"Fact!" continued Boyle eagerly. "It's the same card I stuck in his hat--there's the greasy mark in the corner. How the devil did it--how did HE get here?"

"Better ax him," said Foster grimly, "ef he's anywhere round."

"But I say, Foster, I don't like the look of this at all! Miss Cantire is alone, and"--

But a burst of laughter from Foster and the mail agent interrupted him.

"That's so," said Foster. "That's your best holt! Keep it up! You jest tell her that! Say thar's another Injin skeer on; that that thar bloodthirsty ole 'Fleas in His Blanket' is on the warpath, and you're goin' to shed the last drop o' your blood defendin' her! That'll fetch her, and she ain't bin treatin' you well! G'lang!"

The horses started forward under Foster's whip, leaving Boyle standing there, half inclined to join in the laugh against himself, and yet impelled by some strange instinct to take a more serious view of his discovery. There was no doubt it was the same card he had given to the Indian. True, that Indian might have given it to another--yet by what agency had it been brought there faster than the coach traveled on the same road, and yet invisibly to them? For an instant the humorous idea of literally accepting Foster's challenge, and communicating his discovery to Miss Cantire, occurred to him; he could have made a funny story out of it, and could have amused any other girl with it, but he would not force himself upon her, and again doubted if the discovery were a matter of amus.e.m.e.nt. If it were really serious, why should he alarm her? He resolved, however, to remain on the road, and within convenient distance of her, until she returned to the coach; she could not be far away. With this purpose he walked slowly on, halting occasionally to look behind.

Meantime the coach continued its difficult ascent, a difficulty made greater by the singular nervousness of the horses, that only with great trouble and some objurgation from the driver could be prevented from shying from the regular track.

"Now, wot's gone o' them critters?" said the irate Foster, straining at the reins until he seemed to lift the leader back into the track again.

"Looks as ef they smelt suthin--b'ar or Injin ponies," suggested the mail agent.

"Injin ponies?" repeated Foster scornfully.

"Fac'! Injin ponies set a hoss crazy--jest as wild hosses would!"

"Whar's yer Injin ponies?" demanded Foster incredulously.

"Dunno," said the mail agent simply.

But here the horses again swerved so madly from some point of the thicket beside them that the coach completely left the track on the right. Luckily it was a disused trail and the ground fairly good, and Foster gave them their heads, satisfied of his ability to regain the regular road when necessary. It took some moments for him to recover complete control of the frightened animals, and then their nervousness having abated with their distance from the thicket, and the trail being less steep though more winding than the regular road, he concluded to keep it until he got to the summit, when he would regain the highway once more and await his pa.s.sengers. Having done this, the two men stood up on the box, and with an anxiety they tried to conceal from each other looked down the canyon for the lagging pedestrians.

"I hope Miss Cantire hasn't been stampeded from the track by any skeer like that," said the mail agent dubiously.

"Not she! She's got too much grit and sabe for that, unless that drummer hez caught up with her and unloaded his yarn about that kyard."

They were the last words the men spoke. For two rifle shots cracked from the thicket beside the road; two shots aimed with such deliberateness and precision that the two men, mortally stricken, collapsed where they stood, hanging for a brief moment over the dashboard before they rolled over on the horses' backs. Nor did they remain there long, for the next moment they were seized by half a dozen shadowy figures and with the horses and their cut traces dragged into the thicket. A half dozen and then a dozen other shadows flitted and swarmed over, in, and through the coach, reinforced by still more, until the whole vehicle seemed to be possessed, covered, and hidden by them, swaying and moving with their weight, like helpless carrion beneath a pack of ravenous wolves. Yet even while this seething congregation was at its greatest, at some unknown signal it as suddenly dispersed, vanished, and disappeared, leaving the coach empty--vacant and void of all that had given it life, weight, animation, and purpose--a mere skeleton on the roadside. The afternoon wind blew through its open doors and ravaged rack and box as if it had been the wreck of weeks instead of minutes, and the level rays of the setting sun flashed and blazed into its windows as though fire had been added to the ruin. But even this presently faded, leaving the abandoned coach a rigid, lifeless spectre on the twilight plain.

An hour later there was the sound of hurrying hoofs and jingling accoutrements, and out of the plain swept a squad of cavalrymen bearing down upon the deserted vehicle. For a few moments they, too, seemed to surround and possess it, even as the other shadows had done, penetrating the woods and thicket beside it. And then as suddenly at some signal they swept forward furiously in the track of the destroying shadows.

Miss Cantire took full advantage of the suggestion "not to hurry" in her walk, with certain feminine ideas of its lat.i.tude. She gathered a few wild flowers and some berries in the underwood, inspected some birds'

nests with a healthy youthful curiosity, and even took the opportunity of arranging some moist tendrils of her silky hair with something she took from the small reticule that hung coquettishly from her girdle. It was, indeed, some twenty minutes before she emerged into the road again; the vehicle had evidently disappeared in a turn of the long, winding ascent, but just ahead of her was that dreadful man, the "Chicago drummer." She was not vain, but she made no doubt that he was waiting there for her. There was no avoiding him, but his companionship could be made a brief one. She began to walk with ostentatious swiftness.

Boyle, whose concern for her safety was secretly relieved at this, began to walk forward briskly too without looking around. Miss Cantire was not prepared for this; it looked so ridiculously as if she were chasing him!

She hesitated slightly, but now as she was nearly abreast of him she was obliged to keep on.

"I think you do well to hurry, Miss Cantire," he said as she pa.s.sed.

