Chapter III - In the third chapter the adminstrative system of the Kushana together with the Kushan idea of divine kingship have bean disouased. Chapter IV - The fourth chapter deals with Kushan commercial relations with China, Home and the Indian peninsula. The overland and the maritime trade and the craft and trade guild organisations have been studied in detail.

Lists of the deities, found on the Kushan coin, are given, Attempts are, also, made to study the social conditions concerning caste, the position of women, costume, musical Instruments, education and learning.
