And so he and his Formosan wife said good-by, amid tears and regrets on all sides, and leaving Mr. Junor in charge with A Hoa to help, they set sail for Canada. It was just a little over seven years since he had settled in that little hut by the river, despised and hated by every one about him; and now he left behind him twenty chapels, each with a native preacher over it, and hundreds of warm friends scattered over all north Formosa.

He was not quite the same Mackay who had stood on the deck of the America seven years before. His eyes were as bright and daring as ever and his alert figure as full of energy, but his face showed that his life had been a hard one. And no wonder, for he had endured every kind of hardship and privation in those seven years. He had been mobbed times without number. He had faced death often, and day and night since his first year on the island his footsteps had been dogged by the torturing malaria.

But he was still the great, brave Mackay and his home-coming was like the return of a hero from battle. He went through Canada preaching in the churches, and his words were like a call to arms. He swept over the country like one of his own Formosan winds, carrying all before him. Wherever he preached hearts were touched by his thrilling tales, and purses opened to help in his work. Queen's University made him a Doctor of Divinity; Mrs. Mackay, a lady of Detroit, gave him money enough to build a hospital; and his home county, Oxford, presented him with $6,215 with which to build a college.

He visited his old home and had many long talks of his childhood days with his loved ones. And he was reminded of the big stone in the pasture-field which he was so determined to break. And he thanked his heavenly Father for allowing him to break the great rock of heathenism in north Formosa.

He returned to his mission work more on fire than ever. If he had been received with acclaim in his native land, his Formosan friends' welcome was not less warm. Crowds of converts, all his students who were not too far inland, and among them, Mr. Junor, his face all smiles, were thronging the dock, many of them weeping for joy. It was as if a long-absent father had come back to his children.

The work went forward now by leaps and bounds. Mackay's first thought, after a hurried visit to the chapels and their congregations, was to see that the hospital and college were built.

All day long the sound of the builders could be heard up on the bluff near the missionaries' houses, and in a wonderfully short time there arose two beautiful, stately buildings. Mackay hospital they called one, not for Kai Bok-su—he did not like things named for him—but in memory of the husband of the kind lady who had furnished the money for it. The school for training young men in the ministry was called Oxford College, in honor of the county whose people had made it possible.

Oxford College stood just overlooking the Tamsui river, two hundred feet above its waters. The building was 116 feet long and 67 feet wide, and was built of small red bricks brought from across the Formosa Channel. A wide, airy hall ran down the middle of the building, and was used as a lecture-room. On either side were rooms capable of accommodating fifty students and apartments for two teachers and their families. There were, besides, two smaller lecture-rooms, a museum filled with treasures collected from all over Formosa by Dr. Mackay and his students, a library, a bathroom, and a kitchen.

The grounds about the college and hospital were very beautiful. Nature had given one of the finest situations to be found about Tamsui, and Kai Bok-su did the rest. The climate helped him, for it was no great task to have a luxurious garden in north Formosa. So, in a few years there were magnificent trees and hedges, and always glorious flower beds abloom all the time around the missionary premises.

But all this was not accomplished without great toil, and Kai Bok-su appeared never to rest in those building days. It seemed impossible that one man should work so hard, he was in Tamsui superintending the hospital building to-day, and away off miles in the country preaching to-morrow. He never seemed to get time to eat, and he certainly slept less than his allotted four hours.
