On their way to the ticket window, Hal stopped suddenly.

"What's the matter" asked Chester.

"Matter!" exclaimed Hal. "The matter is I haven't any money. All I have was enough to send that telegram, and that amount won't get us to Brussels."

Chester reached in his pocket, and a startled expression came over his face.

"Neither have I," he exclaimed, feeling first one pocket and then another. "I have lost my pocketbook. All I have is a little change."

The lads looked at each other in silence for several minutes.

"What shall we do?" Chester asked finally.

"I don't know what to do," replied Hal; "but we have got to do something. I guess the best thing is to go back to the embassy and see if we can't raise the price of a couple of tickets. I am sure the ambassador will let us have it."

"A good idea," said Chester. "I guess the sooner we get there the better. Come on."

The ambassador received them immediately.
