170 CEMENT AND CONCRETE 



Instructions: 



1) Describe a circle the exact size of top desired on a 

 smooth level place on the ground. 



2) Carefully excavate inside of the circle to a depth of 4". 



3) Cut out a cylindrical wood block and locate where 

 pump pipe will pass through. 



4) Provide four bolts to fasten pump to top. 



5) Cut two pieces of hog wire for reinforcing across top, 

 and two pieces of large, smooth wire for the edge. 



6) Mix concrete of 1 : 2 : 3 proportion to a quaky con- 

 sistency. 



7) Sprinkle form so it will not absorb water from con- 

 crete. 



8) Place concrete in bottom half of form. 



9) Place reinforcing and set bolts in place. 



10) Fill form with concrete. 



11) Build up concrete where pump is to stand. 



12) Finish surface with slight slope toward one side so 

 water will drain off. 



13) Sprinkle top from day to day. Remove at the end of 

 a week or ten days.
