The political economy of inland navigation, irrigation, and drainage : with thoughts on the multiplication of commercial resources : and on means of bettering the condition of mankind, by the construction of canals, by the improvement of their various capacities for commerce, transfer, agriculture, household supplies, and mechanical power : and by the unlimited extension thereof into the remotest interior of Great Britain and of foreign parts / - Tatham, William (Printed for R. Faulder, 1799)
