"What!" shouted Riggs, hotly. He dropped his right hand significantly to his hip.

"Don't throw your gun. It might go off," said Dale.

Whatever Riggs's intention had been--and it was probably just what Dale evidently had read it--he now flushed an angry red and jerked at his gun.

Dale's hand flashed too swiftly for Helen's eye to follow it. But she heard the thud as it struck. The gun went flying to the platform and scattered a group of Indians and Mexicans.

"You'll hurt yourself some day," said Dale.

Helen had never heard a slow, cool voice like this hunter's. Without excitement or emotion or hurry, it yet seemed full and significant of things the words did not mean. Bo uttered a strange little exultant cry.

Riggs's arm had dropped limp. No doubt it was numb. He stared, and his predominating expression was surprise. As the shuffling crowd began to snicker and whisper, Riggs gave Dale a malignant glance, shifted it to Helen, and then lurched away in the direction of his gun.

Dale did not pay any more attention to him. Gathering up Helen's baggage, he said, "Come on," and shouldered a lane through the gaping crowd. The girls followed close at his heels.

"Nell! what 'd I tell you?" whispered Bo. "Oh, you're all atremble!"

Helen was aware of her unsteadiness; anger and fear and relief in quick succession had left her rather weak. Once through the motley crowd of loungers, she saw an old gray stage-coach and four lean horses. A grizzled, sunburned man sat on the driver's seat, whip and reins in hand. Beside him was a younger man with rifle across his knees. Another man, young, tall, lean, dark, stood holding the coach door open. He touched his sombrero to the girls. His eyes were sharp as he addressed Dale.

"Milt, wasn't you held up?"

"No. But some long-haired galoot was tryin' to hold up the girls.

Wanted to throw his gun on me. I was sure scared," replied Dale, as he deposited the luggage.

Bo laughed. Her eyes, resting upon Dale, were warm and bright. The young man at the coach door took a second look at her, and then a smile changed the dark hardness of his face.

Dale helped the girls up the high step into the stage, and then, placing the lighter luggage, in with them, he threw the heavier pieces on top.

"Joe, climb up," he said.

"Wal, Milt," drawled the driver, "let's ooze along."

Dale hesitated, with his hand on the door. He glanced at the crowd, now edging close again, and then at Helen.

"I reckon I ought to tell you," he said, and indecision appeared to concern him.

"What?" exclaimed Helen.

"Bad news. But talkin' takes time. An' we mustn't lose any."

"There's need of hurry?" queried Helen, sitting up sharply.

"I reckon."

"Is this the stage to Snowdrop?

"No. That leaves in the mornin'. We rustled this old trap to get a start to-night."

"The sooner the better. But I--I don't understand," said Helen, bewildered.

"It'll not be safe for you to ride on the mornin' stage," returned Dale.

"Safe! Oh, what do you mean?" exclaimed Helen. Apprehensively she gazed at him and then back at Bo.

"Explainin' will take time. An' facts may change your mind. But if you can't trust me--"

"Trust you!" interposed Helen, blankly. "You mean to take us to Snowdrop?"

"I reckon we'd better go roundabout an' not hit Snowdrop," he replied, shortly.

"Then to Pine--to my uncle--Al Auchincloss?

"Yes, I'm goin' to try hard."

Helen caught her breath. She divined that some peril menaced her. She looked steadily, with all a woman's keenness, into this man's face. The moment was one of the fateful decisions she knew the West had in store for her. Her future and that of Bo's were now to be dependent upon her judgments. It was a hard moment and, though she shivered inwardly, she welcomed the initial and inevitable step. This man Dale, by his dress of buckskin, must be either scout or hunter. His size, his action, the tone of his voice had been rea.s.suring. But Helen must decide from what she saw in his face whether or not to trust him. And that face was clear bronze, unlined, unshadowed, like a tranquil mask, clean-cut, strong-jawed, with eyes of wonderful transparent gray.

"Yes, I'll trust you," she said. "Get in, and let us hurry. Then you can explain."

"All ready, Bill. Send 'em along," called Dale.

He had to stoop to enter the stage, and, once in, he appeared to fill that side upon which he sat. Then the driver cracked his whip; the stage lurched and began to roll; the motley crowd was left behind. Helen awakened to the reality, as she saw Bo staring with big eyes at the hunter, that a stranger adventure than she had ever dreamed of had began with the rattling roll of that old stage-coach.

Dale laid off his sombrero and leaned forward, holding his rifle between his knees. The light shone better upon his features now that he was bareheaded. Helen had never seen a face like that, which at first glance appeared darkly bronzed and hard, and then became clear, cold, aloof, still, intense. She wished she might see a smile upon it. And now that the die was cast she could not tell why she had trusted it. There was singular force in it, but she did not recognize what kind of force. One instant she thought it was stern, and the next that it was sweet, and again that it was neither.

"I'm glad you've got your sister," he said, presently.

"How did you know she's my sister?"

"I reckon she looks like you."

"No one else ever thought so," replied Helen, trying to smile.

Bo had no difficulty in smiling, as she said, "Wish I was half as pretty as Nell."

"Nell. Isn't your name Helen?" queried Dale.

"Yes. But my--some few call me Nell."

"I like Nell better than Helen. An' what's yours?" went on Dale, looking at Bo.

"Mine's Bo. Just plain B-o. Isn't it silly? But I wasn't asked when they gave it to me," she replied.

"Bo. It's nice an' short. Never heard it before. But I haven't met many people for years."

"Oh! we've left the town!" cried Bo. "Look, Nell! How bare! It's just like desert."

"It is desert. We've forty miles of that before we come to a hill or a tree."

Helen glanced out. A flat, dull-green expanse waved away from the road on and on to a bright, dark horizon-line, where the sun was setting rayless in a clear sky. Open, desolate, and lonely, the scene gave her a cold thrill.
