FOREST BOTANY AND FORESTRY 



Raphael Zon, Editor 



1. Gtjyot, Ch. Jurisprudence. [Legal affairs.] Rev. Eaux et Forets 57: 60-62. 1919. — 

 The decree of November 26, 1918, regarding the application of the law of July 2, 1913, provid- 

 ing that private owners may voluntarily place their forest lands under management by the 

 State, offers hope that the law will be administered in a liberal spirit, and that local forest 

 officers will not be too bound clown by rigid regulations. It is to be hoped that the amounts 

 received from private owners to pay for the management of their lands by the State will be 

 largely or entirely turned over to the local forest officers to recompense them for the additional 

 work entailed by the law. — S. T. Dana. 



2. Doe,Fr. La conversion en futaieetl'oidium. [Conversion into high forest and the oldium]. 

 Rev. Eaux et Forets 57: 53-59. 1919. — The fungus oidium appeared in several departments of 

 the Province of Champagne about 1907. Several species are affected but particularly oak. 

 The spread of the disease is favored by humidity, especially in the spring when vegetation is 

 starting. Young trees are most seriously affected, particularly coppice shoots of the current 

 year. These are killed back year after year until they finally succumb. Seedlings, in spite 

 of the theory as to their superior vigor, suffer equally if not worse. No remedy for the disease 

 has yet been discovered. — This new enemy threatens to make the conversion of coppice stands 

 into high forests, already sufficiently difficult, entirely impracticable. The advisability of 

 this system of forest management, which has recently been in considerable favor in France, is 

 also questioned by the author on other grounds. In his judgment if oak is to be grown at all 

 in the region with which he is familiar, the system of coppice under standards will have to be 

 used. Until sentiment on this point crystallizes he advises doing away with reproduction cut- 

 tings or making them as light as possible. — S. T. Dana. 



3. X. L'Administration des eaux et forets pendant la guerre. [The administration of waters 

 and forests during the war.] Rev. Eaux et Forets 57 : 45-52. 1919.— At the outbreak of the war 

 the bulk of the personnel attached to the Administration of Waters and Forests joined the vari- 

 ous services in the army, leaving barely a sufficient force for the administration of the French 

 forests. As the demands for wood for military purposes gradually but steadily increased, 

 each service in the army proceeded to satisfy its own needs with no regard to the action being 

 taken by other services or to the future of the forests. Seeing the danger to the forests in this 

 method of exploitation, the Minister of Agriculture succeeded in securing the establishment 

 of an Army Forest Service (Service forestier d'Armee) which exercised general supervision 

 over all utilization of the forests within the zone occupied by the army. Back of the lines
