A 1906 article by W. H. Moreland, Director of Land Records and Agriculture, on why cotton acreage in the United Provinces of India changes over time and between areas. It uses official statistics from 1860 to 1904 to show cotton growing concentrating in the Meerut, Agra and Allahabad divisions, helped by railways and canal irrigation. It also argues that the yearly area follows the ratio of cotton prices to wheat prices, as well as sowing-season rains and the lingering effect of earlier booms and slumps. Two tables give the regional distribution of cotton area and annual area with price ratios for 1861-1904.
