Although the present Punjab is land locked and its commerce is carried through rail and road transport, the united Punjab under the colonial rule in the last five decades of nineteenth century had some commerce through river navigation. This commerce through Marine ships and boats was mainly confined to river Indus. This book gives an account of nature, volume and extent Marine Trade. It is based on the records of Marine Department of Punjab state and archival sources. It gives us a glimpse into marine technology, the somewhat irresponsible behaviour of Navy personnel and freight charges. It ends with the possibilities of reviving river trade in the nearest future. The statistics given in Appendices reflect the mode of financial tariffs and transactions.[edit]
