Marcll.~\ GREEN-HOUSE REPOTTING. 257 



coss is repeated two or three times, or oftener, before the tea 

 is put into the stores, in order that all the moisture of tho 

 leaves may be thoroughly dissipated, and their curl more com- 

 pletely preserved. On every repetition the pan is less heated, 

 and the operation performed more closely and cautiously 

 The tea is then separated into the different kinds, and depo- 

 sited 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 winnow- 

 ing the tea, the leaves are taken up in succession as they fall ; 

 those nearest the machine, being the heaviest, are the gun- 

 powder 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." 



Kaempfer asserts that a species of Camellia as well as Olea 

 Frcigrans is used to give it a high flavour. 



Tacsbnia, a genus of plants much resembling Passifloras, 

 both in flower and habits. T. pimiatistipulata 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.) 



Trop&dlum, 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 delicate 

 shoots on a wire trellis, or small twigs of branches stuck in 

 the pots. T. tricolorhm, T. tricolorum superbum, and T. 

 pentaphyllum have beautiful scarlet flowers marked with yel- 

 low and black, and are superb and lovely when in bloom. T 

 hrachyseras has yellow flowers. (Soil No. 10.) 



Verbena. The beauty of the green-house in spring and 

 the flower-garden in summer is greatly augmented by the 

 late introduction of this lovely family of perpetual flowering 

 plants. There are among them every shade of colour, from 

 the richest scarlet to the purest white, and in addition to the 

 beauty and profusion of their flowers, several of them are ex- 

 quisitely scented. V. cham&dri/fdlia, or melindres, was the 

 first scarlet species introduced, and it is yet pretty.
