physiologist, " believe that an old dying tree can be 

 restored to youth and vigour, merely by being plas- 

 tered with lime, cow-dung, and wood ashes, and that 

 a piece of such tree may by such means be made im- 

 mortal, I think it would be a good speculation for 

 some enterprising genius, in imitation of the quack 

 doctors of the sixteenth century, to bring forward a 

 nostrum to restore and perpetuate youth in the human 

 subject. Should such a projector join Mr. Forsyth, 

 and the one undertake the animal, and the other the 

 vegetable world, under Dr. Anderson's patronage, I 

 will venture to predict that the success of each in the 

 cures they perform will be equal." 



It has been very ingeniously suggested, that, if a 

 destruction of the bark by external violence, and, con- 

 sequently, likely to terminate in canker, has occurred, 

 it would be a good plan to insert, as in budding, a 

 piece of living bark, exactly corresponding to the ex- 

 cision, from a less valuable tree. 



In conclusion, we would enforce upon the orchard- 

 ist's attention the importance of obtaining his grafts or 

 buds from trees not affected by the disease, because, 

 apparently, it is hereditary ; and, although after-cul- 

 tivation may eradicate the malady, it is always far 

 better to avoid the infection than to have to employ a 

 remedy. {Johnson 9 s Principles of Gardening, 295.)
