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.
