Dan looked keenly at the creeping figures, and then an expression of satisfaction crossed his face.
"They're the Hishus, pardner!" he whispered. "An' they mean bizness at that. They're divils when they're on the warpath. Mark my word, somethin's goin' to happen in the twinklin' of an eye. The Big Lakes haven't seen 'em yet. But when they do we'll see sparks a flyin'. Thank God, they've arrived in the nick of time! We'll just wait until they git busy with the Big Lakes, an' we'll hike it outer this."
The Big Lakes had certainly been caught napping. They little expected the arrival of the Hishus, and merely kept a vigilant watch lest the prisoners behind the big columns should escape. They were delighted that they had the fugitives in such a trap. They could afford to wait until hunger drove the pale faces from their hiding place, and that this would not be long they felt sure. So while several kept strict guard the rest lolled around, laughing and chatting about the imprisoned whites.
But when several sharp reports ripped the stillness of the day, and as many bullets sang their menacing danger about their heads, they sprang to their feet in dismay, seized their rifles and dashed for cover. At first they imagined the volley came from the besieged, but when yells of derision followed the shots they knew that the Hishus were upon them.
When the first shock of surprise had passed their coolness and cunning returned. The wild savage nature was aroused. Their old implacable enemy was before them, and now old scores were to be settled. Creeping cautiously from boulder to boulder they watched their opportunity. Whenever a head showed for an instant it became a target for sure marksmen. At first they returned yell for yell, but now they were silent! Both sides realised how deadly was the game, and like tigers they crouched and watched.
From their rocky fastness Dan and Grey looked out upon the scene of conflict. Owing to their somewhat elevated position they were able to obtain a good view of all that took place. The two tribes were much closer together now, and the shots became more frequent. It seemed to be only a matter of a few minutes ere they would be engaged in a hand-to-hand encounter. The wild hatred of their savage nature would be unleashed, and terrible would be the lot of the vanquished. This Dan and Grey knew. Their fate depended upon which side should win.
"If the Hishus conquer," said the trapper, "we are safe; but if the Big Lakes, God help us! We must be ready to step outer this at the fust opportunity. Ye'd better keep the kid close."
Scarcely had Dan finished speaking ere he leaned forward, while a roar of surprise broke from his lips.
Grey looked, too, and what he saw caused his eyes to open wide with amazement. Speeding across the open, and not far away from where they were hiding, they beheld the old man whom they had met the day before. His arms were lifted in an imploring attitude. He seemed not to mind the unevenness of the ground, nor the danger to which he was exposed. He appeared to lead a charmed life as he sped into the midst of that rain of death. Grey almost held his breath as he watched. What did the man mean? Surely he must be crazy! But still he kept on. Presently he fell, and when he rose he was seen to be limping painfully. With much difficulty he scrambled to the top of a big boulder, and lifting up his arms began to speak in the Indian tongue. What he said neither Grey nor Dan could tell. That his words had little effect was evident, for the shots were as frequent as ever. How he escaped for so long was marvellous.
Grey now realised the old man's purpose. He would stop the fight between these two tribes. He was willing to act as a mediator, to lay down his life that their strife might cease. Surely the man must be crazy, or a fanatic, he thought, to risk his life in such a way for no apparent purpose. But he was no coward, that was certain, and Grey felt a thrill of admiration as he watched him standing erect in the face of that deadly fire. Then an overwhelming pity possessed him. He could not see the old man die without an effort to save his life. He longed to hurry him away, if possible, from such danger. Only a few wild heart-beats had passed since the missionary mounted the boulder, but it was sufficient time for Grey to think, and to make up his mind.