"I've lost sight of the coach for some time, and I dare say they're already waiting for us at the summit."

Miss Cantire did not like this any better. To go on beside this dreadful man, scrambling breathlessly after the stage--for all the world like an absorbed and sentimentally belated pair of picnickers--was really TOO much. "Perhaps if YOU ran on and told them I was coming as fast as I could," she suggested tentatively.

"It would be as much as my life is worth to appear before Foster without you," he said laughingly. "You've only got to hurry on a little faster."

But the young lady resented this being driven by a "drummer." She began to lag, depressing her pretty brows ominously.

"Let me carry your flowers," said Boyle. He had noticed that she was finding some difficulty in holding up her skirt and the nosegay at the same time.

"No! No!" she said in hurried horror at this new suggestion of their companionship. "Thank you very much--but they're really not worth keeping--I am going to throw them away. There!" she added, tossing them impatiently in the dust.

But she had not reckoned on Boyle's perfect good-humor. That gentle idiot stooped down, actually gathered them up again, and was following!

She hurried on; if she could only get to the coach first, ignoring him!

But a vulgar man like that would be sure to hand them to her with some joke! Then she lagged again--she was getting tired, and she could see no sign of the coach. The drummer, too, was also lagging behind--at a respectful distance, like a groom or one of her father's troopers.

Nevertheless this did not put her in a much better humor, and halting until he came abreast of her, she said impatiently: "I don't see why Mr.

Foster should think it necessary to send any one to look after me."

"He didn't," returned Boyle simply. "I got down to pick up something."

"To pick up something?" she returned incredulously.

"Yes. THAT." He held out the card. "It's the card of our firm."

Miss Cantire smiled ironically. "You are certainly devoted to your business."

"Well, yes," returned Boyle good-humoredly. "You see I reckon it don't pay to do anything halfway. And whatever I do, I mean to keep my eyes about me." In spite of her prejudice, Miss Cantire could see that these necessary organs, if rather flippant, were honest. "Yes, I suppose there isn't much on that I don't take in. Why now, Miss Cantire, there's that fancy dust cloak you're wearing--it isn't in our line of goods--nor in anybody's line west of Chicago; it came from Boston or New York, and was made for home consumption! But your hat--and mighty pretty it is too, as YOU'VE fixed it up--is only regular Dunstable stock, which we could put down at Pine Barrens for four and a half cents a piece, net. Yet I suppose you paid nearly twenty-five cents for it at the Agency!"

Oddly enough this cool apprais.e.m.e.nt of her costume did not incense the young lady as it ought to have done. On the contrary, for some occult feminine reason, it amused and interested her. It would be such a good story to tell her friends of a "drummer's" idea of gallantry; and to tease the flirtatious young West Pointer who had just joined. And the apprais.e.m.e.nt was truthful--Major Cantire had only his pay--and Miss Cantire had been obliged to select that hat from the government stores.

"Are you in the habit of giving this information to ladies you meet in traveling?" she asked.

"Well, no!" answered Boyle--"for that's just where you have to keep your eyes open. Most of 'em wouldn't like it, and it's no use aggravating a possible customer. But you are not that kind."

Miss Cantire was silent. She knew she was not of that kind, but she did not require his vulgar indors.e.m.e.nt. She pushed on for some moments alone, when suddenly he hailed her. She turned impatiently. He was carefully examining the road on both sides.

"We have either lost our way," he said, rejoining her, "or the coach has turned off somewhere. These tracks are not fresh, and as they are all going the same way, they were made by the up coach last night. They're not OUR tracks; I thought it strange we hadn't sighted the coach by this time."

"And then"--said Miss Cantire impatiently.

"We must turn back until we find them again."

The young lady frowned. "Why not keep on until we get to the top?" she said pettishly. "I'm sure I shall." She stopped suddenly as she caught sight of his grave face and keen, observant eyes. "Why can't we go on as we are?"

"Because we are expected to come back to the COACH--and not to the summit merely. These are the 'orders,' and you know you are a soldier's daughter!" He laughed as he spoke, but there was a certain quiet deliberation in his manner that impressed her. When he added, after a pause, "We must go back and find where the tracks turned off," she obeyed without a word.

They walked for some time, eagerly searching for signs of the missing vehicle. A curious interest and a new reliance in Boyle's judgment obliterated her previous annoyance, and made her more natural. She ran ahead of him with youthful eagerness, examining the ground, following a false clue with great animation, and confessing her defeat with a charming laugh. And it was she who, after retracing their steps for ten minutes, found the diverging track with a girlish cry of triumph. Boyle, who had followed her movements quite as interestedly as her discovery, looked a little grave as he noticed the deep indentations made by the struggling horses. Miss Cantire detected the change in his face; ten minutes before she would never have observed it. "I suppose we had better follow the new track," she said inquiringly, as he seemed to hesitate.

"Certainly," he said quickly, as if coming to a prompt decision. "That is safest."

"What do you think has happened? The ground looks very much cut up," she said in a confidential tone, as new to her as her previous observation of him.

"A horse has probably stumbled and they've taken the old trail as less difficult," said Boyle promptly. In his heart he did not believe it, yet he knew that if anything serious had threatened them the coach would have waited in the road. "It's an easier trail for us, though I suppose it's a little longer," he added presently.

"You take everything so good-humoredly, Mr. Boyle," she said after a pause.

"It's the way to do business, Miss Cantire," he said. "A man in my line has to cultivate it."
