"Keep your men together, Sergeant," said Thurstane. "I must get those Mexicans to work."

He trotted deliberately to the other end of the train, ordering each driver as he passed to move up abreast of the leading wagon, directing the first to the right, the second to the left, and so on. The result of this movement would of course be to bring the train into a compact mass and render it more defensible. The Indians no sooner perceived the advance than they divined its object and made an effort to prevent it. Thurstane had scarcely reached the centre of the line of vehicles when a score or so of yelling horsemen made a caracoling, prancing charge upon him, accompanying it with a flight of arrows. Our young hero presented his revolver, but they apparently knew the short range of the weapon, and came plunging, curveting onward. Matters were growing serious, for an arrow already stuck in his saddle, and another had passed through his hat. Suddenly there was a bang, bang of firearms, and two of the savages went down.

Meyer had observed the danger of his officer, and had ordered Kelly to fire, blazing away too himself. There was a headlong, hasty scramble to carry off the fallen warriors, and then the assailants swept back to a point beyond accurate musket shot. Thurstane reached the rear of the train unhurt, and found the six Mexican cattle-drivers there in a group, pointing their rifles at such Indians as made a show of charging, but otherwise doing nothing which resembled fighting. They were obviously panic-stricken, one or two of them being of an ashy-yellow, their nearest possible approach to pallor. There, too, was Coronado, looking not exactly scared, but irresolute and helpless.

"What does this mean?" Thurstane stormed in Spanish. "Why don't you shoot the devils?"

"We are reserving our fire," stammered Coronado, half alarmed, half ashamed.

Thurstane swore briefly, energetically, and to the point. "Damned pretty fighting!" he went on. "If we had reserved our fire, we should all have been lanced by this time. Let drive!"

The cattle-drivers carried short rifles, of the then United States regulation pattern, which old Garcia had somehow contrived to pick up during the war perhaps buying them of drunken soldiers. Supported by Thurstane's pugnacious presence and hurried up by his vehement orders, they began to fire. They were shaky; didn't aim very well; hardly aimed at all, in fact; blazed away at extraordinary elevations; behaved as men do who have become demoralized. However, as the pieces had a range of several hundred yards, the small bullets hissed venomously over the heads of the Indians, and one of them, by pure accident, brought down a horse. There was an immediate scattering, a multitudinous glinting of hoofs through the light dust of the plain, and then a rally in prancing groups, at a safe distance.

"Hurrah!" shouted Thurstane, cheering the Mexicans. "That's very well. You see how easy it is. Now don't let them sneak up again; and at the same time don't waste powder."

Then turning to one who was near him, and who had just reloaded, he said in a calm, strong, encouraging tone—that voice of the thoroughly good officer which comes to the help of the shaken soldier like a reinforcement—"Now, my lad, steadily. Pick out your man; take your time and aim sure. Do you see him?"

"Si, señor," replied the herdsman. His coolness restored by this steady utterance and these plain, common-sense directions, he selected a warrior in helmet-shaped cap, blue shirt, and long boots, brought his rifle slowly to a level, took sight, and fired. The Indian bent forward, caught the mane of his plunging pony, hung there for a second or two, and then rolled to the ground, amid a yell of surprise and dismay from his comrades. There was a hasty rush to secure the body, and then another sweep backward of the loose array.
