Three horsemen were riding slowly northward along this mountain road, picking their way heedfully over its inequalities, edging nearer to the wall of rock on their left hand as they came to spots where a false step would have carried them into the abyss. To a distant observer it would have appeared as though they were moving without support on the very face of the mountain. They wore European garments, and the briefest inspection of their features would have sufficed to tell that they were Englishmen. Behind them, at some little distance, rode eight or ten bearded men of swarthy hue, whose turbans, tunics, and long boots proclaimed them as sowars of a regiment of Border cavalry. Still farther behind, in a long straggling line, came a caravan of laden mules, each in charge of a half-naked Astori. The tail of this singular procession, perhaps a mile behind the head, consisted of two native troopers like those who preceded them. It was now nearly dark. Presently the three Englishmen halted, and the eldest of them, turning in his saddle, addressed a few words in Urdu to the dafadar of the sowars behind. The riders, English and native alike, dismounted, and led their horses up a slight ascent to the left, halting again when they reached a stretch of level ground which the leader had marked as a suitable camping place. A thin rill trickled musically down at the edge of this convenient plateau, forming a small quagmire in its passage across the track, and plunging over the brink to merge in the broader stream, now obliterated by the night, hundreds of feet below. The three Englishmen tethered their horses to some young pines that bounded the level space, then sat themselves upon a neighbouring rock, lit their pipes, and looked on in silence as the dusky troopers removed their saddle-bags and stood in patient expectancy. By and by the head of the mule train appeared along the winding track. They came up one by one, and now the evening stillness was broken as the muleteers stripped their loads from the weary beasts, and with shrill and voluble chatter spread about the impedimenta of the camp. Quickly a tent was pitched, cooking pots were set up; and the Englishmen felt that comfortable glow which envelops travellers at the near prospect of supper after a long and toilsome march. The meal was almost ready when the end of the caravan arrived, and the two rearmost sowars rejoined their comrades, with no other sound than a guttural grunt of satisfaction.
