"Good!" cried Jack. "Then let's give 'em a salute."
Edmund smiled and nodded his head:
"The guns are in the locker," he said.
Jack had one of the automatic rifles out in a hurry.
"Shoot high," said Edmund, "and off toward the open country. The projectiles fly far, and I guess we can take the risk."
He threw both windows open, and Jack aimed skyward and began to pull the trigger.
Bang! bang! bang! Heavens, what a noise it was! The car must have seemed a flying volcano. And it woke them up! The sleeping city poured forth its millions to gaze and wonder. Surely they had never heard such a thundering. Within five minutes we saw them on the roofs and in the towers. Many were staring at us through a kind of opera glasses which they had. Then from a dozen aerial pavilions the colors broke forth and quivered through the air.
"Saluting us!" exclaimed Jack, delighted.
"Asking one another questions, rather," said Edmund.
