as tliat tliere may be a coatincj of fresh earth round 

 it, as well as underneath. For ])]ants above the mid- 

 die size, or whose pots exceed eight inches in dia- 

 jnetej-, this coating of new eartli shoidd be about an 

 inch tliick ; tJiat is to say, if tiie old pot be seven, 

 the new one shoukl be nine inches diameter, and so 

 in proportion, for pots of different sizes. 



In all cases of potting, the new mould should be 

 rather in a dry state than otherwise, !it the time ; in 

 which state it divides easily, andean be filled better 

 in about the fibres, than v. hen it is anywise wet. 

 After potting, however, the whole shoidd be settled 

 hy a moderate watering ; and the plants should be 

 shaded from the full sun for a few days, either by 

 an av.'ning, or by mats, placed over the lights 9 or 

 otherwise as may be thought most proper. Plants, 

 however, that ha^'e been most reduced at root in 

 the shifting, require to be more carefully shaded 

 than others; and they may be collected into a cor- 

 ner of the house for a few days, or be placed in a 

 deep frame, for that particular purpose.
