Ten miles from Tek-chham stood a little village called Geh-bai. The missionary-soldiers visited it, and to their delight found a church building ready for them. It was quite a wonderful place, capable of holding fully a thousand people without much crowding. Its roof was the boughs of the great banyan tree; its one pillar the trunk, and its walls the branches that bent down to enter the ground and take root. It made a delightful shelter from the broiling sun. And here Kai Bok-su preached. But a banyan does not give perfect shelter in all kinds of weather, so when a number of people had declared themselves followers of the Lord Jesus, a large house was rented and fitted up as a chapel, with another native pastor over it. Away over at Kelung a church was founded through a man who had carried the gospel home from one of the missionary's sermons. Here and there the hepaticas were springing up. From all sides came invitations to preach the great news of the true God, and the young missionary gave himself scarcely time to eat or sleep. He worked like a giant himself, and he inspired the same spirit in the students that accompanied him. He was like a Napoleon among his soldiers. Wherever he went they would go, even though it would surely mean abuse and might mean death. And, wherever they went, they brought such a wonderful, glad change to people's hearts that they were like slave-liberators setting captives free. The most lawless and dangerous region in all north Formosa was that surrounding the small town of Sa-kak-eng. In the mountains near by lived a band of robbers who kept the people in a constant state of dread by their terrible deeds of plunder and murder. Sometimes the frightened townspeople would help the highwaymen just to gain their good-will, and such treatment only made them bolder. Bands of them would even come down into the town and march through the streets, frightening every one into flight. They would shout and sing, and their favorite song was one that showed how little they cared for the laws of the land. You trust the mandarins, We trust the mountains. So the song went, and when the missionary heard it first he could not help confessing that after all it was a sorry job trusting the mandarins for protection. The first time he visited the place with A Hoa they were stoned and driven out. But the missionaries came back, and at last were allowed to preach. And then converts came and a church was established. The robber bands received no more assistance from the people, and were soon scattered by the officers of the law. And Sa-kak-eng was in peace because the missionary had come.
