This is plate 7 from James Baillie Fraser's 'Views of Calcutta and its Environs'. Fraser (1783-1856) arrived in Calcutta in 1814 and in six years produced thse animated sketches of the busy city, published later as a collection of twenty-four superbly aquatinted plates.The Salkia Ghat is the bank opposite Chandpal Ghat, the main landing place for tourists. Fraser made a feature of the river in many of his views of Calcutta, and this dramatic print shows a storm approaching from the north-west.
