When Paul turned around, after being on the chase for a little time, and saw Russ coming toward him, he stopped to allow the young moving picture operator to come up to him. For he saw that the pursuit was to be a long one, and the man had such a start of him that a few seconds' delay would make no difference. On and on over the fields went the stranger, until he was headed down a highway. "When he gets on that it will be easier going," remarked Russ. "Yes, for both of us," agreed Paul. "I wonder what in the world his game can be, anyhow?" "We'll find out--if we ever get him," panted Russ. "Come on! This is going to be 'some run,' as the poets say." The man gained the highway, and raced along that for some distance. Paul and Russ tried to take a short cut across the field to reach the same road, but they got into a marshy place and sank in, nearly up to their knees. "He knew this was here!" cried Russ, as he drew himself out of a sticky place. "He evidently did, and avoided it," agreed his friend. "And we blundered into it--worse luck!" They had considerable difficulty in reaching the road, and by that time the mysterious man was even further in advance. But they pluckily kept to the chase. "There he is!" cried Russ, as they came to a turn in the road, and saw a straight stretch before them. "He hasn't gained so very much." The man was running well, and there seemed to be no return of his lameness. The neighborhood was a lonely one, and there were no houses in sight. Nor had the young men engaged in the chase met any persons since starting out. Doggedly they kept on. "This would make a good picture film!" exclaimed Russ. "It sure would," agreed Paul. "Only we haven't time to do it. Say, he can run some; can't he?" "He sure can. Oh, look at that, would you!" cried Russ. They had now come in sight of a white house, standing back a little from the road. And in front of the house stood an automobile runabout. What caused Russ to cry out was the sight of the mysterious man leaping into the auto, the engine of which had evidently been left running. In another moment he was off down the road, going at the limit of speed of the machine. "Well, we might as well give up now," said Paul, coming to a stop. "I'm done up, anyhow." "Same here," agreed Russ. "That is, unless we can find another auto." They saw a man run from the farmhouse from in front of which the auto had been so audaciously taken. He was a physician, it appeared. "The idea! The idea!" he cried. "That perfect stranger ran up and took my auto. Was he a friend of yours?" he asked as Russ and Paul came up. He looked at them suspiciously. "A friend! No indeed!" exclaimed Paul. "We want to catch him; but we can't do it now." They heard the sound of hoofbeats in the road behind them, and, turning, they saw Sandy coming along on the farm horse. He had taken a short cut, guessing or hoping that the chase would lead that way.
