Yarpe looked. "Hell! The cavalry! We're euchred—clean."

Over the hill behind the officer appeared a squadron of gray horse, marching in single file, winding down the trail like a long serpent, spotted with blue and buff, the sun sparkling fitfully from their polished brass and steel. When Curtis turned to the sheriff his face was pale with excitement for the first time, quivering, exultant. "You'll have the federal troops to deal with now," he said. "At last we are on equal terms."

A deep silence fell on the mob. Every ruffian of them seemed suddenly frozen into immobility, and each sat with head turned and eyes wide-staring, watching the coming of the blue-shirted horsemen.

As the officer approached he was distinguishable as a powerful, smooth-faced young man in a captain's uniform. As his eyes rested on Curtis his plump, red face broke into a broad smile. It was plain that he was Irish, and not averse to a bit of a shindy.

Riding straight up to the agent, he formally saluted, and in a deep, dry, military voice, said:

"Colonel Daggett presents his compliments to Captain Curtis and tenders Squadron B, at your service. Captain Maynard in command."

With equally impersonal decorum Curtis acknowledged the courtesy.

"Captain Curtis returns the compliment, and thanks Captain Maynard for his prompt and most opportune arrival—Jack, I'm mighty glad to see you."

Maynard dismounted and they shook hands. "Same to you, old man. What's all the row?"

A clear, distant, boyish voice cried, "By columns of four into line!" and the bugle, breaking voice, caused the hair of the agent's head to stand; turning, he saw the squadron taking form as it crossed the stream. It required his most heroic effort to keep the tears from his eyes as his ear heard the dull rattle of scabbards and he watched the splendid play of the gray horses' legs and broad chests as they came on, weary but full of spirit yet. There was something inexorable in their advance. In their order, their clean glitter, their impersonal grace, was expressed the power of the general government.
