Every hour of the day and often in the night, letters came from all parts of the country to Dr. Mackay. They were brought by runners who came at great peril of their lives, and were sent by the poor Christians. Each letter told the same tale; the lives and property of all the converts were in grave danger if the enemy did not leave. And they all asked Kai Bok-su to do something to help them.

Now Kai Bok-su was a man with great power and influence both in Formosa and in his far-off Canada, but he had no means of bringing that power to bear on the French. And indeed his own life was in as great danger as any one's.

He wrote to the Christians comforting them and enthusing them with his own spirit. He bade them all be brave, and no matter what came, danger or torture or death itself, they must be true to Jesus Christ. He went about his work in the college or hospital just as usual, though he knew that any day the angry mob from the town below might come raging up to destroy and kill.

The French had entered Kelung harbor and the danger was growing more serious every day when Mackay found it necessary to go to Palm Island, a pretty islet in the mouth of the Kelung river. It was almost courting death to go, but he had been sent for, and he went. He found the place right under the French guns and in the midst of raging Chinese. Some of the faithful students were there, and they were overcome with joy and hope at the sight of him. He gathered them about him in a mission house for prayer and a word of encouragement. Outside the Chinese soldiers paraded up and down. Sometimes indeed they would burst into the room and threaten the inmates with violence should the French fire. Kai Bok-su went on quietly talking to his students. He urged them to be faithful and reminded them of what their Master suffered at the hands of a mob for their sake. But, in spite of their brave spirits, the little company could not help listening for the boom of the French guns. It was fully expected that the enemy would soon fire, and when they did, the Christians well knew there would be little chance for them to escape.

But God had prepared a way out of the difficulty. The meeting was scarcely over when a messenger came in, asking for the missionary. A Christian on the mainland was very ill and wanted Kai Bok-su to visit him. Mackay with his students left the island at once and went to the home of the sick man.

They had been gone but a short time when the thunder of the French cannon broke over the harbor. The guns from the Chinese fort answered, and had the missionary been on Palm Island he and his converts would surely have been killed.

The Chinese were no match for the French gunners. The bombardment destroyed the fort and killed every soldier who did not manage to get away. A great shell crashed into the magazine of the fort, and the explosion hurled masses of the concrete walls an incredible distance. The city about the fort was completely deserted, for the people fled at the first sound of the guns.

As soon as the firing was over, the rabble broke loose and a perfect reign of terror prevailed. The mob carried black flags and swept over town and country, plundering and murdering. The Christians were of course the first object of attack, and to tear down a church was the mob's fiercest joy. Seven of the most beautiful chapels were completely destroyed and many others injured.

In the town of Toa-liong-pong was the home of Koa Kau, one of Kai Bok-su's most devoted students. Here was a lovely chapel built at great expense. The crowd tore it to pieces from roof to foundation. Then, out of the bricks of the ruin they erected a huge pile, eight feet high; they plastered it over with mud, and on the face of it, next the highway where every one might see it, they wrote in large Chinese characters:

MACKAY, THE BLACK-BEARDED BARBARIAN,
LIES HERE. HIS WORK IS ENDED.
