Originally published in 1898. INTRODUCTION: Since the time when I made my first journey into Cambodia to examine its ancient cities, it has been my constant endeavour to show how the explorer may add not only to the interest but to the permanent value of his work by the use of photography. To those of my readers interested in photography I may add a note on my method of working. All my negatives were taken by the wet collodion process, a process most exacting in its chemistry, especially in a land where the science is practically unknown. With over 100 illustrations this unusual works will appeal greatly to anyone interested in early China and photography. Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
