In July, 1917, Hosaka Kanai, a second-year student of the Morioka College of Agriculture and Forestry, a respected friend of Miyazawa Kenji, took part in the geological excursion to Chichibu, composed 296 Japanese poems during the excursion and wrote down them in the notebook entitled "Chichibu Shigensou " . The author extracted 154 poems in which technical terms such as rocks, minerals and geological phenomena are involved. The author classified these terms into several groups, academically explained and considered their outcropped points. Further, the author considered Kanai's emotion for Chichibu, Kanai's knowledges and tastes for rocks, minerals and geological phenomena, from their personifying. In view of these studies, the author brought into relief Kanai's characteristics as a natural scientist and interdisciplinary effects yielded by a natural scientist who has some knowledge of literature composes Japanese poems.

Quercus serrata subsp. mongolicoids is isolatedly distributed in the low altitude hilly terrain of Northern Kanto and Tokai region. In this study, we sampled their leaves, acorns, and cupules in Northern Kanto, and recorded the characteristics. Morphologically, Q. serrata subsp. mongolicoides is well divided from Q. serrata subsp. serrata, but similar to Q. crispula (distributed in higher mountain district in Japan) and Q. mongolica (distributed in Far East Russia, China, and Korean peninsula).
Then we compared the leaves of Q. serrata subsp. mongolicoides from those of Q. crispula and Q. mongolica. As a result, the leaves of Q. serrata subsp. mongolicodes were similar to those of Q. mongolica than those of Q. crispula, by the factor of width/length ratio, number of veins, and tooth acuteness. In acorns and cupules, Q. serrata subsp. mongolicoides has some differences from Q. crispula, and corresponded to the characteristics of Q. mongolica in the literature.
