THE EARLY GRAPERY OR FORCING HOUSE. 79 
forcing of the same rtock weakens, and eventually wears 
aut the plant, in consequence of which it is best to alter- 
nate ; to a certain extent we may admit, that there is some 
truth in this, but not so much as some would seem ta 
think ; if the borders were to be kept warm, and the roots 
attended to with the same care as the tops, there pkey 
not be so many examples of early imbecility to complain 
of. True, all may be done that ingenuity can invent, and 
yet the exact growing temperature of summer will not 
_be obtained—artificial heat is not so stimulating as that of 
the sun, but in our cloudless clime, even in the winter 
time, there is much bright and clear weather, which con- 
siderably assists our action, and if not quite so favorable 
as we could wish, it is sufficiently so to enable us, with 
management a proper conveniences, to so far stic- 
ceed that a house of vines will admit of being uninter- 
ruptedly forced for many years in succession, and with 
far more certainty than the exploded notion of resting. 
It is more reasonable, and much more consistent with 
— that the same periodical action should be allowed 
to go on, provided it is not opposed to the peculiar consti- 
tution of any particular plant, and in the case before us, 
there does not seem to be anything unnatural, unless the 
allowing of a greater length of time for the full concentra- 
_ tion of the juices can ese uniaaee and it is well known 
that the finest grapes, and most prosperous vines, are to 
be found in those countries which have longer and steadier 
summers than our own. So that, if all is well done that 
ought to be done during the earlier stages of development, 
the plants have all the remainder of the summer to mature
