358 ECONOMY OF THE FOREST. 



On this latter brancli of the subject, the management of the 

 primitive wood, experience and observation have not yet collected 

 a sufficient stock of facts to serve for the construction of a com- 

 plete system of this department of sylviculture ; but the govern- 

 ment of the forest as it exists in France — the different zones and 

 climates of which country present many points of analogy with 

 those of the United States and of some of the British colonies — 

 has been carefully studied, and several manuals of practice have 

 been prepared for the foresters of that empire. I beheve the 

 Cours Elementaire de Culture des Bois cree d VEcole Forestiere 

 de Na/ncy, jpa/r M. Lorentz, complete et publie pa/r A. Pa/rade, 

 with a supplement under the title of Cours d^ Amenagement des 

 Forets, par Henri N'oMquette, has been generally considered the 

 best of these. The Etudes sur VEconomie Forestiere, par Jules 

 ClamS, which I have often quoted, presents a great number of 

 interesting views on this subject, but it is not designed as a prac- 

 tical guide, and it does not profess to be sufficiently specific in 

 its details to serve that purpose.* JSTotwithstanding the differ- 

 ence of conditions between the aboriginal and the trained forest, 

 the judicious observer who aims at the preservation of the former 

 will reap much instruction from the treatises I have cited, and I 

 beheve he will be convinced that the sooner a natural wood is 

 brought into the state of an artificially regulated one, the better 

 it is for all the multiplied interests which depend on the wise 

 administration of this branch of public economy. 



* Among more recent manuals may be mentioned : in French, Les ^tudea 

 de Maitre Pierre, Paris, 1864, 12mo ; Bazelaike, Traite de Rehoisement, 2d 

 edition, Paris, 1864 ; Paston, L' Amenagement des Forets, Paris, 1867 ; in 

 English, Gregor, Arboriculture, Edinburgh, 1868 ; in Italian, Siemoni's very 

 valuable Manuale teorico-pratico d'Arte Forestale, 2d ediz., Firenze, 1872 ; the 

 excellent work of Cerini, Dei Yantaggi di Societd per I'Impianto e Oonser- 

 vazione dei Boschi, Milano, 1844, 8vo ; and the prize essay of Megtjscher, 

 Memoria sui Boschi, etc., 2d edizione, Milano, 1859, 8vo. Another very im- 

 portant treatise on the uses of the forest, though not a manual of sylviculture, 

 is ScHLEiDEN, FUr Baum und Wald, Leipzig, 1870 ; and Ntjtzhgrn, Skovog 

 Land, Kjobenhavn, 1873, is a valuable work of the same general character. 

 Much important and practically useful matter is also to be found in Beports 

 on Forest Management, by Capt. Campbell Walker, 8vo, London, 1873, and in 

 The Cultivation of Timber and the Preservation of Forests, a Keport from the 

 Committee on the Public Lands to the House of Representatives, March 17, 

 1874.
