 the bed, and be cautious not to plunge the pots 

 while it is too violent; and in case the heat 

 should increase to too great a degree, it will be 

 necessary to draw up the pots half-way, or raise 

 them sufficiently to prevent the plants from 

 burning. 



If the plants are raised in a bark-bed pit, or 

 the principal pinery, or succession house, they 

 may there remain ; but it will be necessary occa- 

 sionally, when the heat declines, to fork up the 

 tan, or when the heat is greatly reduced, a 

 small quantity of new bark may be added, and 

 mixed with the old, and then plunge the pots 

 again immediately. If the heat in the dung hot 

 bed should decline before convenient to remove 

 the plants, it can be revived by linings of fresh 

 hot dung along the sides, but in six weeks or 

 two months they will be in a fit state to remove 

 in the same pots to the succession house or 

 bark-bed pits, but where there is not this ac- 

 commodation, they may be removed to the bark-
