Finn's towering form stood out clearly in the moonlight.

Finn was standing in the middle of the flat ledge outside the den, and he neither advanced or retreated a single step as Lupus drew nearer. He simply bayed, at intervals, like a minute-gun, and scratched a little at the sandy rock beneath him with his right fore-foot. Once, Warrigal, snarling savagely, ranged up alongside him, but he sent her back to the mouth of the den with a peremptory growl which admitted of no argument. "This is my affair," his growl said. "Stay you back there in the doorway." And Warrigal, like the good spouse she was, retreated to the mouth of the den. Just then Lupus landed on the rock-ledge with a hectoring snarl which betrayed extravagance in a commodity he could ill afford to waste--breath. He plunged forward upon Finn with the clumsiness of a buffalo, and, for his instruction, received a slashing bite across one shoulder and a chest thrust which sent him rolling backwards off the ledge to the trail below, on his back.

A dingo in Finn's place would have leaped upon him then, and, it may be, the fight would have ended suddenly; for even so redoubtable a foe as Lupus is of no very great account if he can be seized when on his back, with all four feet in the air. Black-tip and his companions in the rear drew in their breath sharply. They had never before seen Lupus on his back, and if he had stayed there another second he would have had their fangs to reckon with. But his reception by the stranger taught Lupus something, and the enemy that faced Finn for the second assault was a far more deadly one than the Lupus of a few moments earlier. Finn had scorned to pursue his fallen foe, but it would have been better for him if he had had less pride. The fan-shaped line of watching dingoes closed in a little as Lupus remounted the rocky ledge, with a blood-curdling snarl and an awe-inspiring exposure of his gleaming fangs. In another instant the two were at grips, and Finn realized that he was engaged in a fight for life, and a far more serious combat than any he had known before. The mere weight of impact with the wolf-dingo was sufficient to tell Finn this, and for the infinitesimal fraction of an instant he felt a sense of fatality and doom when his opponent's tremendously powerful jaws closed over the upper part of his right fore-leg.

In the next instant Finn had torn one of Lupus's ears in half, and the terrible grip on his leg was relaxed. The Wolfhound sprang completely over the wolf-dingo, and took a slashing bite at the creature's haunches as he descended. Then they rose one at the other, like bears standing erect, and meeting jaw to jaw in mid-air, with a flashing and clashing of fangs which sent a thrill of excitement along the line of watchful dingoes, who realized now that they were looking on at the greatest spectacle of their lives. Lupus missed his grip that time, but so did Finn, being unable to withstand the violent sidelong wrench which snatched the enemy's neck from his jaws. And, as they came to earth again, Lupus secured firm hold upon Finn's leg in the same grip that he had obtained before. The grip was so vice-like and punishing as to flash panic into Finn's very soul, such as an animal knows when trapped by a man's device in unyielding steel. It was only by a violent twist of his neck that he could bring his jaws into action upon Lupus at all. But panic drove, and the long, immensely powerful neck was curved sufficiently. His jaws took the wolf-dingo at the back of the head, and one of his lower canines actually penetrated Lupus's lower jaw, causing him the most excruciating pain, so that he emitted a sound more like a hoarse scream than a growl, and snatched his head back swiftly from so terrible a punishment. That was the last time in this fight that Finn's legs were in serious danger. He had learned his lesson, and from that point onward, no matter what punishment his shoulders might receive, his hanging jaws, from which the blood dripped now, effectually guarded his legs.

From this point, too, Lupus seemed to have centred all his desires upon the Wolfhound's throat; an underhold was what he sought, and in the pursuit of that he seemed prepared for, and capable of standing, any amount of punishment. The line of watching dingoes was still and silent as a line of statuary; it seemed they hardly drew breath, so intent was their preoccupation. Warrigal, too, stuck closely to her position, but she was not silent; a low, continuous snarl issued from her parted jaws, and the updrawn line of her lips showed white and glistening in the moonlight. She had been ordered to the rear by her mate, but the waiting dingoes on the trail below realized that if Finn were to be laid low, there would still be fighting to be done on that ledge of rock, and fighting of a deadly sort, at that, from which there would be no escaping.

