Not more than twenty minutes later, followed by Bremilu and Zangamon, Stern was making way through the thick-laced wood and jungle.

Awed, terrified by their first sight of trees and by the upper world which to them was naught but marvel and danger, the two Merucaans followed close behind their guide. Even so would you or I cling to the Martian who should land us on that ruddy planet and pilot us through some huge, inchoate and grotesque growth of things to us perfectly unimaginable.

“Oh, master, we shall see the patriarch soon?” asked Bremilu, in a strange voice--a voice to him astonishingly loud, in the clear air of night upon the surface of the world. “Soon shall we speak with him and--”

“Hark! What's that?” interrupted Stern, pausing, the while he gripped his pistol tighter.

From afar, though in which direction he could not say, a vague, dull roar made itself heard through the forest.

Sonorous, vibrant, menacing, it echoed and died; and then again, as once before, Stern heard that strange, hollow booming, as of some mighty drum struck by a muffled fist.

A cry? Was that a cry, so distant and so faint? Beast-cry, or call of night-bird, shrill and far?

Stern shuddered, and with redoubled haste once more pushed through the vague path he and Beatrice had made from the barrens to Settlement Miffs.

Presently, followed by the two colonists who dared not let him for a moment out of their sight, he reached the brow of the cañon. His hand flash-lamp showed him the rough path to the terrace.

With fast-beating heart he ran down it, unmindful of the unprotected edge or the sheer drop to the rocks of New Hope River, far below.
