A erat deal has already been said in these chapters 
about the influence of trees on the climate of a country, 
but as some people seem to be sceptical on this subject 
we will add for their benefit a few more facts. 
The formation and development of the forest service 
of India has been followed by a succession of reports 
that bring into prominence the great and varied forest 
resources of that country. 
The work of classifying, demarcating, working, and 
managing was commenced and conducted so recently as 
the year 1863, and hence a thorough examination of the 
forests of India has not been completed. The expanse 
of country under the direct control of the government 
comprises every variety of climate, elevation, and tem- 
perature, and almost every form of soil and sub-soil.
