1. _Situation and extent_.--The Deyra Doon, or Valley of Deyra, is situated in latitude 3 deg. 18 min. north, and in longitude 78 deg. east. It is about 60 miles in length from east to west, and 16 miles broad at its widest part. It is bounded on the south by the Sewalick range of hills, and on the north by the Himalayas proper, which are here nearly 8,000 feet above the level of the sea. On the west it is open to the river Jumna, and on the east to the Ganges, the distance between these rivers being about 60 miles. In the centre of this flat valley, the Kaolagir tea plantation has been formed. Eight acres were under cultivation in 1847. There are now 300 acres planted, and about 90 more taken in and ready for many thousands of young plants raised lately from seeds in the plantation. 2. _Soil and culture_.--The soil of this plantation is composed of clay, sand, and vegetable matter, rather stiff, and apt to get "baked" in dry weather, but free enough when it is moist or during the rains. It rests upon a gravelly subsoil, consisting of limestone, sandstone, clay-slate, and quartz rock, or of such rocks as enter into the composition of the surrounding mountain ranges. The surface is comparatively _flat_, although it falls in certain directions towards the ravines and rivers. The plants are arranged neatly in rows 6 feet apart, and each plant is about 4½ feet from its neighbour in the row. A long, rank-growing species of grass, indigenous to the Doon, is most difficult to keep from over-topping the tea-plants, and is the cause of much extra labor. Besides the labor common to all tea countries in China, such as weeding, and occasionally loosening the soil, there is here an extensive system of irrigation carried on. To facilitate this, the plants are planted in trenches, from four to six inches below the level of the ground, and the soil thus dug out is thrown between the rows to form the paths. Hence the whole of the plantation consists of numerous trenches of this depth, and five feet from centre to centre. At right angles with these trenches a small stream is fed from the canal, and, by opening or shutting their ends, irrigation can be carried on at the pleasure of the overseer. 3. _Appearance and health of plants_.--The plants generally did not appear to me to be in that fresh and vigorous condition which I had been accustomed to see in good Chinese plantations. This, in my opinion, is caused, 1st, by the plantation being formed on _flat land_; 2nd, by the system of _irrigation_; 3rd, by too early plucking; and 4th, by hot drying winds, which are not unfrequent in this valley from April to the beginning of June.
