We quite agree with Dr. Horner in thinking, that 

 the disease is not contagious, hut that it is simply the 

 result of had cultivation ; what produces it in one 

 plant, produces it in all. Want of drainage, old tap 

 roots, damp, and confinement, are, severally and col- 

 lectively, the principal causes of rot in the Auricula. 

 To prevent it, repot annually, taking care to shorten 

 the tap-root (a part peculiarly liahle to canker and 

 disease) to within an inch or an inch-and-a-half of the 

 insertion of the leaves. Secondly, fill the pot nearly 

 one-third with hroken crocks. Thirdly, let the pots, 

 in summer and autumn, stand in a shady, airy part of 

 the garden, and elevated two feet above the ground. 

 And, fourthly, place them, in winter and spring, in 

 such a frame as is before represented. {Gard. Chron. 

 1843, 860.) 



There are two other points deserving particular at- 

 tention, to secure safety from the disease. Of these, 

 the first is to have plenty of rubbly pieces of charcoal 

 among the drainage, for these are grateful to the roots, 

 at the same time that they are antiseptic ; and the 

 second is, that great care ought to be taken not to 

 rend the main root of the mother plant in removing 

 the offsets, for this often induces decay ; less injury 

 will arise from a clean cut with a sharp knife than 

 from a forcible separation of the offsets by the fingers.
