OP FRUIT AND FOREST TREES. 407 



been benefited by the application of this Com- 

 position ; and we desired him to shew us what • 

 specimens he could of such trees in all the stages 

 of their amendment and recovery. In conse- 

 quence of this requisition, we were conducted 

 to many forest-trees of different kinds, (viz. Elms, 

 Limes, and Horse-Chesnuts) in which holes and 

 wounds, in some instances several feet in length, 

 and of a considerable width and depth, had been 

 completely filled up with sound wood, so as the ' 

 outline of the wound remained barely discernible 

 in the bark. We examined many others in an 

 evident state of progress towards a similar cure; 

 and we could not discover any one of the experi- 

 ments that fell under our observation, of which 

 we had the least reason to doubt the success. 

 We examined also several experiments upon 

 trees, which, standing near each other, had been cut 

 down, and to the stems of which the Composi- 

 tion had been applied, while the others had been 

 left to nature : the uniform result of these ex- 

 periments appeared, that those stems to which 

 the Composition had been applied had shot up 

 into healthy vigorous trees, in far less time than 

 we should have conceived possible : while those 

 left to unassisted nature had only produced ir- 

 regular, unhealthy shoots, and were apparently in 

 a state of decay. Several experiments had also 

 been made on decayed and hollow stumps (where 

 little or nothing but bark remained) of Elms of 

 very considerable size and age : from these stumps,
