This is a report which presents an introduction to trade economy of the Arun valley. The article is a research report on anthropological explorations of the eastern Himalayas, where the author visited eastern Nepal hills, starting from Solu and proceeding to Dharan by way of Okhaldhunga, Bhojpur, Chainpur, and Hile. The author feels that a study will provide quantification of the trade of goods imported or exported. In addition the article seeks to draw attention to the powerful transport economy. It includes a one page map of eastern Nepal with pages of records of porters passing through hills going northward. (Rajeev Ranjan Singh 2007-01-12)
