different, though it is generally alleged that plants of Q. sessiliflora grow 

 faster, and they certainly have a more robust appearance, than those of Q* 

 pedunculata, when of six or eight years' growth; for which reason Mr. Bree 

 considers it the best species for copse wood. (See (lard. Mag., vol. xii. 

 p. .,'ii.) \\ illdcnou observes, also, that Q. pedunculata is the tenderer 

 of the two when young, which may result from its coining earlier into leaf. 

 Tin- growth of both species, ill about 10 years from the acorn, in good soil, in 

 the climate of London, may be stated as from 15 ft. to 18 ft., or even more, if 

 extra preparation were given to the soil. Both will attain the height of 50 ft. 



in 30 years, which ma) be considered the average height of the species in 

 ordinary oil in England ; but, in deep loamy soils, both attain the height of 

 loo ft. and upwards. The stem of the oak, Marshall observes, is naturally
