58. Why can’t Tom & Becky find their way back in the cave?

Tom and Becky wandered into a part of the cave where there were bats..... they ran and got lost.

Under the roof vast knots of bats had packed themselves together, thousands in a bunch; the lights disturbed the creatures and they came flocking down by hundreds, squeaking and darting furiously at the candles. Tom knew their ways and the danger of this sort of conduct. He seized Becky’s hand and hurried her into the first corridor that offered; and none too soon, for a bat struck Becky’s light out with its wing while she was passing out of the cavern. The bats chased the children a good distance; but the fugitives plunged into every new passage that offered, and at last got rid of the perilous things. Tom found a subterranean lake, shortly, which stretched its dim length away until its shape was lost in the shadows.
