324 OBSERVATIONS ON THE DISEASES, &c. 



on with a painter's brufh. The powder of wood-afh.es and 

 burnt bones is to be applied as before directed, patting it 

 down with the hand. 



When trees are become hollow, you mull fcoop out all the 

 rotten, loofe, and dead parts of the trunk till you come to the 

 folid wood, leaving the fnrface fmooth ; then cover the hol- 

 low, and every part where the canker has been cut out, or 

 branches lopped off, with the Compofition ; and, as the 

 edges grow, take care not to let the new w r ood come in con- 

 tact with the dead, part of which it may be fometimes ne- 

 ceffary to leave ; but cut out the old dead wood as the new 

 advances, keeping a hollow between them, to allow the new 

 wood room to extend itfelf, and thereby fill up the cavity, 

 which it will do in time, fo as to make as it were a new tree. 

 If the cavity be large, you may cut away as much at one opera- 

 tion as will be fufficient for three years. But in this you are 

 to be guided by the fize of the wound, and other circum- 

 fiances. When the new wood* advancing from both fides of the 

 wound, has almoft met, cut off the bark from both the edges, 

 that the folid wood may join, which, if properly managed* 

 it will do, leaving only a flight feam in the bark. If the tree 

 be very much decayed, do not cut away all the dead wood at 

 once, which would weaken the tree too much, if a ftandard,, 

 and endanger its being blown down by the wind. It will* 

 therefore, be neceffary to leave part of the dead wood, at 

 firft, to ftrengthen the tree, and to cut it out by degrees as 

 the new wood is formed. If there be any canker, or gum 

 oozing, the infected parts muft be pared off, or cut out with 

 a proper inftrument. When the ft em is very much decayed,, 

 and hollow, it will be neceffary to open the ground and ex- 

 amine the roots ; then proceed as directed for hollow Peach- 

 trees ;
