I Have more than once mentioned in the Transactions of 

 this Society the importance of giving to fruit trees, from 

 which a crop of fruit is required very early in the season, a 

 high degree of excitability, or the power to vegetate very 

 strongly in moderately low temperature, at the period when 

 they are first subjected to artificial heat :* and I have pointed 

 out the advantages of retaining all trees, which are intended 

 to afford such very early crops, in pots.f In the present 

 season, I have endeavoured to ascertain within how short a 

 period, in the ordinary temperature of my Pine stove, plants 

 of the Chasselas and Verdelho Vine could be made to yield 

 mature fruit. 



The subjects of this experiment had produced a crop of 

 fruit previously to midsummer, 1820, and in the following 

 month of July, they had been taken from the stove, after 

 having been for some time sparingly supplied with water, 

 and placed under a north wall ; in which situation they re-
