I was sitting outside the maloca writing my observations in the note-book which I always carried in my hunting-coat, when two young hunters hurried toward the Chief, who was reclining in the shade of a banana-tree near the other end of the large house. It was early afternoon, when most of the men of the Mangeromas were off hunting in the near-by forests, while the women and children attended to various duties around the village. Probably not more than eight or ten men remained about the maloca.

I had recovered from my sickness and was not entirely devoid of a desire for excitement - the best tonic of the explorer. The two young hunters with bows and arrows halted before the Chief. They were gesticulating wildly; and although I could not understand what they were talking about, I judged from the frown of the Chief that something serious was the matter.

He arose with unusual agility for a man of his size, and shouted something toward the opening of the maloca, whence the men were soon seen coming with leaps and bounds. Anticipating trouble, I also ran over to the Chief, and, in my defective Mangeroma lingo, inquired the cause of the excitement. He did not answer me, but, in a greater state of agitation than I had previously observed in him, he gave orders to his men. He called the "wireless" operator and commanded him to bring out his precious apparatus. This was soon fastened to the gunwales of the canoe where I had seen it used before, on my trip to the neighbouring tribe, and soon the same powerful, xylophonic sounds vibrated through the forest. It was his intention to summon the hunters that were still roaming around the vicinity, by this "C.Q.D." message. The message I could not interpret nor repeat, although it was not nearly as complex as the one I had learned before. After a while, the men came streaming into the maloca from all directions, with anxiety darkening their faces. I had now my first inkling of what was the cause of the commotion, and it did not take me long to understand that we were in danger from some Peruvian caboclos. The two young men who had brought the news to the Chief had spied a detachment of Peruvian half-breeds as they were camping in our old tambo No. 6, the one we had built on our sixth day out from Floresta. There were about a score of them, all ugly caboclos, or half-breed caucheros, hunting rubber and no doubt out also for prey in the shape of young Mangeroma girls, as was their custom. The traps set by the Indians, as described in a previous chapter, would be of no avail in this case, as the number of Peruvians was greater than in any previous experience.

The enemy had been observed more than ten miles off, in an easterly direction, when our two hunters were on the trail of a large herd of peccaries, or wild boars, they had sighted in the early morning. The Peruvians were believed to be heading for the maloca of the Mangeromas, as there were no other settlements in this region excepting the up-creek tribe, but this numbered at least five hundred souls, and would be no easy prey for them.

I now had a remarkable opportunity to watch the war preparations of these savage, cannibal people, my friends, the Mangeromas. Their army consisted of twelve able-bodied men, all fine muscular fellows, about five feet ten in height, and bearing an array of vicious-looking weapons such as few white men have seen. First of all were three club-men, armed with strong, slender clubs, of hard and extremely tough Caripari wood. The handle, which was very slim, was provided with a knob at the end to prevent the club from slipping out of the hand when in action. The heavy end was furnished with six bicuspid teeth of the black jaguar, embedded in the wood and projecting about two inches beyond the surface. The club had a total length of five feet and weighed about eight pounds. The second division of the wild-looking band consisted of three spear-men, each provided with the three-pronged spears, a horrible weapon which always proves fatal in the hands of these savages. It is a long straight shaft of Caripari wood, about one inch in thickness, divided into three parts at the end, each division being tipped with a barbed bone of the sting-ray. These bones, about three and a half inches long, were smeared with wourahli poison, and thus rendered absolutely fatal even when inflicting only a superficial wound. Each man carried two of these spears, the points being protected by grass-sheaths. The third division was composed of three bow-and-arrow men, the youngest men in the tribe, boys of sixteen and seventeen. They were armed with bows of great length, from six to seven feet, and each bore, at his left side, a quiver, containing a dozen big-game arrows fully five feet long. These arrows, as far as I could ascertain, were not poisoned, but their shock-giving and rending powers were extraordinary. The arrow-heads were all made of the bones of the sting-ray, in themselves formidable weapons, because of the many jagged barbs that prevent extraction from a wound except by the use of great force, resulting in ugly laceration.
