None of the bullets was intended to hit the buffalo, and none did. But some came so close, and the noise of the shots was so loud, that the beast stopped suddenly, and then, after a pause, in which he snorted, and pawed the ground, he retreated, to stand in front of the herd of cows and other bulls, probably thinking he constituted himself their protector against the strange and terrible foe.

"Well, that's over!" exclaimed Dick, with a sigh of relief. "Say, isn't this the limit? If we bad an airship out on the plains fifty years ago it wouldn't have been any surprise to be charged by a buffalo. But here in New York—well, it is just about the extreme edge, to my way of thinking!"

"All's well that ends well," quoted Innis. "Now let's get breakfast."

But it seemed that something else was to come first.

"Get your craft out of there," ordered the police officer, who had fired the shots.

"I guess we'd better," said Dick to his chums. "That buffalo might change his mind, and come at us again."

"How are we going to get out?" asked Mr. Vardon, as he noticed the heavy fence around the buffalo enclosure. And there was hardly room inside it to get the necessary start to raise the big airship.

"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.
