Source: Webster's dictionaryAll Nature's wildness tells the same story: the shocks and outbursts of earthquakes, volcanoes, geysers, roaring, thundering waves and floods, the silent uprush of sap in plants, storms of every sort, each and all, are the orderly, beauty-making love-beats of Nature's heart.
