contain from five to twenty small furnaces, about three feet 
high each, having at top a large flat iron pan. There is also 
a long low table covered with mats, on which the leaves are 
laid, and rolled by workmen, who sit around it : the iron pan 
being heated to a certain degree, by a little fire made in the 
furnace underneath, a few pounds of the fresh-gathered leaves 
are put upon the pan ; the fresh and juicy leaves crack when 
they touch the pan, and it is the business of the operator to 
shift them as quickly as possible, with his bare hands, till they 
cannot be easily endured. At this instant he takes off the 
leaves with a kind of shovel resembling a fan, and pours them 
on the mats before the rollers, who, taking small quantities at 
a time, roll them in the palms of their hands in one direction, 
while others are fanning them, that they may cool the more 
speedily, and retain their curl the longer. This process is 
repeated two or three times, or oftener, before the tea is put 
into the stores, in order that all the moisture of the leaves may 
be thoroughly dissipated, and their curl more completely pre- 
served. On every repetition the pan is less heated, aud the 
operation performed more closely and cautiously. The tea is 
then separated into the different kinds, and deposited in the 
store for domestic use or exportation. 
" The different sorts of black and green arise not merely 
from soil, situation, or the age of the leaf; but after win- 
nowing the tea, the leaves are taken up in succession as they 
fall ; those nearest the machine, being the heaviest, are the 
gunpowder tea; the light dust the worst, being chiefly used 
by the lower classes. That which is brought down to Canton 
then undergoes a second roasting, winnowing, packing, &c, 
and many hundred women are employed for these purposes." 
Kamipfer asserts that a species of Camellia as well as Olea 
Fiai/rans is used to give it a high flavour. 
Tacsdriia. a genus of plants much resembling Passifloras 
both in flower aud habits. T. pinnatistipulata and T. mollis, 
when planted into the ground and trained up the rafters of 
the green-house, make a pretty appearance with their profu- 
sion of rosy blush-coloured flowers. (Soil No. 13.) 
Tropeeolum, a genus of generally delicate-growing plants, 
principally from South America. They require nicety of 
treatment to bloom them well, unless a large bulb can be 
procured, when it may be planted in a sev^n-inch pot, and 
will then flower without farther care by training their deli- 
cate shoots on a wire trellis, or small twigs of branches stuck
