A scarce 1850 blueback nautical chart of the Hooghly River, West Bengal, India by John Walker. The chart covers the mouth of The Hooghly and the Bay of Bengal as far a south as False Point. An inset in the upper left quadrant continues to follow the course of the Hooghly as far north as Calcutta (Kolkata). The chart offers countless depth sounds, sailing instructions, and notes on offshore dangers, shoals, and other practical information for the mariner. The Hooghly us a navigable distributary of the Ganges River. The river was an important trade artery in the colonial period and was partially responsible for the British establishing themselves at Calcutta. This chart is extremely scarce and we have identified no other examples offered in recent history.
John Walker (1787 - April 19, 1873) was a British hydrographer and geographer active in London during the 19th century. Walker published both nautical charts and geographical maps. His nautical work is particular distinguished as he was an official hydrographer for the British East India Company, a position, incidentally, also held by his father of the same name. Walker's maps mostly published after 1827, was primarily produced in partnership with his brother Charles Walker under the imprint J. and C. Walker. Among their joint projects are more than 200 maps for the influential Society for the Diffusion of Useful Knowledge Atlas (SDUK). In addition they published numerous charts for the British Admiralty, including Belcher's important map of Hong Kong and Carless' exploratory map of Karachi. The firm continued to publish after both Walkers died in the 1870s.
