Gale gazed abroad, knowing that as this night was the first time for him to awake to consciousness of a vague, wonderful other self, so it was one wherein he began to be aware of an encroaching presence of physical things—­the immensity of the star-studded sky, the soaring moon, the bleak, mysterious mountains, and limitless slope, and plain, and ridge, and valley.  These things in all their magnificence had not been unnoticed by him before; only now they spoke a different meaning.  A voice that he had never heard called him to see, to feel the vast hard externals of heaven and earth, all that represented the open, the free, silence and solitude and space.

Once more his thoughts, like his steps, were halted by Ladd’s actions.  The cowboy reined in his horse, listened a moment, then swung down out of the saddle.  He raised a cautioning hand to the others, then slipped into the gloom and disappeared.  Gale marked that the halt had been made in a ridged and cut-up pass between low mesas.  He could see the columns of cactus standing out black against the moon-white sky.  The horses were evidently tiring, for they showed no impatience.  Gale heard their panting breaths, and also the bark of some animal—­a dog or a coyote.  It sounded like a dog, and this led Gale to wonder if there was any house near at hand.  To the right, up under the ledges some distance away, stood two square black objects, too uniform, he thought, to be rocks.  While he was peering at them, uncertain what to think, the shrill whistle of a horse pealed out, to be followed by the rattling of hoofs on hard stone.  Then a dog barked.  At the same moment that Ladd hurriedly appeared in the road a light shone out and danced before one of the square black objects.

“Keep close an’ don’t make no noise,” he whispered, and led his horse at right angles off the road.

Gale followed, leading Mercedes’s horse.  As he turned he observed that Lash also had dismounted.

To keep closely at Ladd’s heels without brushing the cactus or stumbling over rocks and depressions was a task Gale found impossible.  After he had been stabbed several times by the bayonetlike spikes, which seemed invisible, the matter of caution became equally one of self-preservation.  Both the cowboys, Dick had observed, wore leather chaps.  It was no easy matter to lead a spirited horse through the dark, winding lanes walled by thorns.  Mercedes horse often balked and had to be coaxed and carefully guided.  Dick concluded that Ladd was making a wide detour.  The position of certain stars grown familiar during the march veered round from one side to another.  Dick saw that the travel was fast, but by no means noiseless.  The pack animals at times crashed and ripped through the narrow places.  It seemed to Gale that any one within a mile could have heard these sounds.  From the tops of knolls or ridges he looked back, trying to locate the mesas where the light had danced and the dog had barked alarm.  He could not distinguish these two rocky eminences from among many rising in the background.
