Thirdly, They alledge, and this is but too prevalent an 
opinion, that grapes produced in Pine-ftoves are feldom fo well 
flavoured as grapes from a Vinery. 
To the firfl: of thefe objedtions I here reply, by aflerting that 
the Vine will bear the degree of heat proper for Pines, and 
that this is proved by daily experience. There is a Vine now 
(1789) growing in the Pinery at Welbeck, which has con- 
flantly produced good crops of grapes for more than twenty 
years paft. Its roots are entirely within the houfe, and make 
annual progrefs in the Pine-pits, among the leaves of trees, 
which are ufed here inftead of tan } and pleafe to confider, that 
in this mode of proceeding, the (ituations of the Pine and Vine 
are extremely different. 
The Pine is fltuated in the lower part of the houfe, "but 
the fhoots of the Vine are trained immediately under the 
roof, and, confequently, are greatly affedted by the external 
air, efpecially when fuch air is admitted into the houfe. Be- 
fides, let me add, that the Pines, being plunged in the tan- 
bed, receive a conftant warmth from thence, and their roots 
are nouriflied by its genial heat. But the whole fyflem of the 
fibres in the roots of the Vines being in the open ground on 
the outfide of the houfe, .they are at all times expofed to the 
weather, which mufl; neceffarily have a wonderful effedl upon 
the whole plant at all feafons of the year.
