On the second day Wabi revisited the subterranean world beyond the cataract. When he came back he had discovered the secret of the treasure in the pool. The gold came from the cavern. The soft sand through which they had followed the strange light was rich in dust and nuggets. During the floods of spring water came into the cavern from somewhere, and flowing for a brief space out through the mouth of the cave brought with it the precious burden of treasure-laden sand which was dumped into the pool. The constant wash of the cataract had caused most of the sand to overflow into the running stream, but the heavier gold-dust and nuggets remained in the trap into which they had fallen.

But the joy that came of this discovery was subdued by thoughts of John Ball. The gold meant everything to Rod, the realization of his hopes and ambitions; and he knew that it meant everything to his mother, and to all those who belonged to Mukoki and Wabigoon. But the gold could wait. They had already accumulated a small fortune, and they could return for the rest a little later. At present they must do something for John Ball, the man to whom they were indebted for all that they had found, and to whom the treasure really belonged. On the third day Rod laid his plans before Wabi and Mukoki.

"We must take John Ball back to the Post as quickly as we can," he said. "It is our only chance of saving him. If we start now, while the water in the creek is deep enough to float our canoe, we can make Wabinosh House in ten or fifteen days."

"It will be impossible to paddle against the swift current," said Wabi.

"That is true. But we can put John Ball into the canoe and tow him up-stream. It will be a long wade and hard work, but—"

He looked at Wabi in silence, then added,

"Do we want John Ball to live, or do we want him to die?"

"If I thought he would live I would wade a thousand miles to save him," rejoined the young Indian. "It means little to us but work. We know where the rest of the gold is and can return to it within a few weeks."

If there had been a doubt in the boys' minds as to the right course to pursue John Ball settled it himself that very afternoon. He awakened from an unusually long stupor. His eyes were burning with a new light, and as Rod bent over him he whispered softly, but distinctly,

"Dolores—Dolores—Where is Dolores?"
