"Grab 'em! Tie 'em up!" cried Tom, for they had no weapons with which to make an attack.

But none were needed. So stunned were the foreigners by the lightning bolt, which had miraculously passed our friends, and so unnerved by the striking down of La Foy, their leader, that they seemed like men half asleep. Before they could offer any resistance they were bound with the same ropes that had held our friends in bondage. That is, all but the big Frenchman himself. He seemed beyond the need of binding.

Mound, the engineer, and his assistant, came hurrying in from the motor-room, followed by Koku.

"We found him chained up," Jerry explained, as the big giant, freed from his captivity, rubbed his chafed wrists.

"Are there any of the foreigners back there?'

"Only those two knocked out by the lightning," the engineer explained. "We've made them secure. I see you've got things here in shape."

"Yes," replied Tom. "And now to see where we are, and to get back home. Whew! But this has been a time! Koku, what happened to you?"

"They no let anything happen. I be in chains all the while," the giant answered. "Jump on me before I can do anything!"

"Well, you're out, now, and I think we'll have you stand guard over these men. The tables are turned, Koku."

The bound ones were carried to the same prison whence our friends had escaped, but their bonds were not taken off, and Koku was put in the place with them. By this time La Foy and the two other stricken men showed signs of returning life. They had only been stunned.
