They came now along a high, open fence that ran the entire length of a square. Above it a dense rank of bitter orange-trees overhung the sidewalk, their dark mass of foliage glittering in the moonlight. Within lay a deep, old-fashioned garden. Its white shell-walks gleamed in many directions. A sweet breath came from its parterres of mingled hyacinths and jonquils that hid themselves every moment in black shadows of lagustrums and laurestines. Here, in severe order, a pair of palms, prim as mediaeval queens, stood over against each other; and in the midst of the garden, rising high against the sky, appeared the pillared veranda and immense, four-sided roof of an old French colonial villa, as it stands unchanged to-day. The two loiterers slackened their pace to admire the scene. There was much light shining from the house. Mary could hear voices, and, in a moment, words. The host was speeding his parting guests. "The omnibus will put you out only one block from the hotel," some one said. * * * Dr. Sevier, returning home from a visit to a friend in Polymnia street, had scarcely got well seated in the omnibus before he witnessed from its window a singular dumb show. He had handed his money up to the driver as they crossed Euterpe street, had received the change and deposited his fare as they passed Terpsichore, and was just sitting down when the only other passenger in the vehicle said, half-rising:-- "Hello! there's going to be a shooting scrape!" A rather elderly man and woman on the sidewalk, both of them extremely well dressed, and seemingly on the eve of hailing the omnibus, suddenly transferred their attention to a younger couple a few steps from them, who appeared to have met them entirely by accident. The elderly lady threw out her arms toward the younger man with an expression on her face of intensest mental suffering. She seemed to cry out; but the deafening rattle of the omnibus, as it approached them, intercepted the sound. All four of the persons seemed, in various ways, to experience the most violent feelings. The young man more than once moved as if about to start forward, yet did not advance; his companion, a small, very shapely woman, clung to him excitedly and pleadingly. The older man shook a stout cane at the younger, talking furiously as he did so. He held the elderly lady to him with his arm thrown about her, while she now cast her hands upward, now covered her face with them, now wrung them, clasped them, or extended one of them in seeming accusation against the younger person of her own sex. In a moment the omnibus was opposite the group. The Doctor laid his hand on his fellow-passenger's arm. "Don't get out. There will be no shooting."
