GROUP I.
ASSAM AND KHASSIA HILLS.

STATIONS 1 to 5.
Dibrugarh.—Tezpur.—Udelguri. — Gohatti. — Cherra Punji.

No. 1. Dibrugarh, in Upper Assam.

This is a permanent military station on the Brahmaputra, farthest removed from
its mouth. Sadia, though still higher up the river, is only temporarily occupied by
an officer and his escort.

The observations were made on the left side of the Brahmaputra, near an open shed
erected for the free use of Bhutias and of neighbouring hill tribes, when coming for
trading purposes to the station. Such sheds are called "namgarh", and are to be
seen in many of the villages of Assam.
