XXXVII. Memoir on the Eastern Branch of the River Indus, giving an Account of the Alterations produced on it by an Earthquake, also a Theory of the formation of the Runn, and some Conjectures on the Route of Alexander the Great; drawn up in the years 1827–1828
In the north-western extremity of our Indian possessions, and under the tropic, is situated the small and sterile territory of Cutch, of importance to the government from its advanced position, but of more attraction to the student of history from its western shore being washed by the waters of the classic Indus and from its proximity to the scene of Alexander's glories. Divested, however, of these alluring enticements to enter on its history, Cutch is a country peculiarly situated. To the west it has the inconstant and ever varying Indus. To the north and east the tract called Runn, which is alternately a dry sandy desert and a muddy inland lake. To the south it has the Gulf of Cutch and the Indian Ocean, with waters receding yearly from its shores.
