Note 7 — FRANCE.

In this statement we follow Clavé and other authors. Huffel takes exception to this conception of the origin of the shelterwood system, because he finds in some documents allusion to a modified application of the tire et aire method which might be construed into shelterwood regeneration. Indeed, Guiot (1770) and Varennes de Fenille (1790) describe methods of procedure which resemble somewhat this method of regeneration. But as the method of successive fellings was practised in Germany since 1720, and fully developed in all its detail by 1790—Hartig formulating merely into rules what was long practised—it is likely that the French authors had heard of it. Moreover, in another place (vol. III, p. 271) Huffel says: “At this time (1821) one made several tentative regeneration cuttings by successive fellings according to the new formula—but without success.”
