of nature are interdependent. It is not 

 enough that we have the evaporation of mois- 

 ture that will ascend into the higher regions of 

 the air and there be condensed into cloud and 

 possibly rain, but we must have the means for 

 distributing these conditions over a large area, 

 and for this purpose we have the phenomenon 

 of wind. Why the winds blow can be ac- 

 counted for to a certain extent, we might say 

 to a large extent, but there yet remain many 

 unsolved problems relating to wind and 

 weather. Of the phenomena of wind we will 

 speak more fully in a future chapter.
