          sizeable rewards. In Spain they dug broad canals,
        
        
          and then subdivided them, with the result that the
        
        
          arid plain of Valencia was turned into a vast tract of
        
        
          lush green. They established a permanent
        
        
          department of irrigation, which supplied all kinds
        
        
          of relevant information.
        
        
          Describing Muslim Spain, Bertrand Russell writes:
        
        
          One of the best features of the Arab economy
        
        
          was agriculture, particularly the skillful use of
        
        
          irrigation, which they learnt from living
        
        
          where water is scarce. To this day Spanish
        
        
          agriculture profits by Arab irrigation works.

          It is a fact that the Muslims who went to Spain
        
        
          brought about a veritable green revolution. There
        
        
          they established such irrigation systems for fields
        
        
          and orchards as were unprecedented in history.
        
        
          However, strangely enough, Bertrand Russell
        
        
          attributes this to their having lived in the past in
        
        
          desert areas, where water is scarce. This explanation
        
        
          is meaningless. The true, underlying cause of this
        
        
          feat is the monotheistic revolution, which had
        
        
          overhauled the minds of Arabs. Prior to this, people
        
        
          had seen rivers, springs, and the sea in the form of
