recommended and adopted by Fuller. It is about four feet high, 

 and if intended for a single series of horizontal arms with vertical 

 bearing canes, now generally approved. If two series of arms are 

 desired, the height may be increased to seven feet. It consists of 

 durable posts placed ten or twelve feet apart, to which horizontal 

 rails are nailed, the upper one at the top and the lower one about a 

 foot from the ground. Between these, vertical wires, about a foot 

 apart, are stretched as shown in the figure. These wires being 

 shorter than when stretched horizontally, need not be so large, and 

 a saving is thus effected in the expense. Each bearing cane is 

 trained to one of these wires. 



Another mode is to use wires stretched horizontally, as shown in 

 Fig. 425. The lowest should be a foot or more from the ground, 

 and to this the horizontal arms are tied ; the next may be eight or

ten inches above for tying the young shoots, and the two remaining 

 ones, each twelve to sixteen inches higher. These distances are 

 recommended by Strong, in his late work on the Grape. 



Cultivators differ as to the size of the wire suitable to be employed. 

 Some use even as large as No. 8, which is one-sixth of an inch in 

 diameter, and is thirteen feet to the pound. Others severally em- 

 ploy No. 10, which is twenty feet to the pound; No. 12, which is 

 thirty-three feet, and No. 14, which is fifty-four feet to the pound. 

 For the vertical wire trellis, already figured, No. 16 is large enough, 

 which is over one hundred feet to the pound. When the smaller 

 wire is used, it should pass through holes in the end post, and be 

 brought around at the side, and the end twisted around the main 

 part. This may be easily done by using a strong, round piece of 

 wood about a yard long, around which the end is brought, and whicL 

 by using as a roller and lever combined, easily accomplishes or 

 renews the desired tension. 



The wire used for this purpose should be annealed, and is best
