3.3.8

Having made 'Inayat Beg, who for a long period in the reign of my father had been Master of Works (Diwan-i-buyutat) and held the rank of 700, half-vizier of my dominions in the place of Wazir Khan, I gave him the high title of I'timadu-d-daula with the rank of 1,500, and I appointed Wazir Khan to the Diwani of the province of Bengal, and assigned to him the settlement of the revenues thereof. To Patr Das, who in the time of my father had the title of Ray Rayan, I gave the title of Raja Bikramajit. The latter was one of the great Rajas of India, and it was in his reign that astronomical observatories were established in India. I made Patr Das Master of Ordnance, and ordered that he should always have light artillery in the arsenal, 50,000 light guns and 3,000 gun-carriages, ready and in efficient order. He was a khatri by caste, and rose in my father's service from being accountant of the elephants' stables to be diwan and an amir. He is not wanting in military qualities and in administrative skill. I made Khurram, the son of Khan A'zam ('Aziz Koka), who had had the rank of 2,000, an officer of 2,500.
