An enemy's battle-ships off the coast of Formosa! During all the spring rumors of trouble had been coming across the channel from the mainland. France (*) and China had been quarreling over a boundaryline in Tongking. The affair had been settled but not in a way that pleased France. So, without even waiting to declare war, she sent a fleet to the China Sea and bombarded some of her enemy's ports. Formosa, of course, came in for her share of the trouble, and it was early in the summer that the French battle-ships appeared. They hove in sight, sailing down the Formosa Channel or Strait one hot day, and instantly all Formosa was in an uproar of alarm and rage. The rage was greater than the alarm, for China cordially despised all peoples beyond her own border, and felt that the barbarians would probably be too feeble to do them any harm. But that the barbarians should dare to approach their coast with a war-vessel! That was a terrible insult, and the fierce indignation of the people knew no bounds. Their rage broke out against all foreigners. They did not distinguish between the missionary from British soil and the French soldiers on their enemy's vessels. They were all barbarians alike, the Chinese declared, and as such were the deadly foe of China. This Kai Bok-su was in league with the French, and the native Christians all over Formosa were in league with him, and all deserved death! * War in 1844. So hard days came for the Christians of north Formosa. Wherever there was a house containing converts, there was riot and disorder. For bands of enraged heathen, armed with knives and swords, would parade the streets about them and threaten all with a violent death the moment the French fired a shot. In some places near the coast the Christian people dared not leave their houses, and whenever they sent out their children to buy food, often a heathen neighbor would catch them, brandish knives over the terrified little ones' heads and declare they would all be cut to pieces when the barbarian ships came into port. 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.
