Dusk found him camped on the first steep pitches of the mesa. And, as he had done a hundred times before in the same spot, he ate a cold meal in the dark and rolled up in his blankets twenty yards from the duffel, with the rifle close by.
Nor did he light a blaze in the morning, but journeyed on up the slopes until at last he stood on the mesa's rim and looked across a valley curtained by heat fog to that far-off irregular patch of earth representing Powder. The town did not hold his interest so much as a small trail of dust in the more immethate foreground, which, after a half hour's patient watching, proved to be the wake of a wagon going north on the Snake River Road. Thus satisfied, Lin left the panorama behind him, dipping into the corrugated sand and clay surface of the mesa.
Beauty Chatto'll probably be ahead of me, he mused. He's got a fresh horse and he always travels fast. Besides, he knew I was coming in right away, and it's natural he'd want to push in first. I'd better watch the front more.
He pulled the rifle from its boot and laid it across the saddle, studying the hilly contours that rose before him. It was a region admirably fashioned for ambuscade: at no place was there more than three or four hundred yards' level interval between the sudden convolutions of land. Ballou, on reaching some such eminence, had only a partial view of the way ahead before plunging down into the succeeding hollow. Thus he proceeded.
Toward noon he changed his direction and began a zigzagging from right to left. One particularly bald and prominent dome was the mark by which he steered, although instead of going straight toward it he bore well off to the right and dismounted. Nearby, on a small knoll, he lay for twenty minutes or so, sharply scanning the adjoining ridges. Satisfied that he wasn't being watched, he made a complete circle of the dome and then struck directly down a gully. Presently horses and rider dropped out of sight; the gully shot downward at a sharp angle and a draught of air struck Ballou's face. Turning a shelf of rock, he found himself before a cave that was high enough and wide enough to admit both himself and his two animals. Riding into it, he came to a stop and got down.
A more secluded spot could not have been found in all the mesa. The location and shape of it concealed him from any eye, nor could it be discovered by chance wayfarers, unless through blind accident they might have followed the tortuous path around the dome and down the gully.
The ashes of many campfires littered the floor. A little farther back a table and chairs of lodgepole had been constructed, and still rearward were two bunks, built against the rock wall. It was quite evidently a rendezvous of some permanence, and to Lin at least it was a home hardly less important in the last several weeks than his own down in the sultry valley. Stripping the horses, he picketed them at the mouth of the cave, fed them and then built a small fire over which he cooked himself the first good meal in two days. The supply of provisions he stowed away in a kind of rock cupboard. After smoking a reflective cigarette, he turned in for a sound sleep, the rifle within arm's reach.
He awoke, fresh and bouyant, well before dawn. Going to the cave's entrance, he saw the stars gleaming, bright and cold, and heard the swishing of the wind as it passed directly over the gully. The horses moved patiently around their pickets. The nearer rubbed his muzzle against Lin's shirt and pulled at the rope.
"Boy," Lin said, running a hand along the animal's neck, "you get a rest today, which I reckon you won't mind at all When it comes to slogging along without complaint you'd make most any critter on two legs ashamed of himself. Get out of my pocket, you rascal, I haven't got an ounce of sugar. If I hadn't been rushed away from the valley so sudden like, I might've thought to bring some. But that's not our fault either. Anyhow, oats'll have to hold you for a spell. Now, let's get to business."
The affair at the schoolhouse still rankled when he thought of it. But here in the cold, crisp dark, surrounded on all sides by the mystery of nature's handiwork, and catching at intervals the strong, aromatic scent of pine and sage, he was soothed to a certain degree of tranquillity. The mesa never failed him when he had asked peace and comfort of it. Towering high above the valley's heat and the valley's strife, it was a sure and swift healer of souls. To Lin Ballou it was a refuge where he might be thrown back to his own resources and for a time live in the closest contact with the earth.
But this day he had business to do. To the east, morning thrust its first dim beam of light above the horizon. Turning back, Lin kindled a fire and made himself flapjacks and coffee. He gave both horses a good measure of oats and saddled the riding animal. From the rock cupboard he drew a bottle and a few small pieces of iron. Thrusting them in his pocket, he stamped out the fire and led the way up the gully. There was need this day for a good deal of speed. Mounting, he swung east once more and began a long journey around the bald dome. It was somewhat cold. Throwing away his cigarette, he drew up the collar of his coat and broke into a subdued lament about the cowboy who wished to be buried in the lone prairie. The pony stuck up his ears and moved with sure feet among the rocks.
To Lin Ballou it was familiar country. The map of it stood quite plainly in his mind. On his right hand, not more than a mile distant, he might find a bunch of Double Jay stock. To the left, double that distance, was the summer ground of W. W. Offut's brand—that very same gentleman who had refused to speak to him in Powder. And at various parts of the mesa other herds were grazing. Farther east the mesa took a sharp drop and merged with the Flats.
At this particular time he had another point of the mesa in mind. In the paling shadows a clump of trees stood silhouetted by themselves, and toward this he moved. Within twenty feet of them he left the horse and crawled upward until he had gained a place somewhat sheltered by their spindling trunks. Directly before him the land formed another of the innumerable hollows to be found throughout the mesa's extent. More interesting to Lin was the glow of a campfire in the pit of that hollow. He settled down to a steady observation.
Well, Nig Chatto's there, anyhow, he decided. Probably Beauty, too. Stands to reason he hoofed it back as fast as he could. Damn fools, they haven't got a mite of caution any more. Why don't they change their camp once in a while?
The answer, he told himself, was that they had scarcely anything to fear. It was a remote spot, not visited by line riders. Moreover, the Chattos had a kind of cunning about their methods that made them extremely bold. Nothing of an incriminating nature would ever be found around their fire. The work they did was accomplished elsewhere.
The sky turned from deep blue to gray and in quick succession to azure and rose. Fixed within the shelter of the trees, Lin watched the camp below. Presently he saw Beauty Chatto roll out of his blankets and sit before the fire. Nig, a figure somewhat smaller and less ugly than his brother, was already by the blaze, making breakfast. Their horses were picketed near at hand.
Satisfied with his discovery, Lin crawled back down the slope and swung into the saddle. This time he retraced a part of his trail to the cave and then forked off into another gully and rose rapidly, with no great caution, upward and to the north. In half an hour this took him to the commanding point of the entire mesa from which he might observe and—if anyone might be straying in the neighborhood—be observed. Shading his eyes, he spent a few moments surveying the distant hollows. At one particular point he found what he wished to see. Over there, browsing quietly, was one herd of W. W. Offut's stock. "Get along, Brimstone," he told the horse. And he thought: Lets see, this is Tuesday. Offut's riders don't come around this way until tomorrow. That leaves us clear. Quick and quiet does it if it's to be done at all. I can take care of the Chattos, but I don't want to fight any of Offut's buckaroos. "Step, Brimstone."
Ho put in a half hour traversing the rolling ground. Passing over a hillock, he drove his horse directly into a herd of browsing cattle.
As quick as he wished to be, he spent considerable time cutting out the particular animals he wanted. His rope sailed through the air and brought one such to a standstill. Down she went with Ballou out of the saddle and running over to tie her feet. Collecting a few pieces of grass and limbs, he lit a fire, heated an iron and then began a careful job of changing the existing brand to one of his own. Being a careful workman, he finished the work of the iron with a few drops of acid from the bottle in his pocket and stepped back to survey the result.
If anybody can spot
