Evergreen trees produce an effect in ornamental planting not to be obtained in any other way. It is inexpressible how much they add to the beauty and comfort of a country residence at all seasons of the year, particularly in the winter months, when other trees are stripped of their foliage. The advantages resulting from the planting of Evergreens are many and a most beautiful effect may be obtained by the judicious arrangement of varieties of different colors that will harmonize with the deciduous and flowering trees and shrubs you may have planted on your place. No one can help admiring the cheerful and comfortable appearance of the homes of those who have improved their grounds with the planting of Evergreens. In no other tree is so great care required in digging and transplanting as in the Evergreen The great loss of so many Conifers is caused by exposing the roots to the sun and wind at times of removal and setting. Great care should be exercised in these matters if we expect good results. Evergreens require to be handled and planted very carefully as they are extremely sensitive to injury by drying; their roots should never get dry while out of the ground.
