Prajakich Korachakr (Jëm Bunnak). The author was at pains to collect and collate all the material available, and as he did so with perspicacity and a profound knowledge of antiquity, his book is a very good one. It is in fact one of the best works in the field of Siamese history, and it is much to be regretted that Phya Prajakich Korachakr died so young, as he gave promise of great things as a historian.
10.The Rajadhiraj. This is the history of Pegu, which His Majesty Phra Buddha Yotfa Chulalok ordered to be translated into Siamese in B.E. 2328. The first part has much to do with our history at the time when Sukhothai was the capital.

Many of them also helped in examining and comparing the many documents that were gradually placed in the Library. When any doubt arose the late King was approached, and His Majesty often gave his opinion on questions brought before him. Only two months before his lamented death the following letter was received from His Majesty:—
