"Our instructions," Jack continued, "are to stay here pending further orders."

"Maybe we'll get them soon," said Frank.

"Yes; and maybe we won't."

"Then we'll just have to sit tight."

"That's what worries me."

There was a knock at the door.

"Come in," Frank called.

A bell boy entered with a second cablegram.

Jack tore it open hastily.

"Hurray!" he cried.
