But now the vessel was close enough for those on shore to make out her flag. The emblem flying aloft was that of the Czar. Hal drew off his coat and waved it about his head.
“If they will stop and pick us up,” he explained, “it may save us a tedious ride.”
A sharp blast of the whistle signified that Hal’s signal had been seen. The steamer came to a stop in midstream, a launch put off toward the shore, and soon grounded at the spot where the four friends stood.
Quickly they leaped into the little craft and were soon aboard the steamer, where they were greeted by the commander of the vessel. Hal explained their situation as briefly as possible.
“Well,” said the commander, “I can’t promise to put you ashore immediately, for I am bound further up the river in pursuit of a German steamer that has been bombarding several upstream towns. When I have disposed of the enemy, however, I shall be glad to land you down the stream, for I shall return immediately I have sunk the foe.”
With this the fugitives had to be content. They were assigned quarters on the steamer, and after washing the dirt and grime from their hands and faces, they returned on deck, where they made themselves comfortable as the steamer continued on her way. They passed several little towns without stopping.
Suddenly those on deck were brought to their feet by the booming of a single heavy gun. All strained their ears to listen. The first report was followed by the sound of others. The commander of the vessel sprang to action.
“Full speed ahead!” he cried.
The steamer leaped forward faster than before. The crew prepared for action. The guns were made ready and the crews stood to their posts. The commander, from his position, motioned the four friends toward him.
“We have run the enemy down,” he informed them. “Can I count upon your services if they are needed?”
