Bobby was very hungry, as every healthy boy the world over is sure to be when he rises in the morning, and when he had completed the ventilation of his cave to his satisfaction he proceeded to make a small fire over which to grill one of his birds, never doubting the smoke would pass out of the ventilating holes that he had made through the top of the drift. But to his chagrin the smoke did not rise and was presently so thick as to blind and choke him, and he found it necessary to put the fire out. And so it came about that in the end he had to content himself with eating his sea pigeon uncooked, which after all was no great hardship.
