This young Society recently held its first public exhibition at St. Paul, and they seem to have had a good time. The secretary, Mr. Hewson, sends us the following account of it:

The Horticultural Exhibition was far more extensive and beautiful than could be expected, and gave rich promise of the future. Strangers and citizens were squally surprised and delighted at the magnificence of the floral display, as well as the fine specimens of our fruits and vegetables.

The Balsams, Delphiniums, Fuchsias, Pelargoniums, Geraniums, Petunias, Phloxes, Pinks, Pansies, and Verbenas were much admired. The exhibition of Cut Flowers, Greenhouse Plants, Wild Flowers, and Roses was also very fine.

The strawberries exhibited by W. H. J arvis, M. D. Clark, and Dr. A. E. Ames, of the Wilson's Albany, McAvoy, and Hovey's Seedling, were too tempting and luscious to remain untasted during the day. We have often seen larger specimens, but none of more exquisite flavor. The red, white, and black currants exhibited by Alx. Buchanan, T. M. Smith, and W. H. Jarvis, respectively, were excellent; the gooseberries, by W. H. Jarvis and J. W. Selby, were the largest we ever saw. There were also fine specimens of red and black raspberries, by Mrs. H. L. Moss. Mr. P. W. Nichols exhibited a limb thickly hung with Siberian Crab Apples.

In vegetables, the rhubarb exhibited by Mr. M. D. Clark had the largest stalks, and took the first premium. The specimens by M. H. Jarvis, J. W. Selby, and T. M. Smith, were not far behind, and so nearly equal, that the Committee could not agree as to which was entitled to the second premium. The cucumbers by Mr. Clark and Mr. Mitchell (gardener for Judge Nelson) took the first and second premiums. Mrs. C. W. Borup took the first premium on tomatoes. There was also an excellent show of lettuce, radishes, cabbages, "kohl rabi," peas, beets, cauliflowers, carrots, turnips, beans, onions, corn, dtc. The following is a list of the premiums awarded:
