The journals of Major James Rennell, first surveyor-general of India: Written for the information of the governors of Bengal during his surveys of the Ganges and Braghmaputra rivers 1764 to 1767

The Journals of Major James Rennell, edited by T.H.D. Touch, document Rennell's pioneering surveys of the Ganges and Brahmaputra rivers during his tenure as the first Surveyor-General of India. Compiled for the Governors of Bengal, these journals provide valuable insights into 18th-century cartography, geography, and colonial administration. Rennell’s detailed observations contributed significantly to British understanding of Indian terrain and navigation routes, laying the groundwork for future mapping efforts in the subcontinent. His work remains a cornerstone of early geographical exploration in India.
