He caught up his camera tripod which was near his cot, and made a swing with it at the creature that had flown into the tent through an opening it had made for itself.
"Look out!" yelled Ned. "If it's a vampire it'll——"
"It won't do anything to me!" shouted Tom, as he struck the creature, knocking it into the corner of the tent with a thud that told it must be completely stunned, if not killed. "But what's it all about, anyhow?" Tom asked. "What's the row?"
From without the tent came the Indian cries of:
"Oshtoo! Oshtoo!"
Mingled with them were calls of Jacinto, partly in Spanish, partly in the Indian tongue and partly in English.
"It is a raid by vampire bats!" was all Tom and Ned could distinguish. "We shall have to light fires to keep them away, if we can succeed. Every one grab up a club and strike hard!"
"Come on!" cried Tom, getting on some clothes by the light of his gleaming electric light which he had set on his cot.
"You're not going out there, are you?" asked Ned.
"I certainly am! If there's a fight I want to be in it, bats or anything else. Here, you have a light like mine. Flash it on, and hang it somewhere on yourself. Then get a club and come on. The lights will blind the bats, and we can see to hit 'em!"
