We left Suddiya on the 7th of February 1837, and reached Kedding on the 10th; stayed there one day, and reached Kamroop Putar, where I found Major White and Lieut.  Bigge on the 12th.  The jungle to this place was similar to the usual jungle of the Singpho country, very generally low, and intersected by ravines.  We crossed en route the Karam river, the Noa Dihing, or Dihing branch of the Booree Dihing, on which the Beesa’s old village was situated; and lastly the Kamroop.  Kamroop Putar is close to the Naga hills; it is a cultivated rice tract, on the river Kamroop.  This river is fordable, with frequent rapids.  The only curious things about it are the petroleum wells, which are confined to three situations.  The wells are most numerous towards the summits of the range; and the place where they occur is free from shrubs.  The petroleum is of all colours, from green to bluish white; this last is the strongest, partaking of the character of Naphtha, it looks like bluish or greyish clay and water.  The vegetation of the open places in which the wells are found, consists of grass, Stellaria, Hypericum, Polygonum, Cyperaceae, Mazus rugosus, Plantago media, etc., all of which are found on the plains.  One of the wells is found on the Putar, or cultivated ground; the petroleum in this is grey.  The Kamroop river above this Putar, strikes off to the eastward, and the Kamteechick, a tributary, falls into it from the south; this last is a good deal the smaller; the banks of the Kamroop are in many places precipitous.  About two miles from the Putar, a fine seam of excellent coal has been exposed by a slip:  {60} the beds are at an inclination of 45 degrees, and their direction is, I think, nearly the same with that of the left bank of the river in which they occur; immediately over the seam there is a small ravine, where three of the veins are still farther exposed.  Caricea, a new Dicranum, Alsophila ferruginea, Polytrichum aloides, Bartramea subulosa, and Jungermanniae are common near this spot.

Left Kamroop on the 19th, and proceeded in a S.W. direction for twelve miles, when we halted on the Darap Kha, at the foot of the Naga hills, opposite nearly to Beesala.  Nothing of interest occurred.

Feb. 21st.—­Commenced the ascent, and after marching about ten miles, halted in a valley near a stream.  Temperature 66 degrees.  Water boiled at 210.5 degrees, giving an altitude of about 77 degrees, or 383 feet above Suddiya.  The road was very winding, the path good, except towards the base of the hills:  the soil sandy, in places indurated, and resting on sandstone; but there is not yet sufficient elevation to ensure much change in vegetation.  Found Kaulfussia {61a} below in abundance, observed Castanea and a Quercus; three species of Begonia, and three or four species of Acanthacea.  In other respects the jungle resembles that of the Singpho territory.  Dicksonia is abundant.  Dipterocarpus of large size occurs.  Caught two innocuous snakes at the halting place. {61b}
