As the spring comes on, and the densening outlines of the elm give daily a new design for a Grecian urn, โ its hue, first brown with blossoms, then emerald with leaves, โ we appreciate the vanishing beauty of the bare boughs. In our favored temperate zone, the trees denude themselves each year, like the goddesses before Paris, that we may see which unadorned loveliness is the fairest.
