It is a valley of death now, parched and desolate, a waste of white sand—the dry bone dust of the cycles. But then, when the lava came surging and boiling and flaming across the plain, not a thin stream, but a wide, irresistible current, there was life; there was a city—one city at least. It is there now, under the mass of sharp, gray, porous rock; how much of it no one knows. But it is there, and it has given up its unavailing hints of a life which may have been older than that of Herculaneum and Pompeii, and is as much more safely hidden from the research of the inquiring day as its walls are more hopelessly buried beneath the ironlike stone than are those of the cisalpine cities beneath their ashen drift.

And the great river of rock is there, too, frozen upon the land like some devouring monster changed by a Gorgon head into lifeless stone. It is a formidable barrier across the hardly less formidable bad lands. It can be crossed in places where it is narrowest, not quite a mile in width, that is. But horses slip and clamber, and men cut through the leather of their heaviest shoes.

If the sea, whipping in huge waves against the fury of a typhoon, were to become on the instant rocks, it would be as this. There are heights and crevasses, hills and gulches, crests and hollows, little caves and crannies, where quail and snakes and cotton-tails and jack-rabbits, lizards and coyotes, creatures of desolation and the barrens, hide and scamper in and out. It is an impregnable stronghold, not for armies, because they could not find shelter, but for savages that can scatter like the quail themselves, and writhe on their bellies into the coyotes' own holes.

And so the hostiles took shelter there from the cavalry that had pursued them hard across the open all night, and gave battle after the manner of their kind. It was a very desultory sort of a skirmish, for the troops did not venture into the traps beyond the very edge, and the Indians were simply on the defensive. It was not only desultory, it promised to be unavailing, a waste of time and of ammunition.

The Chiricahuas might stay there and fire at intervals as long as they listed, killing a few men perhaps. And then they might retreat quite safely, putting the barrier between themselves and the pursuers. Obviously there were only two courses wherein lay any wisdom,—to retreat, or to cut off their retreat. Landor said so to the major in command.

"And how, may I ask, would you suggest cutting off their retreat?" the major inquired a little sharply. His temper was not improved by the heat and by twelve hours in the saddle.

It was certainly not apparent, on the face of it, how the thing was to be done, but the captain explained. "I've been stationed here, you know, and I know the roads. We are about a half a mile or more from where the Stanton road to the railway crosses the lava. It is narrow and rough, and about from three-quarters of a mile to a mile wide, but cavalry can go over it without any trouble. I can take my troop over, and then the Indians will be hemmed in between us. We might capture the whole band."

The major offered the objection that it would be foolhardy, that it would be cutting through the enemy by file. "They'll pick you off, and you'll be absolutely at their mercy," he remonstrated. "No, I can't hear of it."

"Suppose you let me call for volunteers," suggested Landor. He was sure of his own men, down to the last recruit.
