Meridian, deduced from the observations of the Sun.......... 260° 47'-1.
No. 2. Tezpur, in Assam.
Coming from Bhutan, this was the first station I reached. It is situated on the
right side of the Brahmaputra, and has during the last few years become a very
important place for the manufacture of lac, and for the cultivation of tea and indigo.
Tea ought to be particularly mentioned in connection with Tezpur, on account
of Mr. Bruce, a resident of this station, having first found it growing wild in Assam.
My instruments were placed near the circuit bangalo, a government building
erected on a slight eminence for the temporary residence of officers while travelling.
