 just as well as those from the upper side. 



I would not recommend this mode of training for 

 vineyard or garden, except in cases like the above, where 

 it is desirable to bring an old, strong vine into the arm 

 system, and the owner has plenty of time, and desires to 

 exercise his skill in bringing the vine into such a form. 

 Vines that have been trained with only two arms may, 

 after they become old, be allowed to produce an extra 

 tier, but the sap will usually flow with greater force into

the upper arms, and necessitate the checking of the 

 canes on them sooner than on the lower ones. To pro- 

 duce a second tier of arms upon a vine having only one 

 tier, the bearing cane nearest the center is allowed to 

 remain at the time of the annual pruning,, and the end 

 cut off at the point where it is desirable to have the arms 

 start. The next season the upper two buds on it are 

 allowed to grow for the arms, and the following season 

 they are laid down for a second tier.
