"What is it?" asked the doctor.

"Smoke," panted Wilkins. "The Hualpais saw it up the mountain south of the Pass."

Gwynne's haggard face was dreadful to see. The jar of the rough gallop had started afresh the bleeding in his head and the doctor begged him to wait and let him dress it again, but the only answer was a look of fierce determination, and renewed spurring of his wretched horse. He was soon abreast the head of the column, but even then kept on. Turner hailed him and urged him to stay with them, but entreaty was useless. "I am going after Sieber," was the answer. "Did you see the smoke?"

"No, Gwynne; but Sieber and the Hualpais are sure a big column went up and that it means the Apaches can't be far away. We're bound to get them. Don't wear yourself out, old fellow; stay with us!" but Gwynne pressed on. Far out to the front he could see that one of the Indian scouts had halted and was making signs. It took five minutes hard riding to reach him.

"What did you see? What has happened?" he gasped.

"Heap fire!" answered the Hualpai. "See?" But Gwynne's worn eyes could only make out the great mass of the mountain with its dark covering of stunted trees. He saw, however, that the scout was eagerly watching his comrades now so long a distance ahead. Presently the Indian shouted in excitement:

"Fight! Fight! Heap shoot, there!" and then at last the father's almost breaking heart regained a gleam of hope; a new light flashed in his eyes, new strength seemed to leap through his veins. Even his poor horse seemed to know that a supreme effort was needed and gamely answered the spur. Waving his hat above his head and shouting back to Turner "Come on!" the captain dashed away in pursuit of Sieber. Turner's men could hear no sound, but they saw the excitement in the signal; saw the sudden rush of Gwynne's steed, and nothing more was needed. "Gallop," rang the trumpet, and with carbines advanced and every eye on the dark gorge, still three miles before them, the riders of the beautiful "chestnut sorrel" troop swept across the plains.

Meantime the savage fight was going on and the defense was sorely pressed. Covered by the smoke caused by fresh armfuls of green wood hurled upon the fiery furnace in front of the cave, the vengeful Apaches had crawled to within a few yards of where the little breastwork had stood. Obedient to Pike's stern orders Kate had crept to the remotest corner of the recess and lay there flat upon the rock, holding Nellie in her arms. The corporal had bound a handkerchief about his left arm, for some of the besiegers, finding bullets of no avail, were firing Tonto arrows so that they fell into the mouth of the cave, and one of these had torn a deep gash midway between the elbow and the shoulder. Another had struck him on the thigh. Jim, too, had a bloody scratch. It stung and hurt and made him grit his teeth with rage and pain. Little Ned, sorely against his will, was screened by his father's saddle and some blankets, but he clung to his Ballard and the hope of at least one more shot.

And still, though sorely pressing the besieged, the Indians kept close under cover. The lessons of the morning had taught them that the pale faces could shoot fast and straight. They had lost heavily and could afford no more risks. But every moment their circle seemed closer to the mouth of the cave, and though direct assault could not now be made because of their great bonfire, the dread that weighed on Pike was that they should suddenly rush in from east and west. "In that event," said he to Jim, "we must sell our lives as dearly as possible. I'll have two at least before they can reach me."

Hardly had he spoken when bang came a shot from beyond the fire; a bullet zipped past his head and flattened on the rock well back in the cave. Where could that have come from? was the question. A little whiff of blue smoke sailing away on the wind from the fork of a tall oak not fifty feet in front told the story. Hidden from view of the besieged by the drifting smoke from the fire a young warrior had clambered until he reached the crotch and there had drawn up the rifle and belt tied by his comrades to a "lariat." Straddling a convenient branch and lashing himself to the trunk he was now in such a position that he could peer around the tree and aim right into the mouth of the rocky recess, and only one leg was exposed to the fire of the defense.
