experiments, purposely made, I constantly have found the 

 growth of trees to be most rapid when the roots and leaves 

 are brought nearest to each other, under similar external 

 circumstances; and the horizontal space necessarily occu- 

 pied by the leaves and stems of plants will, in almost all 

 cases, exceed the width of the pots of the form recom- 

 mended. The increased breadth and diminished depth, of 

 the mould, are not, therefore, productive of any loss, or 

 inconvenience: whilst the gardener is enabled to remove 

 his plants from a smaller to a larger pot with great facility, 

 and with much less danger of injury to their roots, than with 

 Pots of the ordinary forms and proportions.
