Narrative

Napoleon. One of the new Flemish pears; the size is large, the form long, round at the blossom end, contracted in the middle, obtuse at the stem, which is short; the skin at maturity is a yellowish green; flesh melting and fine, with an unusual quantity of juice; in some soils, a little too astringent; tree healthy and strong, bears well, and the fruit ripens in October. [This tree has borne with us fine melting pears, without astringency, for two years past. Bears greatly on small trees.] -- R. Manning, The New England Fruit Book, 1844.
