Tarzan had seen enough of such strange happenings recently to have some idea as to what he might expect;but this time Bolgani did not alter his form as he came slowly toward the young ape-man.
Tarzan was a bit puzzled, too, that he felt no desire to rush frantically to some place of safety, as had been the sensation most conspicuous in the other of his new and remarkable adventures. He was just himself now, ready to fight, if necessary; but still sure that no flesh and blood gorilla stood before him.
The thing should be fading away into thin air by now, thought Tarzan, or changing into something else;yet it did not. Instead it loomed clear-cut and real as Bolgani himself, the magnificent dark coat glistening with life and health in a bar of sunlight which shot across the cabin through the high window behind the young Lord Greystoke. This was quite the most realistic of his sleep adventures, thought Tarzan, as he passively awaited the next amusing incident.
And then the gorilla charged. Two mighty, calloused hands seized upon the ape-man, great fangs were bared close to his face, a hideous growl burst from the cavernous throat and hot breath fanned Tarzan's cheek, and still he sat grinning at the apparition. Tarzan might be fooled once or twice, but not for so many times in succession!
He knew that this Bolgani was no real Bolgani, for had he been he never could have gained entrance to the cabin, since only Tarzan knew how to operate the latch.
The gorilla seemed puzzled by the strange passivity of the hairless ape. He paused an instant with his jaws snarling close to the other's throat, then he seemed suddenly to come to some decision. Whirling the ape-man across a hairy shoulder, as easily as you or I might lift a babe in arms, Bolgani turned and dashed out into the open, racing toward the great trees.
Now, indeed, was Tarzan sure that this was a sleep adventure, and so grinned largely as the giant gorilla bore him, unresisting, away. Presently, reasoned Tarzan, he would awaken and find himself back in the cabin where he had fallen asleep. He glanced back at the thought and saw the cabin door standing wide open.
This would never do! Always had he been careful to close and latch it against wild intruders. Manu, the monkey, would make sad havoc there among Tarzan's treasures should he have access to the interior for even a few minutes.
The question which arose in Tarzan's mind was a baffling one.
Where did sleep adventures end and reality commence? How was he to be sure that the cabin door was not really open?
Everything about him appeared quite normal--there were none of the grotesque exaggerations of his former sleep adventures.
It would be better then to be upon the safe side and make sure that the cabin door was closed--it would do no harm even if all that seemed to be happening were not happening at all.
Tarzan essayed to slip from Bolgani's shoulder; but the great beast only growled ominously and gripped him tighter.
With a mighty effort the ape-man wrenched himself loose, and as he slid to the ground, the dream gorilla turned ferociously upon him, seized him once more and buried great fangs in a sleek, brown shoulder.
The grin of derision faded from Tarzan's lips as the pain and the hot blood aroused his fighting instincts.
Asleep or awake, this thing was no longer a joke! Biting, tearing, and snarling, the two rolled over upon the ground.
The gorilla now was frantic with insane rage. Again and again he loosed his hold upon the ape-man's shoulder in an attempt to seize the jugular; but Tarzan of the Apes had fought before with creatures who struck first for the vital vein, and each time he wriggled out of harm's way as he strove to get his fingers upon his adversary's throat.
At last he succeeded--his great muscles tensed and knotted beneath his smooth hide as he forced with every ounce of his mighty strength to push the hairy torso from him.
And as he choked Bolgani and strained him away, his other hand crept slowly upward between them until the point of the hunting knife rested over the savage heart--there was a quick movement of the steel-thewed wrist and the blade plunged to its goal.
Bolgani, the gorilla, voiced a single frightful shriek, tore himself loose from the grasp of the ape-man, rose to his feet, staggered a few steps and then plunged to earth.
There were a few spasmodic movements of the limbs and the brute was still.
Tarzan of the Apes stood looking down upon his kill, and as he stood there he ran his fingers through his thick, black shock of hair. Presently he stooped and touched the dead body. Some of the red life-blood of the gorilla crimsoned his fingers. He raised them to his nose and sniffed.
Then he shook his head and turned toward the cabin.
The door was still open. He closed it and fastened the latch.
Returning toward the body of his kill he again paused and scratched his head.
If this was a sleep adventure, what then was reality? How was he to know the one from the other? How much of all that had happened in his life had been real and how much unreal?
He placed a foot upon the prostrate form and raising his face to the heavens gave voice to the kill cry of the bull ape.
Far in the distance a lion answered. It was very real and, yet, he did not know. Puzzled, he turned away into the jungle.
No, he did not know what was real and what was not;but there was one thing that he did know--never again would he eat of the flesh of Tantor, the elephant.
