"So they will; I did not think of that. But when they once find that they cannot get out here in the evening, they will go out where they came in, and we shall have no more trouble with them. I don't know whether they are good to eat?"

Maria gave a little cry of horror.

"Oh, señor! I could not eat such horrible things!"

"Their appearance is against them, Maria; but when people eat alligators, frogs, snakes, and even rats, I don't see why a bat should be bad. However, we won't touch them unless we are threatened by starvation."

"I should indeed be starving before I could touch bats' flesh, señor."

"Well," Harry said, "if people eat monkeys, rats, and squirrels—and it seems to me that a bat is something of a mixture of the three—one might certainly eat bats, and if we are driven to it I should not mind trying; but I promise you that I won't ask you to cook them."

They chatted for another hour, and then Maria went off to her corner. The brothers spread their beds by the fire, and José had his blanket and poncho, and it was arranged that any of them who woke should put fresh logs on the fire.

They were all roused just before dawn by a squeaking and twittering noise. They threw on fresh logs, and as these blazed up they could see a cloud of bats flying overhead. They kept on going to the doorway, and when they found they could not get through they retired with angry squeaks. The light was gradually breaking, and in a few minutes all had flown out through the opening. Harry and his brother followed them, and could see them flitting about the upper windows. Presently, as if by a common impulse, they poured in through the various openings.

"I don't suppose we shall see any more of them," Harry said, "and I own that I shall be glad. There is something very weird in their noiseless flitting about, and in the shadows the fire casts on the ceiling."

"They are a great deal larger than any bats I have seen," Bertie said.
