As I stood there, gripping the rail, half fearful lest we strike, the furnace doors below were suddenly flung open for a fresh feeding of the fire, and the red glare of the fire lit up the scene. Close in against the shore nestled a flatboat, evidently tied up for the night, and I had a swift glimpse as we shot by of a startled man waving his arms, and behind him a wildly barking dog. An instant more and the vision had vanished as quickly as it had appeared; even the dog's sharp bark dying away in the distance. The furnace doors banged shut, and all was again darkness and silence. I turned back along the deserted deck, only pausing a moment to glance carelessly in through the front windows of the main cabin. The forward portion was wrapped in darkness, and unoccupied, but beyond, toward the rear of the long salon, a considerable group of men were gathered closely about a small table, above which a swinging lamp burned brightly, the rays of light illuminating the various faces. I recognized several, and they were apparently a deeply interested group, for, even at that distance, I could plainly note the excitement stamped upon their countenances, and the nervousness with which they moved about seeking clearer view. There were so many closely wedged together as to obstruct my vision of what was occurring, yet I felt no doubt but that they watched a game of cards; a desperate struggle of chance, involving no small sum to account for such intense feeling on the part of mere onlookers. Gambling was no novelty on the great river in those days, gambling for high stakes, and surely no ordinary game, involving a small sum, would ever arouse the depth of interest displayed by these men. Some instinct told me that the chief players would be Kirby and Beaucaire, and, with quickening pulse, I opened the cabin door and entered.
