We have come to feel well acquainted with the blue spruce of Colorado through the beautiful blue or silver-leaved specimen trees so common on lawns everywhere we go. It is a cool, crisp-looking tree, of perfect symmetry, the whorls of branches well apart, insuring the full development of leaves and branchlets. It is a disappointment to its owner that the growing tree loses at length its lower limbs and the symmetry of its top. Yet this is a far-off event, and there are years of satisfaction ahead for the buyer of a handsome little blue spruce for his garden. Shrubbery can be tucked in around the tree when it begins to age, and other trees so placed as to hide its shortcomings.
