Funnel made of bamboo to allow the heated air from the choolahs to pass through the tea; it is seldom used; the Chinese tea manufacturers preferring one made in the tea basket by the hand.
Oven for firing green tea made of kucha bricks. The pans are inclined at an angle of 50. In front the oven is 3 feet 2 inches in height, behind 4 feet 8 inches, length 5½ feet, breadth 3 feet. Door 10 inches from the base, 1 foot 2 inches high, and 7 inches wide.
Frames for placing baskets. The first being inclined.
Baskets for collecting leaves.
Shovel, &c., used in regulating the fire.
Winnowing machine. This is a common winnowing machine, with a box 2 feet 10 inches in length, 1 foot 2 inches in breadth, and 1 foot 3 inches in depth, attached to the bottom of the hopper, and closely fitted into the middle of the circular apartment which contains the fanners. This box is entirely closed above (unless at the small opening receiving the hopper) and at the sides. At the base there are two inclined boards which project from the side of the machine 6 inches, and are partly separated from each other by angular pieces of wood. The end towards the fanners is open, the other is partly closed by a semicircular box which is moveable.
I shall now give the dimensions of the different parts of this machine, which may be useful to parties wishing to make up similar ones to those employed in the manufactories.
External frame 7 feet 2 inches in length, 18 inches in breadth, and 5 feet 8 inches in height. Hopper 2 feet 10 inches above, and 1 foot 8 inches in depth. Frame of box for fanners 3 feet 9 inches in diameter. Hopper frame 2 feet 7 inches. Semicircular box, in length 2 feet 5 inches and 7 inches in depth. Inclined plane at base, first 15 inches, second 13 inches.
I may briefly state how this machine acts. With the right hand the fanners are propelled by the crank, and with the left hand the bottom of the hopper is opened by removing the wood. The flat piece of wood (the regulator) is held in the hand to regulate the quantity of tea that passes down. An assistant then throws a quantity of tea into the hopper which escapes through the apartment, and there meets the air. The first kind of tea falls down the inclined plane into one box which has been placed to receive them, the second are propelled further on, and fall into another box, and the lighter particles are propelled on to the semicircular end, and fall into a third box.
Note on the culture of the tea plant at Darjeeling, in 1847, by Dr. A. Campbell, Superintendant.—About six years ago I received a few tea seeds from Dr. Wallich; they were of China stock, grown in Kumaon. I planted them in my garden in November, 1841, and had about a dozen seedlings in the month of May following, which were allowed to grow where they had come up, and rather close together. The plants were healthy from the commencement, and up to May, 1844, had grown very well; at this period the ground passed into other hands (Mr. Samuel Smith's), and I lost sight of them until last August, when Mr. Macfarlane, from Assam, who was acquainted with the tea plant in that province, arrived here. Being desirous of ascertaining how far the climate and soil of Darjeeling were suitable to the tea, I took him to examine the plants, and begged of him to record his opinion on their growth and qualities, with reference to their age, and his experience of the plant in Assam. The result was quite satisfactory. Encouraged by this result, I determined to give an extended trial to the plant, and through the kindness of Major Jenkins and Captain Brodie, of Assam, I procured a supply of fresh seed in October and November last, which was planted in November and the early part of December.
