 put into the proper mould specified for them, in the 

 Section on Soils for forced Plants. Let them be re-

 medium. 



If the mercury stand at 65, or between that

It will be proper at this time (about the first of 

 the month) to renew the heat in the bark bed, 

 which will now have considerably decreased, in or-

 tom may keep pace with the superficial heat. Let 

 new bark, therefore, to the extent of about a tenth, 

 or an eighth-part, be added ; keeping it well down, 

 however, that the pots may be entirely plunged in 

 the old bark. 



Trim the plants of decayed leaves, or those bruised 

 at the 'points ; reducing an inch or two of the 

 earth from off the surface, and adding some fresh
