OP THE BARK. 



Kensington gardens, the history of whose ex- 

 periments is before the public. Under his 

 management many timber trees, become 

 entirely hollow, were filled with new wood, 

 and made to produce fresh and vigorous 

 branches ; and pear-trees planted in the time 

 of Kino; AVilliam, 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 composi- 

 tion 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 ever knew.
