This took place at the Brooklyn Academy of Music, on the 18th, 19th, and 20th of September. It was seriously thought, at one time, of suspending the fall exhibition; but we esteem it a fortunate circumstance that this purpose was abandoned; otherwise, we should have been deprived of the pleasure of witnessing the most satisfactory exhibition that the Society has yet held. The exhibition room, though a very suitable one in most respects, is quite too small. All the plants could not be got on the table, and the mass of visitors were so crowded together as to interfere seriously with sight-seeing and enjoyment. This drawback, we are told, will not occur again. The lateness of the hour will prevent us from giving such an extended notice as we could wish. Mr. Menand, as usual, was present with his fine collection, embracing Caladiums, Begonias, Marantas, Crotons, Aralias, Dracaenas, Protea cyanoides (in bloom), Ferns, Bananas, Pavetta borbonica, Grevillea lon-gifolia, and many others, all very carefully grown.

Mr. Bridgeman, of Astoria, loomed up unexpectedly strong, and in collections made a very decided demonstration; for example, he had 13 kinds of Begonia, 15 of Caladium, 4 of Arau-caria, 4 of Croton, 4 of Dracaena, 11 of Maranta, 4 of Pteris, and 10 of Selagi-nella, Solanum quitense (a fine plant), Vallota purpurea (in flower),. Ferns, and a large number of other plants in pots; also, a splendid show of Gladioli. We will just say here, that the Gladiolus, as at present improved, is one of the yery finest of all show flowers. Parsons & Co., of Flushing, made a very large and fine display of pot-plants, among them some new and beautiful things, one of the most noteworthy, and one of the finest plants in the room, being the Alocasia metallica, with large, dark, metallic-looking leaves of great lustre. We also noticed in this collection Cyanophyllum magnificum, three species of Cissus, Pa-vetta borbonica, Pteris argyrea and tri-color, Caladiums, Begonias, Marantas, Ferns, and many others. From Isaac Buchanan & Son, of Astoria, a miscellaneous collection of plants, such as Caladiums, Begonias, Ferns, Bilbergias (in bloom), Alocasia metallica, a number of Orchids (Oncidium papillio and others being in flower), Marantas, and others.

Mr. Humphreys, of Brooklyn, a collection of plants, such as Begonias, Caladiums, Ferns, Sago Palm, Screw Pine, and other pot plants, besides some very pretty Wardian cases. Mr. Weir, of Bay Ridge, exhibited Caladiums, Begonias, Marantas, and other pot plants; but after leaving the large collections it was difficult to say to whom the rest belonged, owing to the defective labeling. Mr. Hamlyn sent, as usual, a fine collection, consisting of Begonias, Caladiums, Ferns, etc., Caladium Chantinii having been grown in the open air. There were also several other smaller lots from other parties, their names not appearing.

In Cut Flowers, Mr. David Clarke, of New York, made the best show, followed closely by Mr. Messelberg of Brooklyn. There were also cut flowers from Mr. Burgess, Mr. Brunner, Mr. Weir, and others. In Roses, Dailledouze and Zeller led off with a splendid display, which was kept fresh during the exhibition. They not only have a very choice collection of Roses, but they show a spirit as exhibitors which we should be glad to see more common. Mr. Clark, of New York, Mr. Burgess, of Brooklyn, and others, also had fine stands of Roses. Mr. Burgess made a large and fine display of Dahlias, his seedling, Mrs. Burgess, being one of the best. Mr. Brunner, of Llewellyn Park, also made a fine show. Mr. Pell, of the New York Orphan Asylum, likewise presented a large table of Dahlias; and there were some small collections. The display of Bouquets and Baskets was a very pretty feature, the exhibitors being Messrs. James Mallen, Andrew Bridgeman, James Weir (father and son), Walter Park, Isaac Cummins, Philip Zeh, and others. The judges this year adopted promiscuously arranged Bouquets; and provision being made for only one kind, Mr. Park was left out; but he has taken so many prizes that he can very well afford to let others have a chance.

An ornamental stand of flowers by Mr. Messelberg was one of the prettiest objects in the room. There was also a pretty ornamental design, but by whom made we do not know. Mr. Peter Henderson, of Jersey City, made a large and fine show of Verbenas, and among them some fine seedlings. Mr. Marc, of Astoria, exhibited a collection of very choice Gladioli. Collections of vegetables, and good ones, were exhibited by Messrs. Perry, Barnes, Prosser, etc. Mr. Cockerill, gardener to B. C. Townsend, Esq., exhibited the new upright Tomato, finely fruited. Mr. Cyphor, of Tarrytown, exhibited a beautiful rustic cottage, made of scales from the cone of the Norway Spruce. It was a remarkably fine piece of workmanship. Mr. Marin, an amateur, presented "a couple of hanging baskets, which for taste and workmanship would have done credit to older hands. There were also japanned flower pots and hanging baskets from Mr. Eberhardt, of New York.

Among Fruits, Messrs. Ellwanger & Barry were the largest exhibitors, their display consisting of Apples and Pears. They had 67 varieties of the former and 135 of the latter. They embraced the old kinds, and some not yet much known. The display was a fine one. The next largest collection was that of Mr. Marc, of Astoria. The specimens had been carefully selected, and were very fine. Mr. Marc has been noted as a Rose grower, but he is now making Pears a specialty) and we noticed in his collection several newly imported varieties, Beurre Mouxion being one of the best. Mr. Quin, gardener to Professor Mapes, competed successfully for the best 12 varieties of Pears. The specimens and kinds were remarkably good. Mr. Weir, of Bay Ridge, also had a choice collection of Pears. There were smaller collections from Mr. Grant, of Astoria, Mr. Tanner, of Brooklyn, Mrs. De Gray, of Bedford, and others. Peaches and Plums were shown by Mr. Tanner and Mr. Huggins, and a plate of Peaches by Miss Degrauw, of Brooklyn. The competition in Native Grapes was larger than on former occasions. Mr Brocksbank, of Hudson, and Dr. Fowler, of Fishkill, exhibited in quantity, and made a fine show.
