STATE AND OTHER FORESTS OF FRANCE.

This working-plan is to be revised in 1905, as the present 

 one has been completely upset by abnormal windfalls, in one 

 year 898,045 cubic feet having been blown down in the first 

 working-section, and 319,655 cubic feet in the second. 



This furnishes another proof of the unsuitability of the shelter- 

 wood compartment system for mountain forests, and shows that 

 reversion to a modified selection system is necessary.
