What did Armand put on the bonfire?

From the text:

A graceful cradle of willow, with all its dainty furbishings, was laid upon the pyre, which had already been fed with the richness of a priceless layette . Then there were silk gowns, and velvet and satin ones added to these; laces, too, and embroideries; bonnets and gloves; for the corbeille had been of rare quality.

The last thing to go was a tiny bundle of letters; innocent little scribblings that Désirée had sent to him during the days of their espousal. There was the remnant of one back in the drawer from which he took them. But it was not Désirée’s; it was part of an old letter from his mother to his father. He read it. She was thanking God for the blessing of her husband’s love:—

“But, above all,” she wrote, “night and day, I thank the good God for having so arranged our lives that our dear Armand will never know that his mother, who adores him, belongs to the race that is cursed with the brand of slavery.”
