Divided in two volumes, the work has four sections documenting the history and chronicles from 8th century Gujarat (now in India) to arrival of British and folk literature of Gujarat as well as an historical account of the place and people he came to know during his stay in Gujarat. It was later translated into Gujarati in 1869.
The first book gives an account of the rise and fall of the Chavada and Vaghela dynasties. It covers the period from about the eighth to thirteenth century.
