retreat in case he heard one. Tango knew just as well as Mary V when they were in snake country. He had gone so far as to argue the point of climbing that ridge, but as usual Mary V's argument was stronger than Tango's, and he had yielded with an injured air that was quite lost upon his rider. Mary V was thinking of something else.
They reached the top without having seen a single snake. Tango seemed somewhat surprised at this, but Mary V was not. Mary V thought it was too hot even for rattlesnakes, and as for the dearth of lizards—well she supposed the snakes had eaten them all. She had let Tango stop often to breathe, and whenever he did so she had looked south, scanning as much of the lower level as she could see, which was not the proper way to go about hunting snake dens, I assure you. But at the top she permitted Tango to walk into the shade of a boulder that radiated heat like a stove but was still preferable to the blistering sunlight, and there she left him while she walked a little nearer the edge of the rimrock that topped the ridge on its southern side.
Once more she scanned the sweltering expanse of sagebrush, scant grass, many rock patches and much sand. She saw a rider moving along a shallow watercourse, and immediately she focused her glasses upon him. She gave an ejaculation of surprise when the powerful lenses annihilated nine tenths of the distance between them. One would judge from her manner and her tone that, while she had not been surprised to see a rider, that rider's identity was wholly unexpected.
She watched him until, having reached a certain place where a group of cottonwoods shaded the gully, he stopped and dismounted to fuss with his cinches. Mary V could not be sure whether he was merely killing time, or whether he really needed to tighten the saddle; but when another rider appeared suddenly from the eastward, she did know that the first rider showed no symptoms of surprise.
She did not know the second arrival at the cottonwoods. She could see that he was Mexican, and that was all. The two talked together with much gesturing on the part of the Mexican, and sundry affirmative nods on the part of the first rider. The Mexican frequently waved a hand toward the south—toward Sinkhole Camp, perhaps. They seemed to be in a hurry, Mary V thought. They did not tarry more than five minutes before they parted, the Mexican riding back toward the east, the first rider returning westward. He had come cautiously, at an easy pace. He went back riding at a long lope, as though time was precious to him.
Mary V watched until she saw him emerge out of that hollow and duck into another which led toward the northwest and, if he followed it, would bring him out near the head of Dry Gulch, which was several miles nearer the Rolling R home ranch than was the ridge where she stood. When he had gone, she turned again to see where the Mexican was going. The Mexican, she discovered, was going east as fast as his horse could carry him without dropping dead in that heat; and he, also, was keeping to the hollows.
"Here's a pretty howdy-do!" said Mary V to the palpitating atmosphere. "I'm just going to tell dad about Tex sneaking away down here to meet Mexicans and things on the sly! I never did like that Tex. I don't like his eyes. You can't see into them at all. I'll bet they're framing up something on Johnny Jewel—they were pointing right toward his camp. There's no telling what they're up to! I'm going right and tell dad—"
But she couldn't. Mary V knew she couldn't. In the first place, her dad would ask her what she was doing on Black Ridge, which was far beyond her permitted range of activities. Her dad would foolishly maintain that she could glimpse all the desert necessary without going that far from the ranch. In the second place, he would probably tell her that he was paying Tex to ride the range and, if he met a Mexican, it was his business to send that same Mexican back where he came from. In the third place, he would think she was riding over there for a reason which was untrue and very, very unjust. And he wouldn't fire Tex, because Tex was a good "hand" and hands were hard to find. He would simply make her promise to stay at home.
"He'd say it was perfectly all right for Tex—and perfectly all wrong for me. Dad's tremendously pin-headed where I am concerned. So I suppose I'll just have to say nothing, and ride all that long way in the hot sun to make sure that horrid Johnny Jewel is not being murdered or something. It doesn't, of course, concern me personally at all—but dad is so short-handed this summer. And he actually threatened that he couldn't afford me a new car this winter if wages go up or horses go down, or anything happens that doesn't just please him. And I suppose Johnny Jewel has his uses, in the general scheme of dad's business, so even if he is a mean, conceited little shrimp personally, I'll have to go and make sure he isn't killed, because it would be just like dad to call that bad luck, and grouch around and not get me the car."
Mary V had barely reached this goal of personal unconcern for anything but her own private interests, when Tango began to manifest certain violent symptoms of having seen or heard something very disagreeable. Mary V had to take some long, boyish steps in order to snatch his reins before he bolted and left her afoot, which would have been a real calamity. But she caught him, scolded him shrewishly and slapped his cheek until he backed from her wall-eyed, and then she mounted him and went clattering down off the ridge without having seen any snake dens at all. Doubtless the boys had lied to her, as usual.
To Sinkhole Camp was a long way, much longer than it had looked from the top of Black Ridge. Mary V, her face red with heat, hurried on and on, wishing over and over that she had never started at all, but lacking the resolution to turn back. Yet she was considered a very resolute young woman by those who knew her most intimately.
Perversely she blamed Johnny Jewel for putting her to all this trouble and discomfort, and for interrupting her in her work of getting Desert Glimpses. She repeatedly told herself that he would not even have the common human instinct to feel grateful toward her for riding away down there to see if he were murdered.
She was right in that conjecture, at least. When she rode up to the squat adobe cabin, somewhere near noon, she found Johnny Jewel stretched morosely on his back, staring up at the low roof and thinking the gloomiest thoughts which a lonesome young man of twenty-one or two may conjure from a fit of the blues. That he was not murdered or even menaced with any danger seemed to Mary V a personal grievance against herself after that terrifically hot ride.
Johnny turned a gloomy glance upon her when she walked in and sat down limply on the one chair in the cabin; but he did not show any keen pleasure in her presence, nor any gratitude.
"Well! You're still alive, then!" she said rather crossly.
"I guess I am. Why?" Johnny, his meditations disturbed by her coming, rose languidly and sat upon the side of his bunk, slouched forward with his arms resting across his strong young legs and his glance inclined to the floor.
"Oh, nothing." Mary V took off her hat, but she was too fagged to fan herself with it. Her one emotion, at that moment, was an overwhelming regret that she had come. If Johnny Jewel had the nerve to think that she wanted to see him—
"You must love the sun," Johnny observed apathetically. "Lizards, even, have got sense enough to stay in the shade such weather as this." He rumpled his hair to let the faint breeze in to his scalp, and looked at her. "You're red as a pickled beet at a picnic," he told her ungraciously.
Mary V pulled together her lagging wits, marshaled her fighting forces, and flaunted a war banner in the shape of a smile that was demure.
"Well, one must expect to make some sacrifices when one is working in a good cause," she replied amiably, and paused.
"Yeh?" Johnny's eyes lost a little of their dullness. It is possible that he recognized that war banner of hers. "One didn't expect to see one down here—on a good cause."
"No? Well, you do see one, nevertheless. One is at work on an exhibit for one's school, you see. Each of us girls was assigned a subject for vacation work. Mine is 'Desert Glimpses'—a collection of pictures, curios and so on, representing points of interest in the desert country. I've a horned toad at home, and a blue-tailed lizard, and some pictures of jack rabbits, with their ears attached to the frame, and quite a few rattlesnake rattles. So to-day," she smiled again at him, "I rode down here to take a picture of you!"
"Thanks," said Johnny, apparently unmoved. "I didn't know I was a point of interest in your eyes; but seeing I am, I'm willing the girls should have a picture of me framed. If you'll
