Two trails met and crossed near a sand-buffeted bowlder of lava stone, which was huge, grotesque and forbidding in its bulky indistinctness. The first of the trails ran north and south and was faint but plainly discernible, being beaten a trifle below the level of the desert and forming a depression which the winds alternately filled and emptied of dust; and its arrow-like directness, swerving neither to the right nor left, bespoke of the haste which urged the unfortunate traveler to have done with it as speedily as possible, since there was nothing alluring along its heat-cursed course to bid him tarry in his riding. There was yet another reason for haste, for the water holes were over fifty miles apart, and in that country water holes were more or less uncertain and doubtful as to being free from mineral poisons. On the occasions when the Apaches awoke to find that many of their young men were missing, and a proved warrior or two, this trail become weighted with possibilities, for this desert was the playground of war parties, an unlimited ante-room for the preliminaries to predatory pilgrimages; and the northern trail then partook of the nature of a huge wire over which played an alternating current, the potentials of which were the ranges at one end and the savagery and war spirit of the painted tribes at the other: and the voltage was frequently deadly. The other trail, crossing the first at right angles, led eastward to the fertile valleys of the Canadian and the Cimarron; westward it spread out like the sticks of a fan to anywhere and nowhere, gradually resolving itself into the fainter and still more faint individual paths which fed it as single strands feed a rope. It lacked the directness of its intersector because of the impenetrable chaparrals which forced it to wander hither and yon. Neither was it as plain to the eye, for preference, except in cases of urgent necessity, foreswore its saving of miles and journeyed by the more circuitous southern trail which wound beneath cottonwoods and mottes of live oak and frequently dipped beneath the waters of sluggish streams, the banks of which were fringed with willows. As a lean coyote loped past the point of intersection a moving object suddenly topped the skyline of the southern end of the sandhills to the east and sprang into sharp silhouette, paused for an instant on the edge of the range and then, plunging down into the shadows at its base, rode rapidly toward the bowlder.
