distribution recalls the Subtropical rains, diminishes on the other 
side of the chief range of the Caucasus in Baku to 13-4, in Der-

vapors ; hence from Africa to the interior of Asia in the direction 
of SW to NE, there lies a waste tract, in which the evapora- 
tion exceeds the fall of rain; consequently, the level of the inte-
