80 THE GRAPE. 



summer, and that which is given in the greatest ex- 

 tremes of forcing, will be subjected to as much if not more 

 of that element than is to be found in the very hottest 

 parts of the world, in which regions our present subject 

 does not thrive ; but in the most extreme cases, it is better 

 to commence anew when nature is so far exhausted as to 

 be no further remunerative, and as in establishments where 

 this is required, there are always several houses at work, 

 there is no difficulty in having the worn-out lot replaced 

 by another planting. 



Where grapes are required so early, as above mentioned, 

 it is necessary that the outside borders should have a share 

 of attention, and we here take the opportunity of offering 

 a few general remarks on this head. 



If we refer to those localities or climates where vegeta- 

 tion prospers best, and to the most fruitful regions, we 

 shall find that there is no great disparity in the average 

 degree of heat between the atmosphere and the ground 

 in which the roots of plants exist ; consequently, there is 

 a reciprocity, and an equal action, or equal quiescence 

 over all parts. We know likewise from experience, that 

 if the head of any plant were exposed to summer heat, 

 and the roots in the cold of an ice house, prosperity could 

 not long continue ; in such a case, if it were positively 

 seen, we should know the evil results that would follow, 

 and alter the circumstances accordingly, yet strange to 

 say, there are some men at the present day, strongly at- 

 tached to planting the grape vine outside of the house, 

 and still stranger, the same persons are more particularly 

 so when forcing is intended ; such men will argue that in 

 this position, the roots more readily progress through the 

 outside borders, and that it is indispensably necessary, as 

 they have seen fine grapes grown in this way. Such logic 

 is, however, contrary to all true physiological reasoning,
