LAYING OUT THE ORCHARD. 45 
whole plot is planted. A ten-foot pole may be used in- 
stead of a line or cord to lay out the angle. If exact 
measurements are made there will be little need of 
sighting the rows. 
The guincunz plan is simply to lay out the orchard in 
equilateral triangles. Whatever distance be decided on

between the trees will be the length of the radius of a 
circle, which can be easily swept with a cord of that 
length, or by amarker for this purpose. The fixed mark- 
er is made by nailing two light strips to stakes the width 
apart for the distance from tree to tree. ‘The adjustable 
marker has one of the stakes 
movable on a bar, and fast- 
ened with a key at any de- 
sired distance.

ends, and with braces from 
each point to the middle of 
the opposite side, fastening 
well at the intersections. Having a base line, I move 
this triangle along from one tree to another, making 
holes and setting trees at the points. Repeat the oper- 
ation for each row till the trees are all planted.
