in Bavaria there are only a few single specimens. 

 Dr. Fernow, 1 of the United States, says that this 

 birch is only a small tree which scarcely deserves 

 planting, whereas 



5. Betiila lutea, Michx., Yellow Birch, 



is the tree which yields the valuable wood of the 

 yellow to reddish colour. Experiments with this 

 have not been made in Europe. 



6. Betula papyri/era, Marsh, Canoe Birch, 



White Birch. 



Only in Austria, according to Cieslar, 2 have 

 experiments with this birch been made in order 

 to prove the usefulness of this species in high 

 mountains. 



7. Carya alba, Nutt, White Hickory, Shellbark 



Hickory. 



With this, the most important of the Carya 

 species, 16770 acres had been planted, according 

 to Schwappach 3 (/..), in 1884, and in 1901 

 only ior67 acres left; an unsatisfactory result, 

 taking into account the new plantations, which 

 were doubtless made during this period.
