Tibet is on the whole increasing, is a question for the traveller 
rather than for the closet botanist, but there is no doubt that if 
there is an increase in one place there is temporary or permanent 
destruction in other places, due to the shifting sands. 
BIBLIOGRAPHY. 
This bibliography is not put forward as complete, but it 
comprises, it is believed, all sources of information, and it also 
includes some works from which little or nothing was extracted, 
but which may be of service to persons interested in carrying 
their investigations further.
