As for our hero and his friend, they stood there amongst the soldiers, watching every movement and expression, and wondering vaguely what would be the end of the interview.

"I fear very much that you are right, Señor José," said the colonel at length. "The evidence is too strong, and shows without a shadow of doubt that the prisoners entered Santiago for one purpose only. It is sad that we should commence the war with an execution; but it cannot be avoided. We must protect ourselves, for if we were to allow these two lads to leave unpunished, others would be encouraged. For spying, death is the penalty. But I will not take the responsibility upon my own shoulders for an act which in my heart I consider to be harsh and unjust. Men should be treated as men; but to apply the same penalties to irresponsible, impetuous lads is cruel in the extreme. Captain Volaga, you will escort the prisoners to the cells in Morro Castle, and arrange for their refreshment. See also that blankets are given them, for the nights are getting cold. Here is a note to the officer in command. Deliver it to him personally. I will now cable to Havana and ask for instructions, but I fear that I can give no hope. Spies, whether men or boys, must meet the same fate."

He rose from his seat, and, with a wave of the hand, signified that the interview was over.

The soldiers at once closed round Hal and Gerald, and, at the officer's order, marched out of the room. Then they halted outside, while José d'Arousta and the injured captain conversed in low tones. Evidently some satisfactory arrangement was come to, for they nodded and smiled in the most pleasant manner, and when parting treated each other to an elaborate salute. Then José approached the prisoners, and, halting in front of them, addressed them in low tones which could not be overheard.

"Señores, who could have guessed that in such a short space of time the tables would turn so completely!" he said, with a triumphant smile. "But yesterday I was a prisoner in your hands, under a threat of death; and now you are in a similar condition, with this one difference: I escaped to avenge the insult, while you will live only till to-morrow's sun is up. Think of it! Dream of it! When the dawn comes, and you are led out into the cold, your end will await you. Consideration will be shown, I promise you, for some minutes shall be granted for quiet reflection. And then, Señor Marchant, if you will but raise your eyes, you will find that the ever-faithful José attends you, and will be ready, should you desire it, to carry your adieus to the fair Señora Dora. Believe me, we will weep together for your loss."

He smiled a cruel, vindictive smile, and looked hard at Hal to see what effect the words had had, but only to be disappointed. Not a muscle of the young fellow's face moved as he returned the stare of the Spaniard with one that was as proud and disdainful as it was possible to be. Then his features relaxed, and he smiled.

"The man is a bold villain," he said, with a laugh, turning to Gerald. "When we are surrounded and held by the soldiers, so that he need fear no punishment, he does his utmost to goad us into fury. Come along, old boy; we have better things to do than to listen to such a fellow."

Taking Gerald by the arm, he signified to the sergeant that he was ready, and the order being given to the soldiers, they marched out of the building, leaving José d'Arousta biting his lips with vexation.

A large crowd was waiting outside, hoping to catch sight of the first captives of the war. The news that they were spies, who had entered Santiago in search of information, had been conveyed to them, so that the appearance of the two lads was greeted with a storm of shrill cries.

"Kill them! Shoot them!" the mob shouted, rushing towards the party of soldiers who surrounded Hal and Gerald. But a line of troops drawn up outside the house interposed, and thrust them back. Then, forming up on either side, the Spaniards marched them off to the fortress which stands perched high up on one side of the long entrance to the harbor, and which goes by the name of the Morro Castle. Half an hour later the gates were reached, and they marched in, leaving the crowd outside. Hal and Gerald were led up a long flight of stone steps, through a dark corridor, and afterwards up more stairs. Finally, they came to a gallery, and were halted in front of an iron-studded door, at the keyhole of which a soldier fumbled.
