mode, difficulty is found, as vines increase in strength, especially with the 

 stronger-growing varieties, in keeping them confined within their prescribed 

 limits ; and it is more than probable that the severe summer-pruning neces- 

 sary to keep them within reasonable bounds has a tendency to weaken 

 the constitution of the vines. 



For these reasons, the trellis-system of training, with permanent arms, 

 and alternate wood and fruit canes, is much preferred, as affording more 

 space, and being more in accordance with the rambling habits of the vine. 



With a brief description of one of the various modes of trellis-training, 

 I will close the present article ; remarking, however, that the same general 

 principles are applicable to all methods. For trellis, as soon as the vine 

 is strong enough, two canes are grown from near the ground, as nearly 

 equal in size as practicable, tied up during the season, and treated as di- 

 rected for the single cane. In the fall or spring, these canes are shortened 

 back according to their strength, and bent downward right and left, and 

 tied to the lower wire, or bar, of the trellis, with the ends lower than the 

 branch, or fork, on the main stem. This breaks up the tendency of the up- 

 per buds to push most strongly, and equalizes the growth along the whole 

 cane. These arms are intended to be permanent, and may be lengthened 

 as the vine increases in age and strength. The canes springing from these 

 horizontal arms are trained upwards, all superfluous buds and shoots rubbed 

 out and finished off, and those remaining so arranged, that between the fruit- 

 bearing canes of the present season, which would be cut away at the fall- 

 pruning, new shoots are trained up each year for the next season's bearing.
