We are indebted to the politeness of the officers of this Society for a complimentary ticket to attend their Summer Exhibition, which took place at Havana, N. Y., on the 20th and 21st of June. A previous engagement alone prevented us from mingling with them on this pleasant occasion. We should be obliged to their Secretary for an account of the exhibition. We notice a commendable feature in their price list, which ought to be more common, viz., a division of the competitors into amateurs and professional men. We append a list of the officers for 1860: President, Col. E. C. Frost, Havana; Vice-Presidents, Gen. R. B. Van Valkenburgh, Bath; Hon. Asher Tyler, Elmira; L. M. Rexford, Esq., Binghampton; Hon. E. S. Sweet, Owego; Cor. and Rec. Secretary, E. P. Brooks, Esq., Elmira; Treasurer, John M. Dexter, Elmira; Executive Committee, Harvey Luce, Elmira; N. Winton, Havana; D. Decker, Elmira; T. L. Baldwin, Tioga, Pa.; F. H. Baldwin, Waverly; John M. Parker, Owego; Geo. Farnham, Addison; J. M. Dexter, Elmira; A. I. Wynkoop, Chemung; 0. Spaulding, Waverly.
