PREFACE. 
xui 
That the fecond objedlon is of force, where the Vines in a 
Hot-houfe are under an injudicious management, muft be 
admitted ; but when their ihoots are trained with propriety, 
and according to the method herein prefcribed, the Pines will 
rather be benefited than injured, by the kindly fhade the Vine 
leaves will afford. 
And as to the lafi; objedlion, grapes, well perfected in Hot- 
houfes, are generally very rich ; but it mufi; be confeffed that 
their fkins are very often impregnated with a difagreeable 
flavour: But Ffhall venture to affirm, that the caufe of this 
defed: moff: generally proceeds, either from the languiffiing 
flate of the Vine, the effed of infeds, or elfe from fumiga- 
tions, or fome fimilar pradice, made ufe of to deftroy the va- 
rious infeds that infefl; Hot-houfes ; and, therefore, I infiff:, 
firff, that a plentiful admiflion of free air in fummer is as ne- 
ceffary for the Pine as the Vine. See fedion on air, &c. p. 59, 
in my Treatife on the Culture of the Pine, &c. 
And fecondly, that when air is properly and plentifully ad- 
mitted into the Hot-houfe, and every other part of the ma- 
nagement is conduded with propriety, grapes produced in 
Pine-ffoves commonly prove well flavoured, and in a high 
flate of perfediom 
The advantages to be gained by the new methods of propa- 
gating the Vine by feed, and by engrafting, appear very con- 
fpicuous
