128 AMERICAN GRAPE CULTURE. 



The distance between tlie tiers of arms is 

 about two feet, affording room for canes of 

 that length. 



The next row is seven feet in advance of 

 the first, and the plants two feet apart in the 

 row, as before; this leaves seven and a half 

 feet space for the arms of each vine, with 

 their tiers. The next row stands five feet in 

 advance of the last; and the vines being set 

 three feet apart, gives six feet in length for 

 the arms of each vine. The fourth row has 

 the vines trained on a different plan. See Fig. 

 45. It is four feet in advance of the last, and 

 the vines are set three feet apart. The fifth 

 row is three feet from the last, and is trained 

 on the single arm plan. The vines in this 

 also are three feet apart. This might with 

 about equal propriety have been with double 

 amis at the same distance, with the vines 

 four or five feet apart in the row. 



The object of this graduation, which has 

 probably been already anticipated in the 

 mind of the reader, is to accommodate the 

 vines to the lessening influence of the shelter 

 as the distance from the main wall increases.
