"Well, you've made a big mistake," Mr. Pertell went on. "Mistake! Ha! I guess not!" cried the officer. "We don't make mistakes up here! One of my men seen something queer goin' on out in the river, and come and told me. Then I seen your boats puttin' off, and I knew something was wrong. So I got my forces together, and we waited for these fellows. We've got 'em, too! Every one of 'em!" he added proudly. "Lock 'em up, men!" he ordered. "We'll show these fellows what Jersey justice is like. Take 'em away." "Hold on!" cried Mr. Pertell, and this time he allowed a smile to show on his hitherto glum face. "You don't seem to understand." "Oh, I think I do," said the police officer calmly. "I understand a great deal more than you think I do. Come on." "Wait! I'll explain!" cried the manager. "It's for the moving pictures!" he added. "This is only a pretended attack and pursuit. Ask the young ladies themselves," he said, motioning to Ruth and Alice who were now smiling. Certainly they did not seem to be in any great alarm or distress over their recent adventure. Their appearance must have caused the officer to doubt the wisdom of his course. "Weren't these fellers chasing you?" he demanded, motioning to the prisoners. "Now don't say they wasn't, for I saw 'em." "Oh, yes, they were pursuing us," admitted Ruth, "but it was all in the picture." "The picture?" questioned the officer. "Yes. We are moving picture actresses and actors," she went on, and her father, coming up then, though he had had no active part in the chase, confirmed what she said. For a moment the police captain maintained a silence, and then, as he could no longer doubt what was said, since Mr. Pertell exhibited certain credentials, the representative of Jersey justice said: "Well, this certainly is one on me! We'd better go back, boys," he added to his men, "and we'd better keep quiet about this thing. But I sure thought this was a kidnapping case." "And you spoiled my picture," groaned Mr. Pertell. "Now we've got to go back to the middle of the river, and do it over from there." "Hold on a minute!" exclaimed Pop Snooks, who, as property man, was also a sort of assistant manager. "Maybe this will turn out all right after all." "How do you mean?" asked Mr. Pertell. "Why, the police. We could have them try to stop the pursuers but get worsted in the encounter, and the roughs could keep right on after the girls. In that way we won't have to waste much film. Just go on with the picture from the point where these policemen came in." Mr. Pertell thought for a minute. "That's the idea!" he suddenly cried. "It will make a better picture that way. Say!" he went on to the police officers: "You're in on this!" "In on what?" asked the captain. "On this scene. I can use you and your men. You won't mind a little rough and tumble work, will you?" "What do you mean?"
