It looked as if Fred Ashman had gained a double victory over the giant Ziffak, and his second triumph was infinitely greater than his first.

His heart thrilled at the thought that this formidable antagonist had been so suddenly transformed into a friend; and yet he could not entirely free himself from a certain misgiving, as the two walked side by side along the Xingu. Recalling the dexterity of the native—all the more wonderful because of his bulk—he reflected, that it was the easiest thing in the world for him to turn like a flash and pierce him with his poisoned javelin before the slightest defence could be made.

It was this thought which led him stealthily to place his hand on the butt of the revolver at his hip, prepared to whip it out and fire as quickly as he knew how. At the same time he edged away from him, so as to maintain considerable space between their bodies.

Ziffak suddenly changed his javelin from his right to his left hand, the movement sending a shock of fear through the American, who the next moment blushed from shame, for it was manifest that the shrewd savage suspected the timidity of his new friend, and shifted the frightful weapon to the side furthest from him to relieve any misgiving on his part.

The conversation continued as they walked, the native showing a surprising willingness to answer all questions.

Ashman gathered from what was told him that the Murhapas were a tribe numbering fully a thousand men, women and children; that they occupied a village or town on the right bank of the Xingu about twenty miles above the rapids, where the incidents already recorded occurred, and that they were far superior in intelligence, physical development and prowess to any other tribes in the Matto Grosso.

It was about five years before that the two white men, Waggaman and Burkhardt, suddenly made their appearance at the towns. The fact that they did not come up the Xingu, but from the forest to the south, strengthened Ashman's suspicion that they were criminals who had managed to escape from the Brazilian diamond mines, though it was a mystery how they had secured the two rifles which they brought with them. They had no revolvers, and their guns were not of the repeating pattern. When their ammunition gave out, one of them made a journey of several days' duration into the wilderness, invariably bringing back a supply which lasted a long time.

Such weapons were entirely unknown to the Murhapas, who had never heard of anything of the kind. The exploits of the owners caused the natives to look upon them with awe. They were soon established on the best of terms with their new associates, who allowed them to do as they chose in everything.

It is not to be supposed that Ashman gathered all the information given in this chapter, during his brief walk with Ziffak. Indeed, that which has already been stated was obtained only in part during the memorable interview; but it may be as well to add other facts which afterwards came to the knowledge of him and the explorers, since it is necessary to know them in order to understand the strange series of incidents and adventures in which they became speedily involved.

The Murhapa tribe was ruled by King Haffgo, whose complexion was almost as fair as that of a European. He had fifty wives, but only one child, whose mother was dead. This child was a daughter, Ariel, of surpassing beauty and loveliness, the pride of her grim father and adored by all his subjects. From Waggaman and Burkhardt she had acquired a knowledge of the English tongue, which Ziffak declared was superior to his own. Both of these men had sought in turn to win her as his wife, and the king was not unwilling, because of the awe in which he held them; but Ariel would not agree to mate herself with either, though she once intimated that when she became older she might listen favorably to the suit of Waggaman, whose appearance and manner were less repulsive than those of his comrade.

The first duty the guests took upon themselves was to impress King Haffgo and his subjects that all white men except themselves were their deadliest enemies, and, if any of them were allowed to visit the village, they would assuredly bring others who would cause the utter destruction of the inhabitants.

Three years before, a party of six white explorers ascended the Xingu, and suddenly presented themselves to the Murhapas, without previous announcement or knowledge. Despite their professions of friendship, and a most valiant defence, they were set upon and slain the same hour they appeared among the fierce people.

Ariel, the daughter of the king, was but a child, at that time, just entering her teens. She did not know of the cruel massacre until it was over, when she surprised all by expressing her sorrow and declaring that a great wrong had been done the strangers. From that time forward, those who studied her closely saw that she had formed a strong distrust, if not dislike, of Waggaman and Burkhardt, though, seeing the high favor in which they were held in court, she sought to veil her true feelings.

Ziffak was a younger brother of the king, and bore the title of head-chieftain. He was next in authority and power, and, because of his immense size and prowess, led all expeditions against their enemies, none of whom was held in fear. Occasionally, he head............
