224 HEADQUARTERS OF SURVEY DEPARTMENT. 



Afghanistan ; but, on the other hand, there was a great increase 

 in the number of cadastral maps printed, the voluminous character 

 of which has always proved a very laborious undertaking. 



The despatch of the Indian troops to Egypt in 1881-82 neces- 

 sitated the drawing and publication of a map of Lower Egypt, as 

 well as maps of the Suez Canal, Cairo, and Alexandria.. All these 

 came into great demand on the outbreak of hostilities. Happily the 

 collection in the Survey Department contained some excellent 

 French maps of Egypt, and from these single specimens large 

 numbers of copies were rapidly obtained by photo-zincography, 

 issued to the troops, and also sold tc the public. 



In September of the same year (1881) the Venice Geographical 

 Congress and Exhibition took place. Colonel C. T. Haig, E.E.,was 

 delegated thither by the Government of India as their representative, 

 and Sir Henry Thuillier and Captain Baird were subsequently depuLed 

 in the same capacity from England by the Secretary of State. Sir 

 H. Thuillier and Colonel Haig were also appointed British Commis- 

 sioners by Lord Granville. Collections of maps, charts, &c, were 

 despatched by the Indian Government, Ordnance Survey, and 

 Admiralty, and the Indian delegates obligingly took charge of the 

 arrangement and organisation of the English maps, &c, in addition 

 to their own exhibits, which included a large and representative 

 selection of Indian maps, as well as the great theodolite and other 

 survey and tidal instruments. Two letters of distinction (the highest 

 award) were given to the Survey of India in Classes I. and VIII., as 

 well as two medals for native explorers (already mentioned at page 88, 

 note), a diploma of honour to the Jlarine Survey of India, a medal 

 to Captain Baird for his tidal work in Class II., a medal in Class I. 

 to Colonel Haig for his topographical maps of Gujrat, and a medal 

 in Class VI. to Br. Hunter for his Gazetteer of India.* 



A map, based on triangulation, of the Nizam's dominions was 

 commenced in the following year, the old topographical sheets being 

 re-drawn in the regular standard forms on the one and half inch 

 scales and in a style ht for reproduction by photo-zincography. The 

 materials were very old, being derived from surveys in the 

 early part of the century. Unfortunately though old they are the 

 only materials available, no modem survey having been as yet made 

 of this enormous expanse of country iu Southern India, though 

 detached portions here and there have fallen into the field of 

 adjoining parties. During the same year (1882—83) an irrigation
