The first commercial nursery in America, in the sense of the term as we now employ it, was established about 1730 by Robert Prince, in Flushing, Long Island, a community chiefly of French Huguenot settlers, who brought to the new world many French fruits by seed and cuttings, and also a love of horticulture. For over a century and a quarter these Prince Nurseries were the leading ones in America. The sale of fruit trees was increased in 1774 (as we learn from advertisements in the _New York Mercury_ of that year), by the sale of "Carolina Magnolia flower trees, the most beautiful trees that grow in America, and 50 large Catalpa flower trees; they are nine feet high to the under part of the top and thick as one's leg," also other flowering trees and shrubs. The fine house built on the nursery grounds by William Prince suffered little during the Revolution. It was occupied by Washington and afterwards house and nursery were preserved from depredations by a guard placed by General Howe when the British took possession of Flushing. Of course, domestic nursery business waned in time of war; but an excellent demand for American shrubs and trees sprung up among the officers of the British army, to send home to gardens in England and Germany. Many an English garden still has ancient plants and trees from the Prince Nurseries. The "Linnaean Botanic Garden and Nurseries" and the "Old American Nursery" thrived once more at the close of the war, and William Prince the second entered in charge; one of his earliest ventures of importance was the introduction of Lombardy Poplars. In 1798 he advertises ten thousand trees, ten to seventeen feet in height. These became the most popular tree in America, the emblem of democracy--and a warmly hated tree as well. The eighty acres of nursery grounds were a centre of botanic and horticultural interest for the entire country; every tree, shrub, vine, and plant known to England and America was eagerly sought for; here the important botanical treasures of Lewis and Clark found a home. William Prince wrote several notable horticultural treatises; and even his trade catalogues were prized. He established the first steamboats between Flushing and New York, built roads and bridges on Long Island, and was a public-spirited, generous citizen as well as a man of science. His son, William Robert Prince, who died in 1869, was the last to keep up the nurseries, which he did as a scientific rather than a commercial establishment. He botanized the entire length of the Atlantic States with Dr. Torrey, and sought for collections of trees and wild flowers in California with the same eagerness that others there sought gold. He was a devoted promoter of the native silk industry, having vast plantations of Mulberries in many cities; for one at Norfolk, Virginia, he was offered $100,000. It is a curious fact that the interest in Mulberry culture and the practice of its cultivation was
