The eighth biennial session of this Society opened at Philadelphia on the 11th of September, and continued three days. The morning session was occupied chiefly in organizing, and appointing a nominating committee. In the afternoon, the President, Marshall P. Wilder, Esq., delivered his address, the principal part of which will be found elsewhere. At the close of the address the nominating committee reported, and the officers were elected. President, M. P. Wilder, of Boston. Treasurer, T. P. James, of Philadelphia. Secretary, Thomas W. Field, of Brooklyn, L. I. We endeavored to get an official list of the officers and standing committees, but failed to do so.

The session just closed lost some of its interest from the fact that the list for general cultivation was not touched, the President having recommended that the duty of revising this list should be referred to special and local committees, to report at the next meeting. This we regard as the most important step yet taken by the Society. If these committees shall faithfully perform their duties, something will at last have been done worthy of a national Pomological Society. We purpose helping these gentlemen a little by and by. Their labors will be of the most onerous kind, but we hope they will not flinch from them.

The discussions which followed were rambling and discursive, but some interesting facts were brought out. We find it necessary to condense our reporter's remarks.

An amendment was made to the Constitution, reducing the life-membership fee from twenty to ten dollars. The discussions were then begun, the first in order being the Apple, It will be remembered that the list for general cultivation was not brought up at any time, the discussion being confined to varieties which promise well. The leading members having expressed their opinions, the following were added to the list of apples which promise well: Summer Sweet, Paradise, Canon Pearmain, Fall Wine, Early Joe, Willow Twig, Limber Twig, Bonum, Stan-sill, White Pippin, Pryor's Red, Keswick Codlin, Rawles' Jeanette, Maiden's Blush, Pomme Royal, Summer Queen.

The Currant was next taken up, and a warm discussion ensued in regard to the merits of the Cherry. Messrs. Wilder, Downing, Hovey, Lawton, and others spoke of it as being excessively acid, and destitute of flavor; while Messrs. Barry, Hooker, Warder, and others spoke in its fa-vor; and it was finally left on the list, to which were added the Versailles, Fertile d'Angers, and Imperial Jaune, a new French variety.

Strawberries were next taken up, and an interesting discussion followed, in which the opinion was expressed that a distinction should be made between the foreign varieties; that while those from England bad almost invariably proved ill adapted to our climate, those from France and Belgium had, on the contrary, proved very promising, as instances of which the Triomphe de Gand and others were mentioned. The Triomphe de Gand was spoken well of by every body, and this and Jenny Lind were added to the list.

Raspberries were next in order. The Allen, after a warm discussion, was placed on the list of rejected fruit. The Belle de Fontenay was placed on the list which promises well, and the Hornet was well spoken of. The Purple Cane or American Bed was highly commended by Mr. Downing.

Gooseberries

The Downing was added to the list.

Blackberries were brought up, several new kinds spoken of, such as the Grape, Parsley-leaved, etc, but none added to the list.

Grapes

This subject proved the most interesting brought before the Society. The Taylor and Maxatawny were added to the list. The Clara was thought too tender for out-door culture. The To Kalon was said to mildew and rot badly in some localities, but was thought good when perfect. The Clinton was spoken well of by Messrs. Hooker and Prince, but others seemed to think little of it. Pauline was recommended by several Southern members as a fine grape. The Massachusetts White met with little favor from any body. Allen's Hybrid was spoken of by several, and the merits of the Anna, Ontario, Rogers' Seedlings, and others were freely discussed. The Delaware met with encomiums, more or less warm, an all hands.

On Grape-culture a great variety of opinions were expressed, each man seeming to have a system of bis own. On some points, however, there was much unanimity, and some interesting particulars were elicited in regard to trenching, manuring, etc.

Pear-culture, however, brought out a greater variety of opinions than any other subject; some of them, indeed, curious enough. One gentleman thought moisture had more to do with the growth of plants than manure, the impression being that manure was of no consequence where moisture was abundant. Our reporter may have failed to catch his idea. Dr. Boynton gave some lengthened remarks on his mode of using manures for the pear, including a number of salts, by the use of which he claimed to have given his pears a high color and glossy appearance.

The Treasurer reported a balance on hand in 1858, $258.94; received September, 1860, $357; the total amount of expenditures $418.30; leaving a balance of $197.64 in the treasury.

The Standing Committees were announced by the Chair, which we shall publish as soon as we can get them. Boston was selected as the place for holding the next meeting.

The following resolution was passed: Resolved, That the thanks of this Society are tendered to Mr. T. P. James, Mr. J. C.Mitch el, and Mr. Wm. Saunders, the committee of arrangements for the meetings of the Society, for the excellent accommodations and polite attention which its members have enjoyed.
