has proved very susceptible. Hence, the danger of smoke dam- 

 age is another argument for the mixed stand. As a rule the 

 hardwoods seem more resistant than the conifers. Very little 

 advance has been made in devising effective means of dissipating 

 the noxious gases so that the smoke problem is likely to remain 

 a subject of concern to foresters.

The loss from the Nun Moth in Saxony 



„ „ first became serious in 1909. Prompt 



measures were at once taken in the state 

 tfv 

 _ forests and the destruction of the butter- 



^' flies and lining of the tree produced excel- 



lent results. Unfortunately nothing was 

 done in the communal and private forests until some time after 

 the government started preventive measures. Consequently the 

 loss was greater than it should have been. The artificial methods 

 employed, however, were not nearly so effective as the natural 

 enemies of the Nun Moth in finally reducing the damage done. 

 Among these the diseases of the caterpillars (flacherie) has been 

 most deadly. 



The main lessons to be drawn is the need for concerted action 

 against insect enemies. While the Saxon state officials were 

 doing all they could the private and communal forests were not 

 properly handled. Furthermore, the neighboring state, Prussia, 

 declared preventive measures to be useless.
