Abies Concolor and Abies Grandis. — Both are remarkable for their 

 rapid growth in moist soils, which are somewhat fertile. 



Brief mention is also made in the following expressions to: (1) 

 Libra cedrus Decurrens, yielding a wood for special purposes; (2) 

 Chamaccyparis Nootkatensis, similar to Chamaecyparis Lazvsoniana ; 

 (3) Taxodium Distichum (Chauve cypress), which planted along water 

 courses assumes large dimensions and furnishes a wood of special 

 character; (4) Tsuga Mertensiana (Tsuga de Calif ornie), a tree of 

 rapid growth, much more interesting from a forestry viewpoint than 

 its relative Tsuga canadensis. (Apparently none of the above species 

 have been. planted to any extent in France.) 



HARDWOODS 



Robinia Pseudacacia; Robinier faux acacia (Robinia false acacia). — 

 An American tree which has been introduced into France on the 

 plains, hillsides, and the bases of the mountains. It prefers soils light 

 and somewhat moist. It is hardy and grows more or less on all kinds 

 of soils. It is intolerant, seeds abundantly in the autumn. Its seeds 

 are easy to keep. They germinate in the springtime in from ten to 

 fifteen days. It sprouts and suckers abundantly. It can be grown in 

 simple coppice or coppice under standards. When planted upon a good 

 soil it becomes a very fine tree and forms excellent open plantations. 

 Its branches are easily broken by the wind. It is valuable for fixing 

 eroding soils on slopes, because its root system is solid and wide 

 reaching, and because of the facility with which it sprouts and suckers. 



Its wood is yellowish, heavy, hard, elastic, and durable, being excel- 

 lent for wagon spokes, rungs of ladders, parquetry, turnery, etc. It 

 burns well and yields fair charcoal. Its leaves can be used for forage. 



(One thing which gives this species a value in Europe which it 

 does not posses with us is the fact that it escapes the ravages of the 

 locust borer which makes its successful cultivation in America almost 

 impossible. The black locust is probably the most common American 

 tree species now growing in Europe. It is perhaps even more common 

 in Germany than in France. The writer's general observations lead 

 him to believe that the species is somewhat more tolerant in Europe 

 than at home as would be indicated by the statement that it can be 

 grown as coppice under standards.) 



Quercus Rubra; Chene rouge d'Amerique (American red oak). — A 

 large tree with fairly rapid growth, which has shown itself to be very 

 hardy with us, is strongly resistant to frost. It does well on the plains 

 and in valleys. Does not seem to be exacting in its soil requirements,
