Penological Congress at Philadelphia. The fourth Pomological Congress, which assembled at Philadelphia on the 18th ult., and continued in session two days, was in several particulars a most interesting session. Its most important movement was the adoption of a constitution, under the title of the American Pomological Society. Delegates were in attendance from nearly all the Atlantic states, and from several of the Western, and they comprised, evidently, the chief pomological talent and experience of the country. The collections of fruits were very extensive - as a proof we may state, that in a hasty glance among the tables of pears, we observed 200 varieties from M. P. Wilder, 135 from Parsons & Co., 128 from B. V. French, 122 from J. S. Cabot, 140 from Ellwanger & Barry, 100 or more from Wm. Reid, 108 from Thomas Hancock, besides many other collections nearly as large. These included some specimens of much interest, and others of extraordinary beauty and fine growth. On the whole, the Congress was a very satisfactory one, with the exception of too short a time, (ouly two days,) allowed for its deliberations.

The provisions of the constitution were, bicn-nial meetings - a president, and vice-presidents from each state, territory, or province repre, sented - a treasurer and three secretaries - executive committee of five members - a standing fruit committee of five members in each state or territory, with a general chairman - a standing committee for native fruits, another for foreign fruits, and a third on synonyms, each consisting of seven members, and an admission for membership of two dollars biennially, or twenty dollars for life-membership.

A chairman was appointed for each state, with power to select his associates, consisting of the following gentlemen, with Samuel Walker, of Massachusetts, as chairman of the whole: Maine - Henry Litrlr, Bangor.
