Edgar jumped down and held up his head, and in a few moments Will recovered his senses.
‘I warned you,’ said Yacka.
‘It was a pure accident,’ said Will.
Edgar made no remark, but he thought it a strange coincidence.
A peculiar rumbling sound was heard, and Yacka listened intently. In a moment there was a terrific crash. The rock upon which they stood shook, and the sides of the cave seemed to rock.
The slab upon which rested the White Spirit of Enooma rocked to and fro, and the figure seemed to move.
Crash followed crash, and roar upon roar. The forces of Nature seemed to have suddenly burst loose, and a general upheaval was taking place. So violent became the oscillation, that they were compelled to lie down on the floor of the cave.
‘It is Enooma’s welcome to her own people,’ said Yacka, who was not in the least afraid.
‘It is an earthquake,’ said Edgar in an awestruck voice.
‘What is an earthquake?’ said Yacka.
