drawn for the spacing of male plants in the vineyard. 
A simple plan, plant a male every third vine on every 
third row. For small vineyards we suggest that one male 
plant be planted for each one to twelve bearing vines. 
The male to be placed as near the center as possible. 
We suggest the following plan for larger vineyards:

Male Spacing Plan 
Heavy line indicates one acre. 
Blocks of nine vines with the male vine in the center 
are used throughout the vineyard. 
These blocks may be extended in all directions. 
These blocks are staggered to give male vines in each 
row.
