It is mid-day, as filing up the pass, they reach the higher level of the Llano. Not many moments do they remain there; only long enough for the rear files to get out of the gorge, when those in front move forward across the plain, guided by the two best trackers in Texas, Nat Cully and Walt Wilder.

At first there is no following of a trail, since there is none visible. Wind, rain, and drifted dust have obliterated every mark made by the returning soldiers. Not a sign is left to show the pursuers the path Uraga’s troop has taken.

They know it should be westward, and strike out without waiting to look for tracks.

For the first ten or twelve miles they ride at a rapid rate, often going in a gallop. Their horses, rested and fresh, enable them to do so. They are only stayed in their pace by the necessity of keeping a straight course—not so easy upon a treeless plain, when the sun is not visible in the sky. Unluckily for them, the day is cloudy, which renders it more difficult. Still, with the twin buttes behind—so long as these are in sight they keep their course with certainty; then, as their summits sink below the level of the plain, another landmark looms up ahead, well known by Walt Wilder and Hamersley. It is the black-jack grove where, two days before, they made their midday meal.

The Rangers ride towards it, with the intention also to make a short halt there and snatch a scrap from their haversacks.

When upon its edge, before entering among the trees, they see that which decides them to stay even less time than intended—the hoof-prints of half a hundred horses!

Going inside the copse, they observe other signs that speak of an encampment. Reading these with care, they can tell that it has not long been broken up. The ashes of the bivouac fires are scarce cold, while the hoof-marks of the horses show fresh on the desert dust, for the time converted into mud. Wilder and Cully declare that but one day can have passed since the lancers parted from the spot; for there is no question as to who have been bivouacking among the black-jacks.

A day—only a day! It will take full five before the soldiers can cross the Sierras and enter the valley of the Del Norte. There may still be a chance of overtaking them. All the likelier, since, cumbered with their captives, and not knowing they are pursued, they may be proceeding at a leisurely pace.

Cheered by this hope, and freshly stimulated, the Texans do not even dismount, but, spurring forth upon the plain, again ride rapidly on, munching a mouthful as they go.

They are no longer delayed by any doubt as to course. The trail of the lancer troop is now easily discernible, made since the storm passed over. Any one of the Rangers could follow it in a fast gallop.
