As I was one of the founders of this Nippon Institute of Mining and Metallurgical Engineers (Nippon Kogyo Kai), Dr. Hirota, President of the Institute, asked me to write a short sketch relating to the procedure and progress of the Institute during the past 50 years (1885-1935); that is, from its very begining up to this day. In January 18, 1885, our friends consisting mining engineers, metallurgists and geologists assembled together in a room of Geological Society, Nishi-Konyacho in Ginza, Tokyo.
These engineers and geologists discussed earnestly how to carry out to organize an Institute to promote the mining and metallurgical engineerings, and geological investigations in Nippon. We came to the conclusion to establish a very complete institution under the name of Nippon Kogyo Kai (Nippon Institute of Mining and Metallurgical Engineers). The final meeting we held was on the day of January 28th, 1885. That day has been considered as The Day of the Establishment of our Institute. And those who gathered on that day were 20 in number, but sorry to say that 18 men among them had already gone, remaining only two of them. These two survivors are Mr. Shigeru Sugata and myself, who are still quite healthy and vigorous as ever.
In this sketch, some outlines of important events happened in the 50 years, was described and brief notes on the personality of late Takato Oshima and Wataru. Watanabe, with whom I worked in Sado Mines, myself as chief mining engineer under them, or some time under one of them, for 11 years from 1884 to 1895. Both of these enlightened great men did splendid achievements in modernizing our mining and metallurgical engineerings of Nippon, in the Great Meiji Era. They and their deeds are all imperishable forever in our mining history.
Short descriptions of our distinguished honorary members, Yajiro Ito, Tsunashiro Wada and Marquis Kaworu Inouye, were somewhat precisely described. Yajiro Ito was one who sdid much for our Institute in promoting it to its perfect condition from very beginning soon after its organisation.
I have written somewhat in detail what we have done in welcoming the party of the members of the American Institute of Mining and Metallurgical Engineers who came to Nippon in the year of 1911. The party consisted of 82 ladies and gentlemen, among whom there were many prominent and distinguished mining authorities, including most honorable and esteemed authority in the mining circle, Dr. R. W. Raymond, who was so well known not only in America but all over the world. We paid a special attention to Mrs. Raymond and Dr. Raymond while they were in Nippon.
In the last part of this sketch, some future view of the Institute has been mentioned as my expectation for the prosperity of the Institute in the day coming as next 50 years.
