“Here, you’ve gone down far enough,” cried Josh. “I’m going to haul you up now.”

“No, no!” shouted Will, the excitement of being in antagonism with his helpmate driving away the last particle of nervousness. “Lower away!”

Josh hesitated for a moment, and made a movement as if to rub his nose, but his hands were engaged, and he got over the difficulty by bending down his head and applying the itching organ to the rope, after which he shook his head fiercely, but went on lowering.

“He’s getting too much for me a gashly sight, this boy,” he growled.

There was ample line to lower Will right down to the surface of the water, though he was unaware of the fact, as he swung gently to and fro, eagerly scanning every clear space of the rock through which the shaft had been cut; and where the wall was dry, in spite of the time that had elapsed since the work was done the marks of the miners’ picks and hammers were as clear as if the blows had fallen only a few months before. As the lad looked, too, he could, in his own disappointment, realise how great must have been that of the adventurers whose capital was being expended day after day cutting on and finding nothing but grey, hard granite, with here and there bands of ruddy stone suggestive of the presence of tin, but in such minute quantities that it would not pay for the labour of lifting out and crushing the stone.

Granite, granite, nothing but granite; and now the rope seemed to cut harshly into his legs, and a curious aching sensation set in, half numbing the arm that clung to the rope, for the lad had been so deeply interested in his search that he had not once altered his position.

“Look out, Josh!” he said, “I’m going to change hands.”

“Here, I’m a-going to haul you up now,” replied Josh, the great shaft acting like a speaking-tube, so that conversation was easy enough.

“Not yet,” shouted back Will; and as the rope seemed to glide down he changed his position a little, taking the candle in the numbed hand, a fresh grip with his right, and altering his seat so that the line did not cut so harshly.

As he did so another slight touch of nervousness came over him; and in spite of himself he began to glance at the knot he had made in the rope, and then at the candle to see how much longer it would last, to find that it was half burned down and that the length of time it would keep burning must guide his descent. He was a little disheartened too, for it had not entered much into his calculations that clever men must have well examined that shaft when it was being cut, and that they would have made the discovery if it was to be made.
