THE GRAPE VINE. 



GREENHOUSE. 



Under this head may be considered not only the 

 modes of cultivating the grape vine in the same house 

 with flowering plants, hut also its cultivation in a 

 vinery by itself, with a similar employment of heat 

 only sufficient to exclude frost and other low tempe- 

 ratures at certain periods of the vine's growth. These 

 periods are chiefly in early spring, when the occur- 

 rence of night frosts and easterly winds endanger the 

 opening buds — and late in autumn, when cold damp 

 weather may render a little artificial heat desirable, 

 either to promote the ripening of the wood, or pre- 

 serve from mouldiness the ripened fruit. 



With regard to training, pruning, and thinning, in 

 the greenhouse, they are fundamentally the same as 

 in the stove (see next section), but with especial care 

 on these points : 1 . . To train the vines to the rafters 

 or otherwise, so that they shall not overshadow the 

 interior before the end of May. 2. To empty the 

 greenhouse of all greenhouse plants after that period,
