and proceed as before. Irregular corners can then be 

 plotted by sighting to stakes in the larger area. 



In plotting the field for hexagonal planting, the only 

 difference is that double the number of points would have 

 to be established on the sides to give the position of the 

 trees in the alternate rows. 





FIG. 4. Method of Marking Land for Planting. 



Some practice marking both ways with a light furrow-

 by walking to the stakes and dragging a chain or some 

 other convenient marker behind him. Marking the 

 field both ways gives all the points for trees, and, with 

 the stakes reset to facilitate sighting-in the trees, the 

 orchard may be well lined up. In sighting-in the trees,
