"Then the quicker we skip the better," were the aide-de-camp's words. "Get us to Reno fast as you can, Dean. Strike for the road again as soon as we're well beyond their buffalo. Now for it! There's something behind all this bogus hunt business, and Folsom knows what it is."

And every mile of the way, until thick darkness settled down over the prairie, there was something behind the trooper cavalcade—several somethings—wary red men, young and wiry, who never let themselves be seen, yet followed on over wave after wave of prairie to look to it that no man went back from that column to carry the news of their presence to the little battalion left in charge of the new post at Warrior Gap.

It was the dark of the moon, or, as the Indians say, "the nights the moon is sleeping in his lodge," and by ten P. M. the skies were overcast. Only here and there a twinkling star was visible, and only where some trooper struck a light for his pipe could a hand be seen in front of the face. The ambulance mules that had kept their steady jog during the late afternoon and the long gloaming that followed still seemed able to maintain the gait, and even the big, lumbering wagon at the rear came briskly on under the tug of its triple span, but in the intense darkness the guides at the head of the column kept losing the road, and the bumping of the wagons would reveal the fact, and a halt would be ordered, men would dismount and go bending and crouching and feeling their way over the almost barren surface, hunting among the sage brush for the double furrow of the trail. Matches innumerable were consumed, and minutes of valuable time, and the quartermaster waxed fretful and impatient, and swore that his mules could find their way where the troopers couldn't, and finally, after the trail had been lost and found half a dozen times, old Brooks was badgered into telling Dean to let the ambulance take the lead. The driver shirked at once.

"There's no tellin' where we'll fetch up," said he. "Those mules can't see the trail if a man can't. Take their harness off and turn 'em loose, an' I suppose they can find their way to the post, but sure as you turn them loose when they've got somethin' on 'em, or behind 'em, and the doggone cussedness of the creatures will prompt them to smash things."

But the quartermaster said he'd tried it with those very mules, between Emory and Medicine Bow a dozen times, and he'd risk it. The driver could get off his seat if he wanted to, and run alongside, but he'd stay where he was.

"Let me out, please," said the engineer, and jumped to the ground, and then the cavalcade pushed on again. The driver, as ordered by an employer whom he dare not disobey, let the reins drop on the mules' backs, the troopers falling behind, the yellow ambulance and the big baggage wagon bringing up the rear.

Then, with a horseman on each side, the mules were persuaded to push on again, and then when fairly started Burleigh called to the troopers to fall back, so that the mules should not, as he expressed it, "be influenced." "Leave them to themselves and they can get along all right," said he, "but mix them up with the horses, and they want them to take all the responsibility."

And now the command was barely crawling. Brooks, heavy, languid with splitting headache, lay in feverish torpor in his ambulance, asking only to be let alone. The engineer, a subaltern as yet, felt that he had no right attempting to advise men like Burleigh, who proclaimed himself an old campaigner. The aide-de-camp was getting both sleepy and impatient, but he, too, was much the quartermaster's junior in rank. As for Dean, he had no volition whatever. "Escort the party," were his orders, and that meant that he must govern the movements of his horses and men by the wishes of the senior staff official. And so they jogged along perhaps twenty minutes more, and then there was a sudden splutter and plunge and stumble ahead, a sharp pull on the traces, a marvelously quick jerk back on the reins that threw the wheel team on their haunches, and thereby saved the "outfit," for when men and matches were hurried to the front the lead mules were discovered kicking and splashing in a mud hole. They were not only off the road by a dozen yards, but over a bank two feet high.

And this last pound broke the back of Burleigh's obstinacy. It was nearly midnight anyway. The best thing to be done was unhitch, unsaddle and bivouac until the gray light of dawn came peering over the eastward prairie, which in that high latitude and "long-day" month would be soon after three. Then they could push on to Reno.

Not until nearly eight o'clock in the morning, therefore, did they heave in sight of the low belt of dingy green that told of the presence of a stream still long miles away; and here, knowing himself to be out of danger, the major bade the weary escort march in at a walk while he hurried on. In fifteen minutes the black-hooded wagon was twisting and turning over the powdery road a good mile ahead, its dust rising high over the sage-covered desert, while the other two, with the dust-begrimed troopers, jogged sturdily on. Loring, the young engineer, had waved a cordial good-by to his old cadet acquaintance. "See you later, old man," he cried. Stone, the aide-de-camp, nodded and said, "Take care of yourself," and Burleigh said nothing at all. He was wondering what he could do to muzzle Loring in case that gifted young graduate were moved to tell what the quartermaster actually did when he heard the rush and firing out at the front on the road from Warrior Gap.
