22. Quercus macrocarpa. 



This, which, next to the Quercus alba, is the 

 most important American oak, shows also no dif- 

 ference in its sylvicultural qualities. In Germany 

 it is of as little importance as the alba. 



23. Quercus palustris. 



This oak is more modest in its demands upon 

 the soil than indigenous oaks, grows more rapidly 

 than the latter, but is inferior, as already men- 

 tioned, in the quality of its timber. The treat- 

 ment is the same as that of European oaks, but 

 whether it possesses the same advantages as the 

 red oak has yet to be proved. 



24. Quercus rubra. 



Thrives wherever oaks are to be found, is 

 very quick in growth, easily transplanted, and 

 can be utilised on indifferent soils (pine soils 

 of No. 3 quality). Its slight shade-bearing 

 quality makes it suitable for underplanting pines, 

 and its rapidity of growth allows it to be em- 

 ployed later on for filling up any gaps in all 

 broad-leaved, also pine, cypress, and thuja 

 plantations, and it is equally suitable in copse, 

 where, however, its reproductive capacity is 

 smaller than in the case of the white oak.
