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 oif 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 oftencr, bcfote 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, and the 

 operation performed more closely and cautiously. The tea is 

 then separated into the difi"erent kinds, and deposited in the 

 store for domestic use or exportation. 



" The difl"erent 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.'^ 



Kasmpfer asserts that a species of Camellia as well as 

 Olea Frdgrans is used to give it a high flavor. 



Tacsbnia, a genus of plants much resembling Passifloras 

 both in flower and habits. T. pinnatiatipulata 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-colored flowers. (Soil No. 13.) 



Tropaeolum, 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 seven-inch pot, and 

 will then flower without farther care by training their deli-
