At the very moment he was about to make the attempt, Grimcke and Long gave him unexpected help by opening their united fire from the front upon the warriors marshalling for the decisive charge.

This afforded him just the pretext he wanted, to order the Murhapas to hasten to the other side of the building to assist in what was in contemplation there, though, even with such a movement under way, it will be seen that the right place for a portion of the savages was at the rear, in order to head off the very thing that was attempted.

Thus it was, that, while the two explorers were congratulating themselves on the success of their clever scheme, they never suspected that its success was due to their giant friend, who kept himself so well in the background that neither of them caught sight of him.

Having got his men away, Ziffak slipped back with the purpose of carrying out the rest of the plan he had formed; but before he could reach the rear entrance, he caught sight of Professor Grimcke running like a deer toward the woods.

Ziffak was puzzled, not knowing that his friend had preceded him, and he dashed into the building to hurry him out.  As he came in at one door, Waggaman and the Murhapas swarmed in at the other, and pandemonium was let loose.

The certainty of another murderous fire from the rifles of the defenders caused some lagging at the threshold, but those in the rear forced those at the front forward, and the next moment the mob was inside.

Still there was no sound of firearms, though, the savages were crowding into both apartments.  Some one kicked the ashes from the embers, and the blaze which followed made known the astounding fact that both of the white men had fled.

Ziffak seemed to be in a towering rage because such a blunder had been made, and called upon the fleetest runners to follow him.

Out of the door he went as if shot from the throat of a columbiad, with a procession of sinewy-limbed warriors at his heels.  All ran as fast as they could, though none were his equal in fleetness.

It need hardly be said that Ziffak took mighty good care that he did not pursue the course of Professor Grimcke, and presumably that of his companion who preceded him.  Instead of aiming for the woods, he diverged toward the river, and seemed to find it necessary to shout and yell every second or two at the top of his voice.

His followers may have imagined he was laboring under uncontrollable rage or deemed it necessary to keep their courage up to the highest point by such means; but the two fugitives who had joined each other in the woods, and were picking their way with the utmost care, held a strong suspicion that the prodigious shouts were intended for their special benefit.  At any rate, they accepted them as such, and took pains to continue their flight in a different course from that of the howling Murhapas.

It did not require Ziffak long to find out that the fugitives were irrecoverably gone, and he came back with his report to the king.
