We have from Parker Este, of Cobden, Ills., the premium lists of this great affair. As we have said before, the exhibition will be one no progressive horticulturist can afford to ignore. The Mexican government alone has taken five acres for its horticultural display. Excellent arrangements have been made for receiving and properly exhibiting anything that may be sent, and every arrangement is made for specimens of excellence in either large collections or single specimens. For instance, though $250 are offered for the best 200 varieties of apples, $6 are offered for the best plate of Baldwins, of Northern Spy, or of any variety known or unknown, and so with everything in fruits, flowers or vegetables. Every one interested in horticulture should send for programmes and instructions to E. A. Burke, Director General, New Orleans.

In the programme of classification, we find the following items of horticultural interest. Those who desire further details can correspond with Parker Earle, Cobden, Illinois:

Pennsylvania Horticultural Society

The May meeting was fully equal to the April one, of which we gave some account. On this occasion there were but two amateur exhibitors: Mr. Clarence H. Clark, whose gardener, Mr. Warne, had a collection of ferns, foliage plants and azaleas - one of these being six feet high by fifteen feet in circumference; and Mr. Jacob Paul Jones ,whose gardener, Mr. Bell, had a collection of herbaceous plants, in the cultivation of which he is quite famous. The commercial exhibitors were Mr. Evans, who, among other cut roses, had blooms of the Francis Bennett rose, which, by the way, the florists hereabouts insist on abbreviating to simply "The Bennett Rose;" W. H. Hanson, J. Kift & Son, Geo. Anderson, H. A. Dreer, Robert Scott & Son, Heron & Nisbet, Hugh Graham & Co., and D. Fergusson's Sons.
