“Never mind about him,” they said. “The only medicine he carries is for snakebites. He flies back and forth between Canada and points along the shore hereabout. Just what he carries we don’t know for sure, but we can all guess. He’ll go right on over to Canada.” Relieved, Jimmy hopped off, headed straight out over the frozen lake toward the first island, and opened his throttle. He did not like the looks of the rough ice beneath him, and he meant to reach the island as speedily as possible. Soon he saw that he was flying faster than the bootlegger ahead of him. But as he had only a few miles to go, he thought he should hardly overtake the man. On they flew, Jimmy following straight after the other plane, and all the time creeping up on it. To fly to the island took less than ten minutes. Yet Jimmy was glad enough when he neared the shore, for he did not like the looks of the rough pack ice beneath him. He had just started to circle over the island, in order to search out a landing place, when he noticed the bootlegger’s plane acting crazily. Jimmy saw at once that something was wrong with the craft. Also, he saw that the pilot, who was already at the farther end of the island, was making a desperate effort to turn and effect a landing. The ship came down fast, landing on ground that was none too smooth, but was apparently not harmed, though the running gear might have been broken. About that, Jimmy could not be sure without a close inspection. Sweeping completely around the island, Jimmy saw that there was no better place to land than the open space in which the bootlegger had been forced down. So he came down cautiously, in as easy a glide as he could make, ready to give her the gun instantly, should the place prove impossible. But he found a long, fairly smooth stretch before him, and set his ship down neatly in the snow. She slid for some distance, then came to rest in perfect safety. Jimmy hopped from his plane and looked about him. On one side was the other flying machine, and the pilot of it was walking toward him with great speed. On the other hand, at a considerable distance, was a little group of houses, doubtless the residences of the stricken islanders. But they were evidently not all stricken, for several men could be seen coming toward him. For a moment Jimmy stood looking at them, trying to count them. He was curious about these isolated islanders, and not a little sympathetic toward them. He wondered what sort of people they would prove to be. And he was eager to get their story, and to deliver the medicines. He was also curious to know what manner of man the bootlegger would prove to be. And presently, hearing the latter’s step at hand, he spun about to face him, and found himself looking into the barrel of a revolver that the approaching bootlegger had leveled at him.