In one sense the Wolfhound's great height was against him now, since it placed Lupus in a more favourable position for securing the underhold upon which he was intent. But, as against that, it gave Finn readier access to the hold which in all his fights hitherto he had made fatal: the hold which a terrier takes upon a rat. But Lupus was no rat, and Finn had already found more than once that even his mighty jaws were not powerful enough to give killing pressure through all the mass of harsh bristles and thick rolling skin and flesh which protected Lupus's spinal cord at the neck. Three times during the later stages of the fight Lupus managed to ward off attack with a lightning stroke of one fore-foot, the claws of which scored deep into Finn's muzzle and neck, in one case opening a lesser vein, and sending the red blood rushing over his iron-grey coat. It seemed the long claws of the wolf-dingo were almost more deadly than his snapping jaws.

The flow of his own blood seemed to madden Finn, and he made a plunge for his enemy's neck. Lupus sat erect, and, like a boxer, or a big bear, warded off the plunge with a violent, sweeping blow of his right paw. There was a quick flash of bloody, foam-flecked fangs, and the deadly paw was crushed between Finn's jaws. The pain of the crushing drew a screeching howl from Lupus, and in that same instant a powerful upward twist of Finn's neck threw him fairly on his back, snarling despairingly. One could not measure the fraction of time which elapsed between Finn's release of the crushed foot and his seizure of the throat--the deadly underhold. The wolf-dingo's bristles were thin there, and the skin comparatively soft. The fight was for life, and it was the whole of the Wolfhound's great strength that he put into his grip. Lupus's entire frame, every inch of it, writhed and twisted convulsively, like the body of a huge cat in torment. Finn's fangs sank half an inch deeper. The wolf-dingo's claws tore impotently at space, and his body squirmed almost into a ball. Finn's fangs sank half an inch deeper, and hot blood gushed between them. Lupus's great body hunched itself into an almost erect position from the shoulder-blades; he was standing on his shoulders. Then, as in a convulsion, one of his hind-legs was lowered in order that it might saw upward, scoring three deep furrows down the side of the Wolfhound's neck. Finn's fangs met in the red centre of his enemy's throat. There was a faint grunt, a final spasm of muscular activity, and then Finn drew back, and shook his dripping muzzle in the air. The fierce lord of Mount Desolation had entered upon the long sleep; his lordship was ended.

Finn sank back upon his haunches, gasping, with a length of scarlet, foam-streaked tongue dangling from one side of his jaws. The watching line of dingoes advanced two paces. Warrigal, stepping forward to her mate's side, snarled warningly. But Finn pushed her gently with his lacerated muzzle, and, turning then to the watchful dingoes below, he emitted a little whinnying sound which said plainly: "You are welcome here!" Acting upon this, Black-tip moved slowly, deferentially forward, and climbed the flat ledge of rock, his bushy tail respectfully curled between his legs. Long and thoroughly he sniffed at the dead body of the terrible Lupus, and then he looked round at his still waiting companions, and whined as he walked back toward them. In twos and threes the dingoes followed Black-tip's lead, and climbed the flat rock to sniff their dead tyrant, and satisfy themselves that he had indeed entered upon the long sleep. And the gesture in Finn's direction, with which they turned away from the rock, was as near to being a salutation, an obeisance, as anything that mortal dingo has ever achieved. And when the last of the band, reinforced now by half a dozen others who had been hastily summoned from their hunting near by, had paid his visit of inspection, Finn did a curious thing, which probably no dingo would ever have done. He moved slowly forward on his aching limbs, gripped the dead body firmly by the neck, and heaved it down from the flat rock to the trail below. Then he barked aloud, a message which said plainly--

"Here is your old lord and tyrant! Take him away, and leave me now!"
