Every citizen of the republic ought to consider himself an unofficial policeman, and keep unsalaried watch and ward over the laws and their execution.
Mark TwainEvery improvement that is put upon the real estate is the result of an idea in somebody's head. The skyscraper is another idea; the railroad is another; the telephone and all those things are merely symbols which represent ideas. An andiron, a wash-tub, is the result of an idea that did not exist before.
Mark Twain
