"From inquiries, sir, I find he did not stay with the others, but went around town by himself. Some sailors were talking with him in front of the hotel, and they state that he started off for the fort. After he had gone some distance they also decided to visit the fort and followed him, but when they came to the road that leads up the hill they saw him still going along the main road in an easterly direction. They thought he acted queerly in not asking them to accompany him, for they were discussing the matter between them, and when they saw he didn’t go towards the fort at all, they decided he must have some reason for not wanting them along. That was the last seen of the boy." "Thank you, Sergeant, that is all. Let me know if you hear anything further." "Aye, aye, sir," and Sergeant Douglass saluted and turned away. "It’s after six o’clock, sir, and if that is all for the present I will get ready for mess." Captain Bentley was about to reply when the Gunner came hurriedly up the ladder and, spying Lieutenant Commander Ogden, he approached and saluted. "Mr. Ogden, the chief gunner’s mate reports to me that two Colt’s forty-fives, and a dozen boxes of ammunition have disappeared from the armory since morning quarters. He put the revolvers away himself and locked the door--it is a snap lock--which was still as he left it when he went in the armory a while ago." "Who has access to the armory, Mr. Nelson?" asked the Captain, and a dark frown appeared on his face. Too many inexplicable things were happening on board his ship this day to suit him, and he was becoming decidedly annoyed. "I have the only key, sir, and I never allow anyone in the armory except the chief gunner’s mate. Whenever he gets through his work there he always brings the key to me. Of course, Mr. Ogden has duplicate keys, as you know, sir." "Does the chief gunner’s mate permit anyone in there?" "No, sir, I believe he obeys my order to the letter. A few days ago he asked and received permission to allow Drummer Comstock of the marines in there. The boy wanted to familiarize himself with the mechanism of the Colt’s machine-gun." "Hm-m-m-m! What do you think now, Mr. Ogden?" and Captain Bentley gazed scowlingly at the darkening shadows on the mountainside, and the lights appearing, one by one, in the houses ashore. Even while he looked there came distinctly to his ears the loud: Sh-h-h-s-h-h! like escaping steam as from the vicinity of the consulate a streak of fire shot into the air. Then came the sound of an explosion, while directly over the ship three green balls of fire cast a ghostly glare on the upturned faces of officers and men. Señor Perez had called for aid!
