Where had Madame Valmonde found Desiree for the first time when she was a baby?

Monsieur Valmonde found her lying alseep as an infant near the stone pillar.

Why, it seemed but yesterday that Désirée was little more than a baby herself; when Monsieur in riding through the gateway of Valmondé had found her lying asleep in the shadow of the big stone pillar.
