"How?"

"Captain Espejo will certainly send a train in pursuit, Excellency. Even now I doubt not the engine is getting up steam. The hydroplane cannot go fast in the dark. The train will be first at the junction. We shall be rescued."

"That will be Captain Espejo's service, not yours."

"But we shall be taken on board the hydroplane, Excellency. The painter is broken; they cannot tow us, or if they can, they will not wish so to check their speed. Suppose I am able to damage the engine, Excellency?" he whispered, so that Azito could not hear him. "Then their chance of outstripping the train is gone."

"Could you do it?"

"I could try, Excellency. Such engines are very delicate; a trifle puts them out of order; and we shall have several hours."

"Do it, Señor Machado," whispered the General eagerly; "and when I make myself President you shall be--yes, you shall be my postmaster-general. Say no more: the Englishman has stopped talking."

Hydroplane and yacht drifted down on the slow current through the darkness. Now and then one or the other would run aground, which caused delay, but no danger, the speed being so low. None of the party knew what hour of the night it was when they came into the tributary, the scene of Will's first meeting with Azito. It was, in fact, nearly two o'clock--time to transfer the prisoner to the hydroplane and increase the speed. Ruggles threw out the little anchor, to allow the yacht to draw alongside.

"There are six of us. We can never all squeeze into the hydroplane," he said, when Will was only a foot or two away. "General Carabaño will take room for two."

"I'm afraid you're right," replied Will. "We shall have to make a hawser out of the halyards, and tow as before. It will put more work on the engine, but I think it can stand it, and if we can get to the narrows safely we shall be all right."
