But trade and the acquisition of wealth have not been the all-engrossing pursuits of his life. His inherent love of rural pursuits led him, in 1832, to purchase his present estate in Dorchester, originally that of Governor Increase Sumner, where, after devoting a proper time to business, he has given his leisure to horticulture and agriculture He has spared no expense, he has rested from no efforts, to instil into the public mind a love of an employment so honorable and useful. He has cultivated his own grounds, imported seeds, plants, and trees, and endeavored by his example to encourage labor and elevate the rank of the husbandman. His garden, greenhouses, and a forest of fruit-trees have occupied the time he could spare from business, and here he has prosecuted his favorite investigations, year after year, for half a century, to the present day. Soon after the Massachusetts Horticultural Society was formed, Mr. Wilder was associated with the late General Henry A.S. Dearborn, its first president, and from that time till now has been one of its most efficient members, constantly attending its meetings, taking part in its business and discussions, and contributing largely to its exhibitions. Four years since, he delivered the oration on the occasion of its semi-centennial. One of the most important acts of this society was the purchase of Mount Auburn for a cemetery and an ornamental garden. On the separation of the cemetery from the society, in 1835, through Mr. Wilder's influence committees were appointed by the two corporations, Judge Story being chairman of the cemetery committee, and Mr. Wilder of the society committee. The situation was fraught with great difficulties; but Mr. Wilder's conservative course, everywhere acknowledged, overcame them all and enabled the society to erect an elegant hall in School Street, and afterward the splendid building it now occupies in Tremont Street, the most magnificent horticultural hall in the world. It has a library which is everywhere acknowledged to be the best horticultural library anywhere. In 1840, he was chosen president, and held the office for eight successive years. During his presidency the hall in School Street was erected, and two triennial festivals were held in Faneuil Hall, which are particularly worthy of notice. The first was opened September 11, 1845, and the second on the fiftieth anniversary of his birth, September 22, 1848, when he retired from the office of president, and the society voted him a silver pitcher valued at one hundred and fifty dollars, and caused his portrait to be placed in its hall. As president of this association he headed a circular for a convention of fruit-growers, which was held in New York, October 10. 1848, when the American Pomological Society was formed. He was chosen its first president, and he still holds that office, being in his thirty-third year of service. Its biennial meetings have been held
