204. Among the most scientific gardeners in Europe may be mentioned Professor Van Mons, of Brussels, This gentleman has given to the world more new and excellent pears than ever were before raised from seed by any individual. He also wrote on the subject of raising fruits from seeds, in the Journal d'Agriculture des Pays Bas and some other public journals, and published a separate work on fruit trees. Prof. Van Mons was the first to show the advantage of raising successive generations of the same seedling. (Jour. d'Agr. des Pays Bas, &c., Sept. 1829, p. 180.) After his death, in 1844, his nursery was carried on by Messrs. Bivor and Fossoul, nurserymen.
