At school, however, some of the books, being treated courteously, were kept and stored safe in a box made of paulownia wood, because "The book was granted by the Emperor and we fear soiling it in a classroom" thus allowing only a few important figures such as a principal to see: it is, without question, not the aim of the distribution, though.
しかし、実際の教育現場では「天皇陛下から賜ったものを授業で汚すなど畏れ多い」という理由で少数部が桐箱に納められて厳重に保管されて校長などわずかな人物しか見ることが許されないという極めて厳重な取り扱い方を受けた（もちろん、そのような趣旨で頒布された訳ではない）。
