Fic. 3. 



The dam should be not less than eight feet wide on top, and have a slope of 

 two to one on each side. That is, for each foot in height it should have a width 

 of two feet. A dam ten feet high and 8 feet wide on top would be 48 feet wide 

 at the base. The spillway or overflow should be constructed at one end of the 

 dam as indicated.
