Land
Land is legally defined as the surface of the earth, all that is above it, and all that may be below. However, Sir Charles Fortescue Brickdale, 1913, gave a classical definition as follows: "Land is the place of all shelters in the city, the town, the village and the home. It is the source of food, of materials for construction and manufacture, of coal, gas and oil, of springs and rivers and other essentials for life, indestructible, immovable, it is the foundation of all human activity. Houses and factories, forests and farms, rivers, roads and railways, mines, quarries and reservoirs are all fashioned from the land. It offers endless opportunities for development and discovery. It is the ultimate source of wealth."
