again put forth their This appeal, we are glad to say, was duly responded to by tbe citizens; for, ia less than a month, the trees in the public parks and around the court-house, and also aloog many of the streets, wero entirely cleared of the bags. Indeed, we have seldom knowu eutomological isiformation to be fraught with sucú immediate aud benetïoial re nlts 1 It even opened up a new field of employment for cer!aia enterprising youths, who, with a dirty copy of the daily already referred to. in hand,might have been seeü trotting up some of the principal avenues, and shricking out newsboy fashion : "Clean your bagworms ofF, ma'am. " ''Clean your trees, ir ? - tako 'em all ofi for a doller !" Though the very Êrst efiorts of the new-hatched worm are direoted to building for itself a covering, and thrnigh, tbroughout its larval life, it is always eovered and protected by this covering, tbis insect is yet subject to the attaoks of parasites, two of which are already kuown to assist us ia subduine it. -
