The New York Horticultural Society (see advertising pages) announce their fall exhibition on the 20th, 21st, and 22d of September - the same days, unfortunately, on which the N. Y. State Fair is held at Saratoga. The Society is making great efforts to get up a creditable show, and we trust will be successful. They say that their premium list is liberal, but on looking it over, we can see little worthy of being called liberal for a metropolitan show. Neither do we think the premiums well proportioned. The same premiums are awarded for Savoy cabbages, and cauliflower, and brocoli. $10 is offered for the best four hot-house plants in bloom, and only $5 for the best collection of coniferae. For the best twelve roses, just the same as the best twelve verbenas, phloxes, or antirrhinums, and the same for the two best pumpkins as for the best general display of vegetables. The premiums on foreign grapes are somewhat liberal, amounting to between $50 and $60.

The New York State Agricultural Society holds its annual show at Saratoga, on the 20th, 21st, and 22d of September. The grounds and arrangements are said to be more complete and convenient than they have ever been before, and we have no doubt the show will be a good one.
