In the winter term 1835 he entered Dartmouth College at Hanover, New Hampshire, but remained only till the close of that academic year. It was here that occurred the deeper spiritual experience which he recalls in the words that open this chapter; a conscious conversion during a revival which swept through the college that winter. It was following this experience that in the same year he united with the Waterford church upon profession of faith. Why he did not continue at Dartmouth does not appear; probably the difficulty of access would have been a chief factor. However, in the fall of that year he entered Union College, at Schenectady, a few miles from his home. His work at Rensselaer and Dartmouth qualified him to enter the junior class, so that he graduated in the year 1837. He received the degree A.B. in course and the honour of Φ.Β.Κ.; and following three years of post-graduate work in teaching, he received the degree M.A. from his alma mater. The three years immediately following graduation from Union were spent in teaching; one year in Virginia, a year as principal of Weston (Conn.) Academy and a year as principal of the private school “Erasmus Hall,” in Brooklyn. He now entered upon his medical course, spending the year 1841-2 in the University of Pennsylvania, and the next year in the Albany Medical College. With the lapse of a year not accounted for in the record,—probably teaching in Virginia, to which he refers in telling of some chemical experiments—he graduated from the College of Physicians and Surgeons of New York with the degree M.D. in 1845. Upon completion of his medical course he offered himself to the Presbyterian Board of Foreign Missions (Old School), and was commissioned in 1846. He was assigned to Siam together with his college-mate, Rev. Stephen Mattoon, of Sandy Hill, New York, (now Hudson Falls). Placing himself under the care of the Presbytery of Troy he was licensed to preach. III THE LITTLE CHISEL ATTACKS THE BIG MOUNTAIN Siam was the first nation of the Far East to make a treaty voluntarily with Europe. Siam was the first Asiatic power with which the United States entered into diplomatic relations. Siam was the first Oriental people to adopt Western customs, upon accession of King Chulalongkorn, in 1868. Siam was the first non-Christian land to grant religious liberty to its subjects in relation to Christian missions, in 1870. Siam was the first field entered by the Presbyterian Board of Foreign Missions after its organisation. In Siam was organised the first Protestant church of Chinese Christians. In Siam the first zenana mission work was undertaken. Siam is the last independent state in which Buddhism is the established religion.
