At a meeting of the Executive Board of the Pennsylvania State Agricultural Society at Harrisburg, a communication was received from Gen. James Irvin, offering the Board from two hundred to two hundred and fifty acres of land in Centre county, near the geographical centre of Pennsylvania, for the purposes of a State Agricultural School, provided the same is located thereon. This species of liberality is but too rare ; a gift of this kind in this neighborhood for a Horticultural Garden and School for young gardeners would be gladly chronicled.

"It is one of the features of our rapidly progressive sub-arctic climate, that the summer fruits are almost ripe, before one can report certainly upon the effects of the winter and spring frees ing - we have now advanced so far into the summer that things may be considered established, unless we get a very untimely frost which sometimes has happened even later than this.

The wheat in this region protected by the heavy snows has been but little winter killed and looks unusually fine and flourishing - there has been a great deal of it sown and the yield will in all probability much exceed the ordinary crop.

The Apple orchards blossomed in moderation, but the fruit has set remarkably well and there is a prospect of an abundant supply. Pears and Quinces also make a good show of fruit The better kinds of Cherries did not bloom, though some of the hardier varieties seemed to hare suffered but little. The poor Peach trees showed a sad amount of dead wood in April, and May has not much improved them - though the limbs are not killed outright; the buds, both wood and blossom were nearly all destroyed and the trees will look ragged until a new set are formed.

I think the trees will survive the freezing they have got, although they will be enfeebled and damaged by it The lateness with which many of them came into leaf has saved them from the curl, and if they are subjected to no unfriendly weather hereafter, the damage may be less than we at first anticipated - a few stray blossoms here and there show themselves, but (except from some of the hardy country seedlings which are good for nothing) it is settled we shall have no Peaches. The Currant bushes are full of fruit, and the Strawberries full of blossoms, though the latter as well as our meadows would be the better for rain.

The winter has acted singularly on vegetation - thus, the Pawlonia and Osage Orange, which generally freeze in part, are putting out leaves to the very extremity of their branches.

We are having dry, musky, Indian summer weather at present, and though the subsoil is not very dry, we need rain to establish the grass which started well, but which now threatens to be light.

Knowing the interest you take in fruit culture generally, must be my apology for this infliction. Hoping you have as little to mourn over in your section, as we have in our orchards, I remain, very respectfully, A. Huidekoper. - Meadville May 29, 1855.

P. S. - I have got my vines nicely in bloom and hope to make a good report of them in August"

A day or two after our friend's letter was written, his section of country and indeed a great part of New York, Pennsylvania and Ohio, enjoyed the benefit of an abundant rain. - B.
