Note DN — PREFACE TO THE EDITION OF 1814 (continued 2)

During the American War of Independence, trees were planted as symbols of freedom. This custom passed over to France. The Jacobins planted the first tree of Liberty in Paris in 1790, and the practice spread rapidly. At each revolutionary period it was revived, and during the Empire again suppressed. A treatise has been written on the custom, by the Abbé Grégoire.—ED.
