Narrative

Raised in the nurseries of Baltet Brothers, Troyes, France, about 1870. Brought to America about 1885. Fruit resembles Bartlett in form and coloration but is usually larger in size. Flesh somewhat granular, reasonably juicy, buttery. Fairly sweet, sprightly flavor at the optimum stage of ripeness but quickly becomes mealy and insipid in taste. Very susceptible to core breakdown. Overly tender and too transitory in character to rate as a commercial variety. Somewhat earlier than Bartlett in season. Tree considerably more vigorous than Bartlett but definitely a shy bearer. Moderately susceptible to fire blight.
