The Japanese are doing much good work. They are gathering old books and records. Up to 1915 more than one hundred and fifty thousand books, manuscript and printed, had been gathered by the Government-General. Among these were the “Annals of Yi” numbering sixteen hundred and thirty-three volumes and the “Royal Diaries,” aggregating thirty-one hundred and ninety-nine volumes, “all hand-written with the brush.” Of the “Annals” there were four sets made under the Korean government for the four old royal libraries. The “Royal Diaries” were compiled at the king’s orders; they dated from Yi Tajo himself, but those up to near the end of the sixteenth century were burned by the Koreans at the time of the Hideyoshi invasion; those now existing cover the period from 1623 to 1907. Japanese scholars have organized a society for reprinting old and rare Korean books and have gotten out many volumes. They are piling up direct observations also. From 1909 to 1915, they conducted a peninsula-wide survey of ancient monuments and have printed the results in four fine volumes, with splendid illustrations, under the title _Chosen ko seki gafu_. They have taken steps toward the preservation and, where necessary, the reconstruction of important monuments and notable buildings. They are copying the monastery records and ultimately will have a complete set of all that remain. The originals ought to be left in possession of the monasteries themselves, with the obligation to guard and keep them safely. As to monumental inscriptions, the Government-General has been equally industrious. Up to March, 1915, there had been made thirteen hundred and seventy-seven direct rubbings from inscribed stones, of which forty-four represented Sylla, forty-three the period of the Koryu Dynasty and thirteen hundred and three the Yi Dynasty. It is fortunate that this preservation of material is being undertaken. The world will profit by it, though it may still be long locked up in Chinese characters. In this book the work of Yi Nung Hwa is mentioned. His Buddhist magazine should yield some data of value. If his History of Korean Buddhism is printed it ought to be of high importance, as he naturally has a much easier task in consulting the original sources than any foreigner. If his work is done with care and critical judgment it should be the necessary foundation for all future study. All depends upon how he performs his task. Readers who become interested in our lectures are advised to read Bishop Trollope’s admirable _Introduction_. It clears the ground and indicates the direction of further studies.
