A patriotic lady in New Jersey, to whom Aoftie;alltJr is under great obli gations, has addressed the following let ter to a member of the Horticultural So- esety of Pennsylvania, for the purpose of being laid before it, on the insects which destroy theproduce ofsome ofour fruit trees, and proposes large premium for the discovery of remedy for this great and increasing evil. The socie- ty, fully sensible of the importantnature of the letter, appointed a committee to report thereon; to tocorrespond with other Horticultural societies or the subject; and to endeavour to produce all the in- formation in their power in relation to the means ofpreserying fruits from the destroying enemy. With the IastEieW, the committee have thought proper to publish the letter, and will be pleased to receive communications on its contents from those who have it in their power to give useful information, or to contribute to the fund proposed to be raised as re- ward to the person who may be so for tunate as to discover the wished-for means ofsaving to the country the im- mense quantity of6ne fruit, that is amnu- ally lost, by the depredations of insects.

 As the writer of the letter wishes her name to be concealed, it is withheld; but 1t shall be communicated to those whowishtoundertake theproposed task, and to avail themselves of the inforna- ton respecting the nature and habits of the insects, which the writer, by close attention and long experience, possesses.

 Communications may he addressed to Dauid Landreth, Jun. Chesnut street, Corresponding Secretary ofthe PennsYl- vania Horticultural Society.

 By order of the Committee,

 DEAR SIR-It is about thirty years sineaI first tbecame aware of the fact, that eertainkinds of fruit fell from the tree be- fore they were ripe. Since that period, l have extended my observations, and 1 amquite convinced, thatalthough the se- verify of the winter may and does some times initire the fruits, yet the echiefcause of their frequent failures is the injury done to them by insects. l do not now allude to those which puncture the bark, either on the limbs or near the roots, nor to those which eat the leaves. They are ofvery little importance, mischievous as they are. Itis of those which attack the lruititself, thatI speak, and to which ] wish to draw your attention. There is scarcely member of your society that can imagine the extent of the evil which these insects produce, for themarlxetsare no criterion from which one might draw a proper conclusion. If these insects could be destroyed, there is every prob ability that unripe fruit, and such as is of an inferior quality, would be entirely banished from our cities, thereby great ly lessening the bills of mortality. But for these insects, cherries, nectarines, plums and apricots could be sent to mar ket for half a dollar a bushel, and of these, none but the finest kinds would be cultivated. As it is, these fruits are scarce and of high price, and as the in- sects generally choose the finest kinds forthemselves, the markets are crowded with that which is poor and unripe.- When we consider that fruit is no long CT luxury, but a necessary article of life, and that the heat of our summers renders it particularly grateful to all de- scriptions of persons, from infancy to old age-We ought to encourage every plan which has the cultivation of good fruit for its object. We must not judge that the evil of which ! complain is of a local nature, because some cuitivatorsw live within the limits of ia city, have been partially exempt from it. It is not from such small enclosures that city is to be supplied with fruit; nor is it to those who have but a few trees under their care that we must look for sympathy or hope for information. We must inquire of those who have planted large orchards, and who have, year after year, been careful to note the various accidents, dis eases, and depredations which ir;ure trees and cause their fruit to perish.- For myself, independently of several large orchards of apple, pear and peach trees, have upwards oftwelve hundred full bearing plum. nectarine and anri-
