plum ,-tae tylS6ctS ueStr0ycd uteat Gtts--- Besides this loss, the apples, quinces, cherries, and pears were so knotty from the plnctares of the same insects, that they were unfit toeat. When we think of the loss to city of twelve hundred bushels of such fine fruit-and from one farm only--we may imagine what It must lose. when, but for these insects, twelve thousand bushels might be taken to market.

 Asitis, veryfew persons cultivate any other fruits than apples and peaches; and these often suffer very materially, in certain seasons, from this very cause. in fact-so numerous have insects be- come, that two-tilirds of the apples have been injured by them during the last summer, and many hundred bushels of peaches have been rendered unsaleable in consequence of the gummy exuda- tio4s which dis6gured them.

 l have been for years employed, ex- IpensiYely, in attempts to destroy these insects, but have not yet been able to lessen their numbers. l have tried all manner of washes and fumigations, and have covered the orchards with as much of lime and ashes as the roots Of the trees would bear; and what seemed to promise most success, l have caused every particle of fruit to be picked up as soon as 1t fell.

 Thus disappointed, and believing that a remedy must exist somewhere-for these insects are neither poisonous nor invisible, have thought it best to apply to the different Horticultural Societies for aid-and as you was kind enough to interest yourself in my representations, and promised to bring the subject be- fore the Horticultural Society of Penn sylvania, have made the first direct ap- plication to you, trusting that you will not only bring the matter, properly, be- fore your own society, but that you will suggest the proprietyofis issuing circulars to all other Horticultural Societies in the United States.

 The plan which l would propose, is to offer premiuos for the destruction of these insects, and of such magnitude as to draw the attention of men of sci ence to the trial. think that a sum of two thousand dollars would not be too great, when we consider that two years of experienced labor must be devoted to the investigation.

 As to the mode of raising this sum, if nothing better is suggested to you, would propose that it should be done by subscription. would engage to obtain three hundred dollars myself-asling no more than one dollar from each sub. seriber.

 As two years would elapse before the experiment could be considered as fully tested, there can be no doubt, but that double the amount of the sum propose, could be obtained. The surplus of which, after the premium has been paid, might he held by your society, as pre- miums for the destruction of those other insects and vermin which destroy our grains and injure our vegetables.

 To assist any one who is willing to make the trial, l am willing to give all the information l possess. And as, by a laborious and long continued investi- gation, l have mpletelyidentifed these insects, and know their habits, l can much facilitate the experiments of those who strive for the premium.
