The strong, clear picture given to her by the sunlight was one that would remain with her until memory itself should fade and grow dark. The ground was not as she had supposed, level and free from obstacles; they were winding their way along a rock-strewn valley and mounting fast. The pack-mules, twenty or more of them, with lowered heads climbed patiently each in the footsteps of another; at intervals rode the eight mounted men; and Dyke now pushing ahead, riding alone, seemed an enormous figure in his huge mushroom hat and hung round with wallets. He was happy and joyous, beginning to sing scraps of song; so that his music floated back to them pleasantly, and after a while caught the riders with its pleasant contagion and made them sing too. But queerly there mingled with the song or its pauses that other music of the bell, which she had fancied an evocation of tricked senses. It was with them still, faintly chiming, gently tinkling, as if a cadence of the march itself.

Manuel Balda, most attentive of guardians, riding by her bridle since Dyke had left her, explained the matter. Pointing to a small grey pony that plodded unladen in advance of the pack-mules, he told her that this little mare was the “madrina” or adopted mother of the troop. With the bell strapped round her neck, she and not any of the riders was really leading the mules. Wherever she went they would follow. If they strayed, the sound of the madrina’s bell would bring them back. They would be miserable, despairing, if they lost it.

Emmie liked Manuel better to-day; indeed that first faint distrust or questioning doubt of him recurred no more to her contented mind. Every hour he proved himself more useful and valuable. Moreover, though no less respectful, he was less ceremonious now that they had entered the wilderness and left the beaten track far behind them. He laughed and joked, told her travellers’ tales, and showed her how he could swing down from his saddle and pick up a stone from the ground as he cantered past.

He told her, amongst other things, that there had been much talk last night at the inn concerning Ruy Chaves, the notorious bandit of the mountains. This bloodthirsty ruffian and his gang were still at large—a disgrace, as Manuel opined, both to the Chilian and the Argentine frontier forces—and quite recently they had seized a pack train rich with merchandise and murdered the inoffensive merchants and muleteers. “It is a shame, Missis.” And amplifying his narrative, Manuel related how travellers in small parties feared to move freely because of Chaves, how the poor defenceless little innkeepers were forced to pay him tribute; and how, impelled by the cruel humour that is traditionally common with such pirate-dogs, he “teased” as well as killed his victims—for instance, making them dance and caper on the edge of precipices, till to the prick of his knife they jumped into eternity.

Miss Verinder wished to know if Mr. Dyke had heard this talk about Ruy Chaves the bandit; and Manuel said yes, he had heard it all, and he “had laughed and done so.” And Manuel snapped his fingers, and then looked very fierce; implying that bandits would be wise to give him, Manuel, as well as his friend and patron Don Antonio, the widest of wide berths. “You not fear, Missis?”

And he laughed gaily, assuring her that bandit gangs worked frequented highways, and never came up here where there was nothing to prey upon; and that in any circumstances they would not for a moment dream of attacking a strong armed party such as this. Missis need not fear it or anything else. Starvation, thirst, snow—those were the true enemies. And there was much food on the mules, there would be water nearly all the way, the full summer season was propitious.

“So we hope Don Antonio will find what he seeks. It is treasure, is it not, Missis? Ah, ha”; and Manuel laughed cheerfully. “You must not say me. But he—Don Antonio—has allow the boys to guess. You can see in the boys’ eyes—so happy and hoping. The Indians most. They will not grow tired—our Indians—now they know what they hunt.”

“Which are the Indians?” asked Emmie. “They all seem just alike.”

In fact, except to a practised eye, there was little that could enable one to distinguish between the descendants of the men who had once owned the land and the descendants of the men who had stolen it from them. Spanish or Indian, these muleteers were dressed in the same manner, spoke the same tongue, and had the same wild cut-throat look except when they were singing or laughing. There was not even a difference of complexion visible. But, as Manuel said, these good boys, although of unadulterated Indian blood, had long enjoyed the advantages of civilization. They were gauchos; they had abandoned the savage hills for the prosperous plains. Yet they could be more useful here than anybody else, because this was their ancient home; they would be able to work well in the air that their ancestors had breathed.

Dyke, far ahead, had reached the top of the valley, and, dismounted, was leading his mule up a steep ridge. This was the first taste of difficulty. They climbed the ridge, scrambled down a long slope, and emerged into another valley, more rock-strewn, more chaotic than the first, with a deep-cut stream running a serpentine course towards them.
