As soon also as our heroes had satisfied their hunger and thirst, they all rose, and dividing the packages amongst them, led the way towards the two apertures in the lower end. Ned and his men had no objection to these new attendants carrying the loads, since they were forced to trust them now. But they stuck tenaciously to their weapons and ammunition.

They entered a narrow passage outside the column, and after pacing along it towards the cliff face, they began once more to descend.

Fifty steps in one direction along the punctured inner side of the cliffs, brought them to a flight of steps at the opposite angle. When that other fifty was reached, another flight at the first angle met them, and so on, until they had descended three thousand of these steps.

It was a fatiguing journey after their heavy exertions, for the amazons hurried them along without a pause. They were either in great haste, or else did not wish any more investigations to be made of this underground region.

The light was growing fainter also, as it was nearing sunset, yet our heroes were able to see, at each turn of the stairs, passages leading into other chambers. From several of these, as they got near the bottom, they heard a clanking sound, as if miners were at work.

“I say, boys,” said Ned, “do you hear? They are still working this gold-mine. What about the mirage now?”

Since meeting these female warriors our heroes had no longer any thought of turning back. There seemed no danger of perishing from want or thirst. As for other dangers, they were quite ready to encounter these.

“This is an adventure and no mistake. I guess we are bound to see some strange things before long,” answered Fred, excitedly.

It was nearly dark before they crossed the last step and found themselves once more on level ground.

Before them spread a wide and long apartment with a huge fire burning in the centre. A strong menagerie-like perfume greeted their nostrils along with the more pleasant odours of cooking. As they entered, a wild chorus of savage yells echoed through the vault.
