 comparatively oaoy to tell from external appearances v?hon a 

 tree ie aifoctod with either of tho first tvro disoaoos

 harder matter, uinco tho fruiting bodies of tho fungus do not 

 remain on tho tree long end aro rarely ovor apparent in the

 hole left in tho bark of the tree which results frow the 

 breaking off of the fruiting body. When this is detected it 

 iu of course a euro cign thivt tho tree is rotten. A pro- 

 llninery study oonduotod in tho Stanislaus Forest this spring 

 by Dr. E. P. Uelnecko tends to load to tho conclusion that 

 ir. tho locality studied dry rot Is roost frequently found in 

 trees over .26 Inches In diameter. Diseosod trees should be 

 removed because they spread diseaeo and firo scarred trees 

 because the? aro v;oc',;onod and thoroforo raa'co but clovr f;rov,*th

 bunches of pitch filled rlth sardust v/hich appear on bho bark 

 at the point where tho insect went into tho troo.
