There has been and there is still much dispute as to which of the 
two species yields the more valuable timber. 
n 
deep dry soils, such as the Lower Greensand, where it often occurs 
side by side with Q. sessiliflora and the hybrid. On some such sandy 
soils, Y. Robur is dominant in woods which have a heathy ground 
flora. The natural and semi-natural woods over the various lime- 
stone strata, such as the Carboniferous Limestone and the Oolitic 
limestones, are usually dominated by the common Ash (Fraxinus 
excelsior) ; but frequently, especially in the more lowland of such 
woods, Oaks also occur, usua y Y. Robur, or, rarely, both species. 
ee over the lowlands of the country are 
Q. Robur; but in hilly districts, where stone fences usually take 
the place of hedgerows, specimens of Q. sesstliflora are by no 
means uncommon in the few hedgerows that exist. 
(To be concluded.)
