is the same either way. Eight inches lower than the two 

 side wires there is a third wire fastened to the posts. 

 This brings the three wires into a very broad V shape. 

 There are no other wires on the trellis. 



"The system of pruning, which forms a necessary part 

 of the scheme, provides that one or two stems be brought 

 up to the lower or middle wire, and that from these stems 

 canes 'shall be run each way along this wire. From these 

 canes the bearing shoots come at right angles, and natur- 

 ally fall out over the top wires. Renewals are most easily 

 made by spurring at the point on the lower wire where 

 the canes are given off from the main stem, though it is 

 often a very easy matter to renew quite from the ground. 



"This system has been in use at the Oklahoma Experi- 

 ment Station from the first, though that is not very long, 

 and has given abundant satisfaction in most particulars. 

 At the first glance, those who are familiar with our severe 

 winds, but not with the working of this trellis, are much 

 inclined to fear great damage from the whipping of the 

 shoots, but, as a matter of fact, this serious difficulty is 

 nearly overcome by the Munson trellis. It is one of the 

 most vexing problems in the ordinary horizontal -arm train- 

 ing, but the increased height of the trellis does not in- 

 crease the trouble. On the other hand, the peculiar position 

 occupied by the growing wood gives it almost complete im- 

 munity. The green shoot is supported in two places near 

 its base, while most of its length hangs free. Though it 

 may swing in the wind, there is nothing against which it 

 may strike, and so the damage is avoided. 



"Mr. Munson sets forth his ideas of the advantages of 

 this system in Professor Bailey's r American Grape Train- 

 ing/ page 81. However, in our experience here, his sum- 

 mary is unsatisfactory. Some of the advantages which he 

 claims do not seem to be peculiar to this system of train- 

 ing. Others are of slight importance. Those which are 

 important ought to be more emphasized. In our experience
