 natural landscape forms. We should further no- 

 tice especially that each of these forms has its own

 mountains without thinking of the spirit of the

 Wilhelm Miller has recently published a notable 

 treatise on "The Prairie Spirit in Landscape Gar- 

 dening," which deals, as a matter of course, with 

 both the physical prairie and the spirit of the plains. 

 While topography, the main element of the nat-

 discussion of these geologic and geographic data, 

 but merely to make it clear that the natural land- 

 scape does present perfectly definite and recog- 

 nizable forms determined by perfectly simple and 

 well-known forces. The question of vegetation, 

 however, and its relation to landscape forms de-
