CHAPTER XXX.
A GUESS.
Standing in the door of the building, his figure so wrapped in gloom that it was invisible to the fierce Murhapas, Professor Grimcke cautiously peered out upon the multitude that were clamorously seeking the death of himself and comrade.
The horde seemed to be everywhere.

They were glaring over the river bank, behind which they could find secure shelter by merely dropping their heads; they were crouching at the corners of the adjacent houses, the king's residence affording screen to fully a score.

Not yet fully recovered from their panic, they appeared to be awaiting the leadership of some strong man who held the fire-arms of the explorers in less dread than they.
A form rose upright along the Xingu, at the upper portion of the line of savages.

In the full moonlight he was as clearly revealed as if at mid-day.
It was with strange feelings that Professor Grimcke saw that this individual belonged to the same race as himself.

He was one of the two white men that had lived for years among the Murhapas and who had instigated the furious assault upon them.
"You have earned your fate," muttered the German, bringing his unerring Winchester once more to his shoulder, and sighting as best he could at the unconscious miscreant, who appeared to be conversing with some one sitting on the ground at his side.
The finger of Grimcke was pressing the trigger when, yielding to an unaccountable impulse, he lowered the weapon.
