Number of Brick Required to Construct any Building.

Facts for Builders. 



One thousand shingles, laid 4 inches to the weather, will 

 cover 100 square feet of surface, and 5 pounds of shingle nails will 

 fasten them on. 



One-fifth more siding and flooring is needed than the number 

 of square feet of surface to be covered, because of the lap in the 

 siding and matching. 



One thousand laths will cover 70 yards of surface, and 11 

 pounds of lath nails will nail them on. Eight bushels of good 

 lime, 16 bushels of sand, and one bushel of hair, will make enough 

 good mortar to plaster 100 square yards.
