300 OBSERVATIONS ON THE DISEASES, &c. 



ton, where the falutary effe&s of the Compofition are evident 

 to every attentive obferver. 



The firft trials of its efficacy were made on fome very large 

 and antient elms, many of which were in a moft decayed ftate, 

 having all their upper parts broken, by high winds, from 

 their trunks, which were withal fo hollow and decayed, that 

 a fmall portion alone of the bark remained alive and found. 

 Ofi.th.efe trees I cut away at firft a part only of the rotten 

 {luff from the hollow of the tree, and then applied the plafter 

 to the place where the operation had been performed, by way 

 of an internal coat of the Compofition. In a fhort time, 

 however, the efforts of nature, with a renovated flow of the 

 juices, were clearly difcernible in their formation of new 

 wood, uniting with, and fwelling, as it were, from the old, 

 till it became a ftrong fupport to that part of the tree where 

 the Compofition had been applied. I then cut away more of 

 the rotten wood from the infide, applying the plafter in the 

 fame manner, with the fame good effects, and continued to 

 ufe the knife in proportion to the acquifition of new wood ; 

 fo that, from the tops of thefe decayed and naked trunks, 

 ftems have actually grown of above thirty feet in height, in 

 the courfe of fix or feven years from the firft application of 

 the Compofition ; an incontrovertible proof of its good effects, 

 in reftoring decayed vegetation. 



Many other elm trees, which had received hurts- from 

 bruifes and other caufes, and where difeafe and decay were* 

 already evident, after cutting away all the infected part, and 

 duly applying the plafter, were fo completely healed, that the 

 outline of the wound is fearcely difcernible on the bark, and 

 the new wood is as perfectly united to the old, as if it had 

 been originally formed with the tree.
