 the bark bed being renewed, a moderately good 

 fire heat will greatly assist the plants in taking 

 fresh root, and which should be kept up until 

 the heat of the bed rises to the top,

If the heat of the bark-bed should have 

 greatly declined (particularly in the depth of 

 winter) before it is the usual time, or convenient 

 for the regular renewal, a quantity of fresh bark 

 may be added at top, and forked up with the

 towards spring, but in the fruiting department; 

 should the heat decline later in the season, or 

 during the general fruiting, it may be renewed 

 without disturbing the fruiting pines ; for when 

 they are far advanced, the removal of the pots is
