82. Camellia Japonica, L. 83. C. Sasanqua, Th.—* The 
* Sasank’wa’ is set in the plantations of tea, at a distance of 
ten or twelve feet between each shrub, with the object of 
sheltering the tender tea leaves from the east wind in spring 
and the burning sun's rays during summer. It is seldom 
that the leaves themselves are collected for tea, but the 
country people assert that the delightful scent of its flowers 
communicates a similar odour and taste to the tea, of which 
the finer sorts are gathered at the period when the Sasank’wa 
is in bloom. So universal is the idea that the tender leaves 
of tea are affected by the smell of neighbouring objects, that 
the persons employed in raising it carefully avoid the vicinity 
of manure heaps, and even wear gloves when gathering the 
imperial tea reserved for the use of the princes and nobles 
the realm. An oil is extracted from Sasank'wa nuts, similar 
to what is produced by the Camellia. - 
The glossy and tufted foliage, with the beauty of its n 
white flowers, the more prized because they blow in winter» 
cause this shrub to be extensively planted round the : 
ings of the rich and wealthy inhabitants of Japan; upwards : 
of twenty varieties are in cultivation. :
