Sir; It is rather late in the season to inform you of the effects of the last winter, but as I do not observe any mention made of it by correspondents from Illinois, I will give you a few items - although September was a very hot and dry month, yet the winter came on so gradually that fruit trees and fruit would not have suffered but for the great severity of the freezing - the murcury in F. at several times went to 14° below zero, but especially on the 19th January when it reached 22° below zero. Of course we could not hope that the buds of the peach could resist such extremes, but we hoped that the seasonable weather in the beginning of winter had prepared the tender shoots to resist it - but it proved too much for them, and great numbers of young trees have wholly perished, while all nave suffered greatly - from one inch to three feet of the exflmitiea of the limbs having been killed. Strawberry plants that were not protected also suffered - particularly Hovey's Seedling - a strawberry that I received as Keen's Seedling, but which I think must be the Early Scarlet, has stood the winter well, and is the only one that has set any fruit - but much of that was killed by a frost on the 20th May. Rather a hard climate this for gardening and fruit culture - ten days ago to-day every tender plant that was not well protected, was destroyed or injured by frost - the mercury being down to 82° on the morning of the 20th, and to-day the direct rays of the sun have scorched and curled beans and the tender foliage of the pea - at three P. M., the mercury stood at 96 in the shade, free from reflection.

But all I wish to trouble yon, alter this long story about the difficulties of our climate, is to ask you or your correspondents for some remedy against an enemy to the strawberry, which is new to us here. It is a worm about an inch long when grown, dark colored with but few bristles, very active in its movements when disturbed, that rolls itself in the leaf by a web and then preys upon everything within reach giving a scorched and blighted appearance to a whole bed that previously was most luxuriant - it Is so wound up in the leaf that no general application of dry liquid will reach it - tobacco juice will destroy it when lmmerged in a pretty strong preparation of it - but it must first be taken from its secure hiding place in the leaf, but this process would be too much like the Frenchman's flea powder for practical application - it commenced its depredations about the time the bloom began to come out and continues yet.

I think it is the same worm that attaches itself singly to the foliage of fruit trees, and is so destructive to it. Some of your correspondents anticipated a very general destruction of insects from the severity of the past winter. It is commendable to see good in every occurrence, however unfavorable in appearance, but I fear that the stock of destructive insects has not been materially diminished here, for they seem unusually ravenous for every tender sprout, after their long torpid slate.

The Osage orange in this region, stood the excessive cold most satisfactorily - even seed-lings being but slightly injured It is fast growing in favor here, and will be the fence of this country in a few years, unless some unlooked for defect appears. There will be a few hedges turned out next spring, five years from the seed. Respectfully yours, fee. J. B. M. Warsaw, III., May 29, 1852.
