Fernow says, in a review of the work of the Department of Forestry, different methods of cultivation from those given in the humid parts are necessary, and the plant material has to be selected with a view to a rigorous climate characterized by extreme ranges of temperature varying from -40° to +120° F. The requirements of the plants for moisture must be of the slightest, and they must be capable of responding to the demands of evaporation. At first, whatever trees will grow successfully from the start under such untoward conditions would have to be chosen, no matter what their qualities otherwise might be. The first settlers have ascertained by trials some of the species that will succeed under such conditions, but unfortunately most of them are of but small economic value, and some of them are only short-lived under the conditions in which they have to grow. A few years ago Mr. Fernow came to the conclusion that the conifers, especially the pines, would furnish more useful and otherwise serviceable material for the arid regions. Besides their superior economical value, they require less moisture than most of the deciduous trees that have been planted, and they would, if once established, persist more readily through seasons of drought and be longer lived. A small trial plantation on the sand hills of Nebraska lent countenance to this theory. It being vastly more difficult to establish the young plants in the first place than in the case of deciduous trees, much attention was given to the provision for protection of the seedlings from sun and winds; and they were planted
