Because of its exceptional commercial and silvicultural value, 

 Douglas fir bids fair to become the most widely cultivated of the 

 "western conifers. In forest planting it should be remembered that the 

 coast form is superior to the mountain form in almost every respect, 

 and except for ornamental purposes, or for regions where the climate 

 is unfavorable to the growth of the coast form, seed from the Kocky 

 Mountains should never be selected. In Great Britain and in 

 German}^ the coast form has been grown with success; in the north- 

 eastern United States and in alpine situations in Europe the Eocky 

 Mountain form is apparently better able to succeed. In everj^ case 

 great care should be taken, in selecting seed, to choose that from 

 rapid-growing, straight, symmetrical trees.
