"I must tell Welton of our plan," said Bob; "I wouldn't for the world have to spring this on him unprepared. What would he think of me?"

"We'll see him to-morrow wait for Ware, you know."

no, next day; we have to

"Am I forgiven for doing my plain duty?" asked Bob a trifle mischievously.

"Only if our scheme works," declared Amy. Her manner changed to one of great seriousness. "I know your way is brave and true, believe me I do. And I know what it costs you to follow it. I respect and admire the quality in men that leads them so straightly along the path. But I could not do it. Ideas and things are inspiring and great and to be worked for with enthusiasm and devotion, I know. No one loves the Service more than I, nor would make more personal sacrifices for her. But people are warm and living, and their hearts beat with human life, and they can be sorry and glad, happy and broken-hearted. I can't tell you quite what I mean, for I cannot even tell myself. I only feel it. I could turn my thumbs down on whole cohorts of senators and lawyers and demagogues that are attacking us in Washington and read calmly in next day's paper how they had been beheaded recanting all their sins against us. But I couldn't get any nearer home. Why, the other day Ashley told me to send a final and peremptory notice of dispossession to the Main family, over near Bald Knob, and I couldn't do it. I tried all day. I knew old Main had no business there, and is worthless and lazy and shiftless. But I kept remembering how his poor old back was bent over. Finally I made Ashley dictate it, and tried to keep thinking all the time that I was nothing but a machine for the transmission of his ideas. When it comes to such things I'm useless, and I know I fall short of all higher ideals of honour and duty and everything else."

"Thank God you do," said Bob gravely.

ARE returned to headquarters toward evening of the next day. He had ridden hard and long, but he listened to Thorne's definition of his new duties with kindling eye, and considerable appearance of quiet satisfaction. Bob met him outside

the office.

"You aren't living up to your part, Ware," said he, with mock anxiety. "According to Hoyle you ought to draw your gun, whirl the cylinder, and murmur gently, Aha!"

"Why should I do that?" asked Ware, considerably mystified.

"To see if your weapon is in order, of course."

"How would a fool trick like that show whether my gun's in shape?"

"Hanged if I know," confessed Bob, "but they always do that in books and on the stage."

"Well, my gun will shoot," said Ware, shortly.

It was then too late to visit Welton that evening, but at a good hour the following morning Bob announced his intention of going over to the mill.

"If you're going to be my faithful guardian, you'll have to walk," he told Ware. "My horse is up north somewhere, and there isn't another saddle in camp."

"I'm willing," said Ware; "my animals are plumb needy of a rest."

At the last moment Amy joined them.

"I have a day off instead of Sunday," she told them, "and you're the first humans that have discovered what

two feet are made for. I never can get anybody to walk two steps with me," she complained.

"Never tried before you acquired those beautiful gray elkskin boots with the ravishing hobnails in 'em," chaffed Bob.

Amy said nothing, but her cheeks burned with two red spots. She chatted eagerly, too eagerly, trying to throw into the expedition the air of a holiday excursion. Bob responded to her rather feverish gaiety, but Ware looked at her with an eye in which comprehension was slowly dawning. He had nothing to add to the rapid-fire conversation. Finally Amy inquired with mock anxiety, over his unwonted silence. "I'm on my job," replied Ware briefly.

This silenced her for a moment or so, while she examined the woods about them with furtive, searching glances as though their shadows might conceal an enemy.

To Bob, at least, the morning conduced to gaiety, for the air was crisp and sparkling with the wine of early fall. Down through the sombre pines, here and there, flamed the delicate pink of a dogwood, the orange of the azaleas, or the golden yellow of aspens ripening already under the hurrying of early frosts. The squirrels, Stellar's jays, woodpeckers, nuthatches and chickadees were very busy scurrying here and there, screaming gossip, or moving diligently and methodically as their natures were. All the rest of the forest was silent. Not a breath of wind stirred the tallest fir-tip or swayed the most lofty pine branch. Through the woodland spaces the sunlight sparkled with the inconceivable brilliance of the higher levels, as though the air were filled with glittering particles in suspension, like the mica snowstorms of the peep shows inside a child's candy egg.

They dipped into the cañon of the creek and out again through the yellow pines of the other side. They skirted the edge of the ancient clearing for the almost prehistoric mill that had supplied early settlers with their lumber, and thence

looked out through trees to the brown and shimmering plain lying far below.

"My, I'm glad I'm not there!" exclaimed Amy fervently; "I always say that," she added.

"A hundred and eleven day before yesterday, Jack Pollock says," remarked Bob.

So at last they gained the long ridge leading toward the mill and saw a hundred feet away the mill road, and the forks where their own wagon trail joined it.

At this point they again entered the forest, screened by young growth and a thicket of alders.

"Look there," Amy pointed out. "See that dogwood, up by the yellow pine. It's the most splendiferous we've seen yet. Wait a minute. I'm going to get a branch of it for Mr. Welton's office. I don't believe anybody ever picks anything for him.”

"Let me

began Bob; but she was already gone, calling back over her shoulder.

"No; this is my treat!"

The men stopped in the wagon trail to wait for her. Bob watched with distinct pleasure her lithe, active figure making its way through the tangle of underbrush, finally emerging into the clear and climbing with swift, sure movements to the little elevation on which grew the beautiful, pinkleaved dogwoods. She turned when she had gained the level of the yellow pine, to wave her hand at her companions. Even at the distance, Bob could make out the flush of her cheeks and divine the delighted sparkle of her eyes.

But as she turned, her gesture was arrested in midair, and almost instantly she uttered a piercing scream. Bob had time to take a half step forward. Then a heavy blow on the back of his neck threw him forward. He stumbled and fell on his face. As he left his feet, the crash of two revolver shots in quick succession rang in his ears.

LDHAM'S cold rage carried him to the railroad and into his berth. Then, with the regular beat and throb of the carwheels over the sleepers, other considerations forced themselves upon him. Consequences demanded recognition.

The land agent had not for many years permitted himself to act on impulse. Therefore this one lapse from habit alarmed him vaguely by the mere fact that it was a lapse from habit. He distrusted himself in an unaccustomed environment of the emotions.

But superinduced on this formless uneasiness were graver considerations. He could not but admit to himself that he had by his expressed order placed himself to some extent in Saleratus Bill's power. He did not for a moment doubt the gun-man's loyal intentions. As long as things went well he would do his best by his employer-if merely to gain the reward promised him only on fulfillment of his task. But it is not easy to commit a murder undetected. And if detected, Oldham had no illusions as to Saleratus. Bill. The gun-man would promptly shelter himself behind his principal.

As the night went on, and Oldham found himself unable to sleep in the terrible heat, the situation visualized itself. Step by step he followed out the sequence of events as they might be, filling in the minutest details of discovery, exposure and ruin. Gradually, in the tipped balance of after midnight, events as they might be became events as they surely would be. Oldham began to see that he had made a fearful mistake. No compunction entered his mind.
