His Chinese friends held up their hands in dismay when he broached the subject. To the mountains where the Chhi-hoan lived! Did Kai Bok-su not know that every man of them was a practised head-hunter, and that behind every rock and tree and in the darkness of the forests they lay in wait for any one who went beyond the settled districts? Yes, Kai Bok-su knew all that, but he could not quite explain that it was just that which made the thought of a visit to them seem so alluring, just that which made him so anxious to tell them of Jesus Christ, who wished all men to live as brothers. A Hoa and a few others who had caught the spirit of the true soldier of the cross understood. For they had learned that one who follows Jesus must be ready to dare anything, death included, to carry the news of his salvation to the dark corners of the world. But the days were so filled with preaching, teaching, and touring, that for some time Mackay had no opportunity for a trip into the head-hunters' territory. And then one day, quite unexpectedly, his chance came. There sailed into Tamsui harbor, one hot afternoon, a British man-of-war, named The Dwarf. Captain Bax from this vessel visited Tamsui, and expressed a desire to see something of the life of the savages in the mountains. This was Mackay's opportunity, and in spite of protests from his friends he offered to accompany the captain. So together they started off, the sailor-soldier of England and the soldier of the cross, each with the same place in view but each with a very different object. It took three days journey from Tamsui across rice-fields and up hillsides to reach even the foot of the mountains. Here there lived a village of natives, closely related to the savages. But they were not given to head-hunting and were quite friendly with the people about them. Mackay had met some of these people on a former trip inland, and now he and Captain Bax hired their chief and a party of his men to guide them up into savage territory. The travelers slept that night in the village, and before dawn were up and ready to start on their dangerous undertaking. Before them in the gray dawn rose hill upon hill, each loftier than the last, till they melted into the mountains, the territory of the dreaded head-hunters. They started off on a steady tramp, up hills, down valleys, and across streams, until at last they came to the foot of the first mountain.
