818 JOURXAL OF FORESTRY 



US. where it grows by preference in humid valleys. It demands deep 

 fresh soils, of some fertility and a humid atmosphere. It prefers 

 siliceous soils and grows poorly on limestones and heavy clays. It seeds 

 regularly and abundantly, can be grown in full stands and may be 

 introduced for trial. Having a fairly rapid growth, it presents the 

 same interest as the preceding. 



(This tree is well known in Europe as an ornamental tree, but it has 

 never been used in the United States for forest planting, so little 

 can be added to the above.) 



Psciidotsuga Doiiglassi; Faux tstiga de Douglas (Douglas false hem- 

 lock). — This is a very fine American tree which has shown itself very 

 hardy with us. It prefers deep siliceous soils, somewhat fresh, but it 

 is content with relatively dry sands and a mediocre fertility. It always 

 does badly on too dry a soil and will not grow on limestone soils, 

 further it requires a humid atmosphere. This tree planted on plains 

 and in fertile valleys has a rapid growth, and seeds regularly. The 

 voung trees require shade for their first three or four years. The tree 

 can be grown in closed stands and may be introduced into the forest 

 as an experiment. 



(This tree has been successfully introduced into England as well as 

 France. It was introduced into the former country about 1820 both 

 as a timber producer and an ornamental. In fact it was from the 

 English that its value for the latter purpose was first realized for the 

 eastern United States. 



Owing to climatic conditions probably seed from the Pacific Coast 

 would give better results in France than that from the Rocky Moun- 

 tains.) 



Picea Piingcns {P. parryana) ; Epicca piquant (Pungent Spruce). — 

 This American tree has shown itself very hardy in France, and seems 

 to be able to accommodate itself to moist even peat-like soils, some- 

 times also to dry soils. It is a good tree with a rapid growth, which 

 can be planted from the lowlands to the upper limit of vegetation on 

 all sorts of exposures. A species interesting to try out for forestation 

 of moist soils and old pastures. Its very sharp and pungent needles 

 defend it againt grazing animals. 



(This species was introduced into England about 1877 and later into 

 Germany where it has given good results for forest planting. Because 

 of its bright blue needles it is also grown to a considerable extent in 

 Europe as an ornamental.) 



Picea SitcJietisis; Epicea de Menaes (Menzies' spruce). — An Amer- 

 ican tree apparently hardy in France. It prefers fresh siliceous soils.
