I think that this is written by T. Ruddiman Johnston to the Editor... he offered to them his works (photography, sketches) and he listed where his works already have been published.
Here is some kind of his shorten biography:
JOHNSTONE, T. R. [T. Ruddiman] [JOHNSTON] / P IV / GB / TR /
- In 1900 he came to Japan and settled as Sole Agent under his name in Tokyo. He had specialized in the import of all kinds of English Papers, Stationary, and Bookbinding Machinery. His agency was located until 1902 at # 18, Hiyoshi-cho, Shimbashi, Tokyo, and as of 1903 at # 12, Ginza, Nichome Kyobashi-ku, Tokyo. - From 1906 on he is no longer listed in Japan.
