In commenting upon the enormous yields of fruit in favored localities of Colorado The Irrigation Era says: Irrigation is the cause of full crops every year in that it replaces the mineral elements in the soil that have been taken up by the growing crops. Sunshine, almost perpetual from the time the apple begins to form until it is gathered, gives the fruit such a flavor and color that it readily sells alongside any other apple for doublé the price. Then, too, they are exceptionally free from insects of any character. The trees bear more fruit, baving an abundance of the mineral elemente in the soil that are necessary to produce fruit. It is only a matter of how inuch you leave on the trees, or how much they will bear by putting props under the limbs.
