Success of several Experiments^ since the Publication of Oh* 

 sermtions on the Diseases, Defects, Sffc," 



Since I published my " Observations on the Diseases, De- 

 fects, and Injuries in Fruit and Forest- Trees," I have been as- 

 siduous in making experiments for the sake of improvements 

 A great many hollow trees that had, when I took them in hand, 

 little more than the bark remaining sound, have within these 

 few years been entirely filled up? Others, that were headed 

 down within a few feet of the ground, have their stumps now 

 completely covered by the leading shoot, forming handsome 

 trees ; and the places where they were headed are only discern- 

 ed by a faint cicatrix. Of a great many, I shall only parti- 

 cularize a few instances. 



A lime^-tree, about eighteen inches in diameter, whose 

 trunk was decayed and hollow from top to bottom, to which, 

 after cutting out the decayed wood, I had applied the compo- 

 sition about sixteen years ago, was cut down last year on pur- 

 pose to examine the progress it had made in the interior part, 

 and Was found entirely filled up with new sound wood, which 

 had completely incorporated with what little old wood remained 

 when I first took it in hand. The body of this tree I had cut 

 in short lengths, which 1 have now in my possession, to shew 

 to any gentleman who wishes to be convinced of the fact. An 

 old elm whose inside was totally decayed, and out of which, at 

 different times, were taken two large cart loads of rotten wood, 

 has made shoots upwards of twenty feet high in the course 

 of six years. Another elm, on the IPalace Green, which was 

 headed about twenty feet from the ground, has produced a 

 shoot forty-six feet high, and five feet nine inches in circumfe- 

 rence. A lime, cut down near the ground, has now a shoot 

 twenty feet high which entirely covers the stump, forming a 

 fine tree twenty-one inches in circumference. A Sycamore 

 treated in the same manner is now thirty feet high, and twenty- 

 six inches in circumference. Another is thirty feet high, and
