For a week they labored on together, grim, watchful, expectant—then, at the break of day, they heard a distant rattle of arms, like the tearing of a cloth, and knew that the battle was on.

The great whistle at Fortuna opened with its full, bass roar, and Amigo snatched up his gun and went loping down the cañon, drawn irresistibly by the sound of conflict. Bud lingered, climbing higher and higher to get a view of the country. But his young blood clamored for action too, and soon he was mounted and gone.

The fighting was not at the American town, but down the valley by Old Fortuna, and as Hooker galloped on toward the sound of the firing he noticed that it was on the move. Already the cowardly rebels were retreating—the volunteers from Fortuna were hurrying to get closer to them, the rurales were riding to flank them; and when Bud jumped his horse up the last hill and looked down into the broad, cultivated valley he saw the dust of their flight.

Down the fenced trail that led to the lower country the mounted insurrectos were spurring in a rout; across the newly plowed fields of Aragon the men on foot were making a short cut for the hills; and all about them, like leaping grasshoppers, sprang up puffs of dust.

Now they plunged into the willow brush along the river, where it swung in against the ridge; and as their pursuers broke into the open they halted and returned the fire. The bullets struck up the dust like hailstones in front of the oncoming irregulars, a man or two in the lead went down, and they faltered. Then, as frantically as the rebels, they turned and ran for cover.

While defenders and invaders shot back and forth across the broad field, Bud put spurs to his horse and rode closer, and when he came out on another hilltop he was just in time to see the rurales come pelting in from the west, and take the revoltosos on the flank. There was a great deal of long-distance firing then, while the rebels slowly retreated, and finally, with a last defiant volley, the defenders turned back from their pursuit and marched triumphantly to Old Fortuna.

There, amid numerous vivas, Don Cipriano rolled out a cask of mescal and, after a fiery speech, invited the victors to help themselves. So they fell to drinking and carousing, and the one defender who had been wounded was bandaged and made much of, while a great crowd from the upper town looked on in awe and admiration.

At last Manuel del Rey and his rurales returned from harassing the enemy and, with several wounded prisoners in their midst, the valor-drunk Mexicans formed a riotous procession and went marching back to town. Every horse and mule was carrying double, guns were being dropped, broad hats knocked off, and ever, as they marched, they shouted:

"Viva Madero! Viva Mejico! Muerte á los revoltosos!"

It was an edifying spectacle to an American, and with the rest Bud tagged along to the plaza, where they had speeches and cheers galore and more mescal at the company's cantina. But in the midst of it, while he sat laughing on his horse by the hotel, Bud felt a gravel strike his broad hat from above and, looking furtively up, he beheld Gracia Aragon smiling down at him from the balcony.
