Our correspondence this month extends over a large region of country, and much of it is occupied by accounts of the effects of last summer's drought and the extreme variations of the past winter's climate. From Loudon County, Va, Yardley Taylor writes.

"As the last year has been remarkable with us, some statement of the effects may not be unacceptable; and first the drought, it is believed, was never surpassed. The depth of rain fallen for a year past certainly does not exceed two feet, more probably only twenty inches. But little snow occurred during the winter, and but one rain for twelve months that wet ordinary ground plough deep. Pastures were constantly dried up, so that farmers had to commence feeding stock a month earlier than usual, with our corn not one-third of a full crop. Though the wheat and hay crop was tolerably good, provender run out before the pastures were fit to turn in upon, and serious consequenoes for the coming year are apprehended. The grass in the early part of the season was very impoverishing, and in some places there is not half a crop. Virginia and Maryland usually send large quantities of corn to market, but the past winter and spring there have been tens of thousands of bushels brought up from tide water, so that the high prices of beef have had a cause.

The winter's effects on fruit trees have been remarkable. At mid-winter, two weeks of moderate weather swelled the buds and started the sap, and the severe season that ensued produced the results we now see in our trees; some branches of Apple, Peach and Cherry trees failed to put out leaves. The twigs seemed plump and green, but no circulation of sap. Some Peaches opened but few blossoms, while the leaf buds opened freely, except on the outer branches; the Grosse Mignone suffered most. The Cherry trees almost entirely failed to set their fruit; what could be the cause ?

A singular circumstance is observable on some fruit trees this year: a tendency to produce double fruit in both Plums and Peaches; one of my Peach trees has produced several instances of treble fruit from a single blossom, and on several small branches every bloom has set double fruit Why is this so? has it been that the amount of organisable matter usually laid up in the fall in the body of the tree, had to expand itself in the spring in less compass in consequence of the short growth of last year, and thus giving more support to the fruit buds. The same effect has been observed in other States. - Y. T".

It is observable that when Pear and other trees are forced to a second bloom the same year, those branches are unfruitful the next; the forcing the trees received in winter produced the same effect. The setting of double fruit our correspondent has satisfactorily accounted for. The present favorable season will probably put all to rights. - Ed.
