In February, 1864, Dr. and Mrs. House left on a visit to the United States, the state of Mrs. House’s health requiring it; and a few months later Mrs. Mattoon, whose asthmatic trouble had returned, was compelled to take her final leave of Siam. Her husband remained to finish the important work on which he had long been engaged of making a revised translation of the New Testament into Siamese. Mr. Wilson, whose health had become impaired, accompanied Mrs. Mattoon and her children to America. In December, 1864, the Rev. Dr. Dean, whose shattered constitution had been restored by eleven years’ sojourn in his native land, gladly returned (with Mrs. Dean, Miss F. Dean and the Rev. C. H. Chilcott) to take charge again of the Baptist Board’s mission-work for the Chinese and of the Chinese church in Bangkok, which he had founded. Mr. Chilcott was removed by death before he had entered on the second year of his missionary life. In December, 1865, the Rev. S. Mattoon took his final and regretful leave of the land and the people for whose good he had labored so long and so faithfully――a loss to the community as well as to the mission. From the date of his embarkation for the field to that of his arrival in the United States on his return was just twenty years. April 4, 1866, the Rev. P. L. Carden and wife arrived to join the Presbyterian mission, and in July the Rev. J. Wilson returned with Mrs. Kate M. Wilson. In July also came Miss A. M. Fielde, to be connected with the Chinese department of the Baptist mission. Dr. and Mrs. House returned in December from their visit home, with health renewed. The industrial school for girls in Petchaburee, which has since brought so many of the women and girls of that city under daily Christian instruction and training in habits of neatness and industry, commenced by Mrs. McFarland the year previous, was now an established success. The boys’ boarding-school at Bangkok prospered under Mr. George’s superintendence. The fall of 1866 was a season of marked religious interest at the Bangkok station; there were several decided cases of conversion, and a daily prayer-meeting instituted by the converts was well sustained. In 1867 (October 1) the missionaries write: “During the past twelve months more additions have been made to the native church than in all the previous years of its history.” Eleven had been received at Bangkok and four at Petchaburee――nine of the number pupils of the mission-schools.
