78 " Address, [Feb. 



comprising an area of about 77 square miles, of which 21 were surveyed 

 on the scale of 6 inches, and 56 on the scale of 2 inches to the mile. Use- 

 ful maps of the whole tract have been made. 



The Survey of the Town of Mandalay on the scale of 40 feet to 

 an inch has been completed. 



The triangulation from Mandalay to Bhamo has been completed 

 and extended thence to Senbo. 



In the Southern Shan States, Captain Jackson has carried on a 

 survey from Fort Stedman, down the valley of the Balu Chaung, to 

 Pekon, making a detour through the Southern States of the Myelat. 

 From Pekon he advanced to Loipok and eastwards, across the Pon and 

 Tein rivers, to Maukme, Mainghan and the Salwin River ; thence 

 proceeding northwards, via Mone, Legya and Maing-Kiang to Maingye 

 and Manse, and on, through Lashio, Mansam and Panglon, to Thibaw. 



In the Northern Shan States, about 3,500 square miles was surveyed 

 from Thibaw to Nansan and across the Myit-nge or Narntu River to 

 Theinni, on the Salwin, and thence, via Maingyaw, to Manse. 



Materials thus exist for a reliable map of the Shan States. 



The whole of the Taw country has been thoroughly surveyed, and 

 on the north a connection has been made with the work executed by 

 Col. Woodthorpe's party last year in the Kubo Valley. 



A considerable extent of country was surveyed by the surveyors 

 accompanying the column which proceeded from Bhamo to Mogaung 

 and thence to the Jade-Mines and Endawgyi Lake, returning, via Sakan 

 and Mogaung, to Katha on the Irrawaddy. Surveys were made in the 

 Katha District and the survey of the Irrawaddy downwards from Bhamo 

 to Tigyaing completed. The Chindwin and Irrawaddy Rivers were also 

 surveyed in the neighbourhood of their junction. 



Further important results may be expected from the expeditions 

 proceeding this season from Mogaung to the Kachin Hills and the head- 

 waters of the Uru and Chindwin Rivers, and from the expedition to the 

 Chin country, which will start from Kolewa. A third starts from Mogok, 

 in the Ruby-Mines district, proceeding via Momeit to Taungbain and 

 back ; while another, starting from Bhamo will go south-east to the 

 Shweli River and over Northern Theinni. 



Trigonometrical B ranch. —Triangulation has been extended down 

 the Madras coast for 370 miles, thus completing the scheme for this 

 part of the coast. The object of it was to fix the positions of beacons, 

 temples, lighthouses and other conspicuous objects for the use of the 

 Marine Survey of India and it now extends from False Point to Point 

 Calimere in the Tanjore District. The party has been transferred to 

 Burmah to carry on the triangulation there. A new 12-inch microscope
