600 FOREST CULTURE AND 
geologic rock-formations of various ages. But how 
rarely are such advantages attainable in one area! 
Local climatic influence will also frustrate largely cult- 
ural successes, without costly artificial means for imi- 
tating the conditions on which the growth of many a 
plant entirely depends. Few botanic gardens have, 
in this regard, the rare facilities of the one of Buit- 
enzorg in Java, which, in its several branch establish- 
ments on the slopes ofa high mountain-range, enjoys 
the means of bringing to perfection as well species 
bathed in the vapors of the hottest tropical jungles’ 
as also such as only prosper on alpine heights, or such 
forms of vegetation as withstand the vehemence of 
iey storms or the rigor of protracted burials under 
snow, and all this in acomparatively close proximity. 
When an important plant has once been introduced 
or tested, a task in which a botanic garden must al- 
ways take a leading share, then rural enterprise and 
private capital are expected to advance the cultivation 
and utilization of such a plant to commercial dimen- 
sions; or in particular cases, the State may fairly aid 
by affording the necessary special means for success- 
fully establishing such a plant as a new source of 
wealth to the country. I wish we could here do for 
the Tea-plant what the governments of British and 
Dutch India have done for the formation of Cinchona 
plantations in the warm, temperate regions of the 
Indian mountains. The officiating Director of the 
Botanic Garden of Calcutta, C. B. Clarke, Esq., M. A., 
gives, in hisreport of April of this year, the number 
of Peru Bark plants in the Bengal Government plant- 
ations as 1,741,474, irrespective of seedlings and cut- 
tings in the nursery plantations. The established
