jQP THE BARK. 29 



Kensington gardens, the history of whose ex- 

 periments is before the pul>hc. Under his 

 management many timber trees, become en- 

 tirely hollow, were filled with new wood, and 

 made to produce fresh and vigorous branches; 

 and pear-trees planted in the time of King 

 William, and become so decayed and knotty 

 as to bear no fruit worth gathering, were by 

 gradual paring away of the old wood and 

 bark, and the application of a composition 

 judiciously contrived to stick close and keep 

 out air and wet, restored to such health and 

 strength as to cover the garden walls with 

 new branches bearing a profusion of fine fruit. 

 These experiments have passed under my 

 own actual observation, and I am happy to 

 bear testimony to the merits of a real lover of 

 useful science, and one of the most honest 

 and disinterested men I evep knew.
