Mission Crafts and Technologies

1. How long did it take to construct a mission and were craftspeople brought to the missions to help with the construction of the missions?

2. Did  the  Indians  or  Spanish  devise  the  hydraulic  system  for  the  mission?  Was  this  a  new innovation  for  both  peoples?  How  did  this  water  system  impact the Indians and the Spanish lifestyle and agricultural landscape?
