They understood, and also they guessed from the expression of his face that he sought Tarzan from motives of affection rather than the reverse, but of this Om-at wished to make sure. He pointed to the stranger's knife, and repeating Tarzan's name, seized Ta-den and pretended to stab him, immediately turning questioningly toward the stranger. The latter shook his head vehemently and then first placing a hand above his heart he raised his palm in the symbol of peace. "He is a friend of Tarzan-jad-guru," exclaimed Ta-den. "Either a friend or a great liar," replied Om-at. "Tarzan," continued the stranger, "you know him? He lives? O God, if I could only speak your language." And again reverting to sign language he sought to ascertain where Tarzan was. He would pronounce the name and point in different directions, in the cave, down into the gorge, back toward the mountains, or out upon the valley below, and each time he would raise his brows questioningly and voice the universal "eh?" of interrogation which they could not fail to understand. But always Om-at shook his head and spread his palms in a gesture which indicated that while he understood the question he was ignorant as to the whereabouts of the ape-man, and then the black chief attempted as best he might to explain to the stranger what he knew of the whereabouts of Tarzan. He called the newcomer Jar-don, which in the language of Pal-ul-don means "stranger," and he pointed to the sun and said _as_. This he repeated several times and then he held up one hand with the fingers outspread and touching them one by one, including the thumb, repeated the word adenen until the stranger understood that he meant five. Again he pointed to the sun and describing an arc with his forefinger starting at the eastern horizon and terminating at the western, he repeated again the words as adenen. It was plain to the stranger that the words meant that the sun had crossed the heavens five times. In other words, five days had passed. Om-at then pointed to the cave where they stood, pronouncing Tarzan's name and imitating a walking man with the first and second fingers of his right hand upon the floor of the recess, sought to show that Tarzan had walked out of the cave and climbed upward on the pegs five days before, but this was as far as the sign language would permit him to go. This far the stranger followed him and, indicating that he understood he pointed to himself and then indicating the pegs leading above announced that he would follow Tarzan. "Let us go with him," said Om-at, "for as yet we have not punished the Kor-ul-lul for killing our friend and ally." "Persuade him to wait until morning," said Ta-den, "that you may take with you many warriors and make a great raid upon the Kor-ul-lul, and this time, Om-at, do not kill your prisoners. Take as many as you can alive and from some of them we may learn the fate of Tarzan-jad-guru."
