Sinclair and I looked on. The spirits of Elinor were exuberant. She laboured as it seemed, under more than ordinary excitement. She laughed and chatted with her tawny partner with a delight which it was impossible for such a copper monster to create. The gaiety of the lady had but one effect upon her partner. At short intervals he opened his jaws and exhibited his teeth to the company. Having rivalled a hyena in the hideousness of his grin, he closed the jaws and hid his molars. Far different was the effect upon another. It took but a very little time to discover that Rupert Sinclair had not been proof against the charms of this darling of nature. His heart had felt her witchery, and his spirit was enchained--not utterly and irretrievably, I fondly trusted, for I knew his worth, and could not willingly entrust him to such doubtful keeping. Elinor Travis was not the wife for Rupert Sinclair. Thanks to the Yahoo, my fears at first were not alarming; still it was vexatious enough to behold the pain with which Sinclair evidently regarded the good fortune of the Indian, and the complacency with which the monster received the favour of one of the loveliest of her sex. Once during the dance, the change of the figure brought the lady within a few feet of Sinclair. Her back was towards him, but, as if aware of his vicinity, she turned round and cast the lustre of her full eye upon him. She smiled, and archly nodded. Rupert shook like a leaf; the colour mounted to his cheek, and his heart beat almost audibly. I grew alarmed. My faith in the Yahoo was shaken, and I trembled for my friend. The position of the dancers was again reversed. Elinor faced us. Her eye once more was fixed upon Rupert, but this time, as I believed, exulting in triumph. Could it be possible that she was aware of her influence, and that she inhumanly trifled with this man's affection? What meant that ardent gaze and that triumphant smile? As the general had informed us, so it happened. The Yahoo danced four quadrilles with Elinor, and then vouchsafed the loan of his blackness to other ladies for the rest of the evening. Miss Travis being at liberty, I proposed to Rupert an adjournment to our hotel. The gentleman, in answer, started up and secured the hand of Elinor for the next dance. His chair at my side was filled on the instant by the general himself. I listened and replied to the questions of the latter as well as I could, watching every movement, step, and gesture of the young sorcerer and her victim.
