Both drew their guns from their holsters and lowered them till the barrels lay even with the trousers seams. They awaited the word to fire which Bill Lang, who stood at an angle equidistant from the two men, was to give.

"Wait!" Jack called, in a tone which indicated that something had recurred to him. Then a half laugh from him fell on the brilliant, shining, hard silence with something of the sound of a pebble slipping over glare ice.

"Leddy, it has just occurred to me that we are both foolish—honestly, we are!" he said. "The idea when Arizona is so sparsely settled of our starting out to depopulate it in such a premeditated manner on such a beautiful morning, and all because I was such an inept whistler! Why, if I had realized what a perfectly bad whistler I was I would never have whistled again. If my whistle hurt your feelings I am sorry, and I—"

"No, you don't!" yelled Leddy. "I've waited long enough! It's fight, you—"

"Oh, all right! You are so emphatic," Jack answered. His voice was still pleasant, but shot with something metallic. The very shadow of him seemed to stiffen with the stiffening of his muscles.

"Ready!" called Bill Lang.

The ruling passion that had carved six notches on his gun-handle overwhelmed Pete Leddy. At least, let us give him the benefit of the doubt and say that this and not calculation was responsible for his action. Before the word for preparation was free of Lang's lips, and without waiting for the word to fire, his revolver came up in a swift quarter-circle. He was sure of his aim at that range with a ready draw. Again and again he had thus hit his target in practice and six times he had winged his man by such agile promptness.

With the flash from the muzzle all the members of the gallery rose on hands and knees. They were as sure that there was to be a seventh notch as of their identity. There was no question in their minds but Pete had played a smart trick. They had known from the first that he would win. And the proof of it was in the sudden, uncontrollable movement of the adversary.

Jack whirled half round. He was falling. But even as he fell he was still facing his adversary. He plunged forward unsteadily and came to rest on his left elbow. A trickle of blood showed on the chap of his left leg, which had tightened as his knee twisted under him. Leddy's rage had been so hot that for once his trigger finger had been too quick. He had aimed too low. But he was sure that he had done for his man and he looked triumphantly toward the gallery gods whose hero he was. They had now risen to their feet. In answer to their congratulations he waved his left hand, palm out, in salutation. His gun-hand had dropped back to his trousers seam.

Even as it dropped, Jack's revolver had risen, his own gun-hand steadied in the palm of his left hand, which had an elbow in the sand for a rest. Victor and spectators, in their preoccupation with the relief and elation of a drama finished, had their first warning of what was to come in a voice that did not seem like the voice of the tenderfoot as they had heard it, but of another man. And Leddy was looking at a black hole in a rim of steel which, though twenty yards away, seemed hot against his forehead, while he turned cold.
