170 GEOGRAPHICAL SURVEYS AND EXPLORATIONS. 



miles mapped on the quarter-inch scale, the greater portion of which 

 lay in the Shan States and Bhamo district. In 1889-90 one party 

 was at work in lieu of two, and the out-turn was a little smaller. 

 But the total area mapped during the last four years in Upper 

 Burma amounts to 70,852 square miles, a result most creditable to 

 Major Hobday, Captain Jackson, Mr. Ogle, and the other members 

 of the party. To Mr. Ogle the Gill Memorial Medal for 1889 was 

 awarded by the Council of the Royal Geographical Society in 

 recognition of his excellent survey work in the North-eastern frontier 

 and in Burma. 



A small survey party under Lieutenant "W. H. Pollen, R.E., an 

 energetic and popular young officer, accompanied the military 

 expedition to the Lushai Hills in 1888-S9 ; but owing to the 

 unfortunate illness and subsequent death of Lieutenant Pollen, but 

 little wox'k was clone, though tlie information acquired by Mr. James, 

 who succeeded to the charge of the party, proved very useful in the 

 following year. The expedition in that year (18S9-90) consisted of 

 two columns, one starting from Kan, in the Myittha Valley, and 

 proceeding into the Chin Hills, and the other from Chittagong being 

 directed into the Lushai Hills. Each column was accompanied by 

 a small survey party under Lieutenants Renny-Tailyour, and Bythell, 

 R.E., respectively. The operations in the Chin Hills resulted in the 

 survey of about 3.000 square miles, and those in the Lushai Hills of 

 about 0,000 square miles of new country. The triangulation of both 

 parties wore successfully connected near Ilaka. 



A survey party, under Captain Jackson, R.E., which accompanied 

 the Anglo-Siamese Boundary Commission, mapped over 9,000 

 square miles on the {-inch scale. Mr. Ogle, who was a member of 

 the survev party, was detached at the outset to work independently, 

 with instructions to survey the four States of Mdng Ton, Mong 

 Hang. Mono- Chut, and Mong Tar. This he successfully completed. 



In conclusion, mention should be made of an interesting piece 

 of work, which though carried out some years previously, helped 

 to throw a good deal of light on the conterminous region of 

 Upper Burma and Assam. In the early part of 1879 Captain 

 J. E. Sandeman, in charge of the cadastral survey in the 

 Hanthawadi district of British Burma, was requested to train 

 a native for exploring the upper course of the Irawadi river 

 beyond Bhamo. Towards the end of the year the man had acquired 

 a sufficient knowledge of his duties to be started on a preliminary
