"Quick, get under that table! I hear some one coming," warned Stubby.
Billy dodged under the table in the dining saloon while Stubby hid under a chair and Button ran up a curtain and settled himself on the curtain pole near the ceiling. The person they had heard coming soon passed through the room, and they came out of their hiding places and continued their explorations.
Presently they found it difficult to stand on their feet, and looking from a window they discovered they were slowly rising from the ground. At the same time they found it was exceedingly hard to stand still and keep their balance. Before it should grow any worse, they ran back and hid where they had before, to await further developments.
"I hope if they find us they don't pitch us overboard when they get up two or three thousand feet," said Stubby.
