“Stop where you are,” said Courthorne presently. “Now then, turn round. Move a finger or open your lips, and I’ll have great pleasure in shooting you. In the meanwhile you can endeavour to make favour with whatever saint is honoured by the charge of you.”

Shannon smiled in a fashion that resembled a snarl as once more a blink of moonlight shone down upon them, and in place of showing apprehension, his young white face, from which the bronze had faded, was venomous.

“And my folks were Orange, but what does that matter now?” said he. “There’ll be one of us in——to-morrow, but for the shame ye put on Larry ye’ll carry my mark there with ye.”

Courthorne looked at him with a little glow in his eyes. “You haven’t felt mine yet,” he said. “You will probably talk differently when you do.”

It may have been youthful bravado, but Trooper Shannon laughed. “In the meanwhile,” he said, “I’m wondering why you’re wearing an honest man’s coat and cap. Faith, if he saw them on ye, Witham would burn them.”

Courthorne returned no answer and the moonlight went out, but they stood scarcely three feet apart, and one of them knew that any move he made would be followed by the pressure of the other’s finger on the trigger. He, however, did not move at all, and while the birches roared about them they stood silently face to face, the man of birth and pedigree with a past behind him and blood already upon his head, and the raw lad from the bush, his equal before the tribunal that would presently judge their quarrel.

In the meanwhile Trooper Shannon heard a drumming of hoofs that grew steadily louder before Courthorne apparently noticed the sound, and his trained ears told him that the rustlers’ horses were coming down the trail. Now they had passed the forking, and when the branches ceased roaring again he knew they had floundered down the first of the declivity, and it would be well to wait a little until they had straggled out where the trail was narrow and deeply rutted. No one could turn them hastily there, and the men who drove them could scarcely escape the troopers who waited them, if they blundered on through the darkness of the bush. So five breathless minutes passed, Trooper Shannon standing tense and straight with every nerve tingling as he braced himself for an effort, Courthorne stooping a little with forefinger on the trigger, and the Marlin rifle at his hip. Then through a lull there rose a clearer thud of hoofs. It was lost in the thrashing of the twigs as a gust roared down again, and Trooper Shannon launched himself like a panther upon his enemy.

He might have succeeded, and the effort was gallantly made, but Courthorne had never moved his eyes from the shadowy object before him, and even as it sprang, his finger contracted further on the trigger. There was a red flash and because he fired from the hip the trigger guard gashed his mitten. He sprang sideways, scarcely feeling the bite of the steel, for the lad’s hand brushed his shoulder. Then there was a crash as something went down heavily amidst the crackling twigs. Courthorne stooped a little, panting in the smoke that blew into his eyes, jerked the Marlin lever, and, as the moon came through again, had a blurred vision of a white, drawn face that stared up at him still with defiance in its eyes. He looked down into it as he drew the trigger once more.

Shannon quivered a moment, and then lay very still, and it was high time for Courthorne to look to himself, for there was a shouting in the bluff, and something came crashing through the undergrowth. Even then his cunning did not desert him, and flinging the Marlin down beside the trooper, he slipped almost silently in and out among the birches and swung himself into the saddle of a tethered horse. Unlooping the bridle from a branch, he pressed his heels home, realizing as he did it that there was no time to lose, for it was evident that one of the troopers was somewhat close behind him, and others were coming across the river. He knew the bluff well, and having no desire to be entangled in it was heading for the prairie, when a blink of moonlight showed him a lad in uniform riding at a gallop between him and the crest of the slope. It was Trooper Payne, and Courthorne knew him for a very bold horseman.

Now, it is possible that had one of the rustlers, who were simple men with primitive virtues as well as primitive passions, been similarly placed, he would have joined his comrades and taken his chance with them, but Courthorne kept faith with nobody unless it suited him, and was equally dangerous to his friends and enemies. Trooper Shannon had also been silenced for ever, and if he could cross the frontier unrecognized, nobody would believe the story of the man he would leave to bear the brunt in place of him. Accordingly he headed at a gallop down the winding trail, while sharp orders and a drumming of hoofs grew louder behind him, and hoarse cries rose in front. Trooper Payne was, it seemed, at least keeping pace with him, and he glanced over his shoulder as he saw something dark and shadowy across the trail. It was apparently a horse from which two men were struggling to loose its burden.
