The aggrieved Chinese gathered about him, each telling the story as loud as his voice would permit. Those barbarians of the sea had come swaggering along the streets waving their big sticks. And they had dared—yes actually DARED—to hit the pet pigs belonging to every house as they passed. The poor pigs who lay sunning themselves at the door!
This was indeed a serious offense. Mackay could picture the rollicking sailor-lads gaily whacking the lazy porkers with their canes as they passed, happily unconscious of the trouble they were raising. But there was no amusement in Kai Bok-su's grave face. He spoke kindly, and soothingly, and promised that if the offenders misbehaved again he would complain to the authorities. That made it all right. Heathen though they were, they knew Kai Bok-su's promise would not be broken, and away they went quite satisfied.
One day he learned, quite by accident, a new and very useful way of helping his people. He and A Hoa and several other young men who had become Christians, went on a missionary tour to Tek-chham, a large city which he had visited once before.
On the day they left the place, Kai Boksu's preaching had drawn such crowds that the authorities of the city became afraid of him. And when the little party left, a dozen soldiers were sent to follow the dangerous barbarian and his students and see that they did not bewitch the people on the road.
The soldiers tramped along after the missionary party, and with his usual ability to make use of any situation, Mackay stepped back and chatted with his spies. He found one poor fellow in agony with the toothache. This malady was very common in north Formosa, partly owing to the habit of chewing the betel-nut. He examined the aching tooth and found it badly decayed. "There is a worm in it," the soldier said, for the Formosan doctors had taught the people this was the cause of toothache.
Mackay had no forceps, but he knew how to pull a tooth, and he was not the sort to be daunted by the lack of tools. He got a piece of hard wood, whittled it into shape and with it pried out the tooth. The relief from pain was so great that the soldier almost wept for joy and overwhelmed the tooth-puller with gratitude. And for the remainder of the journey the guards sent to spy on the missionary's doings were his warmest friends.
After this, dentistry became a part of this many-sided missionary's work. He went to a native blacksmith and had a pair of forceps hammered out of iron. It was a rather clumsy instrument, but it proved of great value, and later he sent for a complete set of the best instruments made in New York.
So with forceps in one hand and the Bible in the other, Mackay found himself doubly equipped. Every second person seemed to be suffering from toothache, and when the pain was relieved by the missionary, the patient was in a state of mind to receive his teaching kindly. The cruel methods by which the native doctors extracted teeth often caused more suffering than the toothache, and sometimes even resulted in death through blood-poisoning.
A Hoa and some of the other young converts learned from their teacher how to pull a tooth, and they, too, became experts in the art.
Whenever they visited a town or city after this, they had a program which they always followed. First they would place themselves in front of an idol temple or in an open square. Here they would sing a hymn which always attracted a crowd. Next, any one who wanted a tooth pulled was invited to come forward. Many accepted the invitation gladly and sometimes a long line of twenty or thirty would be waiting, each his turn. The Chinese had considerable nerve, the Canadian discovered, and stood the pain bravely. They literally "stood" it, too, for there was no dentist's chair and every man stood up for his operation, very much pleased and very grateful when it was over. Then there were quinine and other simple remedies for malaria handed round, for in a Formosan crowd there were often many shaking in the grip of this terrible disease. And now, having opened the people's hearts by his kindness, Kai Bok-su brought forth his cure for souls. He would mount the steps of the temple or stand on a box or stone, and tell the wonderful old story of the man Jesus who was also God, and who said to all sick and weary and troubled ones, "Come unto me,... and I will give you rest." And often, when he had finished, the disease of sin in many a heart was cured by the remedy of the gospel.
