   Keyline does not waste water. Full effort should be made to hold all rain water that falls on the property, so water storages, designed and fitted to the climate and the land shape, become permanent features. These farm irrigation dams, with their lowcost water readily available for quick irrigation, make property improvement continuous and repeatedly profitable. All the dams are constructed with lockpipe control ("Yobarnie" and "Nevallan").

   The full development of farm water storage, together with the further improvement of all Australian soils, are our greatest sources of potential wealth.

   Since the additional capital potential runs into the thousands of millions of pounds from farm water storage alone, expansion of this work dwarfs into insignificance all other schemes for the immediate development of our national economy. Not only is the scope for this type of development so very considerable, but it is also the easiest to finance.
