The revision of this book has been the slow though constant occupation of several years. When at last I had completed the revised copy and made arrangements as to its publication, in March, 1882, my health failed, and under a partial paralysis I was rendered incapable of further labor. My son, Frederick Wells Williams, who had already looked over the copy, now assumed entire charge of the publication. I had the more confidence that he would perform the duties of editor, for he had already a general acquaintance with China and the books which are the best authority. The work has been well done, the last three chapters particularly having been improved under his careful revision and especial study of the recent political history of China. The Index is his work, and throughout the book I am indebted to his careful supervision, especially on the chapters treating of geography and literature. By the opening of this year I had so far recovered as to be able to superintend the printing and look over the proofs of the second volume. My experiences in the forty-three years of my life in China were coeval with the changes which gradually culminated in the opening of the country. Among the most important of these may be mentioned the cessation of the East India Company in 1834, the war with England in 1841-42, the removal of the monopoly of the hong merchants, the opening of five ports to trade, the untoward attack on the city of Canton which grew out of the lorcha Arrow, the operations in the vicinity of Peking, the establishment of foreign legations in that city, and finally, in 1873, the peaceful settlement of the _kotow_, which rendered possible the approach of foreign ministers to the Emperor’s presence. Those who trace the hand of God in history will gather from such rapid and great changes in this Empire the foreshadowing of the fulfilment of his purposes; for while these political events were in progress the Bible was circulating, and the preaching and educational labors of missionaries were silently and with little opposition accomplishing their leavening work among the people.
