“Do you think he'll tackle the buckboard, too?” whispered Curtis.

Crosby laughed joyously and drew a long breath of relief.

“No, he's all right now,” he answered. “Don't you see, he doesn't know about Patten or the buckboard. He's probably well on his way to the post now. I delayed the game at the stage there on purpose to give him a good start. He's safe by now.”

“It was a close call,” laughed the other. “He's got to give us a dinner for helping him out of this.”

“We'd have caught him red-handed,” said Crosby, “if we'd been five minutes sooner. Lord!” he gasped. “It makes me cold to think of it. The men would have shot him off his horse. But what a story for those women! I hope I'll be there when they tell it. If Ranson can keep his face straight, he's a wonder.” For some moments they raced silently neck by neck, and then Curtis again leaned from his saddle. “I hope he HAS turned back to the post,” he said. “Look at the men how they're keeping watch for him. They're scouts, all of them.”

“What if they are?” returned Crosby, easily. “Ranson's in uniform—out for a moonlight canter. You can bet a million dollars he didn't wear his red mask long after he heard us coming.”

“I suppose he'll think we've followed to spoil his fun. You know you said we would.”

“Yes, he was going to shoot us,” laughed Crosby. “I wonder why he packs a gun. It's a silly thing to do.”

The officers fell apart again, and there was silence over the prairie, save for the creaking of leather and the beat of the hoofs. And then, faint and far away, there came the quick crack of a revolver, another, and then a fusillade. “My God!” gasped Crosby. He threw himself forwards digging his spurs into his horse, and rode as though he were trying to escape from his own men.

No one issued an order, no one looked a question; each, officer and enlisted man, bowed his head and raced to be the first.
