New Rochelle, August 14, 1861.

Mr. Editor. - Dear Sir: The cold snap of last winter destroyed, to a great extent, the fruit-buds of all the Blackberries, wild and cultivated, in this neighborhood. No other part of the plant appears to be injured, and they are growing as usual, with some fruit on the late or second blooming. My crop of fruit is so small that I consider it a total failure. Cherry-buds were blasted in the same way. I have quite a large variety, and my trees are healthy, and in full foliage. Very little fruit was formed, and I did not gather a pound. The Wild Cherry trees are thriving, and are well laden with fruit. Apple trees fine, and generally in full bearing, and do not seem to be in the least injured by the cold or insects.

I have seen no nests of worms upon trees - none upon the grape-vines - and up to this time we seem to have entirely escaped from the ravages of the various tribes of destructive insects, and I do not hear any complaints in regard to the potato.

The late rain has been quite refreshing, and vegetation generally in our neighborhood was never more luxuriant and beautiful at this season of the year. Mercury this morning at eight o'clock 66°, and has not been above 84° this summer, and but four days as high as 80°.

[Thus writes Mr. Lawton. New Rochelle is a beautiful place, and would seem to be also, in many respects, a very favored one. In common with others, it has lost its Blackberries and Cherries, but has a good show of Apples. Its freedom from insects and the effects of the drought is remarkable; and then the thermometer has never been above 84°, while all around have been dried up, and burned up, and eaten up. Look out for us, Mr. Lawton, at the next "heated term." - Ed].

I would like to know from the Editor of the Horticulturist the name of the best white native Grape, exclusive of the Rebecca. Will you please hand him this slip, and oblige a New Subscriber.

[The above is a postscript to a letter received by the publisher. It is from a subscriber living North, and we answer him by naming the Cuyahoga. We think highly of Allen's Hybrid from the little we have seen of it. The Maxa-tawny we also consider a fine Grape; but it will require a climate considerably south of New York to ripen it. The Anna is likewise fine, but it must be grown some distance south of your home. So, too, the Manhattan. These are all green (or white) Grapes- Ed].

Mr Dear Editor:- "There's husbandry in heaven," if not on earth. The season in this region is maturing in perfection the old White Doyenne Pear on trees upwards of fifty years old, the fruit of which the last twenty-five has been subject to a disease worse than the plague of Egypt or the Asiatic Cholera. This peculiarity of the season has reference to the county. In the city this variety has always maintained its original excellence. Very truly yours, Baltimore, Aug. 1st, 1861. Many Years a Maryland Subscriber.

[This is good news indeed. We wish we could venture the hope that this fatal disease had reached its "climacteric," and that hereafter this noble Pear is to enjoy an immunity from the blight which makes its cultivation in many places almost hopeless. Has any similar condition of this pear been noticed elsewhere? - Ed].
