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.

"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 contra
