‘It moves, Will; come and help me! Push hard! I can feel it giving way.’
Slowly the huge stone moved, and there was an opening wide enough for them to pass through.
Edgar went through first, but came back quickly when Will called out the opening was closing up again and the stone swinging back into its place. Edgar had just time to step back into the cave when the stone swung to.
‘That is the way the other must have closed up,’ said Edgar. ‘It made no noise. Let us have another try, the cave on the other side is much larger than this.’
‘If we get through,’ said Will, ‘the stone will swing back, and we shall be worse off than before. Yacka will not be able to find us when he returns.’
‘He will follow us,’ said Edgar. ‘He must know of this cave and the way to enter it.’
‘If you mean going on, I will follow you,’ said Will.
They moved the stone again, and this time they both stepped quickly through before it swung back.
The cave they entered was, as Edgar said, much larger than the one they had just left. It was lighted by the same dim light, but they could not see from whence it came.
‘Here is another knob,’ said Will. ‘They must have been made by the blacks. Perhaps we are on the way to the cave of Enooma. I wonder what Yacka will think if we reach it before him.’
