When it is convenient, it is a desirable plan, 

 before removing the plants to where they are to 

 remain, to let the bark beds settle a little and

 the heat , and when at a proper temperature, 

 with the assistance of a short, narrow, one-

 pots as before directed ; but be careful should

 the heat is too strong, they may at first be
