Mr. Wilson Dennis, of Appleback (what a capital place to grow apples), Bucks County, Pa., sends us specimens of the Jackson Seedling Apple, with the description, as follows: "Tree a good grower, and bears early; fruit always fair, which will keep till June, and is in season from December till May. Growth of the tree rather upright - young wood, dark brown."This apple is known and esteemed by pomologists - so much so, that Dr. Brinokl6 had a colored drawing made of it, and has given us liberty to publish it with a description by himself. We can speak very favorably of the taste of these specimens.

The Gardening Books, and Books on Agriculture and Science, for sale by J. Q. A. Warren, of Boston, form a large and separate catalogue, embracing all the works on these subjects esteemed in this country.

Rhoads & Gray, of Lyons, Wayne Co., N. Y., have issued a catalogue of their extensive fruit and ornamental trees, with a "wholesale list," to which they ask attention.

The Jackson Apple #1

Philadelphia.

My dear Sib: The apple you received from Wilson Dennis, of Appleback-ville, Bucks County, Pa., and which you did me the favor to leave with me, I recognize as the Jackson. Other specimens from Mr. Dennis, of the same apple, were handed to me for examination.

This valuable variety originated with James M. Jackson, of Quakertown, Richland Township, Bucks County, Pennsylvania. My acquaintance with it commenced in March, 1851, at which time I received specimens grown by Mr. Jackson, who very kindly forwarded to me grafts from the original tree.

Annexed is the pomological description I promised to send you.

Size, medium, two and one-half inches by three and one-fourth. Form, roundish. Skin, greenish-yellow, with many dark green blotches and gray dots, a few very faint red stripes scarcely perceptible, and, on the exposed side, a warm, mottled-brown . blush, containing numerous white dots with a central gray speck in each. Stem, variable, from three-eighths to seven-eighths of an inch long by one-sixteenth thick, inserted in a deep, narrow cavity. Calyx, closed, set in a moderately wide, deep, and sometimes slightly plaited basin. Core, medium. Seed, gray, five-sixteenths of an inch long, three-sixteenths wide, and two-sixteenths thick. Flesh, greenish, fine texture, tender, juicy. Flavor, deliciously aromatic. Quality, "very good," perhaps " best." Maturity, from October to May. I inclose an outline.

Very truly yours, W. D. Brinckle.

J. Jay Smith, Esq.
