Tom and Becky in the cave

Tom and Becky walked into the cave. They held their candles high and saw names and dates which were written on the walls by other people. Suddenly they were in a part of the cave without any writing on the walls. They used candle smoke to write their own names on the rock and then walked on.

Soon they came to a little stream of water. The cave wall looked like a frozen waterfall. Tom went behind the stone waterfall and found an opening in the rock. They started to walk down into the earth. They went deeper and deeper into the cave. Tom and Becky made many candle smoke marks on the walls to show the way back. It was exciting.

They soon found themselves in a huge open space that was full of bats. There were thousands of them. The light from their candles woke up the bats, and they flew at the candle flames. Tom knew this was dangerous, so he took Becky's hand to hurry her away, but one of the bats followed and put out Becky's candle with its wings. The bats followed them for a long time, but Tom and Becky ran into every new passage that they came to, and at last they got away from the bats.
