The tea-plant has been successfully cultivated, on a large scale, in the island of Madeira, at an elevation of 3,000 feet above the level of the sea, by Mr. Hy. Veitch, British ex-Consul. The quality of the leaf is excellent. The whole theory of preparing it is merely to destroy the herbaceous taste, the leaves being perfect, when, like hay, they emit an agreeable odor. But to roll up each leaf, as in China, is found too expensive, although boys and girls are employed at about two-pence or three-pence per day. Mr. Veitch has, therefore, tried the plan of compressing the leaves into small cakes, which can be done at a trifling expense. It is performed when the leaf is dry; whereas, the rolling requires moisture, and subsequent roasting on copper plates is necessary to prevent mustiness. In this process the acid of the tea acts upon the copper, and causes that astringency which we remark in all the China teas. The tea of Cochin China is considered inferior to that of China, being less strong and pleasant in flavour. An inferior sort of tea, with a leaf twice or thrice as large as that of Bohea, grows wild in the hilly parts of Quang-ai, and is sold at from 12s. 6d. to 40s. the picul of 133lbs. The Dutch have devoted much attention to tea cultivation in Java, and the plantations are in fine order. Nearly a million lbs. of tea were shipped thence in 1848; but the tea is said to be of inferior quality, and grown and manufactured at considerable expense. Japan produces both black and green tea. The Japanese prefer the latter to the Chinese green tea. The black tea is very bad. The Japanese tea-tree, is an evergreen, growing in the most sterile places to the height of about six feet. It is described as above, by Koempfer, as having leaves like the cherry, with a flower like the wild rose; when fresh, the leaves have no smell, but a very astringent taste. Tea grows in all the southern provinces of Japan, but the best green is produced in the principality of Kioto, where it is cultivated with great care. A few years ago, Messrs. Worms attempted the cultivation of tea in Ceylon. The island, however, lies too far within the tropics to offer a climate like Assam, which is situate without them. The plants may thrive to appearance, but that is not a demonstration of their quality. The tea-plant has reached upwards of six feet in height at Pinang, and in as healthy a state as could be desired, but the leaf had no flavor, and although thousands of Chinese husbandmen cultivate spices, and other tropical productions on that island, no one thinks it worth while to extend the cultivation of the tea-plant in Pinang. The Chinese there laugh at the idea of converting the leaf into a beverage.
