 dry feafons fucceeding each other. The infect, 

 however, is now much lefs prevalent ; it feems to 

 dirty, more than otherwife materially to injure 

 the tree, and is now thought lightly of. In the 

 pad feafon, 1811, thefe kifecb have not been fo 

 numerous as in 18105 and they have difappeared 

 fooner, probably owing to the exceffive dampnefs 

 of the fpring and autumn ; circumftances which 

 may tend very much to diminifh their numbers, 

 and hinder their progrefs in fucceeding years. 



THE OAK. 



The Oak is a native both of England and Scot- 

 land. The extenfive and general ufefulnefs of 

 the timber is probably the caufc why it* is alfo 

 to be found planted in a greater variety of foils 

 than moft other trees. It luckily happens that it 

 will grow, and even become timber, on foils of 

 very oppofite natures. It thrives beft, however, 

 in ftrong deep loam, incumbent on gravel or dry 

 rock ; but in all foils in which there is any con- 

 fiderable proportion of loam, it will thrive in a 



greater
