"Then, Robert, you go," said the hunter, "and mind, too, that you get back soon, because my throat is parching. I'd like to have one deep drink before the warriors attack."

Robert followed Tayoga, and, obeying his instructions, was soon at the fountain, where he drank once, twice, thrice, and then once more of the finest water he could recall. Then, deeply grateful for the Onondaga's observation, he climbed back, and the hunter took his turn.

"It was certainly good, Tayoga," he said, when he was back in position. "Some men don't think much of water, but none of us can live without it. You've saved our lives."

"Perhaps, O Great Bear," responded the Onondaga, "but if the bushes below continue to shake as they are doing we shall have to save them again. Ah!"

The exclamation, long drawn but low, was followed by the leap of his rifle to the shoulder, and the pressing of his finger on the trigger. A stream of fire sprang from the muzzle of the long barrel to be followed by a yell in one of the thickets clustering on the slope. A savage rose to his feet, threw up his arms and fell headlong, his body crashing far below on the rocks. Robert shut his eyes and shivered.

"He was dead before he touched earth, lad," said the hunter. "Now the others are ready to scramble back. Look how the bushes are shaking again!"

Robert had shut his eyes only for a moment, and now he saw the scrub shaking more violently than ever. Then he had a fleeting glimpse of brown bodies as all the warriors descended rapidly. Anyone of the three might have fired with good aim, but they did not raise their rifles. Since their enemies were retreating they would let them retreat.

"They're all back in the valley now," said the hunter after a little while, "and they'll think a lot before they try the steep ascent a second time. Now it's a question of patience, and they hope we'll become so weak from thirst that we'll fall into their hands."

"Tandakora and his warriors would be consumed with anger if they knew of our spring," said Tayoga.

"They'll find out about it soon," said Robert.
