 external air as much as possible. 



Towards the end of winter, the plants should 

 be regularly examined, and cleaned from any 

 filth they may have acquired during that dreary 

 season; such as moss on the surface of the 

 pots, and leaves that have dropped thereon ; 

 also any plants that may have grown into a 

 loose habit should be tied up. The platforms 

 or stages should be clean brushed, whilst the 

 plants are removed, and any worms that may 

 have harboured in the pots dislodged, by turn- 

 ing them upside down, and lifting them care- 

 fully off without breaking the ball of roots ; at 

 the bottom or sides of which they are generally 

 to be found. It is easily known when they are 

 in the pots, by their casts on the surface. In- 

 deed this is a thing; that should be attended to 

 at every season of the year, as they are to be 

 observed more or less at all times, and consi- 

 derably disorganize the ceconoiny of the pot, 

 when suffered to persevere.
