4 On the Growth of Early and Late Grapes under Glass. 



whole roof without being in the least detrimental to the plants 

 at the back of the house. To prove the superiority of this 

 trellis, some branches were brought from the Vines growing 

 on the rafters, and trained on the trellis ; these ripened their 

 clusters a fortnight sooner than those above, and were ex- 

 ceedingly large and fine. 



The Vines are planted in the earth within the house, for I 

 consider it of the utmost importance to have their roots 

 secure from external exposure ; but I do not by any means 

 desire to have the mould in which they grow heated by the 

 fire; few plants will thrive well if the earth in which their 

 roots are placed is warmed by any other means than that of 

 the atmosphere. 



In pruning these Vines, as little wood should be left to be 

 employed as possible ; I prefer stopping one joint above its 

 cluster, and have no joint without a bunch. Some have 

 difficulty in procuring this, but good practitioners generally 

 have abundance. A single Vinery at this place, fifty-two 

 feet long by fifteen feet wide, ripened in the last season 

 one thousand bunches, besides which, the number of bunches 

 cut off at the time of thinning was considerable ; those which 

 ripened were allowed by some eminent Gardeners to have 

 acquired all the size and flavour that fruits of the same kind 

 were capable of acquiring. 



When the crop is over, and the wood perfectly ripe, the 

 branches should be laid near the ground, and shaded till the 

 recommencement of the forcing. By this practice they will 

 be found to have accumulated excitability. The shade will 

 have some affinity to the gloom of winter, which never fails
