species Quercus rubra and Q. palustris less severelj' than the European species 

 Q. tozza, Q. pedunculata, and Q. ccrris, has recently shown increased activity on

The fight against dry rot of pine and fir trees, A. Moller (Ztschr, Forst

 reported (E. S. R., 23, p. 653), the author states that results of his recent 

 studies involving infection of pine and fir with Trametes pini support the claim 

 of Hartig (E. S. R., 7, p. 512) to the effect that the dry rots of these conifers 

 are due to the same fungus, T. pini.

 Bot., 11 (1913), pt. 1, pp. 106-116, figs. 5).— This article refers to work pre- 

 viously reported (E. S. R., 31, p. 248). MeruHus lacrymans attacked wood only
