I examined the “sign.” Even to my eyes it was readable, and just as Garey had interpreted it. There were other tracks of wolves on the damp soil, but one had certainly launched himself forward, in a long leap, as though in an effort to fasten himself upon the flanks of some animal. The hoof-mark plainly showed that the steed had slipped as he sprang over the wet grass; and this had tempted the spring of the watchful pursuer.

We hurried on. Our excited feelings hindered us from causing longer than a moment. Both rangers and trappers snared my eagerness, as well as my apprehensions. Fast as the torches could be carried, we hurried on.

Shortly after parting from the mesa, there occurred a change in our favour. The lights had been carried under hats to protect them from the rain. This precaution was no longer required. The storm had passed—the shower ceasing as suddenly as it had come on; the clouds were fast driving from the face of the firmament. In five minutes more, the moon would shine forth. Already her refracted rays lightened the prairie.

We did not stay for her full beam; time was too precious. Still trusting to the torches, we hurried on.

The beautiful queen of the night kept her promise. In five minutes, her cheering orb shot out beyond the margin of the dark pall that had hitherto shrouded it; and her white disc, as if purified by the storm, shone with unwonted brightness. The ground became conspicuous almost as in day; the torches were extinguished, and we followed the trail more rapidly by the light of the moon.

Here, still in full gallop, had passed the wild-horse, and for miles beyond—still had he gone at utmost speed. Still close upon his heels had followed the ravenous and untiring wolves. Here and there were the prints of their clawed feet—the signs of their unflagging pursuit.

The roar of water sounded in our ears: it came from the direction towards which the trail was conducting us, a stream was not far distant.

We soon diminished the distance. A glassy sheet glistened under the moonlight, and towards this the trail trended in a straight line.

It was a river—a cataract was near, down which the water, freshened by the late rain, came tumbling, broken by the rocks into hummocks of white foam. Under the moonlight, it appeared like an avalanche of snow. The trappers recognised an affluent of the Rio Bravo, running from the north—from the high steppe of the Llano Estacado.

We hurried forward to its bank, and opposite the frothing rapids. The trail conducted us to this point—to the very edge of the foaming water. It led no farther. There were the hoof-marks forward to the brink, but not back. The horse had plunged into the torrent.
