This year (1838) was one memorable in the history of the Presbyterian mission, as in it occurred the visit of the Rev. R. W. Dee, who had been directed by the Presbyterian Board to proceed to Bangkok and report upon its eligibility as a station for the missionary operations they were about entering upon for the Chinese, so difficult of access in their own country. During his month’s stay in Siam, Mr. Dee found so large a field unoccupied, where laborers from our branch of the Church would be gladly welcomed, that he urged upon the Board the establishment of a mission in that land, not only to the Chinese there, but to the Siamese also. November 5, 1838, Dr. Bradley was ordained a minister of the gospel by his congregational associates. In 1839 the Siamese government availed itself of one of the mission printing-presses to multiply copies of a royal proclamation against opium, and had an edition of nine thousand copies struck off. In August of this year the Rev. Mr. and Mrs. Slaftee of the Baptist mission arrived. In 1840 vaccination was successfully introduced into Siam by Dr. Bradley,――a great boon to the people, among whom small-pox often committed fearful ravages. The American Board’s mission was strongly reinforced in its Siamese departments early in the year by the arrival of the Rev. Messrs. Jesse Caswell, Asa Hemenway, N. S. Benham and their wives, with Miss Pierce――Mr. Benham to lose his life in one short month by drowning, his boat capsizing in the Menam when returning from an evening prayer-meeting. The Rev. Messrs. French and Peet, with their wives, also arrived in May. To the Chinese department of the Baptist mission came the Rev. Josiah Goddard and his wife in October. It was in August of this same year that the Rev. William Buell and wife, the first missionaries of the Presbyterian Board to the Siamese, arrived in Bangkok. There were then in Siam no less than twenty-four adult male and female missionaries. But the next year Mr. Slaftee died of dysentery and Mrs. Johnson of brain fever, and the widowed Mrs. Benham returned to the United States. In 1842, Mr. French died of consumption, and the following year his widow left Siam for the United States. In 1842, by the treaty made at the close of the war between England and China, the island of Hong Kong was ceded to the English and five important seaports thrown open to foreign residence and trade. Dr. Dean, under instruction from his Board, who hastened to enter the now unbarred gates of access to the Chinese empire, removed early in the year to Hong Kong, leaving the Chinese church in Bangkok in charge of Mr. Goddard.
