Then seizing the chair again, he made for the window and threw it with all his force against the panes. They crashed and the air came rushing in, reviving him enough for the second attempt. This not only smashed the pane, but loosened the shutters, and in one instant two sights burst upon his view — the face of a man in an upper window of the adjoining barn and the sudden swooping up from below of a column of deadly smoke which seemed to cut off all hope of his saving himself by the means he had calculated on. Yet no other way offered. It would be folly to try the door again. This was the only road, threatening as it looked, to possible safety for himself and her. He would take it, and if he succumbed in the effort, it should be with a final thought of her who was fast becoming an integral part of his own being.
