416 OBSERVATIONS ON THE DISEASES, &C. 



the Winter. The success answered my most san- 

 guine expectations ; and I have used it in that way 

 ever since. By using the Composition in a liquid 

 state, more than three-fourths of the time and 

 labour is saved ; and I find it is not so liable to be

 shaved ofij with a draw-knife, all the cankery

 without any thing more being done to the tree, 

 the wounds healed up and the bark was restored 

 so completely, that, three years ago, it could 

 hardly be discerned where the wounds had been*
