vegetate at all in the winter without a very high degree of 

 heat, is not as well calculated for very early forcing as one 

 in which the powers of life are so excitable that it is pre- 

 pared to vegetate strongly in the temperature of the open 

 air in September, and in which the power to vegetate in a 

 low temperature will continue to accumulate progressively 

 till spring : but it will probably be objected that as large a 

 crop cannot be obtained from Vines of which the roots are 

 confined in pots, as from others. This objection, however, 

 will, I believe, prove to be wholly unfounded, whenever a 

 very early crop is wanted ; for Vines and other fruit trees 

 (as I have observed in former papers) when abundantly 

 supplied with water, and manure in a liquid state, require 

 but a very small quantity of mould. A pot containing two 

 cubic feet of very rich mould, with proper subsequent at- 

 tention, is fully adequate to nourish a Vine which, after 

 being pruned in autumn, occupies twenty square feet of the 

 roof of a hot-house ; and I have constantly found that Vines, 

 in such pots, being abundantly supplied with food and 

 water, have produced more vigorous wood, when forced very 

 early, than others of the same varieties, whose roots were 

 permitted to extend beyond the limits of the house.
