Oxford College had been closed while Dr. Mackay was away, and the girls' school had not been opened since the war commenced, for it was not safe for the girls and women to leave their homes during such disturbed times. But now both schools reopened, and again Kai Bok-su with his cane and his book and his crowd of students could be seen going up to the lecture halls, or away out on the Formosan roads.
He had conquered so often, overcome such tremendous obstacles, and faced unflinchingly so many awful dangers for the sake of his converts, that it was no wonder that they adored him, their feeling amounting almost to worship. "Kai Bok-su says it must be so" was sufficient to compel any one in the north Formosa Church to do what was required. Surely never before was a man so wonderfully rewarded in this life. He had given up all he possessed for the glory of his Master and he had his full compensation.
A few happy years sped round. The time for him to go back home again was drawing near when there came the first hint that he might soon be called on a longer furlough than he would have in Canada.
At first, when the dread suspicion began to be whispered in the halls of Oxford College and in the chapel gatherings throughout the country, people refused to believe it. Kai Bok-su ill? No, no, it was only the malaria, and he always arose from that and went about again. It could not be serious.
But in spite of the fact that loving hearts refused to accept it, there was no use denying the sad fact. There was something wrong with Kai Bok-su. For months his voice had been growing weaker, the doctors had examined his throat, and attended him, but it was all of no use. At last he could not speak at all, but wrote his words on a slate.
And everywhere in north Formosa, converts and students and preachers watched and waited and prayed most fervently that he might soon recover. Those who lived in Tamsui whispered to each other in tones of dread, as they watched him come and go with slower steps than they had been accustomed to see.
"He will be well next month," they would say hopefully, or, "He will look like himself when the rains dry." But little by little the conviction grew that the beloved missionary was seriously ill, and a great gloom settled all over north Formosa. There was a little gleam of joy when the doctor in Tamsui advised him finally to go to Hongkong and see a specialist He went, leaving many loving hearts waiting anxiously between hope and fear to hear what the doctors would say. And prayers went up night and day from those who loved him. From the heart-broken wife in the lonely house on the bluff to the farthest-off convert on the Ki-lai plain, every Christian on the island, even those in the south Formosa mission, prayed that the useful life might be spared.
But God had other and greater plans for Kai Bok-su. He came back from Hongkong, and the first look at his pale face told the dreaded truth. The shadow of death lay on it.
Those were heart-breaking days in north Formosa. From all sides came such messages of devotion that it seemed as if the passionate love of his followers must hold him back. But a stronger love was calling him on. And one bright June day, in 1901, when the green mountainsides, the blue rivers, and the waving rice-fields of Formosa lay smiling in the sun, Kai Bok-su heard once more that call that had brought him so far from home. Once more he obeyed, and he opened his eyes on a new glory greater than any of which he had ever dreamed. The task had been a hard one. The "big stone" had been stubborn, but it had been broken, and not long after the noontide of his life the tired worker was called home.
They laid his poor, worn body up on the hill above the river, beside the bodies of the Christians he had loved so well. And the soft Formosan grass grew over his grave, the winds roared about it, and the river and the sea sang his requiem.
