The second and better know'u devastation of forests by an in- 

 sect was that of the Nun or Spruce ^loth which aj)peare(l ovei* 

 considerable areas of the spruce forests in southern (lermany in 

 IS!)1 and 02. Bavaria alone spent over three hundred and 

 seventy-live thousand dollai-s in combating this insect and finally 

 li.\ I he use of bands or rings of viscous tar on the trees prevented 

 the upward movement of the larvae from the ground and thus 

 the jtest was destroyed, rjreat areas of forests were clear cut 

 ami (he market was glutted Avith spruce poles and logs of certain 

 sizes. Dr. Endres, the great forest statistician of Munich, re- 

 l)orts that even though there w'as an api)ar(Md over-sny)ply of 

 tind)er from these clear cuttings, yet the market did not suffer 

 and a good avei-age price was received for all material. The 

 methods followed in lOurope for condiating either ins(^ct or fun- 

 gous ])ests are hai-dly ai»plicalde here because of theii- densei- 

 population, cheaper labor and smaller and more accessible for- 

 est areas. 



3Iuch was accomi)lis]ied in Uavaria and the states of south- 

 W(»stern Oernmny by (lie chnir cutting of (he. forests in broad 

 sti'i])s. In re])lanting these strips some attem])t was made to 

 re])lace the s])ruce by species not susceptible to injury by the 

 modi. This, however, was not followed out to any large extent, 

 becanse the spruce is the most profitable tree for southern Oer- 

 many. I believe that no system we may nse in wi]>ing ou( (his 

 chesdiut disease, if we are able to do it, will preclude the use of 

 chestnut in our future forest management. The forester is going 

 to grow the tree from which he can make the most money, if the
