The exsiccating forest might here actually be followed in all its phases. It is a pervading trait which I noticed everywhere, especially near the limits of the forest area, that the forest is falling into decay and disappearing over stretches where it was formerly prevalent, and this fact shows us more plainly than anything else that also at this day climatic changes are proceeding and that the forest here is doomed. It is the last desperate fight of the forest against an enemy of superior strength, the deadly drought, of which we are witnesses here. Soon its last remains vanish here, and the open, dry steppe scenery begins to prevail. Thus, there is now no stable relation in the floral conditions of these places. These facts, which are obvious in so many places and in so many different condi- tions, carry evidence, in my opinion, that at present, in the interior of Asia, a climatic change towards a drier (and possibly also hotter?) time is proceeding, and hereby an acceptable explanation may also be found why the forest — especially in the lower and accordingly drier regions — has so much difficulty in invading areas again from.
