94 ON THE TRAINING OF VINES. 



Fig. 4. 



vines may be trained on a high wall, allowing to each 

 a certain parallel space in a horizontal direction, and 

 running the stems to such heights as the arms of each 

 vine are to be trained. And when the height of a 

 wall exceeds eight or nine feet, this method may be 

 adopted with great advantage ; for, by planting the 

 vines sufficiently close to each other, the surface of 

 the wall may, in a very few years, be completely cov- 

 ered with fruit and bearing-wood. 



But although the mode of training represented by 

 figures 3 and 4, may be considered the most eligible 

 in all cases where the surface of a wall receives the 

 solar rays in an equal degree, yet, as it will frequently 

 happen that some parts of the surface of a wall, are, 

 from local causes, either wholly or partially in the 

 shade, while the other parts receive the full force of the 

 sun's rays, it is necessary to observe, that in such cases 

 the figures above-mentioned cannot be adhered to with- 

 out inconvenience ; the mode of training, therefore, 

 must, in those instances, be governed entirely by local 

 circumstances. 



It must be remarked, in reference to the winter 

 training of the shoots, that when they are trained in a 

 horizontal manner, there is not that necessity for ser- 

 pentining them, as when they are trained vertically ; 

 unless the vegetation of the vine be so extremely vig-
