levees are constructed, following contour lines, at every

 running of contour lines, levee construction, and leveling. 

 Levees of black adobe soil permit more seepage than 

 those made of other types of clay. Levee construction 

 and the prompt delivery of water are of the greatest 

 importance. Payment for water should be based upon
