The bal champetre was gay and brilliant, as such festal scenes are at Paris. A lovely night in the midst of May, lamps below and stars above; the society mixed, of course. Evidently, when Graham has singled out Frederic Lemercier from all his acquaintances at Paris to conjoin with the official aid of M. Renard in search of the mysterious lady, he had conjectured the probability that she might be found in the Bohemian world so familiar to Frederic; if not as an inhabitant, at least as an explorer. Bohemia was largely represented at the bal champetre, but not without a fair sprinkling of what we call the “respectable classes,” especially English and Americans, who brought their wives there to take care of them. Frenchmen, not needing such care, prudently left their wives at home. Among the Frenchmen of station were the Comte de Passy and the Vicomte de Breze. On first entering the gardens, Graham’s eye was attracted and dazzled by a brilliant form. It was standing under a festoon of flowers extended from tree to tree, and a gas jet opposite shone full upon the face,--the face of a girl in all the freshness of youth. If the freshness owed anything to art, the art was so well disguised that it seemed nature. The beauty of the countenance was Hebe-like, joyous, and radiant; and yet one could not look at the girl without a sentiment of deep mournfulness. She was surrounded by a group of young men, and the ring of her laugh jarred upon Graham’s ear. He pressed Frederic’s arm, and directing his attention to the girl, asked who she was. “Who? Don’t you know? That is Julie Caumartin. A little while ago her equipage was the most admired in the Bois, and great ladies condescended to copy her dress or her coiffure; but she has lost her splendour, and dismissed the rich admirer who supplied the fuel for its blaze, since she fell in love with Gustave Rameau. Doubtless she is expecting him to-night. You ought to know her; shall I present you?” “No,” answered Graham, with a compassionate expression in his manly face. “So young; seemingly so gay. How I pity her!” “What! for throwing herself away on Rameau? True. There is a great deal of good in that girl’s nature, if she had been properly trained. Rameau wrote a pretty poem on her which turned her head and won her heart, in which she is styled the ‘Ondine of Paris,’--a nymph-like type of Paris itself.” “Vanishing type, like her namesake; born of the spray, and vanishing soon into the deep,” said Graham. “Pray go and look for the Duval; you will find me seated yonder.” Graham passed into a retired alley, and threw himself on a solitary bench, while Lemercier went in search of Madame Duval. In a few minutes the Frenchman reappeared. By his side was a lady well dressed, and as she passed under the lamps Graham perceived that, though of a certain age, she was undeniably handsome. His heart beat more quickly. Surely this was the Louise Duval he sought.
