Now, all we say is this: "In future you must pay one halfpenny in the pound on the real value of your land. In addition to that, if the value goes up, not owing to your efforts-if you spend money on improving it we will give you credit for it-but if it goes up owing to the industry and the energy of the people living in that locality, one-fifth of that increment shall in future be taken as a toll by the State."
