"I have seen as large, or larger, at Bombay and some of the towns on the coast."

"They bite people's toes when they are asleep, don't they?"

"Yes, the great vampire bat does, but I have never heard of any others doing so. They live on insects, and some of them are, I believe, vegetarian."

"Are vampire bats found here?"

"I do not think so; I fancy that they inhabit Java and other islands in the Malay Archipelago. However, they are certainly rare, wherever they come from, and you can dismiss them altogether from your mind."

"I was glad when I heard your voices, señors," Maria said when she appeared a quarter of an hour later. "I knew they would not hurt me; but I was horribly frightened, and wrapped myself up in my blanket and lay there till I heard you talking, and I heard the logs thrown on the fire; then I felt that it was all right."

"I don't suppose they will come again, Maria."

After drinking a cup of coffee, with a small piece of maize cake, Bertie said:

"What is the programme for to-day?"

"We can't do much till Dias comes back. We may as well go down and have a look at the lower rooms. I don't think there is much dust on the floor there, but while José is away looking after the mules we will cut enough bushes to make a couple of brooms. We shall want the place swept as clean as possible, so that we can look about, but I don't think there is the least chance of our being able to move the stones. Before we do anything we will go down to the pool and have a swim, and dive out through the entrance and have a look at those rocks."
