Utah, like other states in the arid region of the United States, points with just pride to her present and future agricultural developments. She proudly boasts, and no doubt justly too, that her fields of green vegetation are inexhaustible and always expanding, and with due vigilance and care on the part of her land holders these fields will bring forth the proper supplies for man for an indefinite period. But, like her neighboring sister states on the east, west, north, and south, she realizes that the precipitation over her lands, as a general rule, is insufficient for the growing and maturing of crops. As a result, her principal lands can only be made to bear crops through the assistance of irrigation. In all irrigation, next to the land itself, the most important factor to be considered is the water supply.
