Altogether it appears that a plantation of this kind with all 

 the repair planting, etc., that may be needed, can be accomplished 

 for not to exceed $32, a saving of $18.

Walther points out the difficulty of securing 

 Douglas seeds from definite localities and hence the 



Fir very variable appearance and behavior, espe- 



in cially later or earlier budding, of Douglas 



Germany. Fir, which can be specially noticed in nur- 



sery beds. The original importations which 

 began in 1827 were undoubtedly of the green variety from Oregon 

 and Washington with horizontal to pendulous branch habit and 

 rapid growth. The gray to blue variety of slower growth from 

 the Rockies came in after the eighties. 



For favorable localities, like Hesse, the green variety is adapted 

 according to 30 years' experience ; for frost situations only the 

 blue or gray variety suits. 



This was specially observed in October, 1908, after a wet, cool 

 summer, with extraordinarily small rainfall in October, followed 

 by early frosts. In the midst of groups of the Douglas Fir single 

 plants, even well protected ones, froze back for one to three an- 

 nual shoots, especially on east exposures, the explanation being 

 that these were of the coast variety. The older, 20-40-year trees, 

 and protected ones did not suffer, even in exposed situations and 

 even though they were of the green variety. This is explained by 

 the probably more northern derivation of the plant material. 

 Especially on dry soils is frost danger frequent. 



The variety caesia (the name given to the gray-green variety) 

 seems to combine the rapid growth of the green and the frost re- 

 sistance of the blue variety. The Douglas Fir seems to resemble 

 the German Fir as regards its gratefulness for shade when young, 

 the light shade of Scotch Pine being especially favorable. Several 

 illustrations accompany the article, showing excellent stands of 

 this Fir.
