The quick puffing of the steam launch _Miro_ was the only sound to break the stillness of the mysterious Aivai[36] River. On the launch were three white people--two men and a woman. They were the first who had ever broken the silence of that stream. They gazed out under the morning sun along the dead level of the Purari[37] delta, for they had left behind them the rolling breakers of the Gulf of Papua in order to explore this dark river. Away to the south rolled the blue waters between this vast island of New Guinea and Northern Australia. They saw on either bank the wild tangle of twisted mangroves with their roots higher than a man, twined together like writhing serpents. They peered through the thick bush with its green leaves drooping down to the very water's edge. But mostly they looked ahead over the bow of the boat along the green-brown water that lay ahead of them, dappled with sunlight under the trees. For they were facing an unknown district where savage Papuans lived--as wild as hawks. They did not know what adventure might meet them at the next bend of the river. "Splendid! Splendid!" cried one of the white men, a bearded giant whose flashing eyes and mass of brown hair gave him the look of a lion. "We will make it the white woman's peace. Bravo!" And he turned to Mrs. Abel, whose face lit up with pleasure at his happy excitement. "No white man has even seen the people of Iala,"[38] said Tamate--for that was the native name given to James Chalmers, the Scottish boy who had now gone out to far-off Papua as a missionary.[39] "Iko there"--and he pointed to a stalwart Papuan who stood by the funnel--"is the only one of us who has seen them and can speak their tongue. "It is dangerous for your wife to go among these people," he went on, turning to Mr. Abel, "but she will help us more than anything else possibly can to make friends." And Mr. Abel nodded, for he knew that when the Papuans mean to fight they send their women and children away; and that when they saw Mrs. Abel they would believe that the white people came as friends and not enemies. As the steamer carried this scouting party against the swift current up the river toward Iala, Tamate wanted to find how far up the river the village lay. So he beckoned Iko to him. Tamate did not know a word of the dialect which Iko spoke, but he had with him an old wrinkled Papuan, who knew Iko's language, and who looked out with worshipping eyes at the great white man who was his friend. So Tamate, wishing to ask Iko how far away the village of Iala was, spoke first to old Vaaburi,[40] and then Vaaburi asked Iko. Iko stretched out his dark forefinger, and made them understand that that finger meant the length of their journey to Iala. Then with his other hand he touched his forefinger under the second joint to show how far they had travelled on their journey--not a third of the distance.
