Within a month after the new station at Petchaburi was opened, the missionaries reported the extraordinary case of a Siamese who had come to believe upon God and Christ through portions of the Scripture that had come into his hands, although he had never seen a missionary and had never met a Christian. The name of this man was Nai Kawn. Writing to his family in America under date of July 17, 1861, Dr. House quotes in part from a letter which Mrs. McFarland had written to Mrs. House giving the story; and in part from Mr. McGilvary: “I wish Dr. H. could be here to examine a ‘diamond’ we have found here (_i. e._, a native of Petchaburi, which name means ‘city of diamonds’). We do believe it a true, genuine diamond, and though it needs to be polished it will one day shine in our Saviour’s diadem in glory. It seems an extraordinary case in many respects. The man is a middle aged Siamese, resides about five miles from Petchaburi capital; had never seen a missionary, but some of our Christian tracts and portions of the Scripture—which he had got from his neighbours—appears to have been the means of enlightening his mind and converting his heart. He had taught his little boy the Lord’s prayer and the ten commandments.” “Mr. McG. writes: He certainly has the clearest idea of the Scripture of any heathen convert I have met with. He literally knows John, Acts, Romans (all the Bible he has yet seen) by heart; can repeat whole chapters without missing a word. He evidently studied for months and years.... Seems delighted to find us, as if his highest wish had been realised. Wishes to come and live with us at once to learn more perfectly the Gospel, and to assist to teach and distribute books. To try his sincerity, no encouragement was offered him, fearing he might wish support from the missionary. ‘Oh, no,—he wished no compensation, as he had enough to live on.’ He has a few hundred ticals and wants no more. He has settled one son with three hundred ticals, and the other son he has just left with us where he can be taught the Christian religion. Says he would not give up the new religion for the offer of being king of Siam. Comes to worship, walking five miles over muddy roads. Longs to see another Siamese Christian—has hunted all over to find one.” In the fall of that year Dr. and Mrs. House were obliged to spend several months in Petchaburi to relieve the McFarlands, who went to Bangkok for medical attendance. During that sojourn the doctor had several conversations with Nai Kawn; and in letters to his brother in America narrates the confession of that remarkable convert:
