Narrative

Introduced in 1905 by the noted French pomologist Charles Baltet, Troyes, France. The core is remarkably small, and the seeds are few and small. The tree is robust and generally satisfactory. In Europe the variety was heralded as a most remarkable sort 'destined to bring about a revolution in pear-growing.' It may be worth further trial in this country.
