2 IRRIGATION ENGINEERING IMAGES

Herbert M. Wilson, Irrigation Engineering, John Wiley and Sons, 1909.

1. Meaning of Irrigation.—The word irrigation implies a condition far more imposing than is intended. In dry weather a watering-pot is used to sprinkle such plants and flowers as are considered most valuable, or perhaps a hose or water-barrel is used to moisted more or less of the garden truck. This is irrigation pure and simple. The only difference between this form and that more generally implied by the word irrigation as used in arid lands is that in the latter the application of water to crops becomes a business, and the farmer and the engineer unite in the employment of the methods whereby water may be applied in the easiest, least expensive, and most certain manner.
