often afterwards. Mr. Lane reports that it frequently proved of as- 
sistance, as a turning point to the arguments employed to persuade 
these loyal people to act as porters, to tell them they were required 
“on Her Majesty’s Service,” interpreted “ Maharanee ka kam.”. The 
operations were further impeded by clouds and mists, and latterly by 
storms of such severity that on one occasion the whole of the Bunder 
Bazar, on the bank of the Soorma, was utterly destroyed and no ves- 
tige left. Final observations were taken for 19 principal triangles 
arranged in a double series, extending over a direct distance of 62 
miles, and covering an area of 1,207 square miles. Hight important 
Snowy Peaks of the Bhotan Himalayas were fixed. 
16. During 1861-62, Mr. Lane was absent on leave on medical 
certificate, when his place was ably filled by Mr. W. C. Rossenrode, 
who extended the triangulation a direct distance of 89 miles -east- 
ward through Cachar towards Munipoor, and 25 miles southward 
towards Independent Tipperah, in all 114 miles, by 30 triangles ar- 
ranged in a double series covering an area of 2,024 square miles. 
Some of the stations were situated in the Jynteeapore district, but 
the observations at them were fortunately completed before the present 
rebellion broke out. Reciprocal observations had still to be taken to 
them from other stations around, necessitating the employment of 
Hindustani clashis to work the signals on them; the men though 
robbed and threatened, maintained their posts during the rebellion, 
and only came away when signalled to do so at the termination of 
the observations. 
17. Ihave already reported that on learning that the Bengal 
Government had ordered a survey of Independent Tipperah to be 
made, I arranged with Mr. Buckland, the Commissioner of Chitta- 
gong, for our triangulation to be carried across Tipperah, on the di- 
rect line from Cherra Poonjee to Chittagong, instead of taking an 
extensive circuit westwards, as was originally contemplated, in order 
to keep within British Territory, and away from a frontier believed 
to be insecure. Mr. Hllison was deputed to enter Tipperah to re- 
connoitre the country, and select sites for the stations. He was 
considerably delayed by having to wait for the Rajah’s Agents, but 
he made some progress, and is reported by Mr. Buckland to have 
“ behaved with much tact and patience, although he had to encoun- 
ter the usual obstructiveness of the Rajah and his people.” Mr. Elli. *
