"I'll unlock this gate for you, and you can wheel her out," said the officer, who seemed to know something about aircraft. He rode over to a double gate, which he soon swung open, and Dick and his chums, by considerable exertion, managed to wheel the airship out on the walk. The slope of the buffalo enclosure was downward or they might not have been successful. "Now then," went on the mounted policeman, when he had locked the gate to prevent any of the animals from straying out, "who's in charge of this outfit?" "I am," admitted Dick, as his chums looked at him. "Well then, I'm sorry, but I have to place you under arrest," spoke the officer. "You'll have to come with me." "Arrest! What for?" gasped Dick. "Two charges. Entering the buffalo enclosure without a permit, and flying an airship over a city. I saw you come from down New York way." For a moment those of Dick's aviation party hardly knew whether to treat the matter as a joke or not, but a look at the face of the officer soon convinced them that he, at least, was in earnest. "Under arrest!" murmured Dick. "Well, I guess the two charges are true, as far as that goes. We did fly over the city, but there was no harm in that, and--" "Hold on--yes, there was!" exclaimed Mr. Vardon. "It was stupid of me to forget it, too. It is against the law now for an aeroplane to fly over a city, and contrary to the agreement of the association of aviators." "You are right!" exclaimed Lieutenant McBride. "I should have thought of that, too, but I was so interested watching the working of the machinery I forgot all about it. The rule and the law was made because of the danger to persons over whose heads the aeroplanes might fly--that is, not so much danger in the flying as in the corning down. And then, too, as a general thing it might not be safe for the aviators if they were forced to make a landing. But we've gone and done it, I guess," and he smiled frankly at the officer. "As for coming down in the buffalo enclosure, I was sorry we did it when I saw that old bull coming for us," remarked Dick. "But it seemed the best place around here for us to land, after our motor stopped. I suppose it won't do any good to say we're sorry; will it?" he asked the policeman, with a smile. "Well, I shall have to do my duty, and arrest you," said the officer, "but I will explain to the magistrate that you did not mean to land contrary to the law." "Who is the magistrate before whom we shall have to appear?" asked Larry Dexter. "Judge Scatterwaite," was the answer. "Good!" cried the young reporter. "I know him. My paper supported him in the last campaign, and I believe he will be glad to do a favor for me. Is there a telephone around here?" he asked the officer. "Oh, we won't run away," he hastened to assure the guardian of the peace. "I just want to talk to the judge. I'm Larry Dexter, of the Leader."
