At the suggestion of his Premier, Rishi, the first Emperor of Shin ordered all the books existing in his country to be collected and burned and the scholars who did not obey his will to be killed by being buried alive. By following the policy of increasing the number of unlearned people, he forced his feudalistic despotism easily in his country. In the court of Shin, of course, there were scholars and in its library there were kept a great many books. However, the scholars under the domination of the first Emperor of Shin were not able to seek the freedom of learning, nor were they able to criticize his policy at all. When Kou defeated Shin and burnt Kanyo, the capital of Shin, the books in the library of Shin Court were wholly destroyed. Then the period of Kan came, when people were able to study freely. Therefore, people came to need books, but, as in the days of Shin, almost all the books in the world had been destroyed, therefore, the scholars of Kan had to work hard to recompile the old books. In those days, related with the recompilation of the books, the rumors circulated that Fukusei, the old scholar, had taken out the books which had been hidden, pasted in the wall in the period of Shin, or that the books hidden in the wall of Koshi\u27s old house had been discovered. In this thesis I considered from many points of view whether it could be true or not that under the domination of the first Emperor of Shin scholars had hidden the books in the wall, or rather I suggested that as their excuse to prove the recompiled books to be the old traditional ones, the scholars said that the books had been hidden in the wall. I came to the conclusion that in the period of Shin they were unable to hide the books in the wall, and explained the reasoning by which I reached this conclusion
