against the top like the letter T, as shown in Fig. 271 

 The wires in this way are stretched along the ends of this 

 horizontal piece, with the third midway between them 

 and 10 or 12 inches lower. In this system a single main 

 trunk is grown to the middle or lower wire, and one or 

 two canes (depending upon age and vigor) are left after 

 pruning to run each way upon this middle wire and se- 

 curely tied. The remaining or outer wires are used only 

 to support the growing shoots, which, with but little 

 attention, grow out over them as seen in the illustration. 

 As their length and weight increase they gradual)}' 

 droop toward the ground, having in the meantime secured

 easily understood from Fig. 272. 



Pruning vines in this system is similar to that in the

 and the canes are attached to only the middle or lowest 

 wire. Thus a strong and vigorous mature vine should 

 have two or more canes left in each direction after prun-
