III. THE GEOLOGICAL SUKVEY OF INDIA. 



(With a Sketch-map.) 



By H. Woodward, F.G.S. 



Sixteen years have now elapsed since the Geological Survey of 

 India commenced its systematic labours, and it may now be inte- 

 resting to give some account of the progress that has been made, 

 and to note a few of the results to which the Government officers 

 have been led. 



Some time beforehand, in 1851, Mr. (now Dr.) T. Oldham, the 

 Superintendent of the Survey, arrived in Calcutta. 



The work which he was then required to do was to go from 

 place to place, and, without loss of time, to search for coal and 

 other minerals of economic value ; to furnish reports, and thus to 

 indicate by observations in a few places the important results that 

 might be obtained from a detailed survey of the whole of the 

 country. Great were the difficulties with which he had to contend 

 at the outset, and for a long time afterwards; so that not until 

 1856 was he able to establish that regular system of operations 

 carried on by a staff of officers, small at first, and even in 1863 

 numbering but fifteen geologists. 



No one was better fitted for the task in hand than Dr. Oldham ; 

 he had been Local Director of the Geological Survey of Ireland, 

 and was previously Professor of Geology in Trinity College, 

 Dublin.
