Information obtained from Official gazettes

As written in the preface to Sadajiro's 朝鮮鉱床論, there was a time when he taught in the mining department of the private 大同工業専門学校 (Daidō industrial college(?)). When and where did the school exist? Searching the official gazette for information on the school, we will find a description of its establishment approval. In addition to the address and admission quota, we can see that at first there was only the Department of Mining (see the image below).

 

In addition to information on educational institutions such as this, the official gazette also includes other Ordinances and Public Notices from the 統監府 (Meiji 38 (1905) - Meiji 43 (1910)) and the 朝鮮総督府 (Meiji 43 (1910) - Showa 20 (1945)) are announced, and we can get information on the years and contents of various events.
