Andy had a spy-glass, and with this he swept first the ocean and then the land.
On catching sight of the Japanese soldiers he was about to retire at once and sink the submarine craft, when by accident his eyes rested upon Oscar.
At first he could not believe the evidence of his senses. Then he waved his hand in recognition.
The young captain of the new Holland could not see the movement very well, but he nodded his head vigorously in the direction of the first lieutenant.
In another moment Andy disappeared and soon the Holland sank from sight. Oscar waited anxiously, wondering what his friends would do—in fact, what they could do.
The submarine craft was designed wholly for warfare on and under the ocean, not on land.
Yet Oscar knew that his friends would never desert him, now they knew he was a prisoner of the enemy.
Quarter of an hour went by. To the prisoner it seemed an age.
He was watching the water and soon saw a slight movement behind a number of bushes just where the river met the ocean.
He knew what the movement meant. The Holland XI. had come in shore as far as the depth of the water permitted.
