As new varieties of grapes are occupying a good deal of attention at present, it may, perhaps, interest the readers of the Horticulturist to have a description of a new white grape, which seems to be perfectly hardy in this city, and of which the flavor is good - not equal, perhaps, to the finer foreign grapes, but still very good, being free from pulp and foxinees. Like many of our most valuable varieties of fruit, it was an accidental seedling which sprung up in a private garden in this city, and first fruited in 1857. Whether it originated from the seeds of the Sweetwater, Isabella, Black-cluster or Clinton, it is, perhaps, impossible to tell; but as it coincides perfectly in habit and foliage with the latter, it is probable that it is derived from that grape. However that may be, it seems to be as hardy as the Clinton; the small twigs on young plants, though unprotected, having been perfectly uninjured during the past Winter. The bunches are medium, shouldered, compact; berries medium, round, sweet, free from pulp, good flavor, white; ripe, middle of September. It was exhibited at the Fall meeting of the Fruit Growers' Society Of western New York, and elicited the warmest commendation of the Committee on Native Fruits, who did me the honor to name it the King Grape.

J. Jay Smith, Esq.: - A public journal like the Horticulturist is public property, and the same public who pay for it have a right to receive information from every page; personal differences have no business in it, unless they are so managed as to convey an equivalent amount of benefit to the subscribers collectively; and, even then, common courtesy ought to be shown by the debaters. Taking this view of the subject, I do not wish to offer any comments on Mr. Eaton's reply in the July number, headed " Facts in Grape Culture," but leave the public to decide the matter as it stands at present. I would, however, say to your correspondent that I am willing, with your permission, to discuss the points at issue with him, in a truly philosophical, and experienced practical manner, provided he will refrain from any personalities, and confine himself to real principles, without mixing up mere assertions, and thus enable us both to give the many readers of your widely spread journal the best knowledge we possess, and, perhaps, explain something of the right system of ventilating plant-houses.

Yours, most respectfully, Wm. Chorlton.

Mr. Editor: - I observed an article on evergreens in the May number of the Horticulturist, by H. W. Sargent, Esq., New York, in which be seems to think Cupressus Funebris cannot thrive under the direct rays of the sun. We have tried it the past three years with success, and consider it one of our handsomest and best evergreens; the severe winter of 1857 and 1658 browned it badly, but with the warm days of Spring it recovered its original color. With all due respect to Mr. Sargent, according to our experiment, it is the cold and not the hot sun which affects it. The other plants mentioned do very well with us also - -the English Laurel, which passed through the Winters of 1857 and 1858, uninjured, though very severe for this climate; the Heath-leaved juniper has passed the late Winter very well, without protection; gardenias and cape jasmines stood the past Winter without browning, but were generally killed to the ground the two former Winters. Verbenas have gone through the past Winter without injury; they were in full bloom April 15th. Hamilton J. Garter.

Editor Horticulturist: - In reply to the inquiry in the last number, for a means to prevent the bleeding of the grape-vine, I will give that which has always proved effectual with me. Cut the end of the branch bo as to take off sharp corners. Stretch over it, as a cap, a thin piece of gum-elastic, and tie tightly with a strong thread; over this put a piece of linen or muslin; tie that also closely, and the bleeding will be stopped. My first trials were without the linen; the gum stretched to the size of a hen's egg and burst, throwing out a fine stream of sap to the distance of a foot or more. Gum caps or thimbles, made purposely, would be much more convenient than sheet gum. Respectfully yours, J. Williams.
