Just about this period, without saying anything at home, Gwyn and Joe, who had passed a good deal of time beneath the cliffs at low-water, to try and find out anything suggestive of an attempt being made to destroy the mine by an explosive—finding nothing, however, but a few places where the rocks had been chipped down by the point—determined to examine the spot from which they had escaped by the help of Vores.

The latter being consulted, expressed his willingness to go, and Sam Hardock was asked to accompany them, but he shook his head.

“No,” he said, “my legs are all right again; but there aren’t nothing to be got by it, and I should advise you all not to go.”

But another actor in the late adventures expressed his willingness to be of the party, and tore off at full speed one morning when, well provided with candles, matches and magnesium wire, they started off, following the edge of the cliff, till, about a mile west of the mine, Grip seemed to take a plunge into the sea and disappear.

“Knows his way again,” said Vores, laughing; and upon the spot where the dog had disappeared being reached, a way down for some forty or fifty feet was found, close by which a narrow opening, with the debris lying about as the pieces had been chipped, met the eye.

On approaching this, Grip made his appearance, barking loudly, and then turned and went in again.

“Will you go first, sir?” said Vores; and Gwyn led, candles being lit as soon as they were a little way in.

They followed the descent for the most part on all-fours, and lastly by creeping and pushing the lanthorns on in front, till at last the long, low, sloping cavern was reached where so terrible a time had been passed.

The floor was littered with broken stones, the result of the shot that was fired, and for a few moments Gwyn knelt there listening, expecting to hear the hiss and roar of the wind dislodged by the pressure of the water; but the only sound heard was the rustling and panting of those who were following; and as soon as Joe was out they went together to the descent into the mine.

Here there was no way down farther than about twenty feet; then the water lay calm, smooth and black.
