34793. POPULUSDELTOIDES. 



Cottonwood. From A. Woeikoff, No- 

 vospaska, Russia. As cottonwoods are 

 such valuable trees on the Great 

 Plains, and so variable, it is thought 

 worth while to test this form from 

 Simbirsk Province, Russia, in com- 

 parison with the American forms. It 

 may have more vigor or show other 

 characteristics of value in the north- 

 west.
