Thomas Jefferson (1785)

A country whose buildings are of wood, can never increase in its improvements to any considerable degree. Their duration is highly estimated at 50 years. Every half century then our country becomes a tabula rasa, whereon we have to set out anew, as in the first moment of seating it. Whereas when buildings are of durable materials, every new edifice is an actual and permanent acquisition to the state, adding to its value as well as to its ornament.
