(ENEF, Ecole nationale des eaux et forêts, Nancy (FRA), 1929)THE COMMENCEMENT OF THE TEACHING OF FORESTRY IN FRANCE - After the disturbed days of the Revolution and of the Empire, it was found advisable to reestablish the Forest-Service in France; and the need appeared, of the foundation of a school in which would be trained the officers of this service. It was then decided, in 1824, to open a school of Forestry in Nancy, in the vicinity of the silver fir forests of the Vosges, of the beautiful broadleaved crops of the Alsacian plain and in the middle of the coppices with standards of Lorraine. The first Director and Professor of forestry in the new school was an Alsacian, Bernard Lorentz, born at Colmar in 1775.For seven years, Lorentz belonged to the forest-service of the provinces, — French at that time, — of the leftbank of the Rhine and thus had the opportunity of making a thorough study of the works of the German foresters, just issued, and specially of the famous treatises of Georg-Ludwig Hartig.There was no complete work on forestry at that moment,in France, and Lorentz had to improvise his teaching and to have recourse to the German publications, at least in the beginning. Lorentz was a professor at Nancy from 1825 till 1830.The object of Mr. Huffel's account, is to expose the evolution of the teaching during these six years. It shows all what had been borrowed to G. L. Hartig by the first professor of forest science at Nancy and what was the celerity with which Lorentz succeeded in creating an entirely original doctrine, well fit to the natural and economical conditions of France. The lectures from 1825 to 1929 which Lorentz drew up in writing, are carefully analysed in Mr. Huffel's review, the second part of which contains a detailed account of the practical work accomplished by the pupils of the royal forestry school from 1825 to 1830.There are studies on topography, management and reports on surveys and especially on the forest survey which Mr. Lorentz directed in the forests on the two slopes of the lower Vosges where he had the opportunity of exposing his views on the selection system of the silver- fir. This survey ended by a visit to a broadleaved forest of the Alsacian plain, at Haguenau, in which Lorentz showed to his young students an oak 2 m 40 in diameter at breast-height, still young and vigorous and which he presumed to be at least 500 years old....

(ENEF, Ecole nationale des eaux et forêts, Nancy (FRA), 1929)I. — The period 1924-1927 has been marked out in the East of France by heavy attacks of Bupalus piniarius L. (Lepidopt. Geometridae) in the pine-forests of Haguenau and of Dasychira pudibunda L. (Lepidopt. Lymantriidae) in the broad-leaved forests. B. piniarius was particularly prejudicial.— Followed by Myelophilus piniperda (Coleopt. Ipidae), it determined, at Haguenau only, untimely fellings of 35.000 cubic-meters. II. — At the end of September 1927, a bacterium which contaminated the larvae of D. pudibunda, has been isolated. —This germ presented some resemblance with a bacillum, parasite on Schistocerca, isolated and described by D'HÉRELLE, and on which trials were made to destroy these Insects. The bacillum parasite on D. pudibunda larvae, interesting at a theorical point of view, seemed to be difficult to use practically. III. — In the forest of Haguenau, another way of destruction was adopted : an aircraft, loaded with pulverulent calcium arsenate, poured the poison on the crowns of the injured crops. — Inspite of the gropings impossible to avoid at the start of such a new method, this process, already employed abroad several times, seems apt for doing a good service....

(ENEF, Ecole nationale des eaux et forêts, Nancy (FRA), 1929)RÉSUMÉ DES PRÉCAUTIONS A PRENDRE CONTRE LES CHAMPIGNONS DES MAISONS. Les précautions préventives essentielles à prendre pour se protéger contre les champignons des maisons sont les suivantes : 1° Employer des bois secs dont l'origine ne soit pas suspecte ; 2° Renoncer à l'emploi de tous matériaux susceptibles de servir de véhicules aux spores ou aux filaments du champignon ; 3° Isoler les fondations et les sous-sols le mieux possible des planchers du rez-de-chaussée ; 4° Éliminer toutes causes d'humidité surtout lorsqu'elle est associée, soit à un dégagement ammoniacal, soit à un air confiné ; 5° Pratiquer une ventilation énergique et judicieuse ; 6° Traiter les bois par des antiseptiques phénoliques convenables....

(ENEF, Ecole nationale des eaux et forêts, Nancy (FRA), 1929)RÉSUMÉ DES PRÉCAUTIONS A PRENDRE CONTRE L'ÉCHAUFFURE DU BOIS DE HÊTRE - S'efforcer en tout cas de sortir aussi rapidement que possible les bois de forêt. Effectuer, si possible, le débit avant le commencement de l'été et assurer convenablement la dessiccation des pièces débitées. Si l'on doit conserver longtemps le bois en grume, faire badigeonner avec un liquide antiseptique (de préférence avec du carbonyle) les découpes et parties où l'écorce est arrachée, dès l'abattage. Rafraîchir d'abord à la hache ou à la scie la surface d'abattage de la grume, de manière à supprimer les arrachements causés par la chute de l'arbre. Appliquer avec un large pinceau assez mou, le carbonyle transporté dans un seau à anse et préalablement tiédir. Faire le badigeonnage avec soin, à plusieurs reprises, pour assurer une pénétration efficace. Le carbonyle étant assez inflammable, le faire chauffer seulement sur la cendre chaude ou au bain-marie. Ce produit étant de plus assez irritant, le manier avec assez de précaution et prendre garde notamment de toucher le visage et les parties délicates de la peau avec les mains présentant des taches de carbonyle. A l'arrivée sur le chantier, badigeonner à nouveau les parties où l'écorce a pu être enlevée dans le transport. Surveiller la dessiccation des grumes, qui doit être assez lente et régulière, de manière à éviter la formation de fissures profondes....
