wood, I had applied the Composition about sixteen 

 years ago, was cut down last year on purpose to 

 examine the progress it had made in the interior 

 part, and was found entirely filled up with new 

 sound wood, whicli 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 posses- 

 sion, 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 Palace-green, which was headed about twenty 

 feet from the ground, has produced a shoot forty- 

 six feet high, and five feet nine inches in circum- 

 ference. 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 two feet in circumference. These are 

 now fine thriving trees, and the cicatrices hardly 

 discernible. 



A Horse-Chesnut headed down has produced, 

 from its hollow stump, four fine shoots, one of 

 which is cut down ; the other three are upwards 

 of thirty feet high, and one of them is twenty-six
