genera afford respecting the nature of the climate. Part1V is occu- 
© pied with a Comparison between. the climate-of Upper Assam and 
® ~ that of the Tea Provinces of Central China, compiled from the SZ 
perfect observations that have been made. Part V, is an Examina- 
»» tion into the nature of the stations of the Tea-plant in the Province : 
“9 /Kiang-nan and Kiang-see, in which Mr. Griffith contradicts the opin- 
: ion introduced by Abeel, and for a long time prevalent, that the plant 
is a native of, or at least better adapted to, places of considerable ele- 
+e or of such a nature that snow and frost are of common occur- 
rence in the winter months. In Part VI, Remarks on the genus to 
which the Tea-plant belongs, and on the geographical distribution of 
the Indian plants of the same natural order, the author comes to t 
conclusion that the tea-plant and the Camellia belong to the same ge- 
nus. Part VII, which is occupied with Remarks on the plans of Tea 
culture adopted by the Tea Committee, and on a proposed new and 
improved mode of cultivation ; it contains a brief history of the at- 
tempts which have been made to introduce and cultivate the tea-plant 
in India, and of the alleged mistakes which have been committed; it 
is very controversial in its character. 'The author also takes up the 
question whether the green and black teas of commerce are the pro- 
duce of the same species, modified by culture, soil, and mode of pre- 
paration; or whether they are derived from two distinct species. But 
after enumerating the various opinions which have been advanced, he 
leaves this long controverted question exactly where he found it. The 
remainder of the report is chiefly devoted to a detailed consideration 
of the steps which should be followed in the cultivation of the plan 
whether indigenous or imported, and which, in his opinion, would 
render its success certain. ‘This conclusion is adopted on the follow- 
ing grounds, viz:— 
1. That the tea-plant is indigenous to, and distributed extensively 
over, large portions of Upper Assam. 
2. That there is a similarity in configuration between the valley of 
Assam and two of the best known tea provinces of China. ‘ 
3. That there is a similarity between the climates of the two coull- 
tries, both with regard to temperature and humidity. 
. That there is a precise similarity between the stations of the 
tea-plant in Upper Assam, and its stations in those parts of the prov 
inces of Kiang-nan and Kiang-see that. have been traversed by Ew 
ropeans. 
5. That there is a similarity both in the associated and the general 
vegetation of both Assam and those parts of Chinese tea provinces 
situated in or about the same latitude.
