Glennie repeated Matt's words to the Chilian, and the latter's face cleared as if by magic. No doubt he thought that he and his comrades were to have their own way on the Grampus.
"He says all right, Matt," said Glennie, "but he warns us that if we try to do anything more than obey orders he will shoot. He and his comrades are determined to reach the River Plate, and are willing to give up their lives trying to do so."
"If he can take chances," said Matt grimly, "then so can we."
The Chilian gave an order to the three men with him, and the ropes were taken off the ensign's hands. The three Chilians then led him out of the room.
"Count on me to do everything that's possible, Matt," called Glennie.
When they were gone, the leader himself cut the cords that bound Matt. Presenting the revolver, he motioned sternly for Matt to rise and proceed through the door.
Matt did not intend to rebel just then. He was anxious to get the Grampus to the surface; then, after that, he and his two friends could do whatever they thought best.
The Chilians were playing a desperate game; and the fact that they were obliged to rely on their prisoners for running the boat made it all the more hazardous.
The young motorist proceeded forthwith to the engine room. Kneeling behind him, his captor continued to keep him covered with the weapon.
Presently Dick, followed by another Chilian armed with a harpoon that belonged on the boat, appeared in the tank room.
