 HEADOUAETERS OF SURVEY DEPARTMENT. 



The Headquarters Offices of the Department of the Surveyor- 

 General comprise six different offices, five in Calcutta, and one in 

 Dehra Dun, whence the operations are directed, and where the 

 results of the field surveys are worked up into final shape for general 

 administrative use. These offices consist of — 



(1.) The Surveyor- General's Office (including also the drawing, 

 engraving, and map issue branches). 



(2.) The Lithographic Office. 



(3.) The Photographic Office. 



(4.) The Mathematical Instrument Office. 



(5.) The Revenue Survey Office. 



(All at Calcutta.) 



(6.) The Trigonometrical Survey Office at Dehra Dun. 



In 1877 the Calcutta branches were still in different buildings 

 some distance apart one from another, and a good deal of incon-

 had long been felt and recognised by Government sanctioning designs 

 for new offices ; but it was not till 1882 that any part of the new 

 building was sufficiently advanced to be occupied. In that year 

 the new building designed to accommodate the Surveyor- General's 

 and Revenue Survey Offices was ready, and within a month after 

 the close of the year the houses in Park Street and Middleton Street, 

 in which the offices had previously been located, were vacated, and 

 the entire stock of maps and records — the collection of nearly a 

 century — of copper plates, and plant of all descriptions, was trans- 

 ferred to their new quarters. The new building proved to be well 

 designed and constructed. It is commodious and airy ; it gives 

 sufficient space for all the members of the office, and excellent 

 accommodation and lighting for the engravers and draftsmen, who 

 had long had to work in crowded and inadequately lighted rooms. 

 In 1882-83 it was decided to amalgamate the correspondence and 

 accounts offices of the Surveyor-General's Office and the Revenue
