Now they had reached the hill. At its summit they paused to recover their breath and take a look at the camp.
The fires were deserted. A quarter of a mile out on the plain they saw half a dozen of their pursuers speeding toward the hill. The rest were already concealed in the nearer thickets of the bottom.
"We must beat them to the chasm!" said the young Indian.
As he spoke Wabi turned and led the way again.
Rod's heart fell like a lump within him. We must beat them to the chasm! Those words of Wabi's brought him to the terrible realization that his own powers of endurance were rapidly ebbing. His race behind Mukoki to the burning cabin had seemed to rob the life from the muscles of his limbs, and each step now added to his weakness. And the chasm was a mile beyond the dip, and the entrance into that chasm still two miles farther. Three miles! Could he hold out?
He heard Mukoki thumping along behind him; ahead of him Wabi was unconsciously widening the distance between them. He made a powerful effort to close the breach, but it was futile. Then from close in his rear there came a warning halloo from the old Indian, and Wabi turned.
"He run t'ree mile to burning cabin," said Mukoki. "He no make chasm!"
Rod was deathly white and breathing so hard that he could not speak. The quick-witted Wabi at once realized their situation.
"There is just one thing for us to do, Muky. We must stop the Woongas at the dip. We'll fire down upon them from the top of the hill beyond the lake. We can drop three or four of them and they won't dare to come straight after us then. They will think we are going to fight them from there and will take time to sneak around us. Meanwhile we'll get a good lead in the direction of the chasm."
He led off again, this time a little slower. Three minutes later they entered into the dip, crossed it safely, and were already at the foot of the hill, when from the opposite side of the hollow there came a triumphant blood-curdling yell.
