Each man waited for that single shot which would precipitate the fight. Even in their lawlessness the rude instinct of the duello swayed them. The officer of the law recognized the principle as well as its practical advantage in a collision, but he hesitated to sacrifice one of his men in an attack on the barn, which would draw the fire of McKinstry at that necessarily fatal range. As a brave man he would have taken the risk himself, but as a prudent one, he reflected that his hurriedly collected posse were all partisans, and if he fell the conflict would resolve itself into a purely partisan struggle without a single unprejudiced witness to justify his conduct in the popular eye. The master also knew this; it had checked his first impulse to come forward as a mediator; his only reliance now was on Mrs. McKinstry's restraint and the sheriff's forbearance. The next instant both seemed to be imperilled.

“Well, why don't you wade in?” sneered Dick McKinstry; “who do you reckon's hidden in the barn?”

“I'll tell ye,” said a harsh, passionate voice from the hill-side. “It's Cressy McKinstry and the school-master hidin' in the hay.”

Both parties turned quickly towards the intruder who had approached them unperceived. But the speech was followed by a more startling revulsion of sentiment as Mrs. McKinstry's voice rang out from the barn, “You lie, Seth Davis!”

The brief advantage offered to the sheriff in Davis's advent as a neutral witness, was utterly lost by this unlooked-for revelation of Mrs. McKinstry's presence in the barn! The fates were clearly against him! A woman in the fight, and an old one at that! A white woman to be forcibly ejected! In the whole unwritten code of Southwestern chivalry there was no such precedent.

“Stand back,” he said disgustedly to his followers, “stand back and let the d——d barn slide. But you, Hiram McKinstry, I'll give YOU five minutes to shake yourself clear of your wife's petticoats and git!” His blood was up now—the quicker from his momentary weakness and the trick of which he thought himself a dupe.

Again the fatal signal seemed imminent, again it was delayed. For Hiram McKinstry, with clanking spurs and rifle in hand stepped from behind the barn, full in the presence of his antagonists.

“Ez to my gitten in five minits,” he began in his laziest, drowsiest manner, “we'll see when the time's up. But jest now words hev passed betwixt my wife and Seth Davis. Afore anythin' else goes on yer, he's got to take HIS back. My wife allows he lies; I allow he lies too, and I stan' here to say it.”

The right of personal insult to precedence of redress was too old a frontier principle to be gainsaid now. Both parties held back and every eye was turned to where Seth Davis had been standing. But he had disappeared.

Where?
