OF FRUIT AND FOREST TREES, 



trees [Ste Plates II. and V. which fhew. the manner of 

 preparing hollow trees, and alio the growing of the woodj. 



Some months before the publication of the 46 Qbfervations 

 on the Difeafes, &c. in Fruit and Fore ft Trees," I had tried 

 the Compofition in a liquid (late, but did not think myfelf war- 

 ranted to make it public until I. had experienced its effects 

 through the Winter. The fuccefs anfvvered my mod fan- 

 guine expectations; and I have ufed it in that way ever fince. 

 By ufing the Compofition in a liquid ftate, more than three- 

 fourths of the time and labour is faved ; and i find it is not 

 fo liable to be thrown off as the lips grow, as when laid on in 

 the confidence of pi after : it adheres firmly to the naked part 

 of the wound, and yet eafily gives way as the new wood and 

 bark advances. 



The firft time that I tried the Compofition in a liquid form 

 was upon an elm which had been planted about twenty years. 

 It had been very much bruifed by the roller, had feveral cavi- 

 ties in it, and was very much bark-bound befides. Having 

 prepared the wounds, and applied the Compofition with a 

 painter's brufh, I took my knife and fcarifled the tree in four 

 places ; I alio lhaved off, with a draw knife, all the cankery 

 outer bark, and covered the whole tree with the Compofi- 

 tion, fhaking the powder of wood-afhes and burnt bones all 

 Over it. A very heavy rain began in the evening and con- 

 tinued all night ; yet, to my, great fur prize, in the morning, I 

 found that only fome of the powder, which had not had time 

 to dry and incorporate with the Compofition, was waihed off. 

 I now repeated the powder, and, without any thing more 

 being done to the tree, the wounds healed up and the bark 

 was reftored fo completely, that, three years ago, it could 

 hardly be difcerned where the wounds had been. The fcari-
