"There's bound to be lots more of it lying around," said Jack, soothingly, as they retraced their steps.

When they reached the exit the light of the candle showed them that the tunnel here swung off to the left at a right angle, and at this point the passage was considerably wider than they had at first judged, probably owing to the difficulty the natives had experienced in making such a sharp turn. But the eye could distinguish nothing beyond the radius of the feeble illumination; all was oppressively murky and damp and repellent.

"That's our road, boys," said Mackay, pointing with his candle into the gloomy cavern which led into the heart of the mountain. "But before we start on our journey we'll get out an' make our final arrangements, an' change our wardrobe to suit the situation."

In a few minutes they were all on the surface once more, eagerly talking over their prospects, for, strangely enough, the dangerous aspect of their projected journey through the mountain was for the moment lost on them, so completely had the glamour of the golden tunnel exercised its subtle influence. Mackay, however, quickly regained his control.

"We must remember, boys," he cautioned, "that we have no ordinary natives to contend with, an' before we leave this camp it will be necessary to attend to some details which may be helpful to us afterwards."

"What would you suggest?" asked Bob.

"In the first instance," Mackay replied, "we should hide the camel-packs containing our provisions. We can easily do that out among the sand on the other side o' the springs. It won't take us half an hour altogether."

"But what about the camels?" interjected Jack.

"They are a good distance away, my lad, an' they're no' hobbled. They'll just have to take their chance; but I don't think there's much risk in that direction, after all, for Misery can't stand the sight o' a nigger, an' if he bolted, the rest would follow, an' we could track them up afterwards just as I had to do before in this same district."

It was yet early in the day, and though Emu Bill was loath to delay their tour of discovery even for five minutes, he was brought to see the wisdom of Mackay's advice. Within half an hour the camp had assumed a bare and desolate appearance, only the heavier mining implements being left at the base of the mountain. Then they gathered round the cleft in the rock, and hurriedly prepared for their work of subterranean exploration. It had been agreed that the party should don the robes of the deceased warriors in order to lessen the chances of detection should any natives be encountered while traversing the mysterious passage, but now they saw that whereas there were five persons to transform into savages, there were but four of the long furry coverings, although the feathered decorations for completing their sartorial equipment were more numerous than necessary.
