IN 1905 the hope was expressed by the Survey of India that in twenty-five years maps of the whole Indian Empire on a scale of one inch to a mile would be available. The Annual Report for 1936 (Calcutta. 2s. 6d.) points out that this hope is far from realization, and that a little more than half the area is now mapped on that scale. When it was realized in 1913 that the scheme could not be completed for many years, it was decided to reduce the scale of survey for the less populous areas. As a result, two-thirds of the country is now covered by modern maps ranging in scale from one inch to a quarter inch. In the year under review more than fifty-three thousand square miles was surveyed, in addition to a certain amount of revision. The report contains full index sheets to all the scales, including the sheets of the Carte Internationale on a scale of one million which cover India and adjoining lands.
