When we contemplate the manner of the produdion of the 

 I wood of trees from the induration of the fap-wood, and the 

 increafe of the fap-wood from the bark, which was previoufly

And in this Country, when the internal wood is gradually detach- 



ed from the alburnum, as it decays, as in fome old hollow oaks and 

 willows, fo that it does not deftroy the tree by the putrid matter 

 beino- abforbed, there fcems to be no termination of the growth of 

 the external remains of the tree, till the wind blows it down from its 

 want of folid wood to fupport it. Of this kind of hollow tree a re- 

 markable inftance remains in Welbeck Park in Nottino;ham(hire, 



through the middle of which a coach is faid to have been driven. There 



is another oak of uncommon dimenfions in the foreft of Needwood,
