OF THE VINE.

to this plan ever since, and it has enabled me to 

 produce finer grapes than I have ever seen or heard 

 of being grown on open walls in this country. And 

 so prolific does every vine become, from the hard 

 pruning which an adherence to this scale compels, 

 that I have frequently to cut off at the proper period 

 in the summer, as much as one half, and sometimes 

 even three fourths of the fruit which many of the 

 vines show, in order to reduce it to its proper 

 quantity. 



Vines thus pruned, with the bearing- wood annually 

 adjusted to their respective powers of maturation, 

 being kept within a small compass on the surface of 

 the wall, are easily managed throughout the summer. 

 They never fail to produce an abundant supply of the 

 finest description of bearing-shoots within a reasona- 

 ble distance of their stems, and always bring their 

 fruit to the highest degree of perfection which the 

 climate will permit, with a certainty which has never 

 yet attended the production of grapes on open walls 

 in this country. 



Scale of the greatest quantity of grapes, which any vine can perfectly 

 mature, in proportion to the circumference of its stem, measured just

It will be seen, that if 2\ inches be deducted from 

 the circumference of the stem of any vine, the capa- 

 bility of it will be equal to the maturation of ten 

 pounds of grapes for every remaining inch of girt. 

 The proportionate quantity for fractional parts of an 

 inch may be easily calculated. 



The circumference of the largest stem in this scale 

 is ten inches, beyond which size I have had no op-
