The captain had thrown aside his hat and was smoking a cigarette in one of the easy seats as the boys entered. He gave them only a hasty glance as he blew a cloud of smoke into the air, and the next minute he was covered by Billie's weapon.
"Up with your hands!" was the stern order.
The captain hesitated, but a sharp prick from Donald's sword sent the hands into the air.
In another minute the captain was disarmed.
"Now," said Donald sternly, "we'll see what all this trouble is about."
He opened the telegram he held in his hand and read:
"American Admiral has given an ultimatum. Hold train and passengers until further orders.
Maas."
"Who is Maas?" asked Donald sternly.
The captain shrugged his shoulders, but said nothing.
