So, indeed, they all thought, but each of them felt strangely anxious nevertheless, and when Mackay fetched his rifle from his tent and began to blaze away methodically, they were not long in following his lead. The bells had been some time out of range when the first shot was fired, but suddenly their harsh jangling burst afresh on their ears, and to their surprise and dismay they seemed to be heading towards the south.

"Keep your popguns going," said Mackay. "The Shadow must have lost his nerve and got slewed."

So was the young bushman condemned and abused while he pursued his erratic course, and Jack came in for more sympathy than he would have appreciated had he been within hearing.

"What in thunder can the howlin' idiot mean by zig-zagging like that?" exclaimed Never Never Dave, listening to the intermittent peals of the bells with deep concern. Then faintly over the mulga scrub came the yells of the discomfited blacks, and at once Golden Flat camp was aroused to strenuous action; scarcely a word was spoken, each man gripped his rifle, and almost as one body, they made a wild burst in the direction from which the alarming sounds had come. And Bob, though almost in a high fever from the effects of the wound in his head, entirely forgot his weakness, and kept pace with Mackay.

Silent and grim, like a raging Nemesis, the small company hurried on their vengeful way; but they had not gone far when they became aware of a slight commotion in the bush directly in their path, and almost before they could realize it, the great hulking forms of the camels loomed out through the darkness, with Jack at their head.

"Well, I'll be kicked! And why isn't ye slaughtered, young feller?" demanded Nuggety Dick, in helpless amazement. "We never dreamt o' seein' ye alive again——"

"Where's the Shadow, Jack?" interrupted Mackay.

Jack laughed. "He's acting decoy for the blacks," he said.

The big man seemed to tremble with suppressed emotion.
