Prince, William

The name of Prince is identified with American horticulture. Perhaps no man has done more to gratify the taste of amateurs of flowers and fruit than the late William Prince, whose extensive grounds at Flushing, New York, were the nursery of almost every vegetable calculated to please the eye or palate. We regret that there is not within our reach the data from which to draft a particular description of the foundation, rise and progress of the "Linnaean Botanic Garden".
