The boys reloaded their revolvers, watching the enemy narrowly.
"I wonder if they have enough," said Dick as he bound a handkerchief around a slight flesh wound in his left arm.
"I don't think so," answered Bert, "their blood is up and they know how few we are as compared with themselves. They certainly fought like wildcats."
"They're live wires sure enough," agreed Tom. "They--why Bert, what's the matter?" he exclaimed as Bert sprang to his feet excitedly.
But Bert had rushed to the captain and was eagerly laying before him the plan that Tom's words had unwittingly suggested.
The captain listened intently and an immense relief spread over his features. He issued his orders promptly. Great coils of heavy wire were brought from the storeroom and under Bert's supervision were wound in parallel rows about the stern of the ship. At first sight it looked as though they were inviting the pirates to grasp them and thus easily reach the deck. It seemed like committing suicide. The work was carried on with feverish energy and by the time the pirates swung their boats around and again headed for the ship, there was a treble row of wires about a foot apart on both the port and starboard side.
The revolvers had all been reloaded and every man stood ready. But the tenseness of a few minutes before was lacking. For the first time since the fight began Captain Manning smiled contentedly.
"Don't fire, men, unless I give the word. Stand well back from the rail and wait for orders."
On came the pirates yelling exultantly. The silence of the defenders was so strange and unnatural that it might well have daunted a more imaginative or less determined foe. Not a shot was fired, not a man stirred. They might have been dream men on a dream ship for any sign of life and movement. The crowded junks bore down on either side of the ship, and as though with a single movement, a score of pirates leaped at the rails and grasped the wires to pull themselves aboard.
Then a wonderful thing happened. From below came the buzz of the great dynamo and through the wires surged the tremendous power of the electric current. It was appalling, overwhelming, irresistible. It killed as lightning kills. There was not even time for a cry. They hung there for one awful moment with limbs twisted and contorted, while an odor of burning flesh filled the air. Then they dropped into the sea. Their comrades petrified with horror saw them fall and then with frantic shrieks bent to the sweeps and fled for their lives.
