Edging along the base of the cliff, for the darts and stones still descended, regardless of friend or foe, the defenders blazed away at their enemies, till the latter recovered from their fright and returned to the attack.
Not till they were in grave danger of being cut off did Mr. McKay and his companions return to the cave once more to endure the torments of the smoke-laden atmosphere.
This time the savages did not leave them in peace. With poised weapons the wily warriors waited on either side of the entrance, while others descended from the terrace and procured fresh fuel.
Splashing their faces with water, and fanning the noxious fumes with portions of their clothes, the defenders strove to cool their parched and heated bodies, realising that another half-hour would doubtless see the end of the unequal struggle.
"I'm not going to be smoked out like a rat in a hole," exclaimed Ellerton. "I'll make a dash for it and die in the open."
"It's the only way," replied Mr. McKay. "If we are to die we must die like Britons, fighting to the last."
Hardly had the forlorn party made this desperate decision, when a sharp ear-splitting explosion, followed almost immediately by another, was heard without the cave. Yells of terror and noisy surprise arose, and the savages fled right and left.
For a moment the defenders were unable to grasp the meaning of the interruption, till Andy shouted: "Hurrah! A rescue!" and overcome by mental and bodily strain, he fell on the floor in a swoon.
Terence and Ellerton were about to rush to the mouth of the cave, but Mr. McKay restrained them.
"Lie down!" he exclaimed. "They're firing with shell, and we shall be blown to atoms if we go outside."
