How often is this operation repeated?

Two or three times, the furnace each time being made less hot.  The tea is then placed in the store-houses, or packed in chests, and sent to most of the countries in Europe and America.

Describe the appearance of the Tea-tree.

The Tea-tree when arrived at its full growth, which it does in about seven years, is about a man’s height; the green leaves are narrow, and jagged all round; the flower resembles that of the wild rose, but is smaller.  The shrub loves to grow in valleys, at the foot of mountains, and on the banks of rivers where it enjoys a southern exposure to the sun; though it endures considerable variation of heat and cold, as it flourishes in the northern clime of Pekin, where the winter is often severe; and also about Canton, where the heat is sometimes very great.  The best tea, however, grows in a temperate climate, the country about Nankin producing better tea than either Pekin or Canton, between which two places it is situated.

What produces the difference between Green and Bohea, or Black?

There are varieties of the plant, and the difference of the tea arises from the mode of preparation.

What nation first introduced it into Europe?

The Dutch in 1610; it was introduced into England in 1650

What is Coffee?

The berry of the coffee-tree, a native of Arabia.  The coffee-tree is an evergreen, and makes a beautiful appearance at all times of the year, but especially when in flower, and when the berries are red, which is usually during the winter.  It is also cultivated in Persia, the East Indies, Liberia on the coast of Africa, the West Indies, Brazil and other parts of South America, as well as in most tropical climates.

     Tropical, being within the tropics, that is, in the Torrid
     Zone.

Who was the original discoverer of Coffee, for the drink of man?

It is not exactly known:  the earliest written accounts of the use of Coffee are by Arabian writers in the 15th century; it appears that in the city of Aden it became, in the latter half of that century, a very popular drink, first with lawyers, studious persons, and those whose occupation required wakefulness at night, and soon after, with all classes.  Its use gradually extended to other cities, and to those on the eastern shores of the Mediterranean.  Towards the end of the seventeenth century, it was carried to Batavia where it was soon extensively planted, and at last young trees were sent to the botanical garden at Amsterdam.

Who introduced it into France and England?

Thevenot, the traveller, brought it into France, and a Greek servant named Pasqua (taken to England by Mr. Daniel Edwards, a Turkey merchant, in 1652, to make his coffee,) first set up the profession of coffee-man, and introduced the drink among the English.
