"Oaklanders had never a better opportunity than now, for beautifying their lawns and gardens with the choicest of trees and ornamental shrubbery. Amongst those who have the means and the inclination to adorn their grounds, may be mentioned the name of Horatius Livermore, whose charming suburban retreat of "Rock Ridge Park," is so appropriately named. A city nurseryman, has been engaged lately in setting out in these grounds, one thousand trees, consisting of the eucalyptus, that gem of Australia, walnut, sycamore, laurel and oak, besides shrubs of rare varieties."
