454 WEST VIRGINIA EXPERIMENT STATION. 



Owing to technicalities regarding the funds appropriated for 

 printing the bulletins of the station, the printing of this report 

 was all done while the author was conducting investigations for 

 the U. S. Department of Agriculture in the forests of the North- 

 west; hence it was not possible for him to see the proof.
