"Yes, señor; the house gets narrower as it nears the sea. This is by far the best lighted room on this side. No doubt the rooms on this floor were the abode of the chief who built it, and his principal followers; the others would be above."
"Well, we will light the two torches. Yes, there is no doubt that this was the room. You see there are brackets against all the pillars for holding torches. Before we go farther we will see what they are made of."
He took his knife out of his pocket and went up to one of the brackets, which consisted of bars of metal an inch and a half square and eighteen inches long. They widened out at the end, and here was a round hole about two inches in diameter, evidently intended to put the torch in. The metal was black with age. He scraped a few inches off one of them with his knife. "Silver!" he exclaimed. "It would have been better if they had been gold. But as there are four on each pillar, and twelve pillars, they would make a tidy weight. That is a good beginning, Bertie. If they are the same in all the rooms there would be several tons of it."
There was but one door to the room; through this they passed. Dias, now that there was some explanation for what he considered the work of the demons, had a more assured air. One passage led straight on; two others ran parallel to the wall of the room they had left.
"We will examine these first," Harry said. "It is likely enough they lead to the stairs to the lower room. There must be two floors below us, one above the level of the top of the tunnel, the other below that must be divided in two by it."
As they advanced into the passage there was a strange and sudden clamour, a roaring sound mingled with sharp shrieks and strange little piping squeaks. Maria ran back with a shriek of alarm, and there was a strange rush overhead. The torches were both extinguished, and Harry and his brother discharged their rifles almost at the same moment. Dias burst into a shout of laughter as they both dropped their weapons and swung their double-barrelled guns forward. "What on earth is it, Dias?"
"It is bats and birds, señor. I have seen them come out of caves that way many times. I dare say the place is full of bats. The birds would only come into rooms where there is some light."
Turning round they saw quite a cloud of bats flying out through the door.
"Confound it!" Harry said. "They have given me the worst fright I ever had in my life."
They went back to the room, they had left. Both Harry and Bertie had lost every tinge of colour from their faces.
