Green teas do not grow in the same place as the Bohea tea. They are brought from the province of Nankin, and are distinguished into three sorts. The first is known under the name of songlo tea, but oftener under that of green toukay; the second is called bing tea; and the third hays-suen tea, or hyson. There are also some other kinds, but the greater part of them are unknown, or of little importance to foreigners.

The songlo and hayssuen teas come from the same shrub; their only difference is in the manner of their being prepared. Bing tea grows on a different shrub, the leaves of which are thicker and larger than those of other kinds. All teas ought to have a green leaden tint: the older they are, the leaves become more yellow, which is a very great fault. They ought also to have a burnt or scorched smell, not too strong, but agreeable; for when they have been long kept, they have a filthy smell, somewhat like that of pilchards. The French wish to find in green teas, and particularly in songlo and imperial, an odour similar to that of soap. In these several kinds of tea, there is a particular distinction to be made, as they are generally classed into one, two, or three kinds, according to the periods at which they were gathered.
