236 FOE AGE PLANTS AND TEEIE CULTURE 



Crested dogstail is another example of a European grass 

 that fails to thrive under American conditions, probably 

 on account of summer heat. It has often been planted, 

 but has become only very sparingly introduced and has 

 nowhere shown any ability to increase and spread. 



It may prove of some value on the North Pacific Coast- 

 but elsewhere it has shown no promise.
