The motion of the ship by this time was so violent as to make them feel quite seasick. She swayed from side to side and now and then took long dips.
"I know what they are doing," exclaimed Frank as the ship executed the latest of these diving maneuvers; "they are setting their aeroplanes low so as to try and find a smooth current of air."

"You had better come out of there," he said briefly, "we are in a bad storm."
"Are we in danger?" asked Harry.
