In 1825, he sought a wider field of action and removed to Boston. Here he began business under the firm name of Wilder & Payson, in Union street, then as Wilder & Smith, in North Market street, and next in his own name, at No. 3, Central wharf. In 1837 he became a partner in the commission house of Parker, Blanchard, & Wilder, Water street, next Parker, Wilder, & Parker, Pearl street, and now Parker, Wilder, & Co., Winthrop square. Mr. Wilder is the oldest commission merchant in domestic fabrics in active business in Boston. He has passed through various crises of commercial embarrassments, and yet he has never failed to meet his obligations. He was an original director in the Hamilton, now Hamilton National, Bank, and in the National Insurance Company. The latter trust he has held over forty years, and he is now in his fiftieth year in the former. He has been a director in the New England Mutual Life Insurance Company for nearly forty years, and also a director in other similar institutions. 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 a house in Dorchester originally built by Gov. Increase Sumner, where, after devoting a proper time to business, he gave his leisure to horticulture and agriculture. He spared no expense, he rested from no efforts, to instill into the public mind a love of an employment so honorable and useful. He 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, green-houses, and a forest of fruit-trees 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.
